SECO-LARM ELECTROMAGNETIC LOCK
Table of Contents:
Introduction:
Features:
The E-941SA series of electromagnetic locks is the ideal way to secure a door against unauthorized entry.
When power is applied to the electromagnetic lock, it creates an extremely strong magnetic field. The
electromagnet is strongly attracted to the steel armature plate which is mounted on the secured door. Once the
electromagnet is deactivated, the secured door will function normally without any residual magnetism.
Anodized aluminum.
No residual magnetism.
MOV surge protection.
Adjustable mounting bracket.
Complete mounting hardware for typical installations.
“L” bracket and “Z” brackets available for easy mounting. *
12/24VDC selectable.*
Detachable faceplate.*
E-941SA-1K2PQ and E-941SA-600PQ also feature:
Built-in dual-colored status LED and bond sensor to show
locking status:
E-941SA-300 features:
Weatherproof for outdoor use.
Pre-installed 36” (91cm) hookup wire included.

NOTE: When mounting the electromagnet, it may be necessary to use a “Z”-bracket, 1 or 2 “L”-brackets,
and/or plate spacers, depending on the location and the type of door and frame. Use the diagram below to
help decide whether or not an optional bracket will be necessary for installation.
See page 7 for a complete list of SECO-LARM accessories.

1. Read this installation manual thoroughly. A clear understanding of the product and this
manual will make installation much easier.
2. The electromagnetic lock is designed for indoor use ONLY.
3. The most suitable mounting location for the electromagnetic lock may require the use of
additional SECO-LARM accessories such as Z-brackets, L-brackets, and/or spacer plates.
Please see the diagram on page 3 to decide if a particular application requires any mounting
accessories. See page 7 for a complete list of SECO-LARM accessories.
4. Do not run power wires and signal wires in the same conduit as this may cause interference.
5. Do not install a diode in parallel with the electromagnetic lock as this may cause a delay
when releasing the door as well as cause residual magnetism.
6. The best location to install the electromagnetic lock is on the inside of the door that is being
secured with the wiring concealed in the frame to prevent tampering with the unit.
1. Fold the mounting template along the dotted line to
form a 90-degree angle.
4. Drill two holes in the frame and
three holes in the door as shown
on the template.
5. Use a hammer to lightly tap the
guide pins into the guide pin
holes on the armature plate.
2. Close the door. Find a mounting location on the door
frame near the upper free-moving corner of the door,
or as close as possible to the upper corner of the
door frame opposite the hinges.
3. Place the template against
the door and frame. Mark
where the holes are to be
drilled.

7. Put a rubber washer between the two metal washers,
and place them over the armature screw between
the armature plate and the door. This allows the
plate to pivot around the screw to compensate for
door misalignment.
9. Screw the two short self-tapping screws through the mounting plate’s slotted holes, but do not over-tighten them.
Keeping them loose will allow for adjustment of the plate left or right so that the mounting plate and the armature
plate form a 90-degree angle. See the diagram below.
8. Tighten the armature screw enough so that the
armature plate can withstand a break-in attempt, but
loose enough so that the armature plate can pivot
slightly. Make sure the anti-spin guide pins are in the
two guide pin holes.

6. Depending on the type of door being protected, drill holes according to the diagrams below:
Hollow Metal Door
Solid Core Door
Reinforced Door
1/4” (6.8mm) for M8x1.25 thread
Drill a 5/16” (8mm) dia. hole through the
armature-plate side of the door for the
armature screw. Then drill a 5/8” (16mm)
dia. hole for sexnut screw on the
opposite side of the door.
Drill an 5/16” (8mm) dia. hole on the
door for the armature screw, and drill a
1/2” (12.7mm) dia. and 1” (25mm) deep
hole for the sexnut screw.
Drill a 1/4” (6.8mm)
dia. and 1” (25mm)
deep hole, tap for
M8x1.25 thread.
Tip: Use a thread-locking compound
on the armature screw to ensure
a long-lasting installation.

14. Cut the wires so they are long enough to connect
with the terminal block. Set the voltage using the
selection jumpers based on your input voltage.
10. Once the position of the mounting plate is correct,
use the four long self-tapping screws to permanently
mount the mounting plate.
11. Drill the cable access hole. Run the power leads
through the cable access hole in the mounting plate
and through the hole in the door frame.
12. Remove the cover from the front of the
electromagnet. Run the power leads through the
large cable access hole .
13. Push the electromagnet against the mounting plate
so the electromagnet ends are flush with the ends of
the mounting plate. Use the Allen wrench to screw
the hex-head mounting screws through the bottom
of the electromagnet into the mounting bracket.

NOTE: This should be the very last step, as once the
tamper caps are in place they are very difficult to remove.
NOTE: Failure to correctly set the input voltage may cause
damage to the lock.
NOTE: Connect switching devices like push-to-exit
switches between the power source and the positive
terminal on the lock. Connecting switching devices to the
negative terminal may cause a delay in unlocking.

15. Connect the power wires according to the wiring
diagram on page 7. Test the unit. Then replace the
front cover and install the hex-head tamper caps.
