ABSTRACT:
A seismic safety apparatus has a housing having an internal space and an external surface. A seismic safety activating mechanism is provided inside the housing for activating a seismic safety device. The seismic safety activating mechanism includes an inertia ball recess located in the internal space, an inertia ball in the housing that has an unactuated position on the recess and an actuated position displaced from the unactuated position on the recess. The inertia ball recess is formed so that when the inertia ball is in the valve member recess, vibrations or seismic shocks of a predetermined magnitude cause the inertia ball to move from the unactuated position to the actuated position. An engagement component inside the housing is provided as part of the seismic safety activating mechanism at the actuated position for engagement with the inertia ball when the inertia ball is displaced from the unactuated position. A permanent magnet is provided exterior of the housing for manually moving the inertia ball from the unactuated position to the actuated position to engage the engagement component.
