Description
The addressable Optical Smoke Detector AO-55000-
620 uses the scattered light principle, and was deve-
loped for the detection of smoke particles in a wide
range of fi re detection applications. The modern design
of the sensing chamber allows to reliably evaluate the
characteristics of fi re.
The proven ADM loop technology with Apollo/Discovery
protocol establishes a permanent communication bet-
ween the fi re detection control panel and the detector.
That ensures a periodical function testing of the detec-
tor. In the control panel all types of fi res are detected by
continuously comparing fi re patterns.
The infl uence of contamination of the optical measure-
ment system is compensated for by using intelligent
evaluation algorithms. With that, the response sensiti-
vity of the detector is kept constant for a long time –
a further effective step to avoid false alarms.
The activated condition of the detector is indicated by a
red LED. The detector address is selected by means of
a code card in the detector base. Therefore the detec-
tor can be changed without additional tools.
The detector can be attached to various bases and it
can be protected against theft.
