Electrical Description
The intelligent reflective beam detector is loop-powered and requires no external power supply. Each beam detector draws approximately 5mA in quiescent and 9mA in alarm from the analogue addressable loop and, unless proven by calculation*, it is recommended that no more than ten beam detectors be powered from each loop.
*A loop voltage drop calculation program, known as ‘Loop Calculator’, has been developed by Apollo for use by system designers and is available as a free download from the Apollo website (www.apollo-fire.co.uk)
Operation
The intelligent reflective beam detector is supplied in two versions: one for use at distances of 5–50m from detector to reflector and the other for distances of 50 –100m.
The detector is factory set to a beam obscuration of 35% which is the best setting for most factories and warehouses. The setting can be changed to 25% for offices and clean areas such as theatres or to 50% for hostile areas such as mills or foundries.
The detector compensates automatically for gradual contamination of the lenses in order to avoid false alarms.
The detector is non-latching and resets 30 seconds after an alarm event ceases and in 3 seconds after the removal of a fault.
A termination backbox, part no 29600-241, is available. This allows easy first fixing of the cabling and terminations to the intelligent reflective beam detector. The termination backbox can be surface or flush mounted.
Backward Compatibility
Please note, not all control panels support this beam detector. Please contact Apollo’s Technical Sales department for further information.
Product Information
The Intelligent Reflective Beam Detector differs from a traditional beam detector in that it is a single unit which houses a transmitter, a receiver and the control electronics. The beam detector is available in two versions: a single reflector model for distances of 5-50m and a more powerful four-reflector unit for distances of 50-100m.
