Fire Alarm System

Point type multi-sensor smoke and heat detector


Product 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.

Sealed robber 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.

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