Conventional S300
– Photoelectric Smoke Detector

The 2351E photoelectric smoke detector forms part of the Series 300 range of conventional detectors. With its multitude of innovative features, the Series 300 is a detector which ‘acts conventionally, thinks intelligently’.

The 2351E photoelectric detector incorporates an Application Specific Integrated Circuit (ASIC). Combined with the latest state-of-the-art optical chamber – which operates on the light scattering principle – the detector provides efficient and accurate detection of fires with a high level of resilience to non-fire environmental influences.

It incorporates a bi-colour LED indicator for instant visual indication of condition: Green = Normal, Red = Alarm.
