An additive supply system for a fire fighting mechanism comprises an additive supply line connecting an additive source to a fire fighting fluid line, the additive supply line being in fluid communication with an additive pump and a recirculating line; a balanced pressure valve capable of throttling the recirculating line; and a control means for controlling the additive pump based on one or more of a high pressure outputted by a high pressure sensor, a low pressure outputted by a low pressure sensor, an additive pump displacement outputted by an additive pump controller, a fire fighting fluid pressure outputted by a fire fighting fluid pressure sensor and an additive pressure outputted by an additive pressure sensor is disclosed. Methods of using the additive supply system are also disclosed.

A sprinkler includes a body including an internal passageway extending from an inlet to an orifice. The body can be made of a composite material, such as a polymeric material. The sprinkler can include a first frame arm extending from the body, a second frame arm extending from the body, and a connector member connecting the first frame arm with the second frame arm.

Systems and apparatuses of a sprinkler frame having an upper section, a lower section, and a channel extending along a sprinkler axis are provided. The lower section can include apertures through the frame, a guide pin having a first end with a head, a second end, and a shaft extending therebetween. The shaft of the guide pin can translate in an axial direction of the sprinkler axis within the apertures of the sprinkler frame. The deflector can couple with the second end of the guide pin and can include a first side, second side, third side, and fourth side. The first side and the second side may be smaller than the third side and the fourth side and can include an end profile defining a first tine, second tine, third tine, and fourth tine separating a first slot, second slot, and third slot.

A sprinkler assembly includes a body defining an inlet, an outlet, and a fluid passage extending along a longitudinal axis between the inlet and the outlet. A guide pin aperture is defined by at least one of the body or a bushing coupled to the body. The sprinkler assembly further includes a deflector slidably coupled to the body. The deflector includes a deflector body coupled to a guide pin. The guide pin includes a shaft portion extending through the guide pin aperture and a shoulder that is wider than the shaft portion and configured to engage at least one of the body or the bushing to limit movement of the deflector body away from the body.

A sprinkler includes a connector, a body, at least one pin, and a deflector. The connector extends between an inlet end and an outlet end. The body includes a pin wall extending from the outlet end of the connector. The pin wall defines at least one pin receiver. The body wall extends from the pin wall. The pin wall and the body wall define a chamber. The at least one pin is fixed with the at least one pin receiver. The deflector is coupled with the at least one pin to move within the chamber along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state.

At least one aspect is directed to a device to configure a fire sprinkler. The device can have an elongated member. The elongated member can have an open end, an opposing closed end, and a body extending laterally therebetween. The open end can receive a portion of a fire sprinkler. The closed end can have a main aperture. The main aperture can receive a portion of a ratcheting socket wrench drive. The closed end can have at least one surrounding aperture. The surrounding aperture can be positioned apart from the main aperture to define a solid partition therebetween. The solid partition can have non-uniform thickness between the main aperture and the at least one surrounding aperture.

At least one aspect is directed to a removable sprinkler protection device. The removable sprinkler protection device can include a foldable unitary member. The foldable unitary member can include a first portion having a first extension, a second extension, a third extension, or a fourth extension. The foldable unitary member can include a second portion having a fifth extension, a sixth extension, or a seventh extension. The fourth extension can be disposed at least partially between the first portion and the second portion. The seventh extension can include a tab. The first portion or the second portion can include an opening. The foldable unitary member can be made from at least partially of a biodegradable material.

Systems, methods, and devices related to mixing foam fire suppressant are provided. A foam proportional mixing device includes a first pump. The first pump includes an inlet pipe coupled with a first housing, such that the inlet pipe is in fluid communication with a first cavity defined by the first housing. The first pump includes a foam receiving port arranged on the inlet pipe and a pair of rotors positioned within the first housing. The foam proportional mixing device includes a second pump. The second pump includes a pair of gears located within a second cavity defined by a second housing. The foam receiving port is in communication with an outlet of the second pump, such that the first pump is in fluid communication with the first cavity.

A nozzle includes an inlet end having one or more inlet apertures and an outlet end having one or more outlet apertures. The nozzle includes a body member that extends between the inlet end and the outlet end. In some embodiments, the nozzle includes a central member that extends centrally through the body member. The nozzle includes an end member fixedly coupled with the central member at the outlet end. The nozzle includes a slidable member translatably coupled with the central member. The slidable member is configured to direct fluid that flows through the body member outwards towards an inner surface of the body member and translation of the slidable member adjusts a K-factor of the nozzle.

A modular storage tank assembly including a body defining an internal volume structured to hold a fire suppression agent. The body including multiple planar side portions defining the internal volume, at least one body inlet aperture, and at least one body outlet aperture. The modular storage tank assembly also including a case. The case including a case body, a first flange on a first side of the case body and a second flange on a second side of the case body, at least one case inlet aperture, and at least one case outlet aperture.
