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
