ActiV Conventional Heat Smoke Detector

The C4403A1R class A1R rate-of-rise heat detector generates an alarm condition when it detects a sudden rise in temperature or if it detects a static temperature of between 54ºC and 65ºC.

Class A2 Standard (60°C) Fixed Temperature Heat Detector – C4403A2

The C4403A2 Class A2 fixed temperature heat detector generates an alarm condition if the temperature within the protected area reaches a temperature of between 54ºC and 65ºC.

Class B High (75°C) Fixed Temperature Heat Detector – C4403B

The C4403B Class B fixed temperature heat detector generates an alarm condition if the temperature within the protected area reaches a temperature of between 69ºC and 85ºC.
