Curtain Barrier Sensor – 4 Beams

ENFORCER Long-Range Curtain/Barrier sensors can be used in windows, doorways, skylights, fence tops, walls, and other confined spaces for both indoor and outdoor perimeter security. The trigger is programmable to activate upon the simultaneous breaking of two adjacent beams or of any single beam.

LED on TX and RX are on, but the buzzer continues to sound when trying to align
  • Unmount the strike and check that the wiring connector is connected properly.
  • Ensure the wiring connector is connected to a 12 or 24VDC source.
  • Use a multimeter to test that the strike is receiving the proper voltage and amperage. If it is not, it may be necessary to use heavier gauge wires or increase the output of the power supply.
  • Make sure the activation device (keypad or push-button switch) is working properly.
LED on RX flashes, TX LED is off, buzzer gives off short beeps
  • Check that the door latch is operating properly, and replace if necessary.
  • The position of the electric strike may need to be adjusted by moving it or adding washers or shims.
Alarm sensitivity is very slow
  • Check whether 2 adjacent beams are already blocked
  • Check for any reflective objects or surfaces that may reflect light to the RX. Repaint the surfaces are change the installation to reduce reflection
  • Check for any bright light source pointing directly toward the RX
  • Adjust the TX power to a lower level on both the TX and RX (J4 jumper)
Alarm is not triggered
  • Block beams and ensure that the buzzer sounds
  • Check wiring continuity to the alarm output relay
  • Ensure that the wiring to the alarm panel has not been damaged
  • Ensure that the TX and RX are not beyond the rated detection range
  • Ensure that the power is correct and is the same on both RX and TX
  • Check the alarm panel programming
False alarms
  • Check to see if there may be interference from other sensors and adjust installation if needed
  • Check leafy vegetation near sensors and cut back if needed, or program for two-beam use
  • Check for possible rainwater running from the roof into the beam and correct if needed
  • Check for other interference outdoors and provide shelter as necessary
