Description______________
Series 120E Deadlatches are pin
tumbler, solenoid-operated locks for
swinging doors. Specify keying as
follows:
121 Keyed case side
122 Keyed cover side
126 Keyed both sides
Applications_____________
Series 120E Deadlatches are suited for
medium or maximum security
application including cell doors, sallyport
or egress doors, corridor or entrance
doors. Sensitive administration areas of
an institution may also warrant 120
Series locks. These jamb-mounted locks
are designed to be part of an electrical
system with remote operation and
monitoring to provide supervisory
personnel with optimum protection and
flexibility.
Operation_______________
Standard (1): Series 120E locks unlock
when the solenoid is energized by a
momentary-contact switch. Once
unlocked, the latchbolt is held
mechanically retracted until the door is
opened. It then extends automatically.
Without latchback (1a) 04 one switch;
05 two switches: Once unlocked, the
latchbolt is held retracted as long as the
solenoid is energized. A maintained
contact switch may be used to keep the
latchbolt retracted for an extended
period of time.
Knob release(2): 120E 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. For locks keyed both sides,
available cover side only.
Note: Key cylinders for locks with key holdback
feature must be installed at the factory. This
function is not UL Listed for Fire Doors.

installation eliminates the need for
cover removal.
Standard lock – Mounts behind
frame and does not require a
faceplate.
1" throw latchbolt – Offers greater
security. Each bolt is hardened to
resist sawing. When latchbolt is
engaged in strike, bevel is concealed
to prevent picking.

Optional Features________
Optional solenoid voltage –

Faceplate – US32D finish.
Indication/auxiliary switches –
An indication switch monitors the
deadlock lever indicating a
deadlocked latchbolt. The auxiliary
switch monitors the UROOHUEROW for
extended or retracted position.
Local electric key (LEK) – A unique
function which uses two types of keys
for applications where inmates carry
their own keys, but supervision is
necessary. One key turns in one
direction only and operates the lock
electrically. The supervisory key turns
in both directions to operate the lock
electrically and mechanically. The
electric operation may be cancelled
from a central console or control
point at any time via a three-position
switch.
®
The Maxi-Mogul
uniquely suited for this high
frequency operation, shown by cycle
test of 1,000,000 operations.
LEK not available on any 120E-3
Series Locks.
Key Cylinder Extension – When the
lock is keyed on the stop side of the
jamb, an extension eliminates the
need for a special, recessed frame
pocket. Specify E-3 for 3", E-4 for 4"
or E-5 for 5".
The chart at right shows applicability
of above options to all 120E Models.
