JasonOfOz Posted October 9, 2013 Share Posted October 9, 2013 Hi Everyone, We recently had 4-5 false alarms caused by this detector. I've never had any issues with it before so perhaps it is faulty. Funnily enough it is mounted next to a wireless access point (been there happily together for a while now, although it was installed after we put our detector up). The WAP can get quite warm. Surely the WAP wouldn't trigger an activation? or would it? We will be replacing it anyway just in case but I thought it would be worth getting your respective views as we can't seem to figure out what is tripping the detector. (only installed 12 months ago) Thanks! Jason Link to comment Share on other sites More sharing options...
AdrianMealing Posted October 9, 2013 Share Posted October 9, 2013 Check the frequency the WAP is using, the TMD I think is 10gHz microwave, the WAP if standard should be 2.4 or 5 gHz but I have seen some custom jobs at weird frequencies, might be worth checking amealing@texe.com Head of Industry Affairs Visit Our Website Texecom Link to comment Share on other sites More sharing options...
jiml Posted October 9, 2013 Share Posted October 9, 2013 Very odd. How close is the WAP? Check the frequency the WAP is using, the TMD I think is 10gHz microwave, the WAP if standard should be 2.4 or 5 gHz but I have seen some custom jobs at weird frequencies, might be worth checking yes. They are10.6gHz. I don't know of any wifi that high. But if very close, it could be just the proximity. Still odd though. Link to comment Share on other sites More sharing options...
JasonOfOz Posted October 10, 2013 Author Share Posted October 10, 2013 Thanks guys, I'll have the team take a closer look when they are there and see what comes of it. Link to comment Share on other sites More sharing options...
cybergibbons Posted October 10, 2013 Share Posted October 10, 2013 I've seen some APs produce harmonics, especially if they are iffy brands or anyone is using custom firmware and pushing power outputs. Also dodgy switch mode power supplies. But they shouldn't cause problems with a microwave detector. I have a blog, some of which is about alarm security and reverse engineering:http://cybergibbons.com/ Link to comment Share on other sites More sharing options...
JasonOfOz Posted October 10, 2013 Author Share Posted October 10, 2013 I can't see how there would be interference. It's a Cisco WAP - aren't all devices CE marked for a reason? So if it's not the WAP and it's generating an alarm condition, what else could it be? We are going to swap the detector out but it's difficult one to diagnose. Possibly for another topic but are we as installers liable for the key-holder response charges if they are constantly getting "false" alarms?

james.wilson Posted October 10, 2013 Share Posted October 10, 2013 rf devices do affect things, but is the detector false alarming on both sides (ie confirming)? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Cubit Posted October 10, 2013 Share Posted October 10, 2013 I may be wrong but I seem to recall whistle having a similar problem. Link to comment Share on other sites More sharing options...
ChrisMurphy Posted October 10, 2013 Share Posted October 10, 2013 If you are concerned bench test it. Or just wait until the new one either fails or stays secure. As asked above, is it going into alarm on both zones i.e. confirming? 30 years of experience, ssaib approved family business.

JasonOfOz Posted October 10, 2013 Author Share Posted October 10, 2013 It seems that only the PIR (zone 2) is going active. Link to comment Share on other sites More sharing options...
