I'm in need of a reliable electrician to fix our smoke detectors. They are hard wired and beeping! We can't figure out how to make them stop. If you unplug it, Something inside the ceiling beeps!

Most hardwired smoke alarms have a 9 v battery. This allows the alarm to operate if power is lost. The alarms have a flip cover or a slide out cover to change the battery. Feel free to give me a call if you have any additional questions. Scott 360 Electric 3093395946
