Fire sprinkler system
First Claim
1. A fire sprinkler system comprising:
- a plurality of sprinkler heads disposed at pre-selected locations in a structure;
means for delivering water from a main supply line to the plurality of sprinkler heads;
means for selectively isolating water in the system from water in the main supply line;
means for relieving a water pressure in the system so that the water pressure in the system is less than a water pressure in the main supply line, when the water in the system is isolated from the water in the main supply line; and
means for triggering a release of water from the main supply line to the system in response to heat generated by a fire in the structure.

Abstract
A fire sprinkler system includes a plurality of sprinkler heads disposed at predetermined positions within a structure. Water in the system, on the system side, is isolated by a solenoid-activated valve from water on the municipal or street side. The water pressure on the system side is maintained at a lower pressure than the water pressure on the municipal side. In one embodiment, the sprinkler heads include a sprinkler head casing mated with a cover plate. The cover plate separates from the casing at a specified temperature. A switch compressed between the casing and the cover plate is activated by the separation of the cover plate. Activation of the switch opens the solenoid-activated valve of the fire sprinkler system, thereby releasing water at street pressure into the system.

6. A fire sprinkler system comprising:
-
a plurality of sprinkler heads disposed at pre-selected locations in a structure;
piping for delivering water to the plurality of sprinkler heads;
an isolation valve positioned between the piping and a main supply line, for selectively isolating water in the main supply line from water in the system;
a pressure control mechanism for controlling water pressure in the system, wherein the water pressure in the system is less than water pressure in the main supply line, when the water in the main supply line is isolated from the water in the system; and
a release mechanism for triggering a release of water from the main supply line into the system in response to heat generated by a fire in the structure. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method for extinguishing a fire in a structure, comprising:
-
charging a fire extinguishing system in the structure with water;
selectively isolating water in the fire extinguishing system from water in a main supply line;
maintaining water pressure in the fire extinguishing system at a predetermined value which is less than water pressure in the main supply line; and
releasing water from the main supply line into the fire extinguishing system in response to heat generated by a fire in the structure. - View Dependent Claims (15, 16, 17, 18)

19. A method for extinguishing a fire in a structure, comprising:
-
charging a fire extinguishing system in the structure with a fire suppression agent, wherein a static pressure of the fire suppression agent in the fire extinguishing system is less than a static pressure of fire suppression agent in a main supply line;
selectively isolating the fire suppression agent in the fire extinguishing system from the fire suppression agent in the main supply line;
maintaining the static pressure of the fire suppression agent in the fire extinguishing system at a predetermined value; and
releasing fire suppression agent from the main supply line into the fire extinguishing system in response to heat generated by a fire in the structure. - View Dependent Claims (20)
