They are composed by two parts. A plastic base which is placed on the ceiling and the main
body of the detector which fits on the plastic base with a simple rotation to the right. The
o
detectors have a 360 visible led and a remote led driver which are light up constantly in case
of detection of fire, till cancelled from the panel. They are turned off only when a reset
command is given from the panel. The indicator led blinks every 6 sec indicating the normal
function.
The detector has fault diagnosis and dust compensation functions, which automatically
informs you through the onboard LED when replacement or cleaning actions are required.
The indication LED blinks every 7 seconds. In normal operation it blinks 1 time, if cleaning
action is required it blinks 2 times and if there is a failure it blinks 3 times. After cleaning
procedure it will take about 10 minutes for detector’s working indication to return to normal.
