Abstract
An apparatus for use in a multi-purpose piping system that provides water to both domestic uses and to fire sprinklers, the apparatus comprising: piping having an inlet and an outlet; a detector, located between the inlet and outlet, that distinguishes between a fire sprinkler water flow and a domestic use water flow; and a drain connection located between the inlet and the outlet. A multipurpose piping system using the apparatus in a system incorporating at least one fire sprinkler, the piping system also supplying at least one other use in the structure.
Claims36
An apparatus for use in a multi-purpose piping system that provides water to both domestic uses and to fire sprinklers, the apparatus comprising:
- a. piping having an inlet and an outlet;
- b. a detector, located between the inlet and outlet, that distinguishes between a fire sprinkler water flow and a domestic use water flow;
- c. a drain connection located between the inlet and the outlet.
An apparatus for use in a multi-purpose piping system that provides water to both domestic uses and to fire sprinklers, the apparatus comprising:
- a. piping having an inlet and an outlet;
- b. a means, located between the inlet and outlet, for distinguishing between a fire sprinkler water flow and a domestic use water flow;
- c. a drain connection located between the inlet and the outlet.
An apparatus for use in an open multi-purpose residential fire sprinkler and domestic water system, the apparatus comprising:
- a. a conduit having an inlet and an outlet;
- b. means for distinguishing between a fire sprinkler flow and a domestic flow through the conduit in the open system and sending an alarm signal when flow exceeds domestic use water flow;
- c. a pressure gauge that measures the pressure in the conduit;
- and
- d. a drain connection in fluid communication with the conduit.
A method of detecting a fire sprinkler flow in a multi-purpose residential fire sprinkler and domestic use system, the system having common piping for the fire sprinkler and domestic use, the method comprising:
- a. providing an apparatus having—
- i. piping having an inlet and an outlet;
- ii. a flow detector, located between the inlet and outlet, that distinguishes between a fire sprinkler water flow and a domestic use water flow;
- and
- b. calibrating the apparatus to distinguish between fire sprinkler, water flow and a domestic use water flow.
An apparatus, comprising:
- a. a pipe of a multipurpose piping system having an interior passage through the pipe directing a flow through the pipe;
- and
- b. a detector communicating with the interior passage of the pipe, the detector having a non-alarm condition when the flow is less than a maximum domestic flow and an alarm condition when the flow is greater than a maximum domestic flow.
