US 2007/0176766 A1 · Remote controlled smoke alarm with timer

Abstract

A smoke detector system wherein a smoke alarm which is turned “on” by the sensing of smoke is turned “off” for a predetermined period of time using a disable signal transmitted by a remote controller and an indicator light is turned “on” to indicate that the alarm is turned “off”, and wherein after the predetermined period of time, the alarm is returned to a normal state and the indicator light is turned off. Thus, when the smoke detector alarm is turned “on” by an erroneous or non-lethal sensing of smoke, a housekeeper can readily turn “off” the alarm for the predetermined period of time and see by the indicator light that the alarm is off for that period of time. Advantageously, the remote controller comprises a container having a permanent magnet and the remote controller is physically apart from the detector so that the controller can be conveniently stored, for example on a refrigerator door for quick use and storage.

An alarm system which emits a warning sound upon detection of an undesired factor in the environment, said system comprising in combination:

an alarm means comprising at least one alarm unit having an alarm, energizing means for powering said alarm, sensor means for detecting said undesired factor and for causing said alarm to operate, switching means for causing disabling of said energizing means from powering said alarm, and timer means for causing said switching means to reconnect said energizing means to said alarm after a preset duration of time, and an indicator means operable when said alarm is disabled and being turned off when said alarm is returned to a normal mode;
and
remote control means which is physically unconnected to said alarm means for emitting a disable signal which is received by said switching means in said alarm means to cause disabling of said alarm and to cause operation of said timer means in said alarm means and concurrent operation of said indicator means.
