Beam Detector SL-650QDM

200m, dual modulation, Quad beam active infrared (AIR) sensor with 4 channel selectable frequency and two-way communication  for optimal perimeter security.

The SL-QDM series can be stacked in towers, see the selection and system design guide for all OPTEX active infra-red beams and beam towers.

Use POE encoder PIE-1 to connect your infrared beam sensors to AXIS ACAP cameras and to all leading VMS platforms, enhancing the performance of the security system. 

Main features:

• High power Quad beams with high grade aspherical lenses
• 200m detection range
• Dual modulation - to enhance signal discrimation agians potential interferences
• 4 channel selectable frequency  
• Beam power control selector, a very useful feature to find the peak value, to avoid crosstalk or interferences.
• Integrated Alignment Status Communication (I.A.S.C) to automatically adjust the beam signal power between receiver and transmitter and maintain optimal performance.
• Easy-alignment features with LED and sound indicators on the receiver side to check the level of signal
• Easy-to-see vivid interior colour and Sniper Viewfinder, a telescope lens for optical alignment
