Introduction
When the decision is taken to use self-contained respiratory protection apparatus (SCBA) in a life
threatening hazardous environment, it is essential that an effective control procedure is in place to
manage, monitor and safeguard the wearer of the equipment.
In the United Kingdom, the Technical Bulletin – Breathing Apparatus/Command and Control Procedures,
together with the Manual of Firemanship, provide guidance for Fire Authorities and Firefighters in the
introduction, application and management of a risk based approach to the wearing of breathing apparatus.
The DrägerMan PSS® Merlin® Telemetry System package further enhances and supports these control
procedures by providing a means of remote 2way digital data and alert status communication between
the wearer of the self contained respiratory protection apparatus and an external support control module.
To achieve this communication, the DrägerMan PSS® Merlin® Telemetry System modules (Entry Control
Board and Data Radio Unit) interface with the DrägerMan Sentinel Series electronic signal and warning
unit fitted to the self contained respiratory protection apparatus.
It is important to be aware that communication can be affected by a breakdown in the transmission signal
due to extremes of application scenarios such as long distance, building construction, below ground
structures etc. Dräger offer the DrägerMan Repeater, which is a system module option designed to
provide a means of enhancing the signal effectiveness in harsh environments. Contact Dräger for details.

Description and Intended Use
The Entry Control Board
The DrägerMan PSS® Merlin® Entry Control Board (ECB) is a battery-powered unit incorporating an
integral digital radio transmitter and receiver with associated antenna. The ECB has twelve channel slots
each able to accept the encoded tally of an individual Data Radio Unit. Inserting the tally activates the
transmission link monitoring capability between the ECB, the Data Radio Unit and the DrägerMan
Sentinel Series electronic signal and warning unit combination.
Entry Control Boards are individually programmed with a unique identity code (e.g. Fire Brigade Identity
Code or a User Code) together with the allocated Board Identification (ID) Number.
The data transmission link (Log On) between the Entry Control Board and each Data Radio Unit and
Sentinel combination is activated following the insertion of an encoded transponder ‘Tally Key’ into any
of the available channels of the board. The ‘Tally Key’ is encoded with the same codes as the corresponding
Data Radio Unit.
The ECB identifies the associated Data Radio Unit/Sentinel combination and the On-Line radio icon
illuminates (Green) continuously, confirming a successful radio link with the Sentinel. The individual
channel screen defaults to show the actual ‘Time of Whistle’ information.
At an incident, the use of the Entry Control Board (ECB) is normally the responsibility of an Entry
Control Officer (ECO). The ECO must ensure that agreed control procedures are in place to manage,
monitor and safeguard the wearer of the breathing apparatus.
To support any possible requirement for incident analysis information, the ECB stores and maintains an
‘Event Log’ (datalog) that can be downloaded to a computer. Contact Dräger for full details of
associated software.
For positive and secure support of the ECB at and during an incident a support bracket is available
(see order list) for fitment to a tripod unit.
Receiving Information
The On-line Signal radio icon illuminates (Green) at each channel of the ECB indicating satisfactory
radio contact with the associated Data Radio Unit and Sentinel combination.
The ‘Time of Whistle’ (TOW) default shown on the individual channel screens is calculated automatically
by the ECB by adding the initial TTW value transmitted at the initial Log On of the Sentinel, to the actual
time shown on the real time clock of the ECB.
Edition B: April 2005 5
The following additional on going data is communicated to the ECB every 20 seconds from each ‘Logged
On’ Data Radio Unit and Sentinel combination:
lTime to Whistle (TTW).
lPressure.
lTemperature of the Sentinel.
By pressing the information button of the ECB, a controller is able to scroll between the Time of
Whistle, Time to Whistle, Pressure, and Temperature. The Time to Whistle information is the default
data displayed on the Sentinel.
Additionally, the Time Elapsed from activating the Sentinel to ‘operational mode’ can be displayed.
The above information is displayed on the individual channel screens of the ECB and the defaults and
data sequence can be configured to meet the requirement of the end user. Contact Dräger for details.
Additional alert status signals received from the Data Radio Unit are:
lAutomatic Distress Signal Unit (ADSU) alarm signal – movement sensor.
lManual Distress Signal – panic button.
lVoluntary Withdrawal.
Each of these signals is differentiated and identified on the ECB by separate illuminated icons.
Transmitting Information
The ECO is able to activate the following transmissions from the Entry Control Board to each ‘Logged
On’ Data Radio Unit:
lAcknowledgement of a Voluntary Withdrawal transmission from the Data Radio Unit.
lSelective Evacuation - evacuation command to a specific Data Radio Unit or Units (team).
lEvacuation Signal – simultaneous evacuation command to all ‘Logged On’ Data Radio Unit.
lAcknowledgement of ADSU or Panic Alarm.
Manually Recorded Information
Adjacent to each of the channel screens is rectangular white panel areas. Using a waterproof marker
(e.g. China Graph Pencil), these can be used to record any relevant data regarding any individual or
defined teams, e.g. location of the wearer, location of the team, team reference etc.
If required the board can be photographed to provide any evidential requirement of an incident.

The Data Radio Unit
The DrägerMan PSS® Merlin® Data Radio Unit is a battery-powered unit incorporating an integral digital
radio transmitter and receiver with associated antenna. A cable and connector from the radio module
connects to an infrared interface to a DrägerMan Sentinel. The integrated assembly is able to transmit
data to communicate audible and visual alarm signals to the associated DrägerMan PSS® Merlin® Entry
Control Board.
The radio of the Data Radio Unit is programmed with an identification code for the unit (radio) together
with a unique identity code (e.g. Fire Brigade Identity Code or a User Code).
Supplied with each Data Radio Unit is a matching transponder ‘Tally Key’ that is encoded with the same
codes as the corresponding Data Radio Unit. A label on the ‘Tally Key’ identifies the users identification
code for the corresponding radio.
Included on the ‘Tally Key’ are markings with spaces that allow the following information to be added to
the tally using a suitable waterproof marker:
1. The name of the wearer.
2. The cylinder contents pressure on activation of the Sentinel is shown.
3. The actual ‘Time In’ to the risk area – shown on the clock of the Entry Control Board.
In the case of incidents where a possibility of radiation risk may be present, a Dosimeter reading (prior
to entry and after exit) may be recorded if necessary on the reverse side of the tally.
When the ‘Tally Key’ is inserted into any of the available channels of the Entry Control Board, the ECB
identifies the associated Data Radio Unit/Sentinel combination and the digital communication link is
activated. The ‘Green’ and ‘Red’ LEDs of the IR Link Unit on the rear of the Sentinel ‘flash’ intermittently.
A release key is available to unlock and detach the battery pack from the radio module.

In Use
An Entry Control Officer (ECO) is a competent person nominated to control and monitor an Entry
Control Board (ECB) and to direct and instruct all wearers of Breathing Apparatus (SCBA) at an
incident.
A safe and secure entry control point (ECP) for the ECB should be established from which the ECO
is able to effectively control the adopted procedures. At this point the ECB can be mounted to a tripod
to provide positive support and ease of use at an incident.
The operational control procedures adopted should be in line with the requirements defined by the user
or by national legislation in the country of use. In the case of professional users, e.g. Fire Brigades,
these guidelines are in addition to their own guidelines for command and control procedures.
The following instructions cover the basic operational procedures and the In Use functional features of
the DrägerMan PSS® Merlin® Telemetry System.
Pre – Entry Procedure
The Data Radio Unit - SCBA
lHaving put on the SCBA and carried out all
functional checks as described in the User
Instructions for the apparatus, the Wearer
should activate the Sentinel to ‘operational
mode’. The ‘Green’ LED on the front of the
Sentinel flashes at one-second intervals and
the ‘Red’ LED on IR Link cover also flashes.
The wearer is now available for entry to the
risk area.
Note: When the Sentinel is activated to operational mode, this ‘Wakes Up’ the radio of the Data Radio
Unit into ‘stand by mode’ waiting for a signal from the entry control board, i.e. Log On request .
1448USA
Edition B: April 2005

The Entry Control Board - Making Contact
lWith the Sentinel activated in ‘operational mode’ the wearer of the SCBA must pass the encoded
‘Tally Key’ to the ECO with the following information written on the tally using a suitable waterproof
marker;
1. The name of the wearer.
2. The cylinder contents pressure – shown on the Sentinel.
If necessary, the ECO can check that the radio identification number on the label of the tally
corresponds to the radio identification number on the label of the data radio module. Using a
suitable waterproof marker, the ECO can then write and record the following remaining data onto
the tally;
3. The actual ‘Time In’ to the risk area – shown on the clock of the Entry Control Board.
Note: In the case of incidents where a possibility of radiation risk may be present, a Dosimeter reading
(prior to entry and after exit) may be recorded on the reverse side of the tally.
lThe ECO fully inserts the ‘Tally Key’ into an available channel slot. The following rapid automatic
activation and transmission sequence starts;
1. The ECB immediately ‘Wakes Up’. A double sharp ‘Bleep’ sounds.
Note: The double sharp ‘Bleep’ sounds only when the first tally is inserted.
2. A sensor in the selected channel reads and verifies the code in the transponder of the tally.
3. The radio in the ECB transmits a signal to the same coded Data Radio Unit requesting
to ‘Log On’ the unit onto the ECB.
4. The Data Radio Unit transmits an acknowledgement signal to the ECB.
5. The ECB receives the ‘Log On’ acknowledgement – the data exchange starts.
6. The initial TTW value transmitted from the Sentinel is added to the actual time shown on
the real time clock to determine the ‘Time of Whistle’ (TOW).
7. The ECB starts the ‘Time Elapsed’ count (minutes).
Note: If the ECB is defaulted to show TTW, the ECO should observe the time to whistle (TTW) reading
of the associated Sentinel display and add this time (minutes) to the ‘Time In’ to establish an estimated
‘Time of Whistle’ (TOW). Using a suitable waterproof marker, the estimated ‘Time of Whistle’ should be
recorded in the rectangular white area on the control board adjacent to the selected channel slot in the
ECB or over the tally area.
Edition B: April 2005 19
Note: An intermittent short ‘flash’ Off of the Red LED signals a low charge condition
of the radio battery. Fit a fully charged battery.
lDuring the ‘Log On ‘ sequence the following
visual changes take place on the ECB and the
Sentinel:
1. The channel screen momentarily displays
the data radio identification number,
followed by the time count display (E :00),
then changes to the default - ‘Time of
Whistle’ (TOW).
Note: The time to whistle (TTW) value is shown in
the display of the Sentinel.
2. The On-Line data radio icon
illuminates ‘Green’ continuously,
confirming a successful radio link with
the Sentinel.
Important Note: If the channel screen momentarily
shows a Fault Code ‘Et’ then changes to E :00
display, the ‘Log On’ has been unsuccessful and
initially indicates a defective transponder in the tally.
Refer to the next section - Making Contact – Manual.
3. The date display changes to show a series
of ‘dash/dot’ elements that provide an
indication of the charge condition of the
batteries.
e.g. eight elements indicate 100%
charge.
4. The ‘Green’ and ‘Red’ LED’s of the IR
Link Unit on the rear of the Sentinel ‘flash’
alternately confirming:
la successful radio link with the ECB - flashing
‘Green’.
la satisfactory charge condition of the Data
Radio Unit battery - flashing ‘Red’.

If there is a loss of radio contact between the radio
of the ECB and the Data Radio Unit then the On-
line radio icon of the affected channel of the
ECB will begin to flash. The ‘Green’ LED at the
rear of the associated Sentinel will stop flashing
and the ‘lost’ communication icon will be displayed
on the Sentinel accompanied by an audible ‘bleep’
tone. During the communication failure the ‘lost’
communication icon will be displayed alternating
with the clock (operation) icon - as shown. If at
any time radio contact is re-established then the
On-line radio icon of the ECB will illuminate ‘Green’
continuously and the ‘Green’ LED of the Sentinel
will begin flashing and the ‘lost’ communication
icon will be cancelled. The associated channel
screen data will be updated at the next data signal
transmission from the Sentinel.
Loss of Radio Contact (ECB to PU)
1906
During loss of radio contact the following should be noted:
lThe On-line radio icon of the affected channel of the ECB will continue to flash.
lThe ‘Green’ LED at the rear of the associated Bodyguard will stop flashing and the ‘lost’
communication icon will be displayed.
lThe associated channel screen will no longer show the result of the dynamic data transmitted from
the Sentinel. Data will change against real time as follows;
TTW - If ECB is programmed at Time to Whistle (TTW) the data screen time will count down at
one-minute intervals from the time shown at the point of loss of radio contact.
TOW - If ECB is programmed at Time of Whistle (TOW) the data screen time will remain at the time
shown at the point of loss of radio contact.
Important Safety Note: In the case of possible permanent loss of radio contact then the ECO and the
wearer of the Sentinel must take appropriate actions in line with established user guidelines and control
procedures.
Edition B: April 2005 31
After Use
All wearers of breathing apparatus that are Logged On to an ECB must return to the Entry Control Point
(ECP) to ensure that the Log Off procedures are followed. The procedures must be carried out under
the supervision and control of the Entry Control Officer (ECO).
Log Off Procedure
lThe compressed air breathing apparatus is to be shut down by the wearer as described in the After
Use section of the User Instructions supplied with the equipment, i.e. remove facepiece, close
cylinder valve, vent the system of pressure. The display of the Sentinel will show ‘0’ PSI and ‘0’
TTW. The ECB will emit two short audible ‘Bleeps’ and the associated channel screen of the ECB
will ‘flash’ the Time of Whistle data that will now correspond to the time shown on the Time Clock.
Note: The Sentinel will remain in ‘operating mode’ until it is switched ‘Off’ (deactivated).
lAt the ECB the ECO will identify the wearer then remove the tally from the associated channel and
hand it over to the wearer. On removing the tally, and after up to 20 seconds the channel screen
will begin to alternate between displaying the data radio identification number and the Time of
Whistle data.
lThe wearer should switch ‘Off’ the Sentinel. A Log Off signal will be transmitted from the Data
Radio Unit to the ECB. After up to 20 seconds the channel screen will switch ‘Off’ and the
associated Data Radio Unit will return to ‘Sleep Mode’ - ensure all IR link LED’s are ‘Off’.
lRepeat the above procedure for all Logged On units. The ECB will not return to ‘Sleep Mode’ until
all other Data Radio Units have been Logged Off.
Important Note: If during an incident a permanent breakdown in communication has occurred between
the ECB and a ‘Logged On’ Data Radio Unit, it will be necessary to initiate a Force Log Off procedure.
See section ‘Forced Log Off Procedure’.
Edition B: April 2005

lRemove the tally – press the key the
main screen changes to the selected channel,
e.g. ‘CHAN04 N’ with the ‘No’ symbol
‘flashing’. Using the or keys of
the keypad toggle between the ‘Yes’ and ‘No’
symbol. When ‘CHAN04 Y’ is displayed
again press the key, the display will
change to ‘LOGOFF’. Repeat the procedure
for any further Data Radio Units requiring a
Forced Log Off.
lCheck the Channel number to be Logged Off and then enter the number by either:
1. pressing the appropriate numeric keys of the keypad. The numeric characters will stop
‘flashing’ and will change from the right as the number(s) is entered.
or
2. pressing the evacuation button of the appropriate channel. The channel number will be
entered automatically on the display.
lPress and then release the key of the
keypad. The display changes to show ‘QUIT’
status.

lRepeatedly press the or keys of
the keypad to scroll the display until ‘LOGOFF’
is displayed and then press the key.
The main display will change to show ‘CHAN
00’ with the numeric characters ‘flashing’.
Forced Log Off Procedure
A breakdown in communication between the ECB and a Logged On Data Radio Unit will cause the
illuminated ‘Green’ On-Line radio icon of the associated channel to begin to ‘flash’. The channel screen
will display the last value transmitted before failure of the signal. This may only be a temporary
communication failure due to the wearer becoming out of range of the ECB. When the date radio unit
comes back in range, the On-Line radio icon will return to illuminate continuously, confirming that the
radio link has been re-established. If however the breakdown in communication is permanent, it will be
necessary on the return of the wearer to the Entry Control Point for the ECO to initiate the following Force
Log Off procedure. This procedure is necessary to return the ECB to ‘Sleep Mode’.
