Danger Zone Fire Control
Danger Zone Fire Control was a system to prevent guns of one turret from firing when doing so would damage other guns or fixed structures on the ship. It was similar in purpose to the earlier Kilroy Danger Signal, but more assertive in its function, in that it actually locked the firing pistol triggers of the endangering turret. The system was designed so that if power failed, the pistols would lock. The pistol triggers had a switch which could override the locking function.
