1.Composite smoke-sensing and temperature-sensing 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.

2.Built-in standalone CPU, quick calculating speed and excellent stability.

3.Non-polarity two-wire bus to make cabling easy, and avoid wrong wiring.

4.It adopts backward scattering maze and makes it more sensitive to detect the smoke generated from burning of different materials.

5.Sealed robber type of heat sensitivity component enhances anti-humidity and anti-erosion.

6.Three sensitivity levels of the detector are optional at the control panel to suit different environments.

7.Drift compensation to reduce nuisance alarms.

8.Temperature rising compensation to improve responsive capacity upon different temperature rising status.

9.Support sensor fault inspecting and reporting to ensure system work and maintain well.

10.Special production process to make the device work at high temperature, high humidity and high altitude environment.

11.ESD static protection grade 12000V, strong anti-interference ability.
