OPERATION / APPLICATION
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. Heat detectors are typically used in environments where smoke detectors cannot be installed, for example, in areas susceptible to fumes, airborne materials and smoke such as in kitchens, loading bays, workshops, wood mills and nightclubs.
