DSS-PC series

AA Detector Base Sounder Strobe


The DSS-PC-I00 AA Detector Base Sounder + Strobe is a loop-powered audible and visual alarm device that plugs in to System Sensor analogue addressable detector bases such as the B501AP. The built-in detector base accepts a System Sensor analogue addressable detector.

Each DSS-PC-I00 can be individually activated (addressed) by a fire panel over an analogue addressable loop.

Two audible alarm tones can be controlled by the fire panel. These tones indicate alarm Stage 1 (Evacuate) and alarm Stage 2 (Alert). The pair of tones may be configured from any one of 32 optional two-stage tone-sets.

The DSS-PC-I00 is compatible with the optional anti-tamper feature on the B501AP and compatible detector bases. When activated, the anti-tamper feature inhibits unauthorised removal of the alarm device.

The B501AP base has a continuity spring which allows field wiring continuity to be checked without the device plugged in.

The DSS-PC-I00 is independently certified to AS ISO 7240.3:2014 and AS ISO 7240.23:2014 (Class O).
