NS400E Series Deadlatches are pin
tumbler, solenoid-operated locks for
swinging doors. Specify builders
hardware cylinders and keying as
NS402E & NS402EFS
Keyed one side
NS406E & NS406EFS
Keyed both sides
Note: See optional features for factory or
customer-supplied key cylinders. For models
NS400E and NS400EFS, no cylinders are
A remote switch is used to control the
lock electrically, or it may be operated
mechanically by builders hardware
cylinder. These locks offer the
convenience of remote, electric
unlocking or locking and automatic
deadlocking when the door is closed.
Fail-Safe Models
Unlock when solenoid is de-energized
(1): by switch or power failure, and the
latch remains retracted while the door is
open. Upon closure, with power
restored, the latchbolt extends and
Non-Fail-Safe Models
Unlock when solenoid is energized
(1): by a momentary-contact switch.
Latchbolt remains retracted mechanically
until the door is opened. Upon closure,
the latchbolt extends automatically
(mechanical latchback).
Unlock when solenoid is energized
(2): by a momentary-contact switch.
Latchbolt is electrically held retracted
only as long as control switch is tripped
(no mechanical latchback). The door
must be opened while control switch is
in the unlocked position. Upon closure,
the latchbolt deadlocks automatically.
Continuous-duty feature is standard to
hold bolt retracted for extended periods
(no latchback, continuous-duty power
Unlock when solenoid is energized
(3): by a momentary-contact switch.
Latchbolt is held electrically retracted
until door is opened, then it extends
automatically (electric holdback).
Specify for minimum/medium security
swinging cell, corridor or administration
areas of institutions with 2″ wide hollow
metal jamb construction.
