Rich Posted November 16, 2004 Share Posted November 16, 2004 Afternoon. Just had a 10 second power cut here and all the local alarms go off, what is an alarm supposed to do when theres a power cut? Should it not be backed up by the battery and only go off if one of the zones or tampers are activated as normal? Is it normal for an alarm to sound for 20 minutes after a power cut ?

My own home installation definitely DOESN'T go off during a power cut. I did install it myself according to lots of carefully-studied documentation and it works properly. Also, most of the alarms nearby don't go off either. Sounds like the ones near you are faulty or not maintained. Or just maybe there's been a huge power surge that triggered them before the cutout.

amateurandy Posted November 16, 2004 Share Posted November 16, 2004 Sorry, forgot to ask, did they trigger when the power went off, or when it came back on? Link to comment Share on other sites More sharing options...
Rich Posted November 16, 2004 Author Share Posted November 16, 2004 most when it went off i think and a couple when it came on maybe, theres loads around here that do it. Link to comment Share on other sites More sharing options...
Guest Posted November 16, 2004 Share Posted November 16, 2004 Usually the alarm going off during a powercut is due to the fact that the backup battery is knackered, the fuse has blown, or there isn't one, or all 3. A service should pick up on any faulty batteries, maybe a bit of touting should bring some work in round your way!. Link to comment Share on other sites More sharing options...

Guest Posted November 17, 2004 Share Posted November 17, 2004 what is an alarm supposed to do when theres a power cut? 31558[/snapback] Log it. Depending of the panel some of them log ot immediately but take action (reporting to ARC) later. Usually there is a timer (engineer adjustable) which is set for few minute delay before reporting logging or reporting anything. Link to comment Share on other sites More sharing options...

Guest eauctionbargains Posted December 3, 2004 Share Posted December 3, 2004 ok, whats the definition of a trade member? Surely someone who is a trade member would know about basics like battery usage? Link to comment Share on other sites More sharing options...
