ECN Forum Forums General Topics of the Trade General Discussion Area Goes Off but not On?

I wonder if the saying could have originated from the noise from a kitchen timer turning off. When an oven or microwave timer turns (goes to) off it makes a noise.

To people there is no diffence from a timer running down to off or an alarm tripping - the beeping noise is the same.

Greg, your lucky it was a smoke alarm, I had a CO alarm start beeping at 3am last month.

With a smoke alarm if you don't see smoke or flame you know its the battery, it took me some time to figure out it was the "7 year replace me as I have expired" beep and not the call 911 / gas company alarm.

Standing in the cold in the back yard reading the manual with a flashlight to interpet the beep count I can do with out. I would gladly pay a little more for a photo cell on the unit to prevent the error warnings from tripping at night.
