Abstract

A residential dwelling unit fire protection system for a residential dwelling unit (R). The fire protection system includes a pressurized liquid supply (10), a pressurized gas supply (28), a control valve (30) coupled to the liquid and gas supplies, the control valve (30) being biased in a closed position to prevent liquid flow through the control valve (30) based on a pressure differential between the liquid and gas supplies, a network of pipes (22, 22a, 22b, 23) coupled to the pressurized gas supply (28), a minimum quantity of residential fire sprinklers (40A, 40B, 40C), and an alarm (38) to indicate a flow of liquid through the network. Each of the quantity of residential fire sprinklers is coupled to the at least one pipe so that, upon actuation of at least one residential fire sprinkler, the control valve (30) is actuated to deliver liquid from the liquid supply (10) to at least one of the residential fire sprinklers for distribution over a protection area (A) at a predetermined density in at least one compartment.

Description

technical field

[0001] Automatic sprinkler systems are one of the most widely used fire protection equipment. These systems have sprinklers that are activated whenever the ambient temperature in an environment such as a room or building rises above a predetermined value. Once activated, the sprinklers dispense a extinguishing fluid, preferably water, within a room or building. A sprinkler system, depending on its particular construction, is considered effective if it can contain or suppress a fire. When these systems are deactivated during building renovation or decommissioning, the system may fail, or the danger of occupancy has increased beyond the original system effectiveness.

[0002] The sprinkler system is provided with a water source (eg, a storage tank or municipal water supply). This water source may be separate from the fire service water supply. Regardless of the water source, the sprinkler system is provided with a line into the building to provide a riser. C...
