Non-Holdback (Optional) – Latchbolt retracts only through the full cycle operation or is held back through half cycle operation.
Knob Release (Optional) – Opposite side of cylinder provides retraction of latchbolt at any time.
Local Electric Key (Optional) – Electrically unlocks deadlatch by key at cylinder.
Cylinder Extension (Optional) – Extends mogul cylinder through frame. Available in 3”, 5” or custom lengths.
Function
The 120MC Deadlatch is a motor-operated lock. When the door 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 first switch position rotates the motor half way and unlocks the lock. The lock will remain unlocked until the second 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.
