Description______________
NS400M and NS400MC Series
Deadlatches are pin tumbler, motoroperated locks for swinging doors.
Specify builders hardware cylinders and
keying as follows:
NS402M/MC Keyed one side
NS406M/MC Keyed both sides
Note: See optional features for factory or
customer-supplied key cylinders. For Models
NS400M and NS400MC, no cylinders are
supplied.
Applications_____________
Specify for minimum/medium security
swinging cell, corridor or administration
areas of institutions, with 2" wide
hollow metal jamb construction.
Operations______________
A remote switch is used to control the
lock electrically, or may be operated
mechanically by a builders hardware key
cylinder. These locks offer the
convenience of remote, electric
unlocking or locking and automatic
deadlocking when the door is closed.
Motor-Actuated Models
Unlock when the motor is energized
(1): by a momentary-contact switch.
Latchbolt is held mechanically retracted
until the door is opened. It then extends
automatically (mechanical latchback).
Two-Position Motor Actuated Models
Lock or unlock when the motor is
energized (1): by either a two or three-
position maintained-contact switch, or
by a three-position, momentary-contact
switch. When unlocked by control
switch, latchbolt remains retracted
by motor position until control switch is
set to lock. Latchbolt is held
mechanically retracted until the door is
opened. It will then extend
automatically, if the control switch is set
to the lock position (mechanical
latchback).
Lock or unlock when the motor is
energized (2): by either a two or three-
position maintained-contact switch, or a
three-position momentary-contact
switch. Latchbolt then remains retracted
until selected to lock. Opening and
closing the door has no effect on the
lock (no latchback).
Unlock when the motor is energized
(3): by a momentary contact switch. A
relock switch energizes the motor to
relock once the door is open. On
closure, the latchbolt deadlocks
automatically (no latchback with relock).
