GST-DC-9101(IS) Intrinsically Safe Conventional Combination Heat Photoelectric Smoke Detector
Model No :
Part Code :
DC-9101(IS)

Overview

DC-9101 (IS) Intrinsically Safe Conventional Combination Heat Photoelectric Smoke Detector is a kind of combination detector consisting of smoke sensing parts and semi-conductor heat sensing parts. It’s applicable to Zone 1 and Zone 2 of areas with explosion-proof requirement in petroleum and chemical industries. By combination of smoke detection and heat detection, it overcomes the non-sensitivity to dark smoke particles of ordinary scattering photoelectric detectors. It can also pick up fire with obvious rise of temperature such as alcohol flame, thus extending the application range
