Betsy, It is recommended to replace the batteries every six months, The time change in the fall and spring use to be good times, but now the government screwed that up.... But know, from my experience with them, they should not all beep when the battery gets low in one. I would have the wiring checked out. If they are not connected right, they might not work when they need to. And if they are more then 7 years old they should be replaced. Each detector should have 3 wires, white, black, and red. The white and black are for the power, and the red is the signal wire, that tells them to go off together. It is simple to hook up, just make sure all colors are matched up with each other. Then their should be a test button on them, press the test button on one, and they all should go off. Michael _____
From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Betsy Whitney Sent: Friday, October 17, 2008 1:00 PM To: [email protected] Subject: [BlindHandyMan] Question about smoke alarms Aloha, This is a question about smoke alarms that are hardwired with battery backup. The house belongs to my friend and the wiring was redone about a year and a half ago, to bring it up to code. Are these alarms generally wired in such a way that if one of the batteries gets low, all of the alarms will start beeping? This happened about six months ago and it took awhile to figure out which alarm battery needed to be replaced. Then, a couple days ago, another alarm started beeping by itself, but when she replaced that battery, it didn't stop. She finally started replacing batteries in all the alarms and when she replaced the one in her hallway, an alarm that was not beeping, the beeping stopped. Is it usual for the batteries in these hard-wired alarms to get low every six months? Thanks, Betsy [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
