Palladium Heat Detector

The Conventional heat detector uses a state of-the-art optical sensing chamber. This detector is designed to provide open area protection and to be used with most conventional fire alarm panel.The Conventional rate of rise heat detector uses thermal component to detect the temperature changing in the environment. It can enable fire alarm when the temperaturedifference achieved the setting rate of rise temperature valuereach the setting fixed value.
