Product overviewThe C Series intelligent addressable heat detectors include fixed-temperature model 5251CPI and rate-of-rise model 5251RCPI. The detectors continuously measure ambient temperature and report to the fire panel; the panel initiates alarm when the configured threshold is exceeded. Rate-of-rise detectors also alarm if temperature increases rapidly. A configured fire panel will display the location of any detector that reports alarm, fault or maintenance.
Key features- Intelligent addressable (IA) communication with fire panel
- Temperature threshold configurable in the fire panel
- Rotary address switches for setting loop address
- Dual red LEDs indicate active detectors; LEDs blink when polled (blink can be disabled from panel)
- Optional remote LED indicator available
- Magnet test function activates detector and bypasses inbuilt delays for testing
- Compatible with B501AUS, B501AP and other System Sensor intelligent addressable bases; compatible bases may provide anti-tamper
- SAI Global StandardsMark listed to AS 7240.5 (certificate SMHK25312)
