Notice that PH-450/PH-900 series
of maglocks should be installed
on “inswing” doors and frames
for the sake of security.
Installing the maglock on outswing
doors/frames will pose security
problems.

Important Notes
The electromagnetic lock is failsafe and will require a power supply
unit equipped with battery back up for
fear that power failure may increase
security risks.
Do not install a diode or MOV in
parallel with any magnetic lock. A
diode will cause a delay when
releasing the door.
Apply a light coat of a silicon
Iubricant to prevent the maglock
from rusting. Wipe off the excess.
Do not strand power wires and signal
wires in the same cable or conduit.
Trouble Shooting
Problem
Door does not lock
No power
Reduced holding froce
Poor contact between electromagnet and
armature plate
Low voltage or incorrect voltage setting
Sensor output is not functioning
A secondary diode was installed across
the electromagnet
Misalignment between the armature plate
and its magnet
Possible Cause
Solution
Make sure the wires are securely tightened to the correct terminal block
Check that the power supply unit is connected and operating properly
Make sure the lock switch is wired correctly
Make sure the surface of the armature plate is in good shape
Make sure the rubber washer is inserted behind the armature plate
Make sure the contact surfaces of the electromagnet and armature plate are clean
and free from dust
Check the setting of power input volume
Check the settings of the voltage / current volume on the terminals of the maglock
Remove any diode installed across the magnet for “spike”
suppression. (The magnet is fitted with a metal oxide varistor to prevent back EMF)
Check the faces of armature plate and the maglock are aligned face-to-face
level of height; otherwise, it is necessary to add extra iron boards to make
Stick the templates to the corresponding positions on the door and frame.
Drill the holes for cables and screws according to the templates.
Fix the blind nuts (see illustration below) to secure the maglock.
Wire the maglock.
Fix the armature plate. Plug in the maglock. Close the door and test the
