Abstract
A bolting mechanism includes bolt members driven between extended and retracted configurations, a first drive train to couple motion of a handle to the members to drive them between configurations, a primary deadbolt mechanism to prevent the bolt members from being driven between configurations when the mechanism is in a locked state, the mechanism includes a fail-secure actuator that prevents the bolt members from being driven between configurations in case of power loss, a second drive train to couple motion of a second handle to the bolt members to drive them between configurations, the second drive to override the mechanism to drive the bolt members between configurations even when the mechanism is in the locked state, and a secondary deadbolt mechanism arranged to prevent the bolt members from being driven between configurations when the secondary deadbolt mechanism is in a locked state.
