What is the maximum pull force allowed for manual controls?

Explanation:
Manual release devices for NFPA 2001 are designed to be operable by a person in an emergency, yet resistant to accidental activation. The standard sets a maximum pull force of 40 pounds (178 newtons), which strikes a balance: it’s enough for reliable manual activation under stress, but not so light that everyday contact could trigger a discharge. If the force were higher, operation could be slow or difficult in an urgent situation; if there were no limit, accidental releases could be more likely. So the authorized maximum is 40 pounds.
