BS-655/MAR is a conventional optical smoke detector which is produced in accordance with EN 54-7, IEC 60092-504, IEC 60533 and co-operates with conventional fire alarm panels.
The detector has two parts, one plastic base which is similar to all Olympia Electronics detectors and the main body/part of detector. The base is mounted on the ceiling and the main part adjusts on the base with a simple rotation.
The detector has also an indication LED which is visible from 360˚ view and flashes every 4sec to indicate good operation (resting state). In case of fire detection the indication LED lights continuously until there is a reset signal from the panel. The indication LED lights even when we silence the sirens, in order to show us the detector that issued the alarm.
