Description

 Description______________
Series 120MC Deadlatches are pin
tumbler, motor-operated locks utilizing a
two-position motor cam.
Specify keying as follows:
121 Keyed case side
122 Keyed cover side
126 Keyed both sides
  Operations______________
Standard (1): Unlocks when the motor is
energized by either a two or three
position, maintained contact switch, or a
three position momentary contact switch.
Once unlocked, the latchbolt remains
retracted until it is selected to lock.
Opening and closing the door has no
effect on the lock when selected to
unlock. The latchbolt extends only when
the door is opened and the motor is
selected to lock. If the door is closed, it
must be opened to extend the latchbolt.
Two additional variations on this feature
are offered:
Without latchback (1a): Once unlocked,
the latchbolt is held retracted only as long
as the motor remains in the unlocked
position. A maintained-contact switch may
be used to keep the latchbolt retracted for
an extended period of time.
Relock (1b) 09: Once unlocked, the
latchbolt is held retracted until the door is
opened. It then extends automatically.
This operation requires an additional
control wire, and may be cancelled by
adding an additional control switch. A
momentary-contact switch is used for
unlocking, and the auxiliary switch is used
for relocking. When the door is opened,
the auxiliary switch repositions the motor
to a locked position so that the lock will
deadlatch on closure.
Knob release(2): 120MC Deadlatches
may be specified with knob release on
one side, where the knob is always active.
Knob may be mounted on the case side,
or the cover side.
Key holdback (3): When unlocked by key,
the deadlatch remains retracted until
relocked by turning the key in the opposite
direction. Available one side only.
Note: Key cylinders for locks with key holdback
feature must be installed at the factory.
 Applications_____________
Series 120MC Deadlatches are suitable for
use in medium or maximum security
situations to lock cell, corridor or entrance
doors. Especially appropriate for areas
requiring the latchbolt to remain retracted
until it is selected to lock again.
Like all Series 120 locks, the jambmounted
120MC Deadlatch is designed
for use as part of an electrical system with
remote operation and monitoring.
