ffrowley Posted August 13, 2017 Share Posted August 13, 2017 Lights switching on via occupancy detectors every time the external door is opened and the door alarm sensor activates. The alarm and lights are on different circuits, and cables do not run in close proximity to each other. Has anyone had this before?

MrHappy Posted August 13, 2017 Share Posted August 13, 2017 I'd guess the occupancy sensor is on a suspended ceiling & when the door is opened the tile is moving enough to put the lights ons.... What is the "door alarm sensor" - just a contact ?

ffrowley Posted August 13, 2017 Author Share Posted August 13, 2017 The door alarm is a contact with a buzzer that sounds on the alarm panel. The ceilings are plastered and the sensors are not on the same floor as the external door Link to comment https://www.thesecurityinstaller.co.uk/community/topic/41479-john/#findComment-467140 Share on other sites More sharing options...

sixwheeledbeast Posted August 13, 2017 Share Posted August 13, 2017 Surely the occupancy sensor is just doing it's job? Assuming there ultrasonic or microwave and not IR. If the only thing "connecting them" is the audible sound of the chime on the door have you disabled the chime to test? The occupancy sensors may need adjusting. Also who's John, the resident ghost?

ffrowley Posted August 13, 2017 Author Share Posted August 13, 2017 -I'm sure the sensors are IR I'll have to have a look when I go back. -I haven't disabled the chime yet... -I've installed the lights with occupancy detectors Link to comment https://www.thesecurityinstaller.co.uk/community/topic/41479-john/#findComment-467158 Share on other sites More sharing options...

ffrowley Posted August 13, 2017 Author Share Posted August 13, 2017 Could possibly have a damaged cable or loose connection on the alarm side. How would that switch an occupancy detector for a lighting circuit on tho? These circuits are both separate?

Mask your sensor(s) over with electrical tape, open door external *IF* there's a weird interconnection between the systems your lights will come on. I assume opening the door is causing something to move within the area of the occupancy sensors eg- blinds, house plants or some weird reflection on the glass of the opening door reflecting onto the glass of another building into the room with the occupancy sensors Reducing the sensitivity of your occupancy sensor(s), is where I would start.
