The rate-of-rise heat detector,CM-WS19L,is designed to sense the rapid or abnormal rise in temperature of air.If ambient temperature rises rapidly, the air in chamber expands and presses the diaphram to close the contact point to give advanced warning. When a slower temperature change occurs, the expanded air escapes through a bleeding hole to keep the pressure balanced so that the fault alarm never occurs.

1.Rate-of-rise heat detector detects intense fires by

   quickly responding to rapid temperature increases.
2.Mechanical operating principles ensure the long-term 

   durability and the least malfunction.
3.Self-restoring ensures those elements repeated use
4.High quality components are fitted for greaterreliability.
5.Red indication lamp lights when detctor is activated.
6.High-temperature-enduring plastics and fire-proof material

  are used to build up  the main body of the detector.
7.The base is in common with other detectors made in

   this company for the facilitation of installation.

8.Connections are non-polarized to avoid wriing mistakes.
