Designed to be wired directly into home's electrical system, features a backup battery that helps keep the alarm functioning even in the event of a power outage. Battery life varies according to use and application. Gasket-less mount helps ensure a perfect alignment for easy installation, while tamper-resistant locking pins keep the alarm secure.
