Smoke Alarm Engineers - why can't they think?
-
Anyone that has a battery operated smoke alarm knows that "chirping" sound when the battery needs to be replaced. Studies have shown the battery is low, not dead, and the chirping will continue for 4-6 weeks if not changed. Everyone knows that the chirp never happens during the day. It always occurs in the middle of a deep sleep. Mine went off 1:15am last night. It's my backup battery for my C0 detector (which is plugged in). Why not place a simple clock mechanism in these alarms? Let the customer set the time for the warning chirp to start, and when to stop. Make sure the time frame is at least 15 hours long, so the odds of the person not hearing the chirp during work has been taken into account. I know the easy way is to just change them on regular intervals, like the daylight savings time changes, but this is an easy fix that would not drain much battery power, and help to avoid issues like mine in the future.
It is not just when you here the chirp, but also determining "which" one of the detectors is doing it. Also, if it is chripping, does it actually fail a test... Too many rooms with too many detectors can be a pain!

Aren't you supposed to manually test it every few weeks or so anyway? I think I'd prefer beeing woken up during the night due to a low battery warning than not at all during a real fire. But... Hey! That's just they way I am.
