Digital PIR detector
September 2017, Perimeter Security, Alarms & Intruder Detection, Residential Estate (Industry), Products
The BMD500 series of detection devices readies a security system for the unexpected by providing protection for every room, corner and corridor. The detector features intelligent signal analysis for reliable detection, pet immunity up to 25 kg and a slim design that complements any décor.
Advanced ASIC-based processing provides detection and false alarm rejection to help keep people and possessions secure. Quad Linear Imaging Technology provides sharp analysis of body dimensions and differentiation from backgrounds and pets.
Effective motion detection is dependent on a sensor’s ability to identify intruders and provide true false alarm resistance. The LC series of detection devices pinpoints intruders through digital signal processing. Digital information is more accurately analysed using software and is not subject to signal degradation caused by amplification, noise, distortion or signal clipping.
Once the detector is installed at the recommended height, installers simply conduct a brief walk-test, to make any necessary adjustments, and the unit is ready to perform. LEDs can be viewed at a glance and help the installer identify the detection range from any distance or angle within the coverage pattern.
The detection range of the motion detector is adjustable to about 3 m to 12 m. A potentiometer can be adjusted clockwise or counter-clockwise to increase or decrease the range respectively. For optimum performance, range should be adjusted so that it effectively protects the dimensions of the intended area. The LC-100-PI is factory-set for 84%.
When choosing a location for the detector, be sure to consider the following:
• Do not aim the detector at reflective surfaces.
• Avoid locations that are subject to direct high air flow.
• Do not locate the detector in the path of direct or reflected sunlight.
• Do not place next to large obstructions that may limit the coverage area. For more information contact Provident Technologies, +27 (0)82 4451 541, info@providenttech.co.za, www.providenttech.co.za.
