Safe Family Life Magnetic Door Alarm With Disarm Key

This compact magnetic door alarm uses magnetic contact to trigger a loud siren whenever a protected door or window is opened. A disarm key, rather than a simple switch, keeps the alarm from being easily turned off, making it well suited for entry doors and sliding glass doors.

• Brand: Safety Technology (Safe Family Life)
• 110 decibel siren
• Magnetic base and actuator design
• Disarm key prevents easy deactivation
• Runs on three lithium button cell batteries (included)
