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.

Yep, always happens that way for me. I think maybe there is a clock in these things and that it's just set to go off during the night deliberately. Evil smoke alarm manufacturers!
Never argue with an imbecile; they bring you down to their level, and beat you with experience.

So you'd rather your smoke alarm battery got too low at night, didn't warn you it was low, and when the fire started at 5AM you died without ever being warned as the battery was too low to sound the alarm long enough to wake you up? Sweet dreams...

Most folks don't even change the stinking batteries! Why entrust them to set a clock? How many flashing 12:00 VCRs have you seen? Bad, bad idea. Change the battery, or deal with it.

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.

My favorite is when I yank the damn thing off the wall and remove the battery SO I CAN SLEEP because I'm going to get batteries the next day, and the blasted thing still goes off because there's a built-in backup battery. That's how the detectors were at my old apartment and it was infuriating. Seriously designed to not let you sleep. Gahh.

Gee, why not just make them all wireless devices that send you an EMail telling you that you should consider changing the battery, give you an operational status, maybe a time of how long it's been in operation and tell you when you need to replace the alarm altogether; and why we're at it, make it so that multiple alarms all talk to each other, and each goes off during a fire; OH ... and an admin web page like a router, where you can simply go click a "Test All Now" button and test all the alarms in your house at the same time. and they should also wipe your @$$. :rolleyes: No. Really. I like the entire concept. Investors? Anyone? :-D ok, minus the @$$ wiping part; you're on your own with that.

My are wired directly into the mains, I never have to worry about batteries, are for testing when I grill bacon if the door ajoining the kitchen is left open the smoke alarm usually triggers. Happens once a week so we're safe in our household.

The one in my current appartment is about 10 feet away from my (unhooded) stove. Even with a fan in the window to exhaust if I'm doing anything even minimally steamy (boiling water without a lid on the pot) or smokey (frying pancakes, or carbonizing hotdogs in the oven) it'll go off unless I yank the battery first. In the event of an actual fire there's probably a 1 in 3 chance it won't go off because I forgot to plug the battery back in. The odds of anyone else in the building heading my alarm are probably even lower.

That kind isn't really safe since an electrical fire (or a fire between the breaker box and alarm) could deprive them of power before they go off.

They have considered this problem. The solution is the 10 year lithium battery model.

The clock would be an additional point of failure and one thing you don't want in a smoke alarm is an additional point of failure. They always go off at 2am because battery power is related to temperature so a dying battery nealy always drops below the trigger point when the battery is at its coldest.

They all have battery backups. :rolleyes: obviously
As long as the battery is still good ;)
