Description :

The S2351E photoelectric smoke detector forms part of the Series 300 range of conventional detectors. This range of detectors has been produced using the latest in manufacturing and design techniques, pushing out the boundaries of existing conventional detector technology. With its multitude of innovative features, the
Series 300 is a detector which ‘acts conventionally, thinks intelligently’.

The S2351E photoelectric detector incorporates an Application Specific Integrated Circuit (ASIC). Combined with the latest state-of-the-art optical chamber the detector provides efficient and accurate detection of fires with a high level of resilience to non-fire environmental influences.

The S2351E and other detectors in the Series 300 range are backward compatible with the Series 100 detector bases, thus providing the capability to upgrade, extend and maintain existing Series 100 installations.
