Fireray 3000 Exd Flameproof Optical Beam Smoke Detector

Summary

The Fireray 3000 Exd is ideally suited for the protection of large areas, with potentially explosive atmospheres, against smoking fires. Fireray 3000 Exd comprises an infrared transmitter and a receiver, both of which are ATEX-certified for use in Group 2 hazardous areas. There is a separate, safe area, wall-mounted remote/low level control unit to allow adjustment and testing from a convenient non-hazardous location.

The product is designed for large enclosures within oil rigs, refineries, ordnance stores and similar premises. It provides an early warning of smouldering or strongly smoke-generative fires, which may not be picked up by flame detectors installed in many hazardous areas.

Operation

The Transmitter head emits a narrow beam of infra-red light to an associated Receiver head. Once smoke crosses through and thus obscures the IR beam path, the signal strength at the Receiver drops below a preset level which in turn results in an alarm condition.

The Fireray 3000 Exd has been designed so that it can be installed by one operator, with its laser assisted alignment method combined with easy to use alignment LEDs offering visual feedback. Integrated laser alignment aid can be activated at the controller.

The Fireray 3000 Exd also has a feature which allows for the transmitter to be powered from the controller by wiring directly, thus reducing the number of power supplies required.

The low level system Controller incorporates a LCD display, which offers a full icon-based, easy-to-use interface unit. This Controller enables ease of commissioning, testing and maintenance of the beam detection system. During commissioning the detector’s fire sensitivity thresholds can be selected, along with the user variable time to fire and time to fault settings.

The system is fully compliant with the requirements of RoHS and WEEE.

The Fireray 3000 Exd comes with a 5 year warranty as standard. With continued servicing and maintenance, the lifetime of the beam can exceed 10 years.

The Fireray 3000 Exd comes supplied with a Cable Gland Type E (Double Compression for Armoured Cables), approved by VdS.

The “E” type double compression gland is a certified Flameproof Ex d, providing a controlled Exd seal on the cable inner sheath, an environmental seal on the outer sheath and a detachable armour specific clamping system for the wire armoured cables.
