Description

The 801PHEx Intrinsically Safe Optical Smoke & Heat Detector plugs into a 5BEx base. The detector is designed to transmit to a remote MX fire controller, digital signals which represent the status of the optical smoke and heat elements of the detector. Software within the controller interprets the returned optical and heat values to raise an alarm or other appropriate response according to the type of programmed configuration.

The mode of detector may be:
– Optical smoke only detector (High/ Normal/Low)
– HPO smoke detector (sensitivity High, Normal or Low)
– Heat only rate-of-rise (A1R) detector (no sensitivity selection)
– Heat fixed temperature 60°C (A2S) (no sensitivity selection)
– Optical (sensitivity High, Normal or Low) combined with heat fixed temperature 60°C (A2S)
– HPO (sensitivity High, Normal or Low) combined with heat fixed temperature 60°C (A2S)

These detectors are designed to comply with EN 50 014 and EN 50 020 for intrinsically safe apparatus.
