KET-SHD-160 Addressable Somke and Heat Detector

KET-SHD-160 Intelligent Heat and Photoelectric Smoke Combined Detector  is consisted of smoke sensing and semi-conductor temperature sensing parts in processing and circuitry. The detector has the advantages of both photoelectric smoke detector and rate of rise and fixed temperature heat detector. Just because of the combination technology of smoke detector and heat detector, it can detect and alarm the combustion of SH3 (polyurethane plastic fire) and SH4 (n-heptane fire) in the national standard test. It can also pick up fire with obvious rise of temperature such as alcohol fire, thus extending the application range. With novel structure and attractive appearance, the detector has stable and reliable performance and high damp-proof ability. It is suitable for restaurants, hotels, libraries, office buildings, school buildings, warehouses, power rooms, etc. Features 1. The detector can be addressed in field by using Hand Held Programmer, easy and reliable for commissioning. 2. Single chip uses real-time sampling and data processing system. 3. Temperature and humidity drift compensation, dust accumulation degree and fault detection function. 4. Self-diagnostic function. 5. Non-polarized signal 2-wire. 6.LPCB CERTIFIED Technical Specifications 1.
