How does it work?
By definition, an automatic fire suppression system can operate without human intervention. To do so it must possess a means of detection, actuation and delivery.
In many systems, detection is accomplished by mechanical or electrical means. Mechanical detection uses fusible-link or thermo-bulb detectors. These detectors are designed to separate at a specific temperature and release tension on a release mechanism. Electrical detection uses heat detectors equipped with self-restoring, normally-open contacts which close when a predetermined temperature is reached. Delivery is accomplished by means of piping and nozzles. Nozzle design is specific to the agent used and coverage desired. Remote and local manual operation is also possible.
