The case is made with imported sheet metal with coatings on the inside and outside surfaces (two coatings on the inside and five on the outside) to effectively prevent the shell from rusting.

The inner thin film sensor can endure the heat continually for numerous times without being affected by it, especially the connector is reinforced to minimize the oxidization under the change of environment, also it prolongs the sensor's life.

Special oxygen outlet device is installed to adjust the temperature change. The micro-hole on the oxygen outlet device can adjust to the change in ambience temperature (room temperature) to avoid the false alarm (non-fire) effectively.

The water discharger is installed on the main body of the detector to eliminate the false alarm and breakdown caused by accumulated water.

This detector has passed strict quality control and repeated tests, which has stable quality and high reliability.
