POSITIONING
This Alarm Control Unit is suitable for use in domestic premises only. It should be installed at an
accessible point on the wall, in a location where it will not be accidentally operated or knocked.
INSTALLATION
• Ensure this Alarm Control Unit is installed by a competent person who feels able to install it
according to the instructions.
• Read all installation instructions prior to installing this product.
WARNING: To prevent injury, this Alarm Control Unit must be securely attached to the wall in
accordance with the installation instructions.
To mount the bracket onto a wall:
Please ensure that you use the screws provided, as they were chosen specifically for use with this
product. Drill holes into the wall and insert supplied wall plugs. Screw the bracket in place.

ACTIVATING THE ALARM CONTROL UNIT
The Alarm Control Unit has a sealed-in non-
replaceable battery. To activate the control unit
remove the disabling tab.
Upon activating the control unit all three LED's
should simultaneously flash twice, to indicate
that they are working.
Once the alarm is activated it can then be learnt
into a Wi-Safe 2 network, before securing to the
wall bracket.

8
WIRELESS INTERLINK
The Alarm Control Unit is designed to be used as a remote interface on a network of up to 49 products
within the Wi-Safe 2 range. The Alarm Control Unit can be used to test, silence or locate any alarms
on the Wi-Safe 2 network. It is not designed to communicate with wireless alarms from other ranges
or manufacturers. The control unit needs to be ‘learned-in’ or interlinked, in order to communicate
within the network.
Wi-Safe2 enables wireless communication with any other product with Wi-Safe2 technology inside.
When one alarm detects smoke / heat / carbon monoxide, the wireless module inside sends a signal
to all the connected alarms, ensuring almost instantaneous reaction across the network.

HOW TO ‘LEARN-IN’ THE ALARM CONTROL
UNIT TO A WI-SAFE 2 NETWORK:
1. Using a ballpoint pen, briefly push and
release the 'learn button' on the back of the
control unit. The red LED next to the learn
button will flash briefly then light up for
approximately 5 seconds.
2. During these 5 seconds you need to briefly
press the test button on an alarm already in
the network, to wirelessly interlink the two.
The alarm will sound its audible test pattern.
3. The red LED on the back of the control
unit will flash to indicate that it has been
‘learned-in’ successfully. If the test button
is not pressed quickly enough, the ‘learn-
in’ process will fail. If this happens, repeat
the process.
Your Alarm Control Unit counts as one unit within
the network. If it is installed retrospectively, then
the existing network cannot exceed 49 units in
size.

10
4. To complete the installation simply slide the
control unit onto the bracket.The control unit
is now part of the whole network.
The method above assumes you have already
installed your alarm network, prior to installing
your Alarm Control Unit. If you want to install
your Alarm Control Unit first, you can learn your
smoke, heat and CO alarm into it by following
the instructions in your alarm manual, using the
Alarm Control Unit as alarm 1.
MAKING THE ALARM
CONTROL UNIT TAMPER
PROOF
Do not complete this action until you have
wirelessly interlinked all of your alarms.

11
The Alarm Control Unit is provided with an
anti-tamper feature, ensuring, where needed it
cannot be removed from the wall.
To make use of this feature you will need to push
out the two blanking plates on the top right-hand
side of the bracket, using a small screwdriver,
being careful to support the bracket fully whilst
doing so.
Once the rest of the installation is complete, and
the control unit is fixed to the bracket it can only
be removed using the following method:
Insert a small screwdriver into the hole on the
top right-hand corner of the control unit, until it
stops, this will disengage the lock, then gently
ease the control unit up to release it from the
bracket.

12
TESTING THE ALARM
SYSTEM
Press the Test / Silence ( ) button to
confirm that the control unit is operating
properly. This will instigate a three minute test.
All networked alarms should sound. To stop the
test (earlier than 3 minutes), simply press the
Test / Silence ( ) button again. This test
should be performed on a weekly basis.
Pressing the Test button on the Alarm Control
Unit creates a lot of RF traffic. If you need to use
the feature more than once, please wait for 5
minutes to let the network settle down.

PRODUCT FUNCTIONALITY
Function Description
Test / Silence button
Test button:
This allows you to test all wirelessly interlinked alarms from one
centralised location.
Silence button:
This will silence all wirelessly interlinked smoke and heat alarms and
reduce the system sensitivity for up to 10 minutes.
Locate button
In an alarm event this will silence all wirelessly interlinked alarms
except the initiating alarm which has sensed carbon monoxide / smoke.
Smoke / heat alarm indicator This indicates that a smoke / heat alarm has been activated.
Carbon monoxide indicator This indicates that a carbon monoxide alarm has been activated.
Fault indicator
This indicates a fault with the control unit or one of the alarms within
the network.

14
LOCATE BUTTON
If the alarms are sounding and an alarm indicator is flashing, but there's no obvious hazard, pressing
the 'Locate' button ( ) will silence all wirelessly interlinked alarms except for the initiating alarm
which has sensed smoke / heat or carbon monoxide. Within two minutes the system will return to
normal operation and the alarms will continue to sound if smoke / heat or carbon monoxide is still
present. To make locating the alarm easier, the control unit can be removed from its bracket and
carried around the property (providing the tamper proof function has not been engaged), allowing
you to press the 'Locate' or 'Test' button whilst moving from room to room.
SILENCE BUTTON
If the alarms are sounding and the smoke / heat alarm indicator is flashing, but there's no obvious
hazard, pressing the 'Silence' button ( ) will silence all wirelessly interlinked alarms and reduce the
system sensitivity for up to 10 minutes. However if excessive smoke is sensed the silence function
will be overridden. The indicator will continue to flash unless the smoke disappears. Please Note:
An alarm cannot be silenced using the Alarm Control Unit if carbon monoxide has been detected,
however the 'Locate' function will allow you to find out which of the CO alarms is the initiating alarm.
ALARM MEMORY
If one of the alarm indicators is flashing every 10 seconds this indicates that a smoke alarm,
heat alarm or carbon monoxide alarm has previously been activated. Pressing the 'Locate'
button ( ) will clear the LEDs and sound the source alarm so you can investigate this further. You

15
can press the 'Locate' button ( ) repeatedly until the source alarm is identified (fully compatible
with the FireAngel Specification Wi-Safe 2 smoke, heat and CO alarms). Please Note: Only the most
recent alarm event will be visible. If both a CO and smoke / heat alarm have previously been activated,
both LED's will show but the CO alarm will always take precedence, and this is the alarm which will
sound. Never ignore an alarm. If there is evidence of an alarm event, be sure to investigate further.
FAULT DETECTION
If the amber fault LED and a red alarm LED are flashing this indicates that an alarm on the network
has developed a fault. To identify the faulty alarm press the 'Locate' button. If the alarm in fault
sounds a unique ‘SOS’ sound pattern continue to 'A' below. If no SOS sound pattern is heard proceed
to 'B' below.
A. In case you need to locate the unit again, please wait for 2 minutes before trying to locate for the
SOS pattern. Take down the alarm which is sounding. Unlearn the alarm from the network using
a ball point pen in the circular 'learn-in' hole in the back of the alarm. Briefly push and release and
then push and hold the 'learn-in' button. The red LED will remain illuminated during this process.
When the red LED goes out, release the button, it will then flash twice, followed by three further flashes
to illustrate that the alarm has successfully been 'un-learnt' from the network. Reorganise the network as
detailed on the next page. The LEDs indicating a fault should now have stopped flashing and the faulty
alarm can now be replaced with a new alarm if required.

16
B. Check all alarms are on their base plate and activated. If all alarms are activated, clear the fault by
pressing the locate button twice.
REORGANISING A NETWORK
If you have un-learnt and replaced or removed any alarms, you can 'reorganise' in order to optimise
the network performance.To do this you will need to press and hold the 'Locate' button for 5 seconds.
The Alarm Control Unit will then enter 'Reorganisation Mode', during which time you will see a series
of flashes from the LEDs. The time taken for this process to complete will depend on the number of
units in the network.
If successful, once the reorganisation is complete, the Control Unit should return to standby mode,
with no LEDs flashing.
If the reorganisation is not successful, and LEDs are still flashing (all 3 LED's flash together
( + + ) 3 times, then a fourth flash ( + only) occurs, repeatedly), you will need to exit
'Reorganisation Mode'.To do this hold the 'Locate' button for 5 seconds, wait for 5 minutes and then
repeat the process above.
Prior to performing network reorganisation, test the network by pressing the test button on one of the
randomly selected units and ensure that all units chirp / flash in response. This is essential to make
sure that all the units are communicating with each other and ensures network reorganisation does

17
not delete wanted units. In case one of the working units is out of range for networking, please check
the installation position of the units and adjust / install an additional unit to help with the routing of
messages.
WHEN AN ALARM SOUNDS
Never ignore an alarm.
If there is a fire evacuate the premises and call the fire brigade. If the source of the alarm is not
immediately apparent check which indicator is flashing on the control unit.
If the CO indicator is flashing:
• Keep calm and open the doors and windows to ventilate the property.
• Stop using all fuel-burning appliances and ensure, if possible, that they are
turned off.
• Evacuate the property leaving the doors and windows open.
• Ring your gas or other fuel supplier on their emergency number; keep the
number in a prominent place.
