Pairing with a radio smoke detector alarm
1. Power up the relay board (receiver).
2. Hold down the conguration push button on Relay Cat. No. 0 405 14 for 5 seconds. 3 beeps conrm that the action has
been taken into account and the orange LED ashes. Relay Cat. No. 0 405 14 sends a request to an existing group
(smoke detector alarms)
3. Press the test button on one of the group's smoke detector alarms. 1 long beep conrms completion of the action.
Relay Cat. No. 0 405 14 is now paired with the smoke detector alarm and automatically switches to installation
optimisation mode.
4. Move Relay Cat. No. 0 405 14 towards its planned location and check the quality of reception of the radio signal
(see "radio link quality check" table below). Sequences of 1 to 5 beeps a few seconds apart indicate the quality of the
radio link.
5. Mount Relay Cat. No. 0 405 14 at its chosen location.
6. Press the conguration push button on Relay Cat. No. 0 405 14. 4 beeps conrm that it has left installation optimisation
mode, and 4 more beeps conrm that it has left conguration mode. The system is now operational.
- Cancelling the pairing of a smoke detector alarm:
Press for 10 seconds at stage 2 of the pairing procedure (see above). 4 long beeps conrm it has been cancelled.
- Radio link quality check
When Relay Cat. No. 0 405 14 is in installation optimisation mode, it sounds 1 to 5 beeps a few seconds apart. Check the
quality of the radio link according to the number of beeps sounded by Relay Cat. No. 0 405 14.

monoxide detector and Cat. No. 0 405 14.
- Press the test push button on the smoke detector alarm
- The test signal is sent to Relay Cat. No. 0 405 14 for 5 minutes.
- Testing all smoke detector alarms: :
This function can be used to check the quality of the radio link between all detectors paired with Relay Cat. No. 0 405 14.
- Press (briey) the push button on Relay Cat. No. 0 405 14
- The test is activated on all paired smoke detector alarms. An audible signal indicates that transmission is in progress.
Note: this function is disabled in alarm mode.
