The Analogue Addressable Smoke Detector (2251BPI) is a plug-in photoelectric smoke detector with analogue addressable communication.
The smoke level in the sensor chamber is monitored continuously and reported to the fire panel. The alarm threshold for each individual 2251BPI detector is programmable in the fire panel configuration software.
The detector’s address on the analogue addressable loop is easily set using rotary address switches. A suitably configured fire panel will identify the location of any detector which has triggered an alarm, defect or maintenance signal.
