How do I manually interlink my FireAngel One alarm network?

FireAngel One devices have two pairing modes: Primary mode, indicated by a fast-flashing red LED, and Secondary mode, indicated by a slow-flashing red LED.

To manually interlink your FireAngel One alarms:

  1. Set the first alarm to Secondary mode. Install the alarm onto its baseplate, then press the Test button three times in quick succession. The red LED will illuminate to indicate that the device is in Secondary mode.
  2. Add another alarm to the network. Ensure the second alarm is fitted to its baseplate, then press its Test button five times in quick succession. The red LED will remain illuminated while the device searches for the network.
  3. Confirm the connection. When the devices have located each other, the red LED will begin to flash. Both devices will chirp once to confirm that they have successfully interconnected.
  4. Add additional alarms. You can connect up to 20 FireAngel One devices on a single network. To add further alarms, repeat the pairing process for each device.
