Surface Mount/Tamper Resistant PIR Sensor Heads
Using the 2 x M4 screws supplied, fix directly to a standard BESA box with 50.8mm fixing centres in surface mount installations. Alternatively, replace the M4 screws supplied with security type fixings and use in installations where resilience to unsolicited attempts to remove or tamper is paramount; public areas, prisons, secure units etc. Our range of Surface Mount / Tamper-Resistant Heads are available with absence, occupancy and daylight dependency/linking. A Tamper-Resistant version of our Auxiliary Head can be used to extend the area of detection by 6-fold. All options are available in black or white to match their surroundings.
Surface Mount/Tamper Resistant PIR Absence/Occupancy & Light Level Sensor Head (Primary)
- Use for occupancy or absence with daylight dependency/linking. Once a target light level has been set, the Sensor Head will monitor ambient light and turn on/off or dim/brighten luminaires as required.
- The integral infra-red receiver accepts commands from either the Setup or User Remote Control. An LED provides indication of operation.
