Addressable Multi-Mode Heat Sensor – 400003FIRE-0003X / CAH330

Cooper CAH330 Intelligent Addressable Multi-Mode Heat Sensor (MAH830 / FXN725)

These ranges of intelligent addressable sensors have been specifically designed to operate with Cooper intelligent addressable fire systems.

All sensors are third party approved to the relevant section of EN54 (part 7 for smoke detectors & part 5 for heat detectors).

The heat sensor (CAH330) can be set to one of 3 modes 77ºC / 92ºC and rate of rise. These sensors are designed to be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used, for example where there is a high level of dust, fumes, steam or smoke under normal conditions.

Surface mounting with CAB300 base


50m² or 100m² (subject to local standard)

Soft addressed for quick commissioning

All the intelligent addressable sensors are soft addressed allowing engineers to program the device at the panel instead of on location, reducing commissioning time and cost.

360° Visibility light pipe LED technology

An onboard light emitting diode (LED) utilises light pipe technology to emit a light which is visible in 360° for peace of mind and easy maintenance.

Discrete, simple design

Designed to integrate into any decor, Eaton’s range of addressable optical, multi-mode and photo thermal detectors all share a consistent clean design.

One installation point. Multiple devices.

Eaton’s range of addressable detectors have three types of detector base to meet the challenges of the site:
  • . Standard detector base (see specification tab)
  • . Duct mounting base for monitoring heat, air conditioning and ventilation (HVAC) ducts
  • . Sounder bases including options for the addition of a LED or visual alarm device beacon


  • . Quick and simple to install
  • . Single “multi-mode” heat sensor
  • . Wide viewing angle for increased LED visibility
  • . Common mounting base
  • . Positive “lock” indication
  • . Discreet design for incorporation into any decor
  • . Easy to maintain/service


  • . Soft addressed
  • . Integral short circuit isolator
  • . Single address
  • . Wide range of sensor types
  • . 360° visibility LED using lightpipe technology
  • . Drift compensation
  • . Removable detector chamber
  • . Aesthetically pleasing
