The present technology provides a bi-directional control valve for a fire suppression system. In particular, this bi-directional control valve comprises an inlet, a first fluid communication passageway or outlet (port) and a second fluid communication passageway or outlet (port). The first outlet port is configured to be connected to a detector tube as part of a direct system and the second outlet port is configured to be connected to a discharge tube as part of an indirect system. The detector tube comprises a heat sensitive tube suitably configured to rupture or otherwise lose integrity as a result of exposure to heat associated with exposure to a fire condition. As a result of this rupture, a pressure contained within the detector tube will be released and then acts as a signal to actuate the bi-directional control valve such that the fire extinguishant contained within a cylinder is simultaneously released through the detector tube and the discharge tube. |
