ELECTROMAGNETIC LOCK Installation Manual
SECO-LARM U.S.A., Inc.
When power is applied to the electromagnetic lock, it turns on the unit's powerful built-in
electromagnet. This electromagnet is attracted to the steel armature plate which is mounted on
a door, holding the door fast against unauthorized entry. When power to the magnetic lock is
turned off, the electromagnet releases the armature plate, allowing the door to open.

REGULAR MAINTENANCE
• Clean the contact surfaces of the electromagnet or armature plate with a soft cloth and non-abrasive, non-corrosive
cleaner.
• Apply a light coat of a silicon lubricant and wipe away the excess to prevent rust.
• Check that the armature plate is securely attached to the door, yet can pivot slightly around the armature screw.
• Check that the electromagnet is securely attached to the door frame.
TROUBLESHOOTING
Problem:
Door does not lock
Door locks, but can be easily
forced open
Delay in door releasing
Possible cause:
No power
Poor contact between
electromagnet and armature
plate
Insufficient voltage
A secondary diode was
installed across the
electromagnet
Solutions:
• Check to make sure the wires are connected properly.
• Check that the power supply is connected and
operating
• Make sure the lock switch is wired correctly
• Make sure the electromagnet and armature plate are
properly aligned
• Make sure the contact surfaces of the electromagnet
and armature plate are clean and free from rust
• Check the power leads with a meter, and make sure
power is supplied between 12~24VDC.
• The electromagnet is fitted with a metal oxide varistor
to prevent interference, so do not install a secondary
diode

A. Drill holes for the mounting plate and
armature plate (see fig. 1 and 2) by
doing the following:
1. Fold the mounting template along
the dotted line
2. Close the door. Find a mounting
location on the door frame near the
upper free-moving corner of the
door, as close to the corner of the
door frame as possible.
3. Place the template against the door
and frame.
4. Drill two holes in the door frame for
the mounting plate and three holes
in the door as indicated on
template.
5. Only from the sexnut bolt side of the
door, enlarge the 5mm hole to
9mm.
B. Mount the armature plate to the door
using the two steel and one rubber
washer (fig. 2):
NOTE — Actual installation varies
according to door style.
1. Secure the two guidepins into the
two side holes of the armature
plate.
2. Insert the armature screw into the
armature plate, then put the rubber
washer between two steel washers,
and place them over the armature
screw between the armature plate
and the door. This will allow the
armature plate to pivot slightly
around the armature screw in order
to compensate for door
misalignment.
2. Insert the sexnut bolt into the 9mm
hole, then tighten the sexnut bolt and
the armature screw, just enough so the
armature plate can withstand the force
of someone attempting to break down
MOUNTING THE E-941SA-80Q
the door while the electromagnet is
engaged.
3. Do not tighten the armature plate
against the door. The plate must be
able to pivot around the armature
screw.
C. Screw the mounting plate to the door
frame:
1. Remove the L-shaped mounting
plate from the magnet.
2. Insert the provided two 1/8" x 1"
(4 x 25.4 mm) screws into the
L-shaped mounting plate and
screw it to the door frame. The
armature plate and the mounting
plate must be concentric or align
with each other.
D. Drill the power cable access hole.
E. Mount the electromagnet to the door
frame (fig. 1) — Use the Allen wrench
to screw the socket-head mounting
screws through the bottom of the
electromagnet into the mounting
bracket.
F. Connect the power leads (fig. 3):
1. Run two power leads from the
power supply through the power
cable access hole into the
electromagnet.
2. Connect the power leads to the red
and black power input wires of the
unit. Observe correct polarity, red
for positive and black for negative.
G. Test the unit.
