ADT-HRSI

Intelligent Heat Detector

SPECIFICATION DATA

DESCRIPTION

Honeywell's Signature Series Model ADT-HRSI Intelligent

Heat Detectors gather analog information from their fixed

temperature and/or rate-of-rise heat sensing elements and

converts it into digital signals. The detector's on-board

microprocessor measures and analyzes these signals. It

compares the information to historical readings and time

patterns to make an alarm decision. Digital filters remove

signal patterns that are not typical of fires. Unwanted alarms

are nearly eliminated.

The microprocessor in each detector provides four additional

benefits; self-diagnostics and history log, automatic device

mapping, stand-alone operation and fast, stable

communication.

Self-diagnostics and History Log:

Each Signature Series detector constantly runs self-checks

to provide important maintenance information. The results

of the self-check are automatically updated and permanently

stored in the detector's non-volatile memory. This information

is accessible for review any time at the control panel, PC, or

by using the SIGA-PRO Signature Program/Service Tool.

The information stored in the detector's memory includes:

- Detector serial number, address, and type

- Date of manufacture, hours of operation, and last

maintenance date

- Current detector sensitivity values and the extent of

environmental compensation

FEATURES

• 70ft (21.3 meter) spacing

• 9°C (15°F) per minute rate-of-rise and 57°C (135°F)

fixed temperature alarm threshold

• Intelligent detector with integral microprocessor

• Non-volatile memory

• Automatic device mapping

• Electronic addressing

• Identification of defective detectors

• Twin status LEDs

• Standard, relay, and fault isolator mounting bases

• Designed and manufactured to ISO 9001 standards

- Original detector sensitivity values upon manufacturing

- Number of recorded alarms and troubles

- Time and date of last alarm

- Analog signal patterns just before the last alarm

- Up to 32 possible trouble codes which may be used to

diagnose faults.

In the unlikely event that an unwanted alarm does take place,

the history file can be called up to help isolate the problem

and prevent it from happening again.

Automatic Device Mapping:

The loop controller learns where each device's serial number

address is installed relative to other devices on the circuit.

This "mapping" feature provides supervision of each device's

installed location to prevent a detector from being reinstalled

(after cleaning etc.) in a different location from where it was

originally. The history log for the detector at its original

location remains relevant and intact.

The Signature Series Data Entry Program also uses the

mapping feature. With interactive menus and graphic

support, the wired circuits between each device can be

examined. Layout or "as-built" drawing information showing

wire branches (T-taps), device types and their address are

stored on disk for printing hard copy. This takes the "mystery"

out of the installation. The preparation of "as-built" drawings

is fast and efficient.

Device mapping allows the Signature loop controller to

discover:

- Unexpected additional device addresses

- Missing device addresses

- Changes to the wiring in the circuit.

Stand-alone Operation:

A decentralized alarm decision by the detector is guaranteed.

On-board intelligence permits the detector to operate in

stand-alone mode. If loop controller CPU communications fail

for more than 4 seconds, all devices on that circuit go into

stand-alone mode. The circuit acts like a conventional alarm

receiving circuit. Each detector on the circuit continues to

collect and analyze information from its surroundings. The

ADT-HRSI detectors alarm if the ambient temperature

increases 57°C (135°F) or if the temperature increases at a

rate exceeding 9°C (15°F) per minute. If the detector is

mounted to a relay base, the relay operates.

Fast Stable Communication:

On-board intelligence means less information needs to be

sent between the detector and the loop controller. Other than

regular supervisory polling response, the detector only needs

to communicate with the loop controller when it has

something new to report. This provides very fast control

panel response time and allows a lower baud rate (speed) to

be used for communication on the circuit.

The lower baud rate offers several advantages including:

- Less sensitivity to circuit wire characteristics

- Less sensitivity to noise glitches on the cable

- Less emitted noise from the analog wiring

- Twisted or shielded wiring is not required.

Installation Spacing:

The ADT-HRSI detector is rated for installation at up to 70ft

(21.3m) spacing. These detectors may be installed in rooms

with an ambient temperature of up to 100°F (38°C).

Status LEDs:

Twin LEDs are visible from any direction. A flashing GREEN

LED shows normal system polling from the loop controller. A

flashing RED LED means the detector is in alarm state. Both

LEDs on steady shows alarm state - stand- alone mode.

Normal green LED activity is not distracting to building

occupants, but can be quickly spotted by a maintenance

technician.

Quality and Reliability:

Honeywell detectors are manufactured to strict international

ISO 9001 standards. All electronics utilize surface mount

technology (SMT) for smaller size and greater immunity to

RF noise. A conformal coating is used for humidity and

corrosion resistance. All critical contacts are gold plated.

Electronic Addressing:

The loop controller electronically addresses each detector,

saving valuable time during system commissioning. Setting

complicated switches or dials is not required. Each detector

has its own unique serial number stored in its "on-board

memory". The loop controller identifies each device on the

circuit and assigns a "soft" address to that device's serial

number. If desired, detectors can be addressed using the

SIGA-PRO Signature Program/ Service Tool.

Installation:

Signature series detectors mount to North American 1-gang

boxes, 3-1/2 in or 4 in octagonal boxes and to 4 in square

electrical boxes 1-1/2 in (38 mm) deep. They also mount to

European BESA and 1-gang boxes with 60.3 mm fixing

centers.

Honeywell recommends that this detector be installed

according to local fire alarm codes.

NOTE:

- This detector will not operate without electrical power. As

fires frequently cause power interruption, we suggest you

discuss further safeguards with your fire protection

specialist.

- This detector will NOT sense fires that start in areas where

heat cannot reach the detector. Heat from fires in walls,

roofs, or on the opposite side of closed doors may not

reach the detector to alarm it.

- The heat sensor in this device only provides a source of

information to supplement the information provided by the

ionization and photoelectric smoke sensors. The heat

sensor by itself does NOT provide life safety protection.

Under no circumstances should heat detectors be relied

upon as the sole means of fire protection.

Testing and Maintenance:

Each detector automatically identifies when it is defective and

the user friendly maintenance program shows the current

state of each detector and other pertinent messages. Single

detectors may be turned off temporarily, from the control

panel. Availability of maintenance features is dependent on

the fire alarm system used.

Scheduled maintenance should be planned to meet local

codes.

ADT-HRSI INTELLIGENT HEAT DETECTOR

Accessories:

All detector mounting bases have wiring terminals that are

accessible from the "room-side" after mounting the base to

the electrical box. The bases mount to North American 1-

gang boxes and to 3-1/2 in or 4 in octagon boxes, 1-1/2 in

(38 mm) deep. They also mount to European BESA and

1-gang boxes with 60.3 mm fixing centers.

Removing a detector from its base (except isolator base)

does not affect other devices operating on the same circuit.

Standard Base SIGA-SB:

This is the basic mounting base for Honeywell Signature

Series detectors. The SIGA-LED Remote LED is supported

by the Standard Base.

Relay Base ADT-RB:

This base includes a relay. Normally open or closed

operation is selected during installation. The dry contact is

rated for 1 amp (pilot duty) at 30 Vdc. The relay's position is

supervised to avoid accidentally jarring it out of position. The

relay base does not support the SIGA-LED Remote LED.

The relay is controlled by the detector and operates as

follows: at system power-up or reset, the relay is de-

energized.

When a detector is installed in the base with the power on,

the relay energizes for 4 seconds, then de-energizes. when a

detector is removed from a base with the power on, the relay

is de-energized. When the detector enters the alarm state,

the relay is energized.

Isolator Base ADT-IB, ADT-IBS:

This base includes a built-in line fault isolator. A detector

must be installed for it to operate. The integral isolator relay

is controlled by the detector or the loop controller. A

maximum of 96 isolator bases can be installed on one

circuit. The isolator base does not support the SIGA-LED

Remote LED.

The isolator operates as follows: a short on the line causes

all isolators to open within 23 msec. at 10 msec intervals,

beginning nearest the loop controller, the isolators close to

provide the next isolator down the line with power. When the

isolator next to the short closes, it reopens within 10 msec.

In Class A operation, the process repeats beginning on the

other side of the loop controller.

Remote LED SIGA-LED:

The remote LED connects to the SIGA-SB Standard Base

only. It features a North American size 1-gang plastic

faceplate with a white finish and red alarm LED.

SIGA-TS Trim Skirt:

Supplied with 4 in bases, it can also be ordered separately to

use with the other bases to help hide surface

imperfections not covered by the smaller bases.

Application:

Table 1 below shows six standard test fires used to rate the

sensitivity of smoke and heat detectors. The table indicates

that no single sensing element is suited for all test fires.
