SUMMARY

The forum discussion centers around troubleshooting a chirping smoke detector, specifically one that is hardwired into the electrical system but also has a backup battery. Users confirm that the chirping indicates a low battery, even when the device is hardwired. Key steps include turning off the breaker before unplugging the device and ensuring the backup battery is removed to stop the chirping. Participants also discuss the challenges of finding smoke detectors that do not have distracting LED lights and the importance of having a reliable backup battery for safety.

Which is why prompting you to remove the battery to shut it up goes against the purpose. I should check the other alarms and see if any of them have batteries.

Say the fire cuts off the electricity to the alarm and there is no battery...you're a crispy critter.

Why not have a "no battery" indicator light? Like a bright blue light that will alert you that the battery is either completely dead or not even there? Perhaps the light could be inside the unit and make the entire alarm glow blue?

Hey come on now, they cost like 10 bucks! What do you expect!

Although the indicator beep sums up pretty much all of those. It beeps to let you know the battery is near dead, so you go and replace said battery. I wonder if the battery powers the beep, or if the beep is powered by the hard line and is triggered when the battery power drops below a certain point.
It would make more sense for the beep to be powered by the hard line, because a beep being powered by the battery would drain it further.
But wouldn't it beep if there was no battery?
Oh I have no idea.
