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.
