A 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 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.
