ABSTRACT:
An automatic water shut-off apparatus for connection to an intrusion alarm system, such as a burglar alarm, that provides for protection of a building from water damage while the alarm is armed. An electrically controlled valve, which controls water flow into the building, is closed whenever the alarm system is armed, thus preventing water damage while the building is unattended. A manual shut-off switch is also provided to close the electrically controlled valve and shut off the water when the alarm system is disarmed or for maintenance. A manual bypass valve may be provided to allow water flow into the building in the event of electrical failure.
