Description

The 801HEx Intrinsically Safe Heat Detector forms part of the 800Ex Intrinsically Safe Series of MX Addressable Fire Detectors. The 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 heat element of the detector. Software within the controller is used to interpret the returned heat values to raise an alarm or other appropriate response according to the programmed configuration.

The mode of detector may be:
– EN54-5 A1R, rate-of-rise normal ambient
– EN54-5 A2S, fixed 60°C
– EN54-5 CR, rate-of-rise high ambient

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

They are certified:
– ATEX Code: Ex II 1G
– IECEX Code: Ex ia IIC T5
– Cenelec Code: EEx ia IIC T5
