Specification Smart RF Module – Installing and Learning In


This Smart RF Module is designed to be installed in a Smart RF compatible smoke/heat alarm or Smart RF compatible Carbon Monoxide alarm which offers an additional option for wireless connectivity (and which is not already wireless enabled). For the current range of Smart RF compatible products see here.

When the Smart RF Module is fitted into a Smart RF compatible FireAngel Safety Technology Limited smoke/heat alarm or carbon monoxide alarm it enables the unit to be wirelessly interlinked with other Smart RF 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 Smart RF Module in order to then wirelessly interconnect the product with other alarms in the network.

When handling Smart RF Modules, please read manuals carefully before proceeding, and pay particular attention to the ESD handling guidelines.


When you are ready to install the Smart RF 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 Smart RF products.


Follow our step-by-step video or the below steps:

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

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

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 Smart RF alarm. Ideally, each unit should have three or more units within 35m of its location.
