Abstract
A hazard control system according to various aspects of the present invention is configured to deliver a control material in response to detection of a hazard and signal a secondary hazard detection system that an event has occurred. In one embodiment, the hazard control system comprises a pressure tube having an internal pressure that is configured to leak in response to exposure to heat. The leak changes the internal pressure and generates a pneumatic signal. A valve may be coupled to the pressure tube and be configured to release the control material from a container is response to the pneumatic signal. A second valve may also be coupled to the pressure tube and be configured to provide a signal to the secondary hazard detection system in response to the pneumatic signal.
