WARNING
!
Warnings indicate potentially hazardous
conditions, which if not avoided or corrected
may cause death or serious injury
NOTICE
Notices indicates a condition that may cause
equipment or properly damage only.
NOTICE
! CAUTION
Cautions indicate potentially hazardous conditions, which if not
avoided or corrected, may cause minor or moderate injury.
Cautions may also warn against unsafe practices.
! CAUTION
The electromagnet lock requires a
face-to-face fitting as shown in figure
otherwise, the holding force will be
greatly decreased (direction of
hydraulic press pull must be collinear).
! CAUTION
Remove any diode installed across the
magnetic lock for spike suppression.
The magnet is fitted with a metal oxide
varistor to prevent back EMF.

Introduction
Features
The E- 41Sx 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.
• MOV surge protection.
• Adjustable mounting bracket.
• Complete mounting hardware for typical
installations.
• "L" bracket and "Z" brackets available for easy
mounting.
• UL2 4 Indoor use, UL1034 Indoor use, UL864
indoor dry use
• Detachable faceplate
• 12/24VDC selectable
•The products shall not impair the intended
operation of an emergency exit or panic
hardware mounted on the door

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, and L-brackets. Please see the diagram on page 3 to
decide if a particular application requires any mounting 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 0-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 0-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.

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 Hex 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.
