The 2351TEM photoelectric smoke/thermal 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 it’s multitude of innovative features, the Series
300 is a detector which ‘acts conventionally, thinks intelligently’.
The 2351TEM photoelectric smoke/thermal detector incorporates an optical chamber and a thermal element,
which in turn are continually monitored by an on board processor by using algorithms developed specifically for the
unit. An alarm signal is only enabled in the detector once the processor is satisfied that an incipient fire has been
detected. By using a combination of inputs, the incidence of nuisance alarms is reduced while at the same time,
the response time to an actual fire is also improved.
The 2351TEM 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.
The 2351TEM detector incorporates a bi-colour LED indicator. The integral LED changes colour according to the
detector’s status - Green = Normal, Red = Alarm. This benefits the user by providing clear, instant visual indication
of the detector’s condition. The Green LED can be programmed for blink/no blink operation.
