System Sensor BEAMMMK Multi-Mount Kit

although beam detectors are a very effective way to protect open spaces there are several things to consider before choosing a mounting location beam detectors require a stable mounting surface even small movements are amplified tremendously when shooting a beam hundreds of feet across an open space load-bearing walls particularly if they are brick or concrete make the best mounting surfaces structural columns and beams can work well too as long as they aren't expected to vibrate or move over time consider sources of vibration like nearby HVAC units bouncing balls in a gymnasium anything that can cause excessive movement avoid mounting the beam on corrugated metal walls external building sheathing suspended ceilings and steel web trusses as these surfaces tend to shift with temperature or humidity changes the reflector needs to be mounted anywhere from 16 to 330 feet from the detector k
