what is a fire system accelerator
Abstract: A dry accelerator (1) for use in a dry, pressurized-gas, liquid sprinkler fire control and suppression system, that is response-sensitive to a decay in gas pressure in the system, caused by a system-triggering event, is disclosed.he dry accelerator is actuated to in turn accelerate the actuation of at least one other device in the system that controls the release of a liquid fire-extinguent. The dry accelerator generally includes a housing with two gas chambers (3, 4) therein, separated by a diaphragm.
