Technical Specifications
2.1
Product Description
Aspirating smoke detectors from the FAS-420 series are active fire detection devices that are
connected directly to the Local SecurityNetwork (LSN) "improved version" for early fire
detection. They are used for room and equipment protection as well as for monitoring airconditioning units or ducts.
Local SecurityNetwork (LSN) improved
The FAS-420 series aspirating smoke detectors were developed specifically for connection to
the FPA-5000 Modular Fire Panel and offers the upgraded features of the LSN "improved
version" technology.
–
Flexible network structures, including T-tapping with no additional elements
–
Up to 254 LSN-improved elements per loop or stub line
–
Unshielded cable can be used.
The FAS-420 series also offers all the established benefits of LSN technology. The operating
data and fault messages can be read off the FPA-5000 operating and display unit.
Variants
The FAS-420-TP1, FAS-420-TP2, FAS-420-TP1-SL and FAS-420-TP2-SL variants feature LED
displays indicating operating mode, faults and alarms (the FAS-420-TP2 and FAS-420-TP2-SL
have two alarm displays). The FAS-420-TT1, FAS-420-TT2, FAS-420-TT1-SL and
FAS-420-TT2-SL offer differentiated alarm displays (info, pre and main alarm) as well as a 10segment smoke level display (on the FAS-420-TT2 and FAS-420-TT2-SL, all alarm and smoke
level displays are doubled).
The FAS-420-TP1, FAS-420-TP1-SL, FAS-420-TT1 and FAS-420-TT1-SL variants are each fitted
with a detector module.
The FAS-420-TP2, FAS-420-TP2-SL, FAS-420-TT2 and FAS-420-TT2-SL variants each have two
integrated detector modules. Two aspiration pipes can be connected, enabling two areas to
be monitored. This effectively doubles the monitoring area.
Dual-detector dependency
The use of two detector modules in variants FAS-420-TP2 and FAS-420-TT2 also enables a
dual-detector dependency to be realized. This means that one area can be monitored by two
pipe systems.
Two alarm stages
Alternatively, the FAS-420-TP2 and FAS-420-TT2 can have two alarm stages configured. A pipe
system is connected via a pipe adapter on two detector modules. Selecting different response
sensitivities for the detector modules enables the time-staggered triggering of two main
alarms.
Dual-zone dependency
Connecting to the FPA-5000 Modular Fire Panel and programming using RPS software also
permit a dual-zone dependency.
Sensitivity
Three detector module versions are available for the FAS-420 aspirating smoke detector
series:
–
DM-TT-50(80) with a response sensitivity of up to 0.5%/m (0.8%/m) light obscuration
–
DM-TT-10(25) with a response sensitivity of up to 0.1%/m (0.25%/m) light obscuration
–
DM-TT-01(05) with a response sensitivity of up to 0.015%/m (0.05%/m) light obscuration
Depending on the detector module used, the FAS-420-TT1 and FAS-420-TT2 models can
achieve a resolution ten times higher for displaying up to 0.05%/m (0.08%/m), 0.01%/m
(0.025%/m) or 0.0015%/m (0.005%/m) light obscuration. Further sensitivity levels to suit the

application range can be selected via the RPS programming software.
NOTICE!
The sensitivity value is based on measurements with standard test fires (old value in
brackets).
The new High-Power-Light-Source technology permits a broad detection spectrum over all
standardized fires (for response sensitivity, detection points, see Section 3.4 Defining the
Response Sensitivity, page 37).
LOGIC · SENS
The intelligent signal processing LOGIC · SENS distinguishes between deception variables and
fire events in order to prevent false alarms.
Reliable airflow monitoring
Analogous to point-type smoke detectors, which are monitored electronically for wire breaks
and short-circuits, highly sensitive and dependable airflow monitoring is required for smoke
aspiration systems. The airflow sensors used in the FAS-420 series reliably detect
malfunctions such as pipe breakage or obstructions in the air sampling openings.
The small airflow unit also contains a dynamic airflow sensor that enables a response to small
and fast changes in the airflow.
Airflow monitoring is temperature-compensated and can be set depending on the air
pressure.
Patented air sampling openings
The air sampling openings of the pipe system require clearly defined bore diameters that
depend on the planning and design. These precise air sampling openings are created using
patented aspiration reducing film sheets, marking tape, and clips, which not only permit easy
installation, but also prevent "whistling" noises. Another advantage is the quick and easy
detection and checking of the air sampling opening diameters.
Point-type detector projection
The system’s aspiration points can be equated with point-type smoke detectors. The
monitoring areas can therefore be planned in accordance with the applicable national
regulations.
Diagnostics
A system with FAS-ASD-DIAG Diagnostic Software, which enables quick and convenient error
containment, is available for maintenance and service. The current and stored unit status is
read-out via cable data transmission to the PC.
Selecting the fan voltage
The fan voltage for special planning can be increased from 6.9 V to 9 V by relocating the fan
jumper. This increases the air transport speed and therefore reduces detection time.
For -SL variants, the fan voltage can also be set to 6.5 V.

Areas of Application
Thanks to their detection principle, FAS-420 aspirating smoke detectors represent an
extremely versatile fire alarm system.
Principle
Air samples are taken from the monitoring area by a pipe system with defined aspiration
openings and then fed to the detector module.
This is especially well-suited for areas in which point-type detectors cannot be used or can
only be used under certain circumstances. These include:
–
Areas that are difficult to access, in which point detectors are difficult to install and
maintain
–
Air-conditioned areas
–
Areas with a height greater than that allowed for point detectors
–
Areas in which point detectors are not desired for aesthetic reasons
–
Areas in which electromagnetic fields are influential
–
Areas that are exposed to high or low temperatures
–
Areas with contaminated air that require filter elements
–
Areas that must be protected against vandalism.
Space protection
The FAS-420 series is suitable for monitoring areas such as
–
Those with double floors, false ceilings
–
Tunnels, ducts, barely accessible hollow spaces
–
Storage, high-rise warehouses, elevator shafts
–
Museums, cultural institutions
–
Freezer storage.

Figure 2.3 Principle of equipment monitoring with FAS-420 series
aspirating smoke detectors
FAS-420 series aspirating smoke detectors can also be used for early fire detection in areas
with special-purpose air conditioning.
Its high detection sensitivity enables high value goods and equipment to be monitored. The
FAS-420 series is therefore especially suitable for application areas with difficult detection
conditions
–
Where early intervention is essential due to a high concentration value
–
Where equipment must always be operational
–
Where highly-sensitive detection is required (e.g. in areas where, due to built-in filter
elements, the air contains a low concentration of smoke particles)
–
2.3
Where high air-exchange rates prevail.
System Overview
The smoke aspiration systems comprise an aspirating detector and pipe system.
The aspirating smoke detector comprises the detector module for detecting the smoke
aerosols, the aspiration unit for transporting the air samples to the detector module and the
airflow sensor for monitoring the pipe system for breakage and obstructions.
The pipe system comprises essentially pipe and fittings. The standard pipe system is made
from PVC or ABS. The pipes used for equipment monitoring should be halogen-free.
Each air sampling opening in the pipe system represents a point detector in the planning.

To guarantee reliable operation even under the most difficult conditions (clean rooms,
recycling area), there are numerous accessories available, such as air filters, water separators
and detonation safety barriers.
2.4
Functions
Air samples are taken from the area to be monitored using the aspiration unit. They are fed via
a pipe system with defined air sampling openings to the sensitive detector module (see
Figure 2.4).
Detector module
Depending on the response sensitivity of the detector module in use and programmed alarm
threshold, the FAS-420 series aspirating smoke detector triggers the alarm when the
corresponding light obscuration threshold is reached. With the FAS-420-TP1 and the FAS-420TP2, the alarm is displayed via the alarm LED and/or two alarm LEDs on the unit and
transmitted to a connected fire panel. The FAS-420-TT1 and FAS-420-TT2 versions offer
differentiated LED displays for info, pre and main alarm. Pre and main alarms are transmitted
to the fire panel (with FPA-5000 Rel 2.1; additionally with info alarm from Rel 2.5 or above).
Various delay times can be programmed for the alarm thresholds, as well as for displaying and
transferring malfunctions (see Section 4.3 Settings on the Unit Motherboard, page 67). Alarm
messages are saved and are reset after the cause has been eliminated.
LOGIC · SENS
The LOGIC · SENS intelligent signal processing compares the measured smoke level with
known disturbance variables and decides between alarm and deception. LOGIC · SENS can
be activated and/or deactivated using the RPS programming software.
Detector module monitoring
Each detector module is monitored for contamination, signal malfunction and removal. Soiling
of the detector module has no effect on its sensitivity. With all variants, any malfunction is
displayed via the malfunction LED and transferred to the fire panel. Malfunctions caused by
brief environmental fluctuations can be eliminated with a time-delayed setting.
Airflow monitoring
An airflow sensor checks the connected pipe system for breakage and obstruction. The
airflow sensor can – depending on the configuration of the pipe system (see
Section 3.2 Principles of Pipe Planning, page 33) – detect at least a 50% obstruction to a
complete obstruction of the air sampling openings and a breakage in the pipe system that
results in a 50% loss from the air sampling openings. Should the fan fail, the airflow in the
pipe system is interrupted and this causes a blockage message. Airflow monitoring is
temperature-compensated and can be set depending on the air pressure.

On expiry of a defined delay, the malfunction is displayed on the aspirating smoke detector
and the message is transmitted to the fire panel. The monitoring window thresholds can be
modified to suit the environmental conditions (see Section 3.3 Airflow Monitoring, page 36).
The principal signal curve of the airflow sensor is indicated in Figure 2.5.

case of malfunctions
Fault Indication
An imminent detector module or airflow malfunction generates a malfunction message that is
displayed on the FAS-420.
Flash code for malfunction detection
Malfunctions and certain device statues are displayed using various LED flash codes on the
detector module's electronics PCB. Thus it is possible to differentiate quickly among
malfunctions that can be caused by a defective detector module, an obstruction, or a break in
the pipe system.
Resetting via fire panel
A malfunction message is reset via the connected fire panel. Alarm and malfunction messages
are displayed simultaneously on the unit via the Local SecurityNetwork LSN using the reset
function on the detector line.
Calibrating the airflow sensor
Automatic airflow sensor calibration makes it significantly easier to start the FAS-420. The
initialization phase is carried out according to or independently of the air pressure as desired.
To set the FAS-420 to the airflow typical for the pipe network, an airflow initialization (flowinit) procedure is carried out. This must be done for each unit once at the start after
installation, each time the pipe system is replanned/redesigned and after changing the fan
voltage. This enables the unit to determine and save the airflow typical for the pipe network.
Pipe system
A pipe system with an overall length of up to 300 m can be connected to FAS-420 series
aspirating smoke detectors over a maximum of 32 aspiration points. Two pipe systems can be
connected to both the FAS-420-TP2 and FAS-420-TT2 variants. The entire pipe system then
has a total length of 2 x 280 m and a maximum number of 2 x 32 aspiration points.

FAS-ASD-DIAG Diagnostic Software
The diagnostic software enables the saved and the current unit status, as well as the error
messages to be displayed on the PC or laptop.
The supplied diagnostics cable connects the aspirating smoke detector ("DIAG" connection on
the motherboard) to the PC. The FAS-ASD-DIAG version is connected to the PC via a USB
port, earlier DIAG versions use a COM port (see Figure 2.10).
Windows 2000 or Windows XP can be used as the operating system (earlier diagnostic
software versions (with serial interface) run under WINDOWS 95, 98, ME, 2000 and NT). For
correct color display, the monitor and graphics card must be able to display more than 256
colors.
DIAG
Figure 2.10
Diagnostic software for reading out device states
Diagnostic messages remain saved in the diagnostic software for at least 3 days in order to be
able to evaluate even short, sporadically occurring errors (e.g. in case of changed operating
conditions).
Resetting the device via the diagnostic software deletes all saved diagnostic messages.
The software also allows the deletion of error messages.
NOTICE!
The diagnostic software can be used to save all stored and current diagnostics data, as well as
the settings made via the RPS programming software as a file. To be able to compare the data
read out, save each file under a different file name.
2.5.6
Remote Indicators
A remote indicator must be connected if the aspirating smoke detector is not directly visible
or has been mounted in false ceilings or floors.
The external detector alarm display must be mounted in an obvious place in halls or entrances
of the building section or areas concerned.
The display is connected to the unit motherboard via the "X6 ext. Display" (D-/D+/V-/V+). Only
digital remote indicators made by Wagner can be used for this connection; these are available
by separate order.
Alternatively, FNS-420-R LSN Strobes can be connected via LSN and configured via
FSP-5000-RPS.

Absorption of the operating noises caused by airflows
Vibration absorbers
The fans of the aspirating smoke detectors cause a noise level of approx. 45 dB(A). Mounting
the FAS-420 onto vibration absorbers can effectively reduce noise transmission through the
installation elements. This results in a reduction in the noise level from 1 to 2 dB(A).
Additional operating noises may be caused by vibrations on the pipe system, which are
generated by the air flowing through it. This can be remedied by inserting a corrugated hose
(approx. 15 cm long) between pipe system and aspirating smoke detector to create a flexible
transition (see Figure 2.12).
In noise-sensitive areas, the sound level can also be reduced by installing a piece of plastic
pipe approximately 100 mm long into the air outlet opening of the unit. This is done by
breaking out the pre-punched opening in the protective grille (e.g. using a small edge cutter).
All -SL variants are equipped with an extremely quiet fan that limits the noise level to
38 dB(A). Thanks to the additional sound damper, fan noise can be reduced to 34 dB(A); this
ensures that the detector is in accordance with DIN 4109 for living and sleeping areas.

Pipe system components
During planning/design, a distinction is drawn between area monitoring and equipment
monitoring. For both applications, PVC and halogen-free pipes can be used , but the
restrictions of EN 54-20 must be observed. Halogen-free pipes should be used when
monitoring equipment.
Figure 2.13 shows essential accessory components that can be selected for the application
concerned.
The pipe system must be constructed using pipes with an external diameter of 25 mm and the
associated fittings.
If the maximum permissible pipe lengths are used, then for the pipe returns, pipes with an
exterior diameter of 40 mm and the appropriate fittings must be used (see also
Section 3.9 Planning for Long Pipe Feed Lines, page 58).
Blowing-out system
In areas that are susceptible to dust particles or icing, it may be necessary to blow out the
aspiration pipe system and its air sampling openings. Figure 2.14 shows a manual blowing-out
system with a three-way tap.

Air sampling openings
Aspiration reducing film sheets
An air sampling opening is a 10 mm bore in the aspiration pipe that is covered with a patented
aspiration reducing film sheet with the required opening diameter. The size of the opening
depends on the construction of the pipe system (see Section 3 Planning, page 32).
The aspiration reducing film sheet is secured with marking tape to prevent it from becoming
displaced. The marking tape is a transparent sticky film with red edges and a 10 mm hole. It is
placed over the aspiration reducing film sheet so that the air sampling opening is not
concealed and can be seen from long distances.

As the clips are more stable under pressure and the elastic rubber insert significantly
improves the cleaning effect, they are used for all plans and designs which require a blow-off
system due to environmental influences (e.g. increased exposure to dust).
The standard AF-x aspiration reducing film sheets and the marking tapes are not suitable for
use in low-temperature areas.
The aspiration reductions with plastic clips are available separately.

Ceiling lead-throughs
A concealed pipe system for area monitoring can be realized by installing in a false ceiling.
This requires the use of ceiling lead-throughs in the false ceiling. The ceiling lead-through can
be used with a false ceiling thickness of up to approx. 35 mm.
According to the planning and design guidelines, the ceiling lead-throughs are fitted with
aspiration reducing film sheets with defined air sampling openings and connected to the pipe
system by means of aspiration hoses (see Figure 2.17).
If these hoses exceed a maximum of 1 m in length, the plan according to Section 3 Planning
applies. If structural circumstances dictate that lengths in excess of 1 m are used, the pipe
system has to be calculated accordingly.

Principle of air return
If the aspirating smoke detectors and the pipe system are installed in areas with varying air
pressure, the aspirated air must be returned to the pressure area of the pipe system (see
Figure 2.18). The air-return pipe can serve to equalize pressure or to prevent atmospheric
loads (e.g. odors) in neighboring spaces.

FAS-ASD-WS Water Separator for condensing water
vapor and collecting condensate from the pipe system
The FAS-ASD-WS Water Separator is integrated at the lowest point in the pipe system
upstream of the air filter and the aspirating smoke detector. The 45° pipe elbow permits
optimum distance from the wall (see Figure 2.20).
The FAS-ASD-WS Water Separator can be operated in a temperature range from 0 °C to
+50 °C. The sintered metal filter in the water separator has a pore width of 50 µm and causes
an additional rough absorption of soil particles.
The FAS-ASD-WS is supplied with an angle support and PG cable glands. The 45° pipe elbows
(4 units) must be ordered separately.

Detonation safety barrier
Detonation safety barrier in the aspiration pipe system
and if necessary in the air-return pipe
Vapor/air and/or gas/air mixture ignition in the aspirating smoke detector may result in pipe
explosion or detonation. This depends on the composition, concentration, temperature, and
pressure of the flammable mixture.
The detonation safety barrier is a flame trap that is flame-proof in the face of pipe explosions
(deflagrations) and detonations (see Figure 2.21).
In normal operation, the steam and gas mixtures flow in any direction through the safety
barrier. An ignition of the mixture in the upstream aspirating smoke detector will cause the
developing detonation to be arrested. Ignition is prevented by the flame filter. Combustion of
the mixture in the flame filters may cause a rebound of the detonation front. To prevent this, a
minimum pipe length of 1.0 m between the installation point of the detonation safety barrier
and a possible ignition source (aspirating smoke detector) must be maintained. Permanent
fire prevention is thus achieved indirectly.
CAUTION!
The connecting pipe between the aspirating smoke detector and the detonation safety barrier
must be made of metal. During installation, care must be taken to ensure that the threaded
connections are bolted together gas-tight using synthesol or sealing tape.

Plans not contained in the operation guide must be requested.
Principles of Pipe Planning
The aspiration pipe network must be designed such that all possible fires in the monitoring
area can be dealt with at an early stage.
The number of air sampling openings and the structure of the pipe system depend on the size
and geometry of the monitoring range. The pipe system must be laid out according to the
planning guidelines in this chapter, taking into account the following issues:
Symmetrical structure
The pipe system should preferably have a symmetrical structure, i.e.
–
Same number of air sampling openings per pipe branch
–
Same pipe branch lengths (should not exceed ± 20% deviation)
–
Same distance between neighboring air sampling openings on the smoke aspiration pipe
(should not exceed ± 20% deviation).
Asymmetrical structure
If structural circumstances dictate that the pipe system is to be designed asymmetrically (see
Figure 3.1), the following conditions apply:
–
The number of air sampling openings and the length of the shortest and longest pipe
branch within the pipe system must not exceed a quantity ratio of 1:2.
–
The distance between neighboring air sampling openings on the smoke aspiration pipe
must be equal (should not exceed ± 20% deviation).
–
The diameters of the air sampling openings are determined separately for each pipe
branch. The diameters depend on the total number of air sampling openings in the pipe
branch in question.
Figure 3.1 shows a typical U-pipe system with three or six air sampling openings and the air
sampling opening diameters calculated according to Section 3.6 Standard Pipe Planning.

Pipe diameter
As a rule, the pipe system is created using pipes with a 25 mm diameter. Both PVC pipes and
halogen-free pipes can be used, however, ensure that you comply with the restrictions of
EN 54-20. Halogen-free pipes are to be used in preference for equipment monitoring.
In many applications, greater distances between the aspirating smoke detector and the
aspiration pipe must be bridged. This is done using pipes with greater diameters (40 mm),
which guarantees maximum planning (see also Section 3.9 Planning for Long Pipe Feed Lines,
page 56). However, pipes with greater diameters restrict the length of the pipe system.
Longer pipe feed lines
Branch length
To achieve short transport times for the smoke aerosols in the aspiration pipe and thus quick
detection, it is better to plan several short branches than fewer long ones (preferably U and
double U-pipe system).
Pipe configurations
Depending on the area geometry, five pipe configurations can be selected (see Figure 3.2):
–
I-pipe: pipe system without branches.
–
U-pipe: pipe system that branches into two pipe branches.
–
M-pipe: pipe system that branches into three pipe branches.
–
Double U-pipe: pipe system that branches symmetrically into four pipe branches.
–
Quadruple U-pipe: pipe system that branches symmetrically into eight pipe branches.

If elbows or bends are used, the maximum total length of the pipe system is reduced.
NOTICE!
It is preferable to use pipe bends rather than pipe elbows.
The detection time will be influenced significantly by too high a number of changes of
direction.
Special cases
If the pipe system does not correspond to the planning guidelines described here owing to
structural circumstances, it must be calculated separately for the case in question on request.
Testing
For critical applications, test the secure detection with activation attempts. Check also
whether there is airflow at the individual air sampling openings.
NOTICE!
In order to increase transport speed in critical application areas, the fan voltage can be
increased from 6.9 V to 9 V.

Two alarm stages
To implement two alarm stages, a pipe adapter for the aspiration pipe system is required. The
two detector modules in the aspirating smoke detector require different response

sensitivities.

3.3
Airflow Monitoring
EN 54-20 requires the detection of a 20-percent change in the airflow volume by the detector
module's airflow sensor. In order to achieve this, the activation threshold of the airflow sensor
must be set to level II. Alternatively, level I can also be used. It is recommended that airflow
calibration is carried out dependent on air pressure for both of these settings. In systems that
do not need to comply with EN 54-20, any threshold can be set. The smoke aspiration pipes
are planned taking into account the applicable national regulations for the country concerned.
Adapting the airflow sensitivity
The sensitivity of the airflow sensor must be adapted to the application. For example, a long
pipe system requires a sensitive setting of the airflow sensor. The activation threshold and
thus the sensitivity of the airflow sensor can be set on 4 levels. Breakages and obstructions
must be accurately detected in the event of a malfunction.

Dynamic airflow sensors
The airflow monitoring of the unit makes it possible to detect breaks at the end of pipes and
identify sudden obstruction of individual air sampling openings (e.g. following tampering with
the pipe system). Because these dynamic airflow sensors are only active if level I was selected
for the airflow monitoring, the points outlined under "Level I restrictions" must be taken into
consideration.
Restrictions
Airflow monitoring may only be set to level I if
–
planning was carried out in accordance with "single-hole monitoring" (see Chapter 4.3.1
–
the airflow sensor was calibrated dependent on the air pressure (see Chapter 7.1.2
–
and no larger airflow fluctuations can occur.
"Pipe Planning for Single-Hole Monitoring"),
"Airflow Calibration according to Air Pressure")
Air pressure differences
There must be equal air pressure along the length of the aspiration pipe.
NOTICE!
If the aspirating smoke detectors and the pipe system are positioned in areas with different
air pressures, the air aspirated by the FAS-420 must be returned to the pressure area of the
pipe system (see Section 2.6.4 Air-Return Pipe for Pressure Areas and Atmospheric Loads,
page 24).
3.4
Defining the Response Sensitivity
The sensitivity of smoke aspiration systems can be divided into certain fire sensitivity classes
in accordance with EN 54-20. These fire sensitivity classes describe specific examples of ways
in which the systems can be applied. The permissible system plans given in Section 3.6 can be
determined for each classification.Smoke aspiration systems with a higher fire sensitivity
class according to EN 54-20 also satisfy the requirements of the lower classes.

The maximum monitoring area of an air sampling opening corresponds to the monitoring area
of point-type detectors in accordance with the applicable planning guidelines.
The maximum total monitoring area, the maximum total pipe length and the maximum number
of air sampling openings depend on the selected planning. They are also dependent on the
restrictions imposed by national regulations.
Depending on the planning selected, some restricted values may apply.
The values for the maximum number of air sampling openings, the maximum pipe length and
the maximum overall monitoring areas apply for each pipe system. Two pipe systems can be
connected to aspirating smoke detectors FAS-420-TP2 and FAS-420-TT2, each with two
detector modules.

Standard Pipe Planning
In order to plan in accordance with the EN 54-20 standard, certain factors must be known,
such as the system sensitivity requirements, the number of air sampling openings and the
accessories needed for the application concerned. These factors can be used to determine
the appropriate standard-compliant construction of the pipe system using the following
chapter and the planning table in the appendix.
3.6.1
Determining the Necessary Accessories
As accessory components, e.g. filters, have a particular effect on the dimensions of pipe
planning, the appropriate accessory must be selected for the application concerned in
advance. Retrofitting an accessory, e.g. a fine filter, is largely only possible if a sensitive
detector module is used or if a certain contingency is planned in advance.
The following components must be taken into account in this regard:
–
Air filter
–
Water separator
–
Three-way-tap
–
Detonation safety barrier
See Section 2.8.4
3.6.2
Pipe Planning with Pipe Accessories
For the purpose of pipe system planning, the following planning table is available for all
selected pipe accessories.
–
Planning without air filter
–
Planning with FAS-ASD-FL air filter
NOTICE!
In order to improve the detection quality of a smoke aspiration system, an area can be
monitored with more detection points than required by national guidelines. However, to
calculate the necessary sensitivity of an aspirating smoke detector, the number of aspiration
points required by the standard must be used.

Pipe Planning for Single-Hole Monitoring
Depending on the pipe configuration, the following system parameters are used to detect a
single air sampling opening or a particular number of obstructed air sampling openings.
Planning is to be carried out according to regulations specified in Section 3.6 Standard Pipe
Planning. Additionally, the following limiting values and opening diameters must be observed.
An additional accessory (air filter, condensate separator etc.) can have an effect on the
maximum pipe length.

Simplified Pipe Planning
Simplified planning is used for equipment protection and in premises with smaller
dimensions. The benefit of this type of planning is the standard diameters of the suction
openings.
Planning is to be carried out according to regulations specified in Section 3.6 Standard Pipe
Planning. Additionally, the following limiting values and opening diameters must be observed.
An additional accessory (air filter, condensate separator etc.) can have an effect on the
maximum pipe length.

Planning with Acceleration Openings
Acceleration openings
In order to meet individual regulations, it may be necessary to increase the transport time of
the systems. This can be fulfilled by fitting the ends of the pipe branches with acceleration
openings, which increase transport speed. Depending on the regulations concerning
transport time, it may be necessary to dimension an acceleration opening with the same or
double the diameter of the last air sampling opening on a pipe branch. Only authorized aids
should be used to calculate the transport time.The additional airflow of the acceleration
openings also reduces the sensitivity of the air sampling openings. If required, this reduction
can be offset as follows:

Table 3.2 Factors for increasing the sensitivity (acceleration opening corresponds to two air sampling openings)
Example:
A class B double U-pipe system with 24 air sampling openings is planned. According to EN
54-20, 24 openings are permitted in class B at a sensitivity of 0.25% LT/m. In order to increase
the transport time, an acceleration opening the same size as the last air sampling opening is
to be used.According to Table 3.1, the necessary sensitivity of the detector module in this
case is
0.25 % LT/m * 0.85 = 0.1875 % LT/m.
2. option: reducing the number of air sampling openings
Reduced sensitivity at the air sampling openings can be offset by reducing the number of air

Planning for Forced Airflow
Monitoring the air-conditioning ducts
Air-conditioning units are broken down into low and high-speed units (see table below). The
details provided in this chapter apply only to low-speed units. There are no adequate
empirical values available for high-speed units. Hence, smoke trials must be executed for airconditioning ducts with flow speeds above 10 m/s, in order to determine optimal response
behavior.

The exhaust duct should be selected as the installation location of the pipe system, as far as
possible away from the sound dampers, air baffles and bends. The distance from such
“obstacles” should be at least three times the smallest duct diameter.
If it is absolutely essential to install the pipe system directly behind air baffles, sound
dampers or bends; the main speed ranges must be monitored (see Figure 3.21/Figure 3.22).

When installing a pipe system in air-conditioning ducts, the following must be observed:
–
Since the FAS-420 and the pipe system are located in different pressure ranges, an airreturn pipe (see next page) must be provided.
–
The pipe entries into the duct must be airtight.
–
The portion of the pipe system that is outside the duct must be sealed airtight.

Offset arrangement of the air return
If the distance of 2 m cannot be adhered to, the pipes must be arranged offset. This way, a
pressure fall between intake and exhaust can be achieved since the pipes are located in
different speed ranges (see Figure 3.24).
The distance of the air sampling openings to one another and to the duct wall is represented
in the following table.

The pipe is closed with an end cap without bore hole.

The air sampling openings must face the airflow (see Fig. 5.4).
Note when planning that the air-conditioning ducts are often only accessible from two sides
for installation of the pipe system.

Power Supply
To measure the power supply, the detector-ready state of the security system and the alarm
case are regarded. When the system is ready to detect, the power supply must provide the
standby current for the aspirating smoke detectors and ensure the emergency power
rechargeable battery is charged in accordance with DIN VDE 0833, part 1 (80% charged in
24 hrs).
Current calculation
The current in the event of an alarm is calculated according to the following formula:
Space protection
Ig = IA x nmax + IQ x (n - nmax) ≤ IPSmax
Equipment protection
Ig = IA x √n + IQ x (n - √n) ≤ IPSmax
Charging current
The current required to charge the battery is calculated using the formula below (for space
and equipment protection):
IL =
0,8 x Kn

Ig = IQ x n + IL ≤ IPSmax
where

Installation of the Pipe System
At the very least, the pipes and fittings used for the pipe system must comply with class 1131
according to EN 61386-1, 2004.Class 1131 requires the following of the pipe system in use:
Features
Compression resistance
Shock resistance
Temperature range
Severity
125 N
0.5 kg, drop height of 100 mm
-15 °C to +60 °C
The pipe system must be constructed using the following pipes and the associated fittings:
Exterior diameter
Smoke aspiration pipe
25 mm
Internal diameter
ABS
PVC
21.4 mm
21.2 mm
For pipe systems with long pipe feed lines (see also Section 3.9 Planning for Long Pipe Feed
Lines, page 56), you must also use the following pipes and the associated fittings:
Exterior diameter
Smoke aspiration pipe
40 mm
Internal diameter
ABS
PVC
35 mm
36.2 mm
NOTICE!
When constructing the pipe system, observe the temperature range specified under
Section 2.8.3 Pipe system, page 30 in the Technical Specifications chapter.
The pipe system must be constructed according to planning specifications and taking into
account the planning guidelines (see Section 3 Planning).
1.
Shorten the pipes with a pipe-cutter (38 mm) or a metal saw. Deburr the joints and clean
up the chips.
2.
Before gluing, clean the adhesion points with the prescribed cleaning agent (Tangit) to
remove dirt and grease. Use the Tangit adhesive to glue the pipe transitions with the
appropriate fittings so that they are airtight.
NOTICE!
If halogen-free plastics must be used, the installation procedures may vary depending on the
selected material:
–
ABS is glued
–
Polypropylene (PP) is welded
–
Polyamide (PA) is pushed together and bolted.
3.
Minimize pipe lengths and changes of direction. Pipe elbows have an extremely high flow
resistance. Therefore, they should be used only where they cannot be avoided for
structural engineering reasons. If necessary, reduce pipe lengths in proportion to the
pipe elbows used.
NOTICE!
Pipe bends must be given preference over pipe elbows. Too many changes of direction can
cause an airflow malfunction in the FAS-420 and have a negative impact on the detection time.
As a benchmark, a pipe bend corresponds to a straight pipe length of 0.3 m. An elbow
corresponds to a straight pipe length of 1.5 m.
4.
Fix the pipe system. It must not sag or be possible to move it. Fasten the pipes with pipe
clips without rubber inserts. The distance between the pipe clips should not exceed
80 cm. At high temperatures, reduce the distance between the pipe clips to a maximum
of 30 cm.

75
NOTICE!
Do not use pipe clips with rubber inserts since these do not allow length extensions and the
pipe system may bend or even tear.
5.
Close open pipe ends with an end cap.
NOTICE!
On completion, test the pipe system:
5.1
–
For leaks
–
For fault-free connections
–
For correct planning of the air sampling openings.
Length Change of the Pipe System
Length changes to the pipes are caused by temperature changes. Temperature increases
cause lengthening of the pipes, temperature drops cause shortening of the pipes. The length
change must be given particular consideration if the temperature of the pipe system at the
time of installation deviates from the normal operating temperature.
The length change can be calculated using the following formula:
ΔL = L x ΔT x δ

For example, a temperature change of 10 °C on a 10 m-long PVC pipe causes a length change
of 8 mm.

PVC pipe clips are used as standard for installing the pipe system. These clips do not allow
any length extensions.

Figure 5.9 Installing the three-way tap
The three-way tap is required to blow out the pipe system with blast air (as a preference) or
compressed air (compressed air is compressed, non-purified and humid ambient air. Blast air,
in contrast, is purified and dehumidified air. If the FAS-420 and pipe system are located in
areas with temperatures below freezing, blast air is to be used for blowing out). The
aspirating smoke detector and the downstream pipe system accessory components (e.g. air
filter) must not and cannot be blown-out.
A check valve for relieving pressure from the pipe system must be fitted to the end of each
pipe branch. The check valve prevents damage to the air sampling openings and prevents dirt
deposits from being blown through the pipe system.
To prevent aspiration reducing film sheets in deep-freeze areas from tearing, it is advisable to
use special deep-freeze aspiration reductions.
Check valve and deep-freeze aspiration reductions are available on separate order.
Connections
Fasten the three-way tap using the transition screw connections in the pipe system.
During installation, note the assignment of the connections:
–
Install the aspiration pipe system on connection C.
–
Install the FAS-420 on connection A.
–
Attach the compressed air supply (compressor or mobile blowing-out system) to
connection B of the three-way ball valve.
NOTICE!
A single blowing-out process can be completed within 50 seconds. If within this time the unit
is still connected to the pipe system, the malfunction message “airflow sensor module
malfunctioning” will not be evaluated. If the blowing-out process has to be repeated (steps 1
to 3), wait at least 120 s.
The manual blowing-out process on the pipe system is carried out as follows:

1.
Position the tap lever so as that the blast air and pipe system (B-C connection) are
connected.
The connection to the FAS-420 must be blocked for blowing-out!
Manually blow out the pipe system for approximately 10 seconds.
2.
Set the lever of the tap such that the device is not connected with the pipe system or
with the connection for the blast or compressed air supply. Wait approximately 20
seconds so that dust and dirt raised in the pipe system can settle and thus will not be
sucked through the aspirating smoke detector.
3.
Reconnect the blown-out pipe system to the FAS-420 within a further 10 seconds by
switching the tap accordingly (A-C connection).

Calibrating the Airflow Sensor
NOTICE!
The aspirating smoke detector must be operated for at least 30 min prior to the airflow being
initialized to bring it up to operating temperature.
Described below is the procedure for calibrating the airflow sensor, both irrespective of air
pressure, i.e. in simplified form, and depending on air pressure. Restrictions for the simplified
procedure are contained in Section 3.3 Airflow Monitoring, page 36.
For an air-pressure-dependent calibration, use the air pressure correction tables in the
appendix (Section 8.2 Air Pressure Correction Tables for Airflow Sensor Calibration,
page 105).
To be able to judge the airflow sensor value correctly during start-up work, always adhere to
the type of calibration in the test log.

NOTICE!
A hardware defect in the detector module is indicated by a permanently-lit detector module
LED.
7.4
Pipe system
Check the pipe system and the air sampling openings for obstruction in areas susceptible to
dust particles or icing. Where necessary, blow out the pipe system and air sampling openings
using blast air (class 3 for recycling areas or class 2 for deep-freeze areas). Use a mobile
cylinder of compressed air (blowing-out system) or activate the manual blowing-out system
located on site. The components (compressors, compressed air containers, dryers) required
to supply the compressed air can be obtained directly from the relevant compressed air
system suppliers.
CAUTION!
Before blowing out the pipe system, disconnect the FAS-420 from the pipe system; otherwise,
the airflow sensor will be damaged.
Blowing out
The compressed air supply to the pipe system must be connected so that only the pipe
system itself is blown out. The aspirating smoke detector and the downstream accessory
components of the pipe system (e.g. air filter) must not and cannot be blown out.
A check valve must be installed at the end of each pipe branch. The check valve prevents
damage to the air sampling openings and prevents dirt deposits from being blown through the
pipe system. To prevent aspiration reducing film sheets in deep-freeze areas from tearing, it is
advisable to use special deep-freeze aspiration reductions.
The compressed air supply and compressed air connection must be installed so that at least
0.7 bar of pressure remains available per pipe branch within the pipe system. This means a
minimum of 0.7 bar for the I-pipe, a minimum of 1.4 bar for the U-pipe and a minimum of 2.8
bar for the double U-pipe. The minimum flow cross-section within the compressed air
connection must be taken into consideration. If the connection is made, e.g. via a quick
release coupler with a flow cross-section of 7.2 mm, an approx. pressure ratio of 1:9 occurs
due to the comparatively large flow cross-section within the pipe system (21.4 mm). If, for
example, 8 bar of pressure is available at the quick release coupler, this would drop to
approx. 0.9 bar due to the larger flow cross-section in the pipe system. In this case, the
pressure would still be sufficient for an I-pipe system, but inadequate for U and double U-pipe
systems.
In plants where contamination of the pipe system/air sampling openings can be expected, the
compressed air supply can be connected via a three-way tap. In plants exposed to heavy
contamination (e.g. recycling plants) an automatic blowing-out system is recommended.
For areas exposed to moderate contamination, in which blowing out is required only at
prolonged intervals, the use of a mobile blowing-out system including refillable compressed
air cylinder is recommended.
7.5
Check the airflow sensor calibration
Check the airflow sensor value with the Diagnostic Software.
Functional principle
During initialization of the connected pipe system, the device saves the measured actual value
of the airflow as a target value via the integrated airflow monitoring. This target value then
serves as a reference value for the additional evaluation of any airflow malfunctions.

en | Maintenance
Depending on the airflow threshold selected (see "Adapting the airflow sensitivity" in
Section 3.3 Airflow Monitoring, page 36), the current airflow value during operation can
fluctuate around this target value without triggering an airflow malfunction. Only if the
selected airflow threshold is exceeded will the airflow malfunction be reported by the device
and thus transmitted.
Checking the current value
The tolerance range of the selected airflow threshold and the actual and target values are
represented in the diagnostic software. The boundaries (maximum/minimum) always
correspond to a deviation of ±100 % from the saved target value.
Check the deviation of the actual value from the target value. If there is a deviation of > ±70 %,
you should make a prophylactic check of the pipe system (see section below on
"Troubleshooting airflow malfunction").
NOTICE!
When the fire panel is in revision mode, the LOGIC·SENS is temporarily deactivated, allowing
the detector modules to be checked quickly and directly.
Dependent on air pressure
To ensure long-term malfunction-free operation of the device, the airflow sensor must be
calibrated according to the air pressure. Only with this type of calibration do low air pressure
fluctuations remain within the monitoring window and thus in the permissible tolerance
range.
Independent of air pressure
If the sensor calibration is carried out independently of air pressure, fluctuations in the air
pressure can cause undesired airflow malfunctions. The calibration of the airflow sensor may
only be carried out this way if you ensure that no fluctuations in air pressure will occur in the
immediate environment.
CAUTION!
If air pressure fluctuations are anticipated in the immediate environment, the airflow sensor
must be calibrated dependent on air pressure (see also Section 3.3 Airflow Monitoring,
page 36).
Troubleshooting airflow malfunction
If the airflow calibration has been executed depending on air pressure and the actual value
still does not lie within the tolerance range of the selected airflow threshold (airflow
malfunction displayed on the device), then a type of disturbance value other than air pressure
or temperature fluctuation exists.
CAUTION!
In case of a defect in the airflow monitoring, only authorized personnel may replace the
detector module!
1.
In this case, check the pipe system for leaks and obstructions (see Section 6.5 Checking
Airflow Monitoring, page 90, "Troubleshooting").
2.
If this check reveals no malfunctions, check the airflow monitoring by connecting the test
pipe and conducting the functional test in accordance with Section 6.6.2 Conducting the
Functional Test.
3.
If, during troubleshooting, the pipe network has been changed, the original configuration
of the pipe network must be restored after the troubleshooting has been completed and
the airflow must be recalibrated.

NOTICE!
It is essential that you adhere to the calibration type (air-pressure-dependent or air pressureindependent) and, if necessary, the values for air pressure, height above sea level, and set
voltage on MP1/MP4 in the test log.
1.
Observe the current airflow value during ongoing maintenance or check it at the latest
during the next inspection.
2.
If the target value is similar to the previous one, disruptive environmental influences are
the cause of the deviation. If these negative influences on the airflow monitoring cannot
be suppressed, the next less-sensitive threshold should be set.
NOTICE!
The diagnostic software can be used to save all stored and current diagnostics data, as well as
the settings made via the RPS programming software as a file. To be able to compare the data
read out, save each file under a different file name.
