Description

TrueAlarm heat detectors are self-restoring and provide rate compensated, fixed temperature sensing, selectable with or without rate-of-rise temperature sensing. Due to its small thermal mass, the detector accurately and quickly measures the local temperature for analysis at the c.i.e. Rate-ofrise temperature detection is selectable for either 8.3°C or 11.1°C per minute. Fixed temperature sensing is independent of rate-of-rise sensing and programmable to operate at 57.2°C or 68°C. In a slow developing fire, the temperature may not increase rapidly enough to operate the rate-of-rise feature, however an alarm will be initiated when the temperature reaches its rated fixed temp. setting.
