Eaton Conventional Photo-Thermal Multisensor Detector (EFXN632)

The Eaton EFXN632 is a conventional photo-thermal multisensor detector that combines a photoelectric (optical) smoke sensor with a heat sensor. It is certified to EN 54-7 for smoke detection and EN 54-5 Class A2S for heat, and is used with Eaton conventional and BiWire conventional fire alarm panels.

The detector automatically compensates for gradual contamination such as dust build-up, and fits the common conventional detector base (EFXN520, supplied separately).

Key features

• Photoelectric smoke plus heat (Class A2S, 60°C alarm temperature)
• Automatic drift compensation for dust contamination
• Red alarm LED with 360° visibility via lightpipe
• Positive click when the detector is correctly located in its base
• Optional locking tab to prevent removal without a tool
