HOW THEY WORK
When power is applied to the magnetic 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.

ELECTROMAGNETIC LOCK Installation Manual
TROUBLESHOOTING
Problem:
Possible cause: Solutions:
Door does not lock
No power
• Check to make sure the wires are
securely tightened to the terminal block
• Check that the power supply is connected
and operating
• Make sure the lock switch is wired
correctly
Door locks, but can be
easily forced open
Poor contact between
electromagnet and
armature plate
• 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
Incorrect voltage
setting
• Check the power leads with a meter, and
make sure 12VDC or 24VDC is present
Delay in door releasing
A secondary diode was • The electromagnet is fitted with a metal
installed across the
electromagnet
oxide varistor to prevent interference, so
do not install a secondary diode
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 to prevent rust. Wipe away the excess.
• 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.
UL CERTIFICATION
