A tension indicating for a fire suppression system device is disclosed, including a body including first and second ends. At least one of the first and second ends is configured to be operatively coupled to a tensioned line of a mechanical fire detection line of a fire suppression system. The tension indicating device further includes a piston configured to be slidably disposed along a length of the body, the piston configured to be operatively coupled to the tensioned line of the mechanical fire detection line. The piston is provided with a movable indicator. Responsive to the tensioned line being provided with tension, the piston moves towards the end of the body, thereby causing the movable indicator to correspondingly move to indicate a tension in the tensioned line of the fire suppression system.

An overheat detection system comprising a controller for declaring the overheat, and two wiring connections running along a monitored system and configured to react upon overheat. The controller is configured to determine an electrical status of each wiring connection at least between operative and inoperative, the inoperative status corresponding to an electrical anomaly thereof, and electrically connect or disconnect the wiring connections depending on the electrical status thereof, wherein the declaration of overheat is based on a dynamic reconfiguration of the overheat detection system.

In an embodiment a fire extinguishing system includes a plurality of fire extinguishing injectors filled with fire extinguishing chemicals, the fire extinguishing injectors configured to be installed in a vehicle to be able to inject the fire extinguishing chemical to a tire and a fire detection line installed to connect between the plurality of fire extinguishing injectors, wherein each of the fire extinguishing injectors comprises a pressure generator in which a pressure generation chemical is installed and a tank is filled with the fire extinguishing chemical, the tank having a plurality of injection holes, wherein the fire detection line is connected to each pressure generator to generate injection pressure due to the pressure generation chemical when a fire is detected through the fire detection line, and wherein each tank is coupled to the pressure generator to allow the fire extinguishing chemical in the tank to be injected through the injection holes due to action of the injection pressure generated by the pressure generator.

An atomizer nozzle for the automatically dispensing of a liquid comprises: a main body; a dispensing head; and a locking assembly. The main body comprises: an inlet configured to be supplied with the liquid; an outlet; and a cavity extending from the inlet to the outlet. The dispensing head, movable along the cavity, is configured to dispense the liquid beyond the outlet, outside the atomizer nozzle. The locking assembly comprises a thermosensitive element configured to break at a predetermined temperature. The locking assembly is configured to: lock the dispensing head in a locked position at a distance from the outlet; and automatically release the dispensing head from the locked position when the thermosensitive element reaches the predetermined temperature. The dispensing head is further configured to move along the cavity when released, thereby reducing the distance until it is eliminated, and to dispense the liquid by protruding from the outlet.

The current disclosure describes car parking garages, water mist fire protection systems for car parking garages, methods and water mist sprinklers therefor, the car parking garage system (10) comprising a floor deck (50) and a ceiling deck (51) spaced about a longitudinal axis (A) extending parallel to the ceiling deck (51), defining an effective height range (H1) between the floor deck (50) and the ceiling (51) deck in a direction perpendicular to the longitudinal axis (A); and a fire protection system including a supply pipe system (30) having a parallel portion (31) disposed parallel to the longitudinal axis (A); and at least one water mist sprinkler (100) coupled to the parallel portion (31) of the supply pipe system (30), the at least one water mist sprinkler (100) including a frame body (110) having an inlet (111) for receipt of an extinguishing fluid from the supply pipe system (30), an outlet (113) with a passageway (112) extending between the inlet (111) and the outlet (113) to define a discharge coefficient of a nominal metric K-factor of below 32, a seal assembly (114) and a heat-responsive trigger (115) to support the seal assembly (114) in the outlet (113); and a deflector (120) coupled to the frame body (110) and spaced from the outlet (113) for distribution of the extinguishing fluid; wherein the effective height range (H1) is up to 4 meters.

A fire sprinkler head has a valve with an X-brace latch, and includes a flexible conduit. A sprinkler nozzle is secured to a first end of the flexible conduit. The sprinkler nozzle includes a first fitting, a sprinkler orifice and fusible element. A second fitting is secured to the second end of the flexible conduit and includes the valve. The valve has a valve element which is moveable from a latched position to an unlatched position. A flexible link extends from the sprinkler nozzle to the X-brace valve latch. Breaking of the fusible element releases the flexible link to move from the latched position to the unlatched position, releasing the valve for flow there-through.
