The Trician Posted January 27, 2010 Share Posted January 27, 2010 Just been to look at a fault - PIR sensor controlling one bulkhead light, and, it seems, some kind of automatic door bell. PIR unit has the following info - There's no Brand label. 'Live carrier Unit'. Type PRI Q18T 6220 G3. Max load 1200W Basically, the bulkhead light won't switch off once the PIR unit switches it on, and the doorbell won't stop chiming! I'm not sure how the doorbell thing is controlled - All there is, is a white plug-in box (looks like a Mains adaptor) which you can plug in anywhere in the house, so I am guessing there's some wireless involved. There must be some kind of carrier signal being triggered into the mains when the PIR unit is triggered. Not familiar with this kind of set up. Can't identify a replacement - so any assistance would be most appreciated. Cheers TT Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted January 27, 2010 Share Posted January 27, 2010 There are various units that do this. Is it something like this? http://www.securitywarehouse.co.uk/catalog/index.php?main_page=product_info&manufacturers_id=84&products_id=954 Quote Link to comment Share on other sites More sharing options...
The Trician Posted January 27, 2010 Author Share Posted January 27, 2010 Hi, Many thanks for your prompt reply. No, the adaptor does not allow anything to be plugged into it. I believe it is just a self-contained rx chimer unit. The actual PIR sensor is situated outside the back door, has an adjustable head, and the info I gave in my 1st post is printed on the back of it. It looks to have two white cables and two blue cables inside it's housing. There are no markings etc on the indoor plug-in chime unit. It is just a plain white plastic pug-in box.

Secware_Tech6 Posted January 27, 2010 Share Posted January 27, 2010 Sorry thats the only one that we currently supply. Its works in the same way, ie it chimes when a compatible sensor is triggered. Quote Link to comment Share on other sites More sharing options...
