Smoke detectors are considered to be “hard-wired” if they are connected to the household electrical system. These detectors may or may not have battery backup. These types of smoke detectors should be tested at least once a month. Notify your Home Security Monitoring Service before testing if your “hard-wired” smoke detector is connected to your home security system.
If a “hard-wired” smoke detector needs to be replaced, homeowners should contact a licensed electrician, as the Bedford Fire Department does not handle changing out these types of detectors.
