AJAX EN54 Remote indicator black: makes a concealed detector visible
The EN54 Secondary indicator repeats the alarm indication of a fire detector that is installed out of sight, so that in the event of an alarm you can see immediately which detector has been triggered.
If a detector is installed above a suspended ceiling, in a duct or in a technical room, the secondary indicator lights up in a clearly visible location. The indicator is supervised by the Ajax Fire Hub and communicates securely via Jeweller.
