Product Features：
- A 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.
- Built-in standalone CPU, quick calculating speed, and excellent stability.
- Non-polarity two-wire bus to make cabling easy, and avoid wrong wiring.
- It adopts a backward scattering maze and makes it more sensitive to detect the smoke generated from the burning of different materials.
- Sealed rubber type of heat sensitivity component enhances anti-humidity and anti-erosion.
- Three sensitivity levels of the detector are optional at the control panel to suit different environments.
- Drift compensation to reduce nuisance alarms.
- Temperature rising compensation to improve responsive capacity upon different temperature rising status.
- Support sensor fault inspecting and reporting to ensure the system work and maintain well.
- The special production process is to make the device work at high temperatures, high humidity, and high altitude environment.
- ESD static protection grade 12000V, strong anti-interference ability.
