801PHEx Optical Smoke + Heat Detector

The 801PHEx Intrinsically Safe Optical Smoke and Heat

Detector forms part of the 800Ex Intrinsically Safe Series of

MX Addressable Fire Detectors. The detector plugs into an

MUBEx 4” Universal Base or 5B 5” Universal Base.

The detector is designed to transmit, to a remote Minerva MX/T2000 fire controller, digital signals which represent status of the optical smoke and heat elements of the detector.

Software within the controller is used to interpret the returned optical and heat values to raise alarm or other appropriate response according to the type of detector configured in ‘MX CONSYS’.

The detectors are designed to comply with EN/IEC 60079-

0:2006, EN/IEC 60079-11:2007 and EN/IEC61241-

11:2006 for Intrinsically Safe apparatus.

Features and benefits:

• The optical smoke detector can be selected in one of two logic modes as follows: Normal and fastlogic modes.
• The detector may be used as two separate detectors using two loop addresses.
• Day/ night switching.
• Sensitivity switching.
• Self-test facility.

The mode of detector may be:

• Mode 1 - Optical smoke only detector (sensitivity High, Normal or Low)
• Mode 2 - HPO smoke detector (sensitivity High, Normal or Low)
• Mode 3 - Optical (sensitivity High, Normal or Low) plus heat fixed temperature 60°C (A2S)
• Mode 4 - Heat only normal ambient R-o-R (A1R) detector (no sensitivity selection)
• Mode 5 - Heat fixed temperature 60°C (A2S) (no sensitivity selection)
• Mode 6 - HPO (sensitivity High, Normal orLow) and heat fixed temperature 60°C (A2S).
