Fire detection unit

Abstract

This product is a fire detection unit primarily installed on the inner wall of tunnels through which automobiles and other vehicles pass. A fire detector for detecting flames caused by a fire is positioned in the center of the front of the box-shaped main body, and the fire detector is provided with two light-receiving windows that transmit light from the flames. A canopy is provided on the upper front of the main body to prevent condensation from adhering to the fire detector and its light-receiving windows.
