INSTALLATION INSTRUCTIONS
ML-1500 SERIES ELECTROMAGNETIC LOCK
The ML-1500 Series ElectroMagnetic Lock is mounted to the
underside of the header, on the stop side of the door.
The armature is mounted to the door. A hardware kit is provided to
compensate for misalignment and wear of the door, by allowing the
armature to pivot on it’s center point.

2. Fold template as indicated by dotted line. For single doors, locate
template against the door and header on the lock jamb side of the
frame.
3. Mark and drill holes as indicated by template . For armature plate hole
preparation, see Figure 2A, 2B, 2C.
3A. Add both spring pins to armature plate. See page 4.
4. Mount armature to door. To determine proper hardware (provided), see
Figure 2A, 2B, 2C.

door side of the stop, with #10 Flt Hd. Screws provided.
6. Holding the magnet housing at each end, engage the entire
length of the interlock detail, by pushing towards the door.
(If necessary, tap with a soft hammer to ensure proper alignment
and engagement).
Caution: The lock body must be held in place until
secured with mounting screws. Screws provided inside the
housing at each end. Tighten the screws and check alignment.
7.
Remove front plate to access electronics. See page 2 for wiring.
8. Test operation. When all is operating properly, tighten all
screws. Install anti-tamper plugs over socket head screw
using a soft hammer to avoid damage to the housing.
Electromagnet and armature should be handled carefully.
Any damage to the surface such as paint, burrs, dirt and rust
may hinder bonding of surface and reduce holdi
ng power.

SHOULD THE SURFACE PLATING BE DAMAGED:
Do not touch the lock face with your hands.
Using a soft, clean, dry cloth or abrasive cloth (i.e., Scotch-Brite),
clean lock face. Do not use sand paper.
A rust inhibitor such as M1, manufactured by Starret, or LPS3,
manufactured by LPS Laboratories (available at most hardware stores)
can then be applied. Apply a coat of inhibitor to armature face al
so.

IMPORTANT NOTES
INDOOR USE ONLY
1. Use jacketed cable for all wire runs. Refer to the AWG wire

gauge minimum).
2. All wires must be colored coded.
3. Use properly fused power source only. See Electrical
Specifications.
4. Make all ElectroMagnetic Lock terminal connections according to
Figure 3
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 distanc
e between the
power source and the furthest lock to determine the wire gauge required. All wiring must be installed in accordance with all state and
local codes.
