Annoying smoke detector, finally pulled off most of them
These batteries never last more than 1 year even though they are all 120v wired, which is supposed to last forever right? they dont.
by basic probability, for every month, in the middle of the night (most likely 3am in the morning), one of them would decide to chirp to telling me that backup battery is weak for replacement, it would take me at least 10 mins to locate the faulty one, and another 5 mins to grab a chair and replace the battery, and thus most likely ruined my rest of night of sleep.
This chiping nightmare kept bothering me, until today, I pulled off most of them , and only leave 3 plugged in, one for each floor.
I wonder who comes up with this idea that for each room, and each area one must have a smoke alarm installed? it is probably that smoke alarm company lobbied the GOV, and GOV thus mandates law to newly constructed home for including these many detectors (totally 13 is insane IMHO, even though it's a 4500sqft hosue), while the cost burden surely got transferred to new home owner.
It is probably the same crap of water rental company screw up new home buyers with an overpriced rental unit that you have to either rent or pay a hefty price... no way you can return it and install one yourself.
