Installing interconnected smoke detectors
During last nights storm our phone line got knocked out. No big deal except it set the alarm panel beeping about a phone fault. Usually I can press the * to quiet this beep but last night I could not. So I had to shut it off. Then we realized that we no longer had smoke detectors. So off to Walmart I went to get some battery powered ones.
So that got me thinking about installing some interconnected hardwired ones as backup. So just looking for advice on brands, how to they communicate with each other, etc. Do they need to be on their own circuit? Do they have battery backup or do I need to put them on a generator circuit?
Since they are strictly for backup, I am only planning on using 4 of them, master, daughter's BR, living room and basement. Or do I need to go all in on this?
