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? Quote Link to comment Share on other sites More sharing options...
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 ? Quote Mr Veritas God Link to comment Share on other sites More sharing options...
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 Quote Link to comment 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 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? Quote Link to comment Share on other sites More sharing options...

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.

ffrowley Posted August 13, 2017 Author Share Posted August 13, 2017 Cheers, yeah I've got a few things to go at now. The sensors don't have a sensitivity feature so that's out the window, but yeah I'll try a few of these things, n any more suggestions. Many Thanks Quote Link to comment Share on other sites More sharing options...

MrHappy Posted August 13, 2017 Share Posted August 13, 2017 from screwfix- Quote Electrician Reviewer Would you recommend this product? Yes Overall Rating Value Features Performance Reliability Quality but difficult to setup 14 Jun 2017 By daveje Swanley " I installed this in an understairs toilet. The unit fitted into a 63mm hole and is a 3 wire installation ( L N SwL ) It is suitable for switching LEDs as it has a built in relay.I had major problems setting the sensitivity because this is a Microwave sensor which can 'see' through materials and it was switching when people walked across the landing! but when the 'sens' was reduced enough, to stop this, detection in the WC was less reliable. The unit can only be adjusted when de mounted which is a bit of a pain but stops 'fiddlers' and looks better. I plan on returning this for replacement in case this is a rogue unit when Screwfix have them back in stock. " Quote Mr Veritas God Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted August 13, 2017 Share Posted August 13, 2017 Possibly right with microwave then, should have some sort of adjustment I would expect. Quote Link to comment Share on other sites More sharing options...
ffrowley Posted August 13, 2017 Author Share Posted August 13, 2017 Lux n time adjustment. No sensitivity on this. 40mm hole for the sensor. Looks neat, n I have installed this type many times before no problems in the past Quote Link to comment Share on other sites More sharing options...
