JTF-GDM-936EAddressable multi-sensor smoke and heat detector

Key features

It comprises optical smoke and thermistor temperature sensors which give both a combined signal as well as a separate heat signal for improved false alarm management.
It adopts backward scattering maze and makes it more sensitive to detect the smoke generated from burning of different materials.

JTF-GDM-936E spot-type composite smoke-sensing and temperature-sensing fire detector (hereinafter referred to as the detector) is a multi-element composite detector constituted jointly by a smoke sensor and a semiconductor temperature sensor in respect of technological structure and circuit structure. It has not only the performance of photoelectric smoke-sensing fire detectors but also the performance of temperature-sensing fire detectors.
This detector uses a non-polarity two-wire bus system, and can be jointly used with the 9000 series alarm controllers produced by our company.
