Description______________
Series 51P Deadlatches are lever-
tumbler, pneumatically-operated locks
for swinging doors. Specify keying as
follows:
52P Five-tumbler lock,
keyed cover side.
52P-6 Six-tumbler lock,

56P Five-tumbler lock,

Applications_____________
51P Deadlatches are designed for jamb-
mounted installation, and provide
maximum security for heavily-used cell,
corridor, or entrance doors. They
provide the convenience of slam-
locking with remote unlocking.
Operation_______________
Standard (1): When connected to a
momentary-contact switch, the latchbolt
retracts when the pneumatic solenoid is
energized. Once retracted, the latchbolt
is held mechanically retracted until the
door is opened. The latchbolt extends
when the door is open.
Standard (1a): When connected to a
maintained-contact switch, the latchbolt
retracts when the pneumatic solenoid is
energized. Once retracted, it is held
electrically retracted for an extended
period of time. The latchbolt extends
only when the door is open and the
solenoid is de-energized.
No-notch (2): Latchbolt
extends when the switch
is selected to lock.
(No-notch feature, see
description on page B10.)
