Abstract: An arrangement for testing a fire suppression sprinkler system includes a supply conduit for supplying a fire suppression fluid to a plurality of sprinklers. A sensor senses a flow of fire suppression fluid through the supply conduit. A drain conduit drains fire suppression fluid when the fire suppression system is tested. A drain valve controls the flow of the fire suppression fluid so that when the fire suppression system is tested the fire suppression fluid is controlled to enter the drain conduit. A fire suppression fluid collection tank collects the fire suppression fluid which has entered the drain conduit for reintroducing the collected fire suppression fluid to the supply conduit. A circulation valve controls the flow of the fire suppression fluid so that when the fire suppression system is tested the fire suppression fluid enters the fire suppression fluid collection tank.
Abstract: A method for activating a sprinkler system comprises maintaining a liquid extinguishant in system pipes under a standby pressure that is less than the operating pressure, determining an arrangement of the sprinklers that will control a fire, and opening the sprinkler system valve in response to a drop in pressure in each of the pipes to which at least one of the sprinklers of the arrangement is connected. An alternate method comprises providing a bypass around the system valve, and opening the system valve in response to (1) a predetermined flow of liquid extinguishant through the bypass and (2) a drop in pressure in the sprinkler system below a predetermined pressure. In a variation of the alternate method, the system valve is opened in response only to a predetermined flow of liquid extinguishant through the bypass.

Abstract: A security disposition against fire applicable for delaying, retaining, controlling and extinguishing the action of fire by means of moisture, with water as its basic extinguishing element. It consists of a part that is made of metal or any other material with identical resistance, upon which water distribution pipes are placed, and is equipped with distributors that have access to the partition or similar construction. The distribution pipes are joined by connecting piping, which at the same time is connected to a supply pipe. On the connecting piping, between the supply pipe and the distribution pipes, is an open/close electrovalve that is activated by conventional fire detecting methods, temperature or smoke, in addition to a purge valve that is activated manually.
Abstract: An accelerator for venting a pressurized gas source to the ambient is disclosed. The accelerator includes a first gas compartment connected to the pressurized gas source. A second gas compartment is connected to the first gas compartment through a one-way valve allowing gas to pass from the first gas compartment to the second gas compartment. A restrictor orifice allows gas to pass between the first and the second gas compartments at a predetermined rate. A valve member in the first gas compartment is normally in the closed position and moves to the open position in response to a pressure drop of the pressurized gas source causing a pressure differential between the first and second gas compartments, thereby venting the pressurized gas source to the ambient through the valve member in the first gas compartment.
Abstract: A pneumatic actuator having AND gate logic characteristics is disclosed. The actuator has three chambers each divided into two chamber portions by respective flexible diaphragms. One of the diaphragms acts as a valve closing member and controls the flow of a pressurized fluid through the actuator to actuate an associated device when fluid flow is permitted. The other two diaphragms are in mechanical contact with one another and in hydraulic communication with the one diaphragm and thereby control its motion, keeping it normally closed and preventing fluid flow but allowing it to move into an open position permitting fluid flow and actuation of the associated device only when each of the two diaphragms are subject to separate, concurrent drops in pressure which allows both of them to deflect away from the one diaphragm.
Abstract: Embodiments of a low-pressure actuator, for use in a dry, low-pressure, pressurized gas, liquid fire control and suppression sprinkler system, with a pneumatic/electric double interlock mechanism, which requires that two separate events, such as discharging air pressure from the sprinkler system, and an electrical detection, must occur in order for the sprinkler check valve to be activated, thereby allowing water into the sprinkler system, are disclosed. In certain embodiments, a low-pressure actuator is utilized in series with a liquid flow valve equipped with a solenoid and an electrical detector/sensor for detecting an event such as the occurrence of smoke, heat, or a high rate of temperature rise. In alternative embodiments, the low-pressure actuator itself is equipped with the solenoid and detector/sensor.
