Explosion-proof smoke detectors

The Fireray 2000 EExd beam-type smoke detector is certified to the ATEX 94/9/EC standard for use in Group 2 hazardous areas, bringing the benefits of wide-area smoke detection to environments with a risk of explosion. It is suitable for oil rigs and refineries, petrochemical plants, power stations and storage depots.

Each detector comprises three parts — an infrared transmitter and a receiver placed on opposing surfaces and a low -level control unit — all ATEX certified.

Any smoke entering the beam path is detected by the loss of signal strength between the detector heads. The beam is effectively 15 m wide and the heads can be up to 100 m apart. The product can cover an area of up to 1500 m².

The detector has a drift compensation feature to guard against gradual loss of signal caused by dust build-up on the detectors or building shift, reducing the incidence of false alarms.
