Fire suppression systems and methods

A fire suppression system, comprising:

• a sensor assembly having a temperature-sensitive release mechanism;
• an activation assembly configured to discharge fire suppressing fluid from a fire suppressing fluid source;
• and
• a flow control assembly configured to maintain a constant discharge flow of the fire suppressing fluid;
• wherein the activation assembly includes:
• a connector configured to be coupled to a fire suppressing fluid source,
• a barrier configured to separate fire suppressing fluid of the fire suppressing fluid source from the flow control assembly,
• a puncturing device configured to move between a proximal position in which the puncturing device is spaced from the barrier, and a distal position in which the puncturing device punctures and extends through the barrier,
• a first spring configured to urge the puncturing device toward the distal position,
• a locking member configured to move between a locking position in which the puncturing device is secured in the proximal position against the urging of the first spring, and an unlocking position in which the puncturing device is released from the proximal position allowing the first spring to urge the puncturing device toward the distal position,
• an interlock pin configured to move between a retracted position in which the locking member is secured in the locking position, and an extended position in which the locking member is allowed to move to the unlocking position,
• a second spring configured to urge the interlock pin toward the extended position,
• wherein the temperature-sensitive release mechanism is configured to secure the interlock pin in the retracted position against the urging of the second spring, and to release the interlock pin and allow the second spring to urge the interlock pin toward the extended position when the temperature-sensitive release mechanism is exposed to a predetermined first temperature that corresponds to presence of a fire.
