The NightWatch

mechanism consists of a simple mechanical deadbolt within the

thumb turn mechanism. The inside view of the thumb turn assembly here displays

the interlocking features. The spindle of the thumb turn has two depressions cast into

it and those depressions match two projections from the mounting plate when the

spindle is turned 90° to extend the bolt.

The movable button on the bottom of the mounting

plate can be pressed upward, and that allows the

thumb piece to be pulled outward and engage the

interlocking features. Shown (left) is a side view of the

spindle and mounting plate. Note the spindle deadlock

and the groove in the spindle.

The button at the bottom of the mounting plate raises the spindle deadlock out of the groove

in the spindle and allows it to be pulled outward. When it is pulled outward the two parts

interlock and prevent the thumb turn from being turned at all unless it is ﬁrst pushed inward.

Because the cylinder tailpiece also enters the spindle, when the spindle is immobilized, the

tailpiece is too, and the cylinder cannot be used to operate the lock.

In the combination deadbolt, the dial mechanism is connected to a cam that turns the

tailpiece, and this also is rendered inoperable.

The NightWatch

function is only available in single cylinder deadbolts and combination deadbolts.

First, use the Allen wrench

provided in the hardware

package to remove thumb turn,

washer and separate rose from

rose plate. (see below)

To separate the rose plate

from the base, locate the

notch on the back side of

the base (the cover edge

extends above the base in

the notch area) and use

a screwdriver to apply

pressure to the edge of the rose cover separating it

from the base.

Torque Blade

To install plate, align torque

blade with turn piece

assembly, insert screws

through plate, through latch

and into the threaded holes in

the exterior housing. Tighten

screws. Snap rose onto rose plate. Attach thumb turn (see

below) and tighten set screw with Allen wrench.

When you reattach the thumb

turn, be sure that the recess in

the spindle is pointing down.

The set screw projects into this

recess when tightened.
