51MC Motor-Operated Deadlatch
The 51MC is a motor operated lever tumbler lock designed for a variety of swing door applications such as inmate rooms, housing and dayroom perimeter doors, corridors and exterior doors.
Operation Details
The 51MC deadlatch is a motor operated lock. When the door is in a locked closed condition. the latchbolt is deadlocked preventing the latchbolt from being retracted. Once the motor is energized, the deadlatch is lifted and the latchbolt is allowed to retract, unlocking the lock. The motor is equipped with a motor switch that allows for a half cycle operation. The half cycle (MC) operation uses a two position switch. The 1st switch position rotates the motor half way and unlocks the lock.
The lock will remain unlocked until the 2nd switch position rotates the lock and returns to a locked condition with the latch projected, once the door is closed. Half cycle typically uses “Non-Holdback” as described below. The deadlock indicator switch provides monitoring of the deadlocked condition as well as the full projection of the latchbolt.The half cycle lock is usually specified as “Non-Holdback”, which holds the bolt back only during the half cycle position.
