S300 Conventional Thermal Detector

5351TE thermal detector by System Sensor forms part of the Series 300 range of conventional detectors.


5351TE thermal detector by System Sensor 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 5351TE thermal detector incorporates an Application Specific Integrated Circuit (ASIC). Combined with the latest in thermal element technology the detector provides efficient and accurate detection of fires, especially in environments such as boiler houses or kitchens where smoke detectors are inappropriate due to the high level of airborne contamination. The 5351TE 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 5351TE 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. The remote hand-held programming unit can also be used in conjunction with the Series 300 range of detectors to gain access to other advanced features. The features available include: read/write last maintenance date, read value of thermal element and perform an alarm test. Each unit can be given a unique address that will be displayed on the S300ZDU whenever the detector is in alarm.
