How to stop constant alarm output on my Bosch DS484Q Security System?

  Samantha GouldAug 1, 2025
  A constant alarm output from your Bosch Security System can be caused by several factors. Something might be blocking the beams, or the optical modules or covers may need cleaning. It could also be due to an improper channel selection or synchronized wires not being connected. To resolve this, remove any objects blocking the beams, clean the optical modules and covers, select the proper channel, and ensure the synchro wiring is correctly connected.

Why does my Bosch Security System have frequent false alarms?

  William MillerAug 7, 2025
  Frequent false alarms in your Bosch Security System can occur due to several reasons. An object might be blocking the beams, or the beam interruption time might be set too short. Electrical noise or radio frequency interference (RFI) nearby, wiring too close to power sources, an unstable installation site, being out of the maximum protection range, an inappropriate Beam Power Control level, or frost or dew can also cause this issue. Try removing any obstructions, decreasing the sensitivity, changing the installation site or the wiring's routing, fixing the installation site, reinstalling the units within the maximum protection range, readjusting the control level, or attaching the optical heater.

What to do if my Bosch Security System has no alarm when beams are blocked?

  John YoungAug 13, 2025
  If your Bosch Security System doesn't trigger an alarm when beams are blocked, it could be because the beams are being reflected into the receiver, the beam interruption time is set too slow, or there is not enough beam power. You can try removing any reflective objects or changing the installation site, increasing the sensitivity, or increasing the beam power.
