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.
