Product Features
Differential localized detector designed to detect rapid or abnormally rising temperatures. If the ambient temperature rises rapidly, the air in the box will immediately expand and press the metal film, causing the electrical contacts to conduct, thus outputting an alarm signal. But when the temperature changes slowly, the expanded air is released through a tiny vent to maintain pressure balance, so false alarms never occur.
- React quickly to fires that rapidly increase in temperature.
- Mechanical action principle, can be used for a long time and is not prone to failure.
- It can automatically return to its original state after action and can be used repeatedly.
- Silver-palladium alloy electrical contacts have excellent electrical conductivity and are not easily damaged.
- The exhaust valve adopts optical fiber glass tube, which is resistant to high temperature, oxidation and moisture, and has stable quality.
- The main body is made of fireproof plastic and has a beautiful appearance.
- The chassis adopts a shared design, which facilitates installation and material preparation.
- There is no polarity distinction in wiring, which can avoid wiring errors.
