Types of smoke alarms

  • Battery alarms run on a battery. They need new batteries when they chirp.
  • Hardwired alarms connect to your home's electrical system. Most also have a battery backup for power outages.
  • Interconnected alarms sound together, so an alarm on one level of your home is heard on the others.
  • Combination smoke and carbon monoxide alarms do both jobs in one unit.

We install hardwired and interconnected smoke and CO alarms, and CO alarms on their own. Tell us what you have and what you need when you call.
