ABSTRACT:
Apparatus for shutting off utilities, such as gas and electricity, automatically in the case of an emergency, such as an earthquake. The utility can be a gas or electric line and, at shutdown, an alarm may be sounded and a light activated. The apparatus includes a box mounted adjacent the main power panel. The box includes a solenoid wired to the main breaker switch of the main power panel and a start/stop switch coupled to the solenoid valve at the main gas line. If an earthquake hits, the solenoid to the electric panel is activated to shut off the main switch. This in turn activates the solenoid to the gas line which turns off the gas. Simultaneously, a signal alarm coupled to the box sounds and a light also coupled to the box is lit. The alarm may be turned off manually and the light kept on, if desired. After the emergency, the control panel may be reset and the gas turned on after manually opening the gas valve and re-lighting the pilot. Power to the box may be provided by coupling the same to the main power panel. Optionally, the apparatus may also be used to shut off the main water line.
