KET-HD-140 Addressable heat detecter

KET-HD-140 Addressable Rate of Rise and Fixed Temperature Heat Detector (Detector) uses advanced SCM technology. According to a variety of advanced fire criterion, detector can accurately and timely detect the changes of ambient temperature and determine fire and then alarm.

With novel structure and attractive appearance, convenient and reliable installation, the detector is suitable in places where may have smokeless fire, lots of dust or smoke and steam retained under normal circumstances, such as indoor garages, kitchens, boiler rooms, generator rooms, drying rooms, power generation, dehydrating workshop, etc. Features

1. Non-polarized signal 2-wire.
2. The detector can be addressed in field by using Hand-Held Encoder, easy and reliable for commissioning.
3. Thermal sensitive element improves the response speed of temperature variation.
