Increase home safety with a vast selection of smoke detectors to sense fires, CO2, and CO before becoming a major problem. Detectors contain 10-year sealed batteries for permanent power and protection in the event of a power outage. Our AC/DC powered detectors come with voice messaging systems to notify homeowners when to replace batteries. Ionization technology detects invisible fire particles quicker than photoelectric alarms.
