The modern design of the ionisation chamber allows to reliably evaluate the characteristics of fire. The dual chamber principle with measurement and reference chamber ensures the automatic compensation of environmental impact. The response sensitivity of the detector can be adjusted in 5 steps, via the fire detection control panel. The proven ADM loop technology with Apollo/Discovery protocol establishes a permanent communication between the fire detection control panel and the detector. That ensures a periodical function testing of the detector. In the control panel all types of fires are detected by continuously comparing fire patterns. The influence of contamination of the measurement system is compensated for by using intelligent evaluation algorithms. With that, the response sensitivity of the detector is kept constant for a long time - a further effective step to avoid false alarms. The two LEDs with 360° visibility indicate the activated condition of the detector. The detector address is selected by means of a code card in the detector base. Therefore the detector can be changed without additional tools. The detector can be attached to various bases and it can be protected against theft. VdS Building Safety.
