Why do hardwired smoke detectors need batteries? Because hardwired smoke alarms are connected to the power supply, they will sound indefinitely until they are turned off. They often have battery backups to ensure they continue in the event the power supply is cut as well.
Why is my hard wired smoke detector beeping no battery?
- Turn the power off to the hard wired smoke detector at the circuit box.
- Remove the face of the alarm
- Use a vacuum or a small brush to clean out the smoke detector
- If there’s a lot of dust build up, try using a mild detergent to help remove it.
- Replace the face of the detector and listen for the chirping sound
Will hardwired smoke detectors work without battery?
Without the battery, neither of these units has the power to go off. Other smoke detectors get hardwired, meaning they tap into and draw their power from the home or building's electricity. Hardwired alarms often have a battery backup just in case the electrical power goes out.

If you live in a house with hardwired smoke detectors it decreases your risk of dying in a fire by 50%. Unfortunately, we often hear that people die in a fire because there were no working batteries in the fire alarm.
Types of Smoke Detector
The smoke detector consists of two ionization chambers, with one open to the air. An electrical charge on the ions allows a current between the chambers. This is what detects the smoke when there is a fire in your house.
Differences in Detectors
The Canadian Fire Alarm Association says that an ionization alarm is best at detecting fires with smaller particles and flames. The sort of fire that may start in your home if the kids are playing with a lighter or matches. While the photoelectric smoke detector responds to smoldering fires where a high airflow may be present.
