If the Electromagnet has low or no holding force, check the resistance of the coils by
performing the following steps:
1. Remove the faceplate from the lock.
2. Disconnect the wire harness from the circuit board.
3. Using a meter, measure the resistance across:
Red / Green wires, and the Black / White wires.
4. Each coil should test at 48Ω ±10%.
5. If one or both of coils shows an open, short, or incorrect
resistance, replace the electromagnet.

Introduction:
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.
Features:
• 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:
Green Door is closed and locked
Red Door not closed and/or locked

Installation Applications:
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.

Installation Notes:
ELECTROMAGNETIC LOCK
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.
Installation:
1.
Fold the mounting template along the dotted line to
form a 90-degree angle.
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.

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.
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.

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.
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.

. 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.
