Why is my fire alarm making a high pitched noise?
When smoke detectors are activated by the by-products of combustion (smoke) they emit a loud screeching noise. If the detector is just emitting an intermittent “chirping” noise it means that the battery needs to be replaced.
How do you get a smoke alarm to stop chirping without a battery?
If your alarm is still beeping, even without a battery, try taking an air blower (similar to one used for keyboards) and blow inside the alarm’s vents. You can also do this while changing the batteries.
Why do fire alarms go off for no reason?
The most likely reason smoke detectors go off unexpectedly is that people aren’t changing the batteries in them often enough. That’s because smoke in the air will reduce the current. If your battery is dying, the current that’s flowing through your sensor also goes down. And so you can get a false positive.

Why is the smoke detector without battery chirping?
Sometimes dust finds its way into your smoke detector and gathers in the sensing chamber, which can cause your detector to chirp. Dust can also cause false alarms, so if you’ve heard your alarm go off at random times, that could also indicate you have dust built up in your detector.
Why will my smoke detector not stop beeping?
Smoke detectors are intended to make a chirping noise once the battery needs changing. This usually occurs in electrical powered smoke alarms with a battery backup. When this happens, the way to stop the chirping noise is to reset the smoke alarm to manually clear the error from the processor.

Why does my house alarm make a high pitched beep?

Given the pitch and the proximity to the ceiling and how well the sound echoes it can drive you nuts.
Why does my smoke alarm keep beeping and chirping?

Why does my car alarm keep beeping when its out of batteries?
If so, they may be beeping because the batteries are out of them. Other source of beeping (at least for me) are my uninterruptable power supplies. If you have any of those, I’d check them too. Another possibility is a dead/dying battery backup for an alarm system.
