The Eaton Cooper CAH330 is an intelligent addressable multi-mode heat sensor for Eaton's Cooper addressable fire systems.
It can be set to one of three modes (rate of rise or one of two fixed temperatures) from the panel, and is designed for areas where dust, fumes, steam or smoke under normal conditions could cause false alarms with smoke detection.
Key features
- Three modes in one sensor: rate of rise, fixed 77°C (class BS) and high fixed temperature (class CS)
- Soft addressed (auto address) with integral short circuit isolator
- 360° visibility LED using light-pipe technology
- Drift compensation
- Fits the common CAB300 standard base (also compatible with the CAS380 sounder base)
