Abstract: A supervised fire suppression system (10, 100) is disclosed that includes a discharge valve (14, 114) for controlling release of a fire extinguishing agent from a container (12), a control head (16, 116) operatively associated with the discharge valve for actuating the discharge valve in the event of a fire, wherein the control head may be removed from the discharge valve to facilitate inspection of the control head, and an internal supervisory switching device (130) mounted within the control head and configured to interact with the discharge valve to provide an indication that the control head has been removed from the discharge valve.

Abstract: A vehicle includes a body, a door, an actuator, and a controller. The body includes an upper portion, a lower portion and a pillar member. The actuator is coupled with the pillar member and includes a movable member that is movable between deployed and retracted positions. The controller is electrically coupled with the actuator and is configured to facilitate movement of the actuator from the retracted position to the deployed position in response to detection of a collision. When the movable member is in the deployed position with the door closed, the movable member is in an abutting relationship with the door. When the movable member is in the retracted position, the movable member is spaced from the door.
