ABSTRACT:
Disclosed is a safety lockout system for battery powered smoke alarms. The body of the smoke alarm is removably securable to a mounting bracket that is attached to the wall or ceiling of a building. The safety lockout system prevents securing the body of the smoke alarm to the mounting bracket prior to the installation of a battery. Once a battery is installed in the body of the smoke alarm, it may easily be secured to the mounting bracket attached to the wall or ceiling.
