Abstract
Abstract An alarm control system has an internal receiver module and an internal ultrasonic intruder detector module connected to one input channel of a bistable flip-flop. An internal heat sensor fire detector is connected to another input channel. Remote inputs are connectable to either input channel. Inputs in the first channel cause the flip-flop to change to the alarm state and to operate a relay driver which partially completes AC outlet relays and remote output relays and which starts an adjustable delay timer to operate a second relay driver for partially completing a horn relay and for partially completing a circuit to a reset delay device. A function selector selectively grounds one or more of the output relays preparatory to operation of the flip-flop and relay drivers so that the circuits are ready to operate the appropriate output when the flip-flop is biased into an alarm state. The second channel is connected directly to the second relay driver and to the function selector for overriding the function selector for grounding all relay coils so that all signals operate when an extremely hazardous condition such as fire is sensed by second channel sensors.
