ABSTRACT:
A security system of the type wherein the occurrence of a monitored event, such as presence or motion of an individual at a first location, triggers an alarm at a second location. The invention provides a means of disabling the alarm during times when the device is subject to repeated actuation under conditions when the cause of the repeated actuation is know, as when workmen are present in the monitored location. An infrared sensor causes an RF transmitter to send a signal to a receiver. Switch means interposed between the receiver and alarm device have first and second states wherein the alarm-actuating signal from the receiver is passed and blocked, respectively, to the alarm. A push button is selectively operable to change the state of the switch means from the first to the second, whereby pressing the button effectively disables the alarm. A pulses counter or other such timing means is actuated by pressing the push button and establishes a time period at the conclusion of which the switch means is changed back to its first state, thereby again enabling the alarm device.
