When the contact relay closes due to the host panel going into alarm, the AR1 remote repeater is simultaneously triggered and a sounder activates and an LED illuminates. The sounder can be silenced by pressing a mute button, but the light remains on until the alarm has been cleared. If fitted with a relay, it is possible to link to another AR1 repeater panel or to the BMS.
Typical applications include computer rooms, comms rooms, server rooms, data centres and plant rooms.
