paradisiaque Posted April 14, 2020 Share Posted April 14, 2020 Hello, I have just finished some work to tidy up the wiring on the Accenta Gen4 system fitted in my flat. Basically what I did was re-route a lot of the surface cabling under the floor, and also change a couple of the sensors. Now the system is up and running again it all seems to work fine, apart from the door contact. The door used to have a surface mounted Honeywell contact, and one of the changes I made was to swap that for a flush contact hidden in the doorframe (part is CQR FC508/WH). When I test the output from contact back at the panel with a multimeter is it fine; reads 2 Ohms with the door closed and then open circuit with the door opened. However when I connect it to the panel it doesn't respond normally. On walk test mode the panel usually shows the door contact open even when the door is closed (and the terminals on the panel read low resistance with a meter). Once or twice on walk test it has responded correctly, but when the system was next power cycled it then went back to the same problem. I have tried bridging the terminals on the panel with a bit of wire and with that done the response is totally normal. Because both the contact and the panel seem to operate normally I do wonder if this might be interference of some kind, but I don't know of any way of checking that. If you have any ideas that I could try to fix this that would be great as it has me a bit stumped! Cheers, Nick Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted April 14, 2020 Share Posted April 14, 2020 just to start with have you cut any links as you have an eol door contact on a non eol panel? You sure its reading 2 Ohms, or 2K etc? Quote Link to comment Share on other sites More sharing options...
paradisiaque Posted April 14, 2020 Author Share Posted April 14, 2020 Ah thankyou that's really helpful. I hadn't realised the contact had an EOL. I've just checked the reading on that circuit at the panel again in case I had the meter on the wrong range or something, and it definitely is 2 Ohms. Is there a way of configuring the contact to work with this panel? or should I replace it with a different kind of contact? Thanks, Nick Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted April 14, 2020 Share Posted April 14, 2020 yes you need to remove both jumpers on the contact but if you are getting 2 ohms thats a good reading. If you look at the install sheet it shows how to wire this contact for non eol use. Is your alignment good between magnet and contact, there isnt much 'play' laterally? If you want to check for interference (unlikely) you can link out at the door and prove the cable. Quote Link to comment Share on other sites More sharing options...
paradisiaque Posted April 14, 2020 Author Share Posted April 14, 2020 Thanks for that. I had a look at the PDF datasheet on the product page here: http://www.securitywarehouse.co.uk/brochure/FC508.pdf That doesn't seem cover how to configure the jumpers, is there something else that would have instructions to set up for non-EOL connection? Good idea to check the alignment as well, will do that once the wiring is set up correctly. Cheers, Nick Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted April 14, 2020 Share Posted April 14, 2020 No if you look on the sheet that came with the contact it shows you the wiring config. Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted April 14, 2020 Share Posted April 14, 2020 you obviously want the double pole wiring config for an accenta Quote Link to comment Share on other sites More sharing options...
paradisiaque Posted May 9, 2020 Author Share Posted May 9, 2020 Just to say thankyou, that sorted it completely - the alarm works perfectly now! Cheers, Nick Quote Link to comment Share on other sites More sharing options...
