A pendent fire protection sprinkler includes a sprinkler body having an inlet and an outlet that define a fluid passage and a sprinkler axis, a pair of frame arms that form a junction, a plug that seals the fluid passage, and a thermally responsive element provided between the plug and the junction, and configured to maintain the plug in the fluid passage prior to actuation of the sprinkler. A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first angled portion, a second angled portion, a third angled portion, and a fourth angled portion, each angled portion extending outwardly from the planar central portion. Each of the first to fourth angled portions is bent away from the frame arms in the outlet direction from the plane of the planar central portion.

A deflector, mounted to the junction, includes an annular, planar central portion extending along a plane that is perpendicular to the sprinkler axis, as well as a first portion, a second portion, a third portion, and a fourth portion, each portion extending outwardly from the planar central portion. Each of the first and second portions has a rounded outermost peripheral edge. Each of the third and fourth portions has first, second, and third rectilinear outermost peripheral edges, a respective second rectilinear outermost peripheral edge being located between respective first and third rectilinear outermost peripheral edges, and the first and third rectilinear outermost peripheral edges being obtusely angled relative to the respective second rectilinear outermost edge.

A pressure maintenance device is connected to a fire protection sprinkler system having downstream piping that is exposed to freezing temperatures, and supplies a pressurized fluid to the downstream piping when the sprinkler system is in an inactivated state. When an outlet pressure sensor near an outlet of the pressure maintenance device detects that a pressure of the pressurized fluid downstream of an outlet regulator falls below a first predetermined pressure, the pressure maintenance device supplies the pressurized fluid in a primary supply mode or a secondary supply mode. The pressure maintenance device automatically switches from the primary supply mode to the secondary supply mode if a supply pressure sensor detects that a pressure of the pressurized fluid downstream of a first pressurized fluid valve, and upstream of the outlet pressure regulator, falls below a second predetermined pressure.

A horizontal sidewall fire protection sprinkler includes a sprinkler body, a sealing assembly, a sleeve body, a yoke, a load screw, levers, a soldered link, a slide plate, a deflector support member, a deflector, and a spring. When ambient temperature in an occupancy reaches a predetermined temperature, the soldered link fails, the levers release, and the yoke and the load screw are forced away from the sprinkler body. The spring forces the slide plate and the deflector support member away from an inner wall of the sprinkler body toward an opening at an outer end of the sleeve body, and the deflector support member and the deflector protrude from the outer end of the sleeve body. The sealing assembly is released from a sealed state, and the fire protection sprinkler outputs fluid from a fluid supply to the occupancy.

A fire protection sprinkler is provided. The sprinkler includes a body having an output orifice and a flange; a seal cap to seal a flow of fluid from the output orifice; and a thermally-responsive element positioned to releasably retain the seal cap and constructed to separate into a plurality of portions upon exposure to a predetermined temperature. The sprinkler also includes at least one deflector support member, a deflector connected to the deflector support member, and at least one arm extending from each of the deflector support members. Each of the arms has a free end positioned in spaced relation to the thermally-responsive element to contact the portions of the thermally-responsive element upon separation thereof. In another embodiment, the sprinkler includes at least one arm extending from the flange, and the arms may be formed as a bracket.
