INTRODUCTION

This wireless module is designed to be installed in a Wi-Safe 2 

 

compatible smoke/heat alarm or Wi-Safe 2 compatible Carbon 

 

Monoxide alarm which offers an additional option for wireless 

 

connectivity (and which is not already wireless enabled). For the current 

range of Wi-Safe 2 compatible products see www.fireangeltech.com
When  the  wireless  module  is  fitted  into  a  Wi-safe  2  compatible 

FireAngel Safety Technology Limited smoke/heat alarm or carbon 
monoxide alarm it enables the unit to be wirelessly interlinked with 
other Wi-Safe 2 enabled products.

When any of the interlinked products are triggered by smoke/heat 
(or carbon monoxide in the case of CO alarms), that unit will transmit 
messages to the other units in the network, sounding all the alarms 
in the system simultaneously, which means they provide the earliest 

warning of fire, to the maximum number of people. Any number of units 
from two, up to fifty alarms can be interlinked into a single network.

NOTE: 

You will need the User Manual of the product into which you are 

installing the wireless module in order to then wirelessly interconnect 
the product with other alarms in the network. If this is not available 
please contact Technical Support on 0330 094 5830 or download from 

www.fireangeltech.com

Please read these fitting instructions carefully before proceeding, 

paying particular attention to the ESD handling guidelines below.

HOW TO INSTALL A WI-SAFE 2 

WIRELESS MODULE (W2-MODULE)

When you’re ready to install the wireless module into the compatible 
alarm, ensure you observe ESD handling guidelines.

• 

Remove the label which covers the module aperture at the back 
of the unit.

Avoid carpeted areas in cool, dry areas if possible, and reduce
static electricity if necessary by touching a grounded metal object.

• 

Carefully remove the module from its packaging, handling
the module only by the protective plastic cover, to avoid
electrostatic discharge.

• 

Be careful not to touch the components or connector pins.

• 

Carefully plug the module into the aperture in the unit as shown, 

pushing down until it lies flat within the base of the unit.

The unit is now ready to be “learned – in” (interlinked) to additional 
Wi-Safe 2 products.

“LEARNING IN” (INTERLINKING) 

YOUR WI-SAFE 2 UNITS

The process below describes ‘learning in’ two Wi-Safe 2 alarms into a 
network, “Alarm 1” and “Alarm 2”. Alarm 2 will be the unit into which 
you have installed the Wireless Module.

It is recommended that you read through these instructions prior 

to starting the process.

Alarm 1: Before starting, refer to the product’s User Manual to ensure 
the alarm is activated and ready to be learned in, with its mounting 
plate (if appropriate) attached. Please test the unit once after mounting 
to baseplate.

Alarm 2: Using a pen, a very small screwdriver or paper clip that has 

been opened out, briefly push and release the learn button located in 

a small hole in the wireless module.   

The red LED next to the learn in button will flash briefly then light up 
for approximately five seconds to show that it is ready to receive the 
“learn  in”  signal.  During  the  next  5  seconds  you  will  need  to  briefly 

press the test button on Alarm 1 to wirelessly interlink the two alarms.

Alarm 1: Will give an audible sound consisting of 2 cycles of 3 
loud beeps.

Alarm  2:  The  red  LED  on  the  wireless  module  of  alarm  2  will  flash  to 

indicate that it has been “learned-in” successfully.

Note:

 If the test button is not pressed quickly enough (before the red 

LED on the wireless module of Alarm 2 has extinguished), the learn-in 
process will fail. If this happens, repeat the “learn-in” process again, 
as described above.

Additional products should be “learned-in” in the same way. When 
learning in additional alarms, any alarm already in the network, can be 
used as ‘Alarm 1’. This means that you can “learn-in” the additional 
alarm into any unit already in the network. It will then become part of 
the whole network.

Note: 

You do not need to “learn in” the additional alarm into each 

alarm in the network.

After completing the “learn-in” procedure, test the alarms as described 
in “alarm test” in the product’s user manual.

If any interlinked alarm fails to respond to the “alarm test”, repeat 
the learning in process. If the product continues to fail to operate 
correctly, please contact Technical Support on 0330 094 5830 or 

email [email protected]

For information about where to position the alarm, and operational 
guidelines, please see the User Manual for the host product.

TROUBLESHOOTING

Problem

Solution (Alarm with W2 Module)

Your alarm does not 
sound during testing.

• Check positioning. The wireless signal might be blocked or out of range.

• If you are in the process of learning in the alarm and it does not test – repeat the process.

• If the alarm still fails to self test, please contact Technical Support (see below).

Your smoke alarm 
activates when no 
smoke is visible.

If the alarm is sounding but the red LED is only flashing once every 45 seconds, this indicates 

that an interlinked alarm has initiated alarm. Vacate the property if there is a fire hazard.

Your alarm chirps 
intermittently.

• If your alarm is chirping once every 4 hours, it is indicating that another alarm in the network has 

entered a low power pack condition. Locate the alarm with the low battery condition and replace 
the alarm as soon as possible and in any event within 30 days.

Other interlinked units 
fail to silence when one 
unit is silenced.

Interlinked units that have sensed a hazard can’t be silenced. If one or more unit remains in 

alarm, all other interlinked units will emit their audible warning again within 4 minutes. Vacate the 

property if there is a fire hazard.

You experience frequent 
unwanted alarms.

• Any activated alarm will cause other interlinked alarms to sound. Carry out these checks on the 

activated alarms in particular (red LED flashing rapidly during alarm).

The amber LED is 

flashing and the alarm 

is making a “chirping” 
sound.

If the amber LED is double flashing and the alarm is making a “chirping” sound, this indicates 

that the wireless module has a low power pack condition, or is faulty. The W2 Module should be 
replaced as soon as possible.

If the alarm fails to 
operate correctly, 
the advice of the 
manufacturer should be 
sought.

• If you have any questions about the operation of your alarm, please contact Technical Support 

between 9am - 5pm Monday – Friday. Telephone: 0330 094 5830.

Note:

 The wireless range of the module is over 200 metres in clear air/

clear line of sight. Always ensure that after any building work or after 
repositioning large items of furniture (beds, sofas, shelving units etc.), 
you carry out an alarm test on all networked alarms to ensure they are 
all still communicating. It is recommended not to exceed 35m as the 
maximum distance between any interlinked Wi-Safe 2 alarm. Ideally, 
each unit should have three or more units within 35m of its location. RF 
range can be reduced by walls, and other obstructions in the building. 
The distance between units should be reduced if obstructions may 
interfere with RF range.

Unlearning your Wi-Safe 2 Unit:

To remove an alarm from a network, push and release, then push and 
hold the learn button. When the red LED goes out, release the button. 

Once the LED has flashed 5 times you have successfully ‘Unlearned’ 

the alarm.

When removing an alarm / module from any Wi-Safe 2 network it is 
generally good practice to “unlearn” every alarm/module (in the same 
way as mentioned before) and rebuild the network once again by 
following the “learning-in” process.

NOTE:

 It is important not to rush the Wi-Safe 2 system and is also 

good practice to allow several minutes after un-learning the system 
before rebuilding the network once again.
