Get to Know the DC USA Approved 8500
When the door is closed, the mortise latchbolt is held secure by the DC USA Approved 8500 keeper. A 'deadlatch platform' insert holds the deadlatch in its locked state. Place the deadlatch platform into one of three locations in the strike as appropriate for the type of mortise lockset.
When the electric strike is energized, the keeper begins to rotate and the deadlatch platform falls away, allowing the deadlatch to drop and the latchbolt to become locked.
As the door moves forward, the latchbolt slides first along the keeper and then up the internal ramp.
As the door continues along its arc away from the frame, the latchbolt and deadlatch exit the DC USA Approved 8500, which quickly returns to its locked state.
