4. Mount the ElectroMagnetic Lock with hardware provided (See pages 3).
5. Tighten all screws. Install anti-tamper plugs over socket head mounting screws .
6. Install 1/2” or 3/4” conduit. A conduit outlet box must be provided within 15" of the lock for wire connections.
7. Make all wire connections to a fused power source with the power off .

DISTANCE IN FEET FROM POWER SOURCE TO FARTHEST LOCKING DEVICE
To determine the correct wire gauge to use on a single “circuit” the following information is required :
1. The quantity, voltage and current draw of all lock (s) to be connected to the circuit.
2. The distance in feet from the power supply to the furthest lock on the circuit .
Add together the current draw (amps) of all locks on the same circuit. Using the AWG Chart below, cross reference the
total amps with the distance between the power source and the furthest lock to determine the wire gauge required .
A single “circuit” describes a pair of wires run from the power supply to one or more locks that are wired in parallel . The
distance from the power supply to the furthest lock in the “circuit” must not exceed the distance number shown in the
chart below and is based on your selected wire gauge . If the distance shown in the chart is inadequate for your
application , divide your locks up into 2 or more separate “circuits” and use the chart to check each circuit independently .
Fewer locks on each circuit may allow you to use a smaller gauge wire or will allow you to increase the maximum
distance between the power supply and the furthest lock on the circuit . More than one circuit can be connected on the
same power supply as long as the combined current required from all connected circuits does not exceed the power
supply rating .
NOTE: All wiring must be installed in accordance with all state and local codes .
