Abstract: A tension indicating for a fire suppression system device is disclosed, including a body including first and second ends. At least one of the first and second ends is configured to be operatively coupled to a tensioned line of a mechanical fire detection line of a fire suppression system. The tension indicating device further includes a piston configured to be slidably disposed along a length of the body, the piston configured to be operatively coupled to the tensioned line of the mechanical fire detection line. The piston is provided with a movable indicator. Responsive to the tensioned line being provided with tension, the piston moves towards the end of the body, thereby causing the movable indicator to correspondingly move to indicate a tension in the tensioned line of the fire suppression system.

Abstract: An actuation mechanism for use in a fire suppression system includes a housing and a plunger operably coupled to and movable relative to the housing. A tension member is operably coupled to the plunger and applies a tension to the plunger in a first direction. A force generating component is operably coupled to the plunger.

Abstract: An activation system includes a housing and a pulley mounted to the housing. The pulley is rotatable about an axis. An activation member is movable between a first position and a second position relative to the pulley to selectively couple to the pulley. When the activation member and the pulley are coupled, rotation of the pulley about the axis is restricted. A first tension member is operably coupled to the activation member and a first tension of the first tension member maintains the activation member in engagement with the pulley. At least one second tension member is wrapped about at least one of the pulley and the activation member and has a second tension acting on the at least one of the pulley and the activation member.

Abstract: A manual activation system includes a bracket rotatable about a first axis between a first configuration and a second configuration and a pulley movable between an inactive position and an active position. The pulley is mounted to the bracket and is rotatable about a second axis. A tension member is wrapped about the pulley and has a tensile force acting on the pulley. An activation member is configured to cooperate with the bracket to selectively oppose the tensile force.

Abstract: A detection bracket for use in a fire suppression system includes a main body and at least one support plate positioned adjacent to the main body. The at least one support plate has an opening formed therein for receiving an actuation cable wrapped about the main body. The at least one support plate is movable from a first position to a second position relative to the main body in response to a predetermined condition. A tension in the actuation cable receivable within the opening is less when the at least one support plate is in the second position than when the at least one support plate is in the first position.

Abstract: An actuation mechanism of a fire suppression system includes a first input having a first tension, a second input having a second tension, and an output. When the actuation mechanism is in an inactive configuration, the first input and the second input cooperate to maintain a third tension in the output.

Abstract: A fusible mechanical linkage includes a tensioner having an aperture and a spool with guides arranged on an end of the spool opposite the aperture. The guides define a cable seat between one another. A fusible alloy is arranged between the spool and the tensioner, the fusible alloy fixing the spool to the tensioner below a predetermined temperature, the fusible alloy allowing tension carried by an actuation cable received in the cable seat to rotate the spool relative to the tensioner above the predetermined temperature. Fire suppression systems and methods adjusting actuation cables in fire suppression systems are described.

Abstract: A control mechanism includes an actuator having first and second positions, a resilient member arranged to bias the actuator toward the second position, and an input cable. The input cable is arranged along a serpentine path and is connected to the actuator, the input cable arranged to retain the actuator in the first position using tension applied by a plurality of detector cables along the serpentine path of the input cable. Fire detector connector modules, fire suppression systems, and methods of integrating detector cables into control mechanisms are also described.
