The Protec 3000/FIREBEAM70 is a conventional beam detector, which is compatible with the Protec 3000 range. The 3000/FIREBEAM70 Reflective Optical Beam Smoke Detector includes a motorised head unit containing an infrared transmitter and receiver, a ground-level controller and prism reflector.

The unit uses a 24V infrared transmitter to fire an infrared beam to a prism reflector, the returned beam is analysed for smoke contamination and registers a fire condition at a preprogrammed level.

The beam head incorporates microprocessor-controlled motors that intelligently maintain alignment with the reflector. When commissioned the head accurately aligns itself. In operation, the motorised head will re-align should there be building movement, a problem with new build settlement or environmental change. The unit’s unique ability to self-align means that high-level re-adjustment is no longer required; saving time, disruption and cost, all whilst delivering outstanding reliability that reduces troublesome false alarms.

The supplied controller unit is used to make operational adjustments. The uncomplicated menu system, presented on the controller’s LCD screen, helps simplify maintenance. All adjustments can be made at ground level, including a test procedure and full diagnostics.

The standard unit covers a range of 7 to 70 metres. To increase the beam’s range, additional reflectors can be added. Two kits are available; FIREBEAM70/140KIT for a range of 70 to 140 metres, and FIREBEAM140/160KIT for a range of 140 to 160 metres.

Benefiting from IP65 rated enclosures, on both the motorised head and the controller unit, the beam detector is suitable for hostile environments such as the wash down areas in food processing halls.
