Cylinder pressure switch for automatic fire protection systems

摘要

A self-contained fire protection system for an engine compartment and the like includes a gas cylinder or bottle having an outlet and a manifold secured to the cylinder. The manifold defines a through passage. Secured to the manifold is a thermally responsive actuator. The actuator includes a cap which is released in a fire condition permitting the contents of the cylinder to be discharged. A pressure switch having a pressure sensing port is mounted on the manifold. A switch activation accelerator includes an elongated stand pipe or tube extending from the pressure sensing port. The tube moves the effective position of the sensing port to an ambient pressure location.
