Hardwired smoke detectors can still beep even if there is no battery. Possibly the backup battery might have been activated and that can signal a problem. The backup battery may have run out and that is causing your hardwired smoke detector to chirp.
If the alarms are still on the ceiling with the batteries removed, the smoke alarms have to beep to remind you to add new batteries. If they still beep after new batteries are inserted your smoke alarms might be older than 10 years or your replacement batteries were flat. Ei recommends EverReady 522 or Duracell MN1604.
A blast of compressed air will often remove the dust particles that are causing the beeps. Sometimes the device may need a more thorough cleaning with a vacuum and/or a wipe. If these methods don't stop the chirping, you may need to replace the entire unit.
When a smoke detector keeps beeping even after replacing its battery, it can mean that there is something preventing it from detecting the battery. It can also mean that there are too many system errors overwhelming its processor. You can try resetting the smoke alarm to manually clear the error from the processor.

Dust and debris can easily accumulate inside your hard-wired smoke alarm, causing that incessant chirping sound. This build-up can interfere with the sensing chamber, triggering false alarms. To prevent this, make a habit of cleaning your smoke detectors regularly.
If your fire alarm is a sealed unit with no replaceable battery, then either organise a replacement with the manufacturer (if within guarantee) or alternatively purchase a new one.
Some smoke alarms have a processor that retains certain error conditions, such as a weak battery. The error condition should reset when the battery is replaced, but sometimes it doesn't and must be manually reset to clear the error.
The beeping sound the low battery alarm makes can become very annoying but can be disconnected by removing the drained battery from your home alarm system panel. Make sure to replace the drained battery with a new one to keep your home alarm system functioning properly.
Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping. If this doesn't work, grasp the device and turn it counterclockwise. It should detach from the base so you can open the battery compartment in the back. Remove and replace the battery to see if it caused the issue.
Tip: Before working on a hard-wired smoke detector, turn off the main power at your circuit breaker to avoid electrical shock.
Will a smoke alarm eventually stop chirping? A smoke alarm will eventually stop chirping if it stops detecting smoke or if the condition that created the false alarm is fixed. For example, if dust and debris is causing your alarm to sound, cleaning it will stop it from chirping.
If you have a battery-powered smoke alarm, it will chirp for about a month before the battery dies. But if it's a hard-wired alarm with both AC power and a backup battery, it will keep chirping until you replace the backup battery.
The alarm is low on battery. This is the most common cause of beeping alarms. The alarm will beep every 30 to 40 seconds to alert you that the battery needs to be replaced. To fix this problem, you need to replace the battery with a new one of the same type and size.
Low Battery or End-of-Life: This type of chirp indicates it is time to replace your smoke alarm's batteries or the smoke alarm itself.
There are a few possible causes for your smoke alarm to keep chirping even with a new battery. It might be time to buy a new detector. Check the date of manufacture printed on the back of your alarm to confirm it's not expired. Most alarms expire 7-10 years after the manufacture date.
'Low battery chirp' is a short high pitched warning sounds emitted by your smoke alarm every 30-40 seconds. Pressing the 'Hush' button will force the alarm into 'low battery hush' mode, temporarily silencing the low battery warning for 8 hours, to give you time to replace the 9V battery.
Remove the “Residual Charge” in Your Device
If you've replaced the batteries in your smoke detector but are still hearing those persistent beeps, your device may still have what's called a residual charge.
Lithium operated alarms are non-replaceable as the battery is sealed. However, as lithium batteries have a 10-year life span, the battery will unlikely need replacing for the entire duration of the alarm's life. Hard wired smoke alarms are mains-powered and include a battery as a backup in case of a power failure.
Green and red LED lights that indicate normal operation and alarm status o Green Light: The green LED will flash every 30 seconds to indicate the unit is operating properly.
10. Can the Fire Department come out and change the batteries on my smoke detector? Yes, if the smoke alarm is too high for the resident to reach and they are disabled or elderly and are not able to climb on a ladder to replace the batteries.
