Abstract:
A deterrent system adapted for use with one or more sprinkler devices, said system comprising:a detector configured to generate an intruder detection signal when an intruder is detected within an area to be protected from intrusion; and a control circuit for generating a sprinkler activation signal, said sprinkler activation signal being used to control one or more water flow valves associated with the sprinkler devices, such that said control circuit causes the sprinkler devices to spray water into said area in response to said intruder detection signal; and said control circuit further including a voltage regulator adapted to operate with an operating voltage taken from a low voltage AC supply system and a low voltage DC supply system and which voltage regulator compensates for variations in such supply system; wherein said operating voltage is substantially below 110 volts, and said operating voltage can vary by more than a factor of two.
