Hard Wired Smoke Detectors


What's the expected life of these devices?

Do paint fumes set them off?

Hard Wired Smoke Detectors


havent outlived one yet--
hard wired is nice as when one alarm goes off - the others will follow. i think you also need to use 3 wire + ground between alarms to accomplish this. they still take a battery as a back up if power goes off.

To answer the first question it will last up to 10 years but I know some case they are still on line longer than that and it will not be very effective due the age and other everoment situation like dust , smoke , critters aka bugs etc , so on

But if you look for manufacter date on the unit if you see over 10 year old it will be good time to chuck { throw it } it and get new one the new smoke alarm units are not that expensive at all.

However just becarefull mix with old et new some will not work very well.

If you still have interconnection devices please contude use the inteconnection circuit.

second answer to your question.,

Yes and No depending on what brand and how senstive it is.


Merci,
Marc

Thanks.

The back of my unit only has a number "98217." I guess that it stands for Feb. 17, 1998, which makes sense since my house is about 11 years old.

One unit has been acting goofy lately, although I recently put down some 5 gallon empty paint buckets nearby that I used to paint a room, along with a large drop cloth. It's also outside the laundry room.

It was initially giving 2 chirps at night only three nights ago and last night, which led me to believe that the battery was dying. I replaced it, and it was fine, but tonight, for no reason, it chirped twice again, and then set off all the alarms upstairs.

I removed the offender and all has been silent since. I'll try to vac it out to see if that makes a difference. Otherwise, sounds like I will be replacing all of them upstairs.
