A thermal trigger assembly for remote mechanical actuation of another fire protection system component includes an activation component having a base and a movable member. A bias member biases the movable member from a preactivation to an activated position with respect to the base. A thermally responsive element retains the movable member in the preactivation position until a predetermined thermodynamic condition is reached, when the thermally responsive element loses structural integrity. A flexible connector includes a flexible hollow outer cable housing with one end configured to be stationarily (preferably fixedly) connected with the base. A flexible cable is inside the outer cable housing for sliding movement therein and has one end configured to be stationarily (preferably fixedly) connected with the movable member. The flexible cable is moved with respect to the outer cable housing by movement of the movable member upon loss of structural integrity by the thermally responsive element.

A network-type temperature-controlled hanging extinguishing system includes: a main fire-fighting pipe which has at least one fire-extinguishing medium support port; at least one fire-extinguishing medium pressure bearing tank communicated with the main fire-fighting pipe; at least one fire sprinkler valve which is communicated with the main fire-fighting pipe and includes a memory alloy part adapted for controlling opening and closing a valve body; and at least open nozzle which is communicated with the fire sprinkler valve, such that when the fire sprinkler valve is opened, the fire-extinguishing medium is sprayed, and when the fire sprinkler valve is closed, the fire-extinguishing medium is stopped spraying. An amount of the fire-extinguishing medium pressure bearing tanks is different from that of the open nozzles; a user is able to select an appropriate amount of fire-extinguishing medium pressure bearing tanks as required to reduce the manufacturing, assembly and maintenance cost of the entire system.
