Hi everyone,
So the smoke alarm at my unit has been happily chirping since yesterday morning and last night. I think the problem lies in the battery running low. I have only been living in the unit for 10 months, shouldn't the battery last at least a year? In my previous place, I have never had this problem, not even until the end of my four years stay there. I was reading this article http://www.realestate.com.au/blog/the-what-why-how-for-smoke… and it is mentioned that with hard-wired unit, it is not tenant's responsibility to change the battery. My rental agent, being the helpful body they are, said it is not their issue.
My question is, considering that it has been less than a year since my residency in the unit, and as the smoke alarm looked like a hard-wired unit, is it my responsibility to change the battery?
I tried to open the cover of the smoke alarm, it said on it to turn to remove, I did as follow and it got stuck. Even pushing or pulling the unit while turning the unit did nothing. The alarm looked really old, so may be it is just rusty. I have asked my agent for instruction manual but, as usual, I got nothing. Is there other way to open the cover of a smoke alarm? I have attached the picture (http://imgur.com/sqkYSIC) if anyone can help me :)).
Rotate/turn the whole thing counter clockwise a little, and it should come off the base plate. The chirping could be the battery (just put a new one in and see if it stops). But it could also mean that the alarm needs to be replaced. Smoke alarms usually expire between 5-10 years. If it still chirps with a new battery, the unit needs to be replaced.
