ABSTRACT:
A system and method for temporarily disabling a smoke detector alarm unit. The present invention includes a switch between the main assembly and the power assembly of the unit and a timer for monitoring a predetermined length of time. The switch is caused to break the circuit between the main assembly and the power assembly while the timer monitors the passage of time. Once the predetermined length of time has passed, the switch is caused to reengage the circuit between the main assembly and the power assembly.
