Installation Applications
 When mounting the electromagnet, it may be necessary to use a "Z" and "L" bracket, an
"L" bracket, a "U" bracket, 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.
Installation Notes
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.
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.
7. The minimum permissible wire size to be used shall not be less than 22AWG.

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. Use a hammer to lightly
tap the two guide pins into
the guide pin holes on the
armature plate.

the door and frame. Mark
where the holes are to be
drilled.

template and in step #6
below. The smaller holes on
the door should not go all
the way through.

Installation (Continued)
7. Put a rubber washer between the two
metal washers and place them over the
armature screw between the armature
plate and the armature plate holder. This
allows the plate to pivot around the screw
to compensate for door misalignment.
The rubber washer
is
sandwiched
between the two metal washers
and all three are placed between
the armature plate and the
armature plate holder.
Metal washers
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.

TIP
Use a thread-
locking compound
on the armature
screw to ensure a
long-lasting
installation.

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 so that the long
edge of the mounting plate and the armature plate are parallel. See the diagram below.

11. Drill the cable access hole. Run the wiring
through the cable access hole in the
mounting plate and through the hole in the
door frame.

Installation (Continued)
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.
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.
NOTES
Failure to
correctly set the input voltage may
cause damage to the lock.
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.
Position 2 jumpers on
all four pins for 12VDC
operation (default)

15. Connect the power and other wires
according to the wiring diagram on page 7.
Test the unit. Then replace the front cover
and install the hex-head tamper caps (x2).
NOTE: This should be the very last step after all
steps are confirmed, since once the
tamper caps are in place, they are very
difficult to remove.

Troubleshooting
Doors lock, but can easily
be forced open
 Make sure the electromagnet and armature plates are properly
aligned.
 Make sure the contact surfaces of the electromagnet and armature
plates are clean and free from rust.
 Check the power leads with a meter, and make sure 12VDC or
24VDC is present.
 Make sure the rubber washer is installed and free from damage.
Delay in door releasing
 The electromagnet is fitted with a metal oxide varistor to prevent
interference, so do not install a second diode.
 Ensure that the control device is connected between the power
source and the positive terminal of the lock
