Abstract
Apparatus for disabling an alarm after a predetermined operating period employs a relay which is operated by a gate circuit. A contact of the relay applies operating potential to an alarm. An oscillator energizes a counter circuit and after a predetermined selectable period, the counter circuit inactivates the relay via the gate to cease alarm operation.
