A system and method for maintaining the integrity of a dry pipe sprinkler system. The system can includes an auxiliary drain including a main collection pipe, a heater having a bracket configured to attach the heater to the main collection pipe of the auxiliary drain, the bracket including a deflector configured to direct heat from the heater onto the main collection pipe, and a self-draining apparatus configured to receive excess water from the auxiliary drain.

Prefabricated wall panels simplify the constructive of building units and other structures. The prefabricated wall panels can include a set of conduits pre-installed within the wall panels that enable simplified installation and conduit routing within a building unit or structure. The set of conduits can include electrical conduit, plumbing conduit, HVAC conduit, networking conduit, fire alarm conduit, and fire sprinkler conduit. The prefabricated wall panels can include above-door cavities to assist with structure design and coupling conduits between prefabricated panels. The prefabricated panels can additionally include dual-headed fire sprinklers that enable one fire sprinkler conduit to spray into multiple rooms, reducing the overall number of fire sprinkler conduits required within a structure.

An apparatus and method for maintaining integrity of a dry pipe sprinkler system. The apparatus includes an auxiliary drain, the auxiliary drain including an input pipe, a condensate collection area, and a drain pipe; an insulated housing with a door configured to provide a heat controlled environment for the auxiliary drain, and wherein the auxiliary drain is at least partially located within the housing, and the condensation collection area is located within the housing; a heater configured to heat the housing; and an auxiliary drain alarm configured to provide a warning when the auxiliary drain retains a predetermined amount of condensate.

A pilot actuator for controlling the operation of a control valve. The control valve can be part of a thy-type fire suppression sprinkler system in which the sprinkler piping network is filled with pressurized gas such as, for example, air, nitrogen, or another gas. The pilot actuator is a differential valve that actuates the control valve when the gas pressure in the sprinkler piping network is at or below a value for tripping or actuating the pilot valve to the open position. The actuator assembly defines a neutral chamber that is at an intermediate pressure in comparison to pressures at the inlet port and the measuring port when the pilot actuator is in a stand-by state.

Systems, apparatuses, and methods of assembly of a dry pipe manifold assembly. The dry pipe manifold assembly including a lower plate and an upper plate fixed to the lower plate creating a water passage with a series of ports. The assembly further including a dry pipe actuator, manual reset actuator sub-assembly, manual trip valve, and alarm test sub-assembly fixed to the upper plate. The assembly allowing for fluid flow between the dry pipe actuator, manual reset actuator sub-assembly, and manual trip valve through the water

A control device for operating a fire extinguisher system includes at least one hose (3) having an extinguisher nozzle (4) arranged at the end of the hose (3) to be operated by an operator for releasing a pressurized extinguishing fluid. A conveying pump (5) conveys the pressurized extinguishing fluid in the hose (3) towards the extinguisher nozzle (4). A first supply line (7) connects the conveying pump (5) to a tank (8) of a fire extinguisher device, such as a fire extinguisher vehicle (1). A second supply line (9) connects the conveying pump (5) to a stationary extinguishing fluid source (2). A multi-port switch valve (10) connects upstream of the conveying pump (5), proximate the first supply line (7) and second supply line (9).
