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-Safe 2 enables wireless communication with any other product with Wi-Safe 2 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

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
can press the 'Locate' button ( ) repeatedly until the source alarm is identified (fully compatible
with FireAngel 230V Wi-Safe 2 smoke*, heat and CO alarms) *Not compatible with version ST-630 with W2
radio module or WST-630
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
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

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
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
16
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
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
