The F2000 infrared optical beam detector is the ideal answer to large open plan spaces with high ceilings; for example factories, warehouses, churches, museums, hazardous areas, shopping and leisure centres.

The product features 3 selectable ‘Alarm Threshold’ settings of 1.25dB at 25%, 1.87dB at 35% (default) and 3dB at 50%, which is recommended for hostile and extreme environments. It also has a battery powered fall-back supply so if, for any reason, the power is cut in a building, the F2000 will still relay a break in the beam.

The F2000 is also benefited by the use of LED’s. The red LED, located on the door, indicates a fire and the continuous yellow LED, located internally within the unit, indicates a fault.

The response of the fire relay, used to trigger the alert, is dependent on your decision of chosen mode. “Auto Reset Mode” resets the fire relay approximately 5 seconds after its return to its usual threshold state, and “Latching Mode” causes an indefinite constant alarm once the fire relay has been activated.

FireRay 2000 also features a fault relay setting that is triggered when the infrared beam is suddenly obstructed to a level of 93% plus for approximately 10 seconds. After the condition has been rectified the fault relay will reset within 4 seconds. The F2000 has been designed, manufactured and certified to BS5839 Part 5 and has also gained VdS, UL and CPD approvals.
