Clock alarm control system employing a push button alarm- deactivation switch which must be held depressed for a time period

摘要

An alarm clock with an alarm system which can be deactivated by means of either a local or remote manually operated push button switch which must be held in a depressed condition for a predetermined period of time in order to effectively deactivate the clock alarm. Means is provided to adjust the length of required switch hold-down time. An indicator is provided for showing the completion of the required hold- down period. In the case of remote deactivation, wherein the user must walk to the location of the push button switch, a radio link is employed to couple the remotely located switch with the locally positioned clock alarm system and to provide the desired alarm deactivation. The completion of the hold down period is signalled either by visual indicating means or by audible sounding means. Failure to complete the required hold-down period causes the normal audible alarm signal to be turned back on, and a new switch hold-down cycle for the required preset time period must be commenced for deactivation of the alarm. Local/remote switching circuitry is provided to allow the user to select a preferred control location for terminating an alarm cycle. The system may comprise separable modules and may include a separable standard broadcast radio receiver module.
