12. A utilities control system comprising:
-
a wall-mounted, DC powered control system located within a building or room and comprising in electronic communication an occupant activation device, a seismic sensor and a wireless transmitter; one or more utilities shut-off devices each in electronic communication with a wireless receiver; wherein said occupant activation device comprises the combination of a light transmitter, a light detector, a slotted card receiver and a removable light blocking member positionable within said slotted card receiver to prevent light from said light transmitter from reaching said light detector, whereby insertion of said light blocking member into said slotted card receiver sends a signal from said wireless transmitter to said one or more wireless receivers to allow utilities to be delivered and whereby removal of said light blocking member from said slotted card receiver sends a signal from said wireless transmitter to said one or more wireless receivers to activate said utilities shut-off device to stop delivery of said utilities; and further whereby upon the sensing of a seismic event by said seismic sensor, a signal is transmitted from said wireless transmitter to said one or more wireless receivers to activate said utilities shut-off device to stop delivery of said utilities even if said light blocking member is positioned within said slotted card receiver. - View Dependent Claims (13, 14, 15)
