Installation Manual

Problem Possible Cause Solution
Door does not lock
No power
Poor contact between electromagnet and
armature plate
Low voltage or incorrect voltage setting
A secondary diode was installed across
the electromagnet
Misalignment between the reed switch
and its magnet
Check to make sure the wires are securely tightened to the correct terminal block
Check that the power supply is connected and operating properly
Make sure the lock switch is wired correctly
Make sure the lock switch is wired correctly.
Make sure the contact surfaces of the electromagnet and armature plate are clean
and free from dust
Check the installation of armature with supplied template.
Make sure the electromagnet and armature plate are properly aligned
Ensure the electromagnetic lock is set for the correct voltage.
Check for proper voltage at the electromagnetic locks input. If low, determine if the
correct wire gauge is being used to prevent excessive voltage drop.
Remove any diode installed across the magnet for "spike"
suppression. (The magnet is fitted with a metal oxide varistor to prevent back EMF)
Reduced holding force
Sensor output is not functioning

Distance in feet from power source to farthest locking device
Important Notes
Trouble Shooting
Do not run power wires and signal
wire in the same cable or conduit.
The contact surface of the
electromagnetic lock and the armature
plate has to be completely attached;
otherwise, the reed, which located in
side the electromagnetic lock, will not
be detected. It will result an incorrect
output message for the bond sensor.

Be aware that it is better to install
the electromagnet lock inside the
house and hide the cable inside the
door frame in order to against the
unlawful entry.
In-swinging
The electromagnetic locks are fail-
safe and will require a power supply
equipped with battery back up when
power outages may interfere with
desired security.
Do not install a diode in parallel
with any magnetic lock. A diode
will cause a delay when releasing
the door and residual magnet to occur.

Damage to the mating surfaces may
reduce the efficiency of the lock and
cause rust.
Apply a light coat of a silicon
lubricant to prevent rust. Wipe
away the excess.

During the installation procedure, it
is important to make sure that the
working direction of the armature
plate has to be facing toward the
contact surface of the electromagnetic
lock intend to have the maximum
holding force.
