Abstract
A security system in which fire or intrusion signals may be impressed on a first and a second monostable oscillator connected in timing circuits, the first monostable oscillator producing an output for a first limited time period to excite an alarm, and coincidently in time a second monostable oscillator producing an output of shorter second time period for delaying actuation of the alarm to permit the operator to deactivate the unit prior to actuation of the alarm, each of the monostable oscillators using an integrated circuit and being reset by application of power to the unit and during function key switch position change. The fire channel has top priority over any other functional characteristics of the master control.
