AWG WIRE CHART
To determine the correct wire gauge to use on “one circuit” the following information is required:
1. The quantity, voltage, and current draw of all lock(s) to be used.
2. The distance in feet from the power supply to the furthest lock.
Add together the current draw (amps) of all locks on the same circuit. Cross reference the total amps with the distance between the
power source and the furthest lock to determine the wire gauge required.
“One circuit” implies that from the power supply two wires are being run to one or more locks in parallel. The last lock on that pair of
wires from the power supply is not to exceed the maximum distance number as shown on the chart for that gauge of wire, quantity
and type of lock. If the gauge size or maximum distance is inadequate for your application, divide the quantity of locks in that circuit
to create two or more separate circuits and use the chart to figure each new circuit independently even though the same power
supply is being used. This will increase the total number of wires being run but it will allow for a smaller gauge of wire and increase
the maximum distance from the power supply to the furthest lock in that circuit. The chart shows the maximum distance allowable for
a 5% voltage drop from the power supply to the furthest lock on one circuit.
All wiring must be installed in accordance with all state and local codes.

THICK.
STEP 1 EXAMINE DOOR PREPARATION AND HANDING
These instructions are applicable to the two most common
door preparations −Yale Mono Lock and Corbin Russwin
Unilock −as shown in the illustration on the right. If your
door preparation is different, STOP! You need to contact
the factory for instructions specifically for your door
preparation.
STOP! Ensure that the lock handing matches the door
handing and bevel. If it does not match, refer to Step 9
before continuing.

chassis housing.
NOTE: In most cases the chassis mounting posts will fit through the
existing holes in the door.
STEP 4 INSTALL TRIM AND CHASSIS ASSEMBLY
Slide trim and chassis assembly into door from outside.
IMPORTANT: Chassis assembly must be positioned in center of door for proper operation.
STEP 5 INSTALL INNER MOUNTING PLATE
A. Place inner mounting plate onto chassis assembly making sure that
mounting plate slot and latch adapter tab are fully engaged.
B. Secure mounting plate to latch adapter with the two (2) #8-32 x 1/2” flat head
screws supplied.
C. Position flanged nut over chassis assembly and tighten securely with black
hex wrench provided.
D. Optional: Secure mounting plate to door with two (2) #8 x 3/4” Phillips Pan
head self-drilling sheet metal screws or equivalent (not supplied).
