Patent number: 9032994Abstract: 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.Type: GrantFiled: April 23, 2012Date of Patent: May 19, 2015Assignee: AGF MANUFACTURING, INC.Inventors: James P.

Patent number: 7836966Abstract: An arrangement for testing a fire suppression sprinkler system includes a conduit for supplying a flow of fire suppression fluid to at least one sprinkler. A sensor is configured to sense the flow of the fire suppression fluid to the at least one sprinkler. The sensor has a first condition indicative of a predetermined volume of flow of the suppression fluid to the at least one sprinkler and a second condition indicative of a volume of flow of the fire suppression fluid to the at least one sprinkler less than the predetermined volume of flow. An actuator causes the sensor to be in the first condition or the second condition. A signaler provides an indication to a user that the sensor is in at least one of the first condition and the second condition.Type: GrantFiled: January 28, 2008Date of Patent: November 23, 2010Assignee: AGF Manufacturing, Inc.Inventors: George J.
