ABSTRACT:
An alarm clock system consisting of a clock with a local alarm circuit and provided with a remotely located turn-off control device actuated by a push button switch. The local alarm system, in response to an electrical signal produced by the clock at a preset time, generates a first sound in the form of a continuous tone lasting for 40 seconds, followed by a strident pulsating sound for another 40 seconds. To turn off the alarm, the user must get out of bed, walk to the remote location, and then depress the switch push button and hold it for a predetermined time, such as 12 seconds. Actuation of the push button switch causes the remote control component to generate and transmit a radio signal, which is detected by a radio receiver in the alarm clock local component. Also, an indicating lamp on the remote component is energized and goes off after 12 seconds of continuous depression of the push button. The radio signal received by the local component causes interruption of the alarm and completely deactivates the alarm mode after 12 seconds of push button depression. If the pushbutton is released, namely, before 12 seconds, transmission of the radio signal stops and the clock alarm resumes. The push button must again be depressed to start another alarm-deactivation period. The system is arranged so that if so desired, a direct connection of the pushbutton switch alarm turn-off component can be made to the clock component, and the radio link is not used. As another alternative, the remote transmitter can be coupled to the clock radio receiver by a coaxial cable.
