Basic Installation Concept & Accessories
LZ bracket for Inswing doors
-
Find a mounting location on the door frame for the L bracket. Make sure that the door is still closeable.
-
Use the fixing bolt to tighten the electromagnetic lock on L bracket
-
Assemble the Z bracket, and make sure that the position of the Z bracket is adjustable.
-
Insert the guide pins into the armature plate.
-
Fasten the armature plate to the Z bracket (Must add rubber washer)
-
Close the door and connect the power.
-
After the maglock attracts the armature plate, adjust the Z bracket to fit the door.
Standard Installation
-
Fold the mounting template 90°
-
Place the template to the proper position of the door and frame. Mark the hole positions of the template on the door and frame.
-
Drill the holes according to the marks.
-
Please install the armature plate as illustrated here. (Dimensions of the holes depend on the door types illustrated below.)
-
The rubber washer makes the surface of the armature plate adjustable in order to completely fit the surface of magnetic lock.
-
Fasten the mounting plate with the mounting screws. The position of the mounting plate should be adjustable.
-
Fix the mounting plate on the door with mounting screws
-
Use the Allen wrench and fixing bolts to tighten the electromagnetic lock to mounting plate
-
Connect the power and test the unit.
Connecting Diagram
Trouble Shooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door does not lock | No power | Make sure the wires are connected properly |
Check that the power supply is connected and works properly Make sure the lock
switch is wired correctly (N.C.)
Low holding force|
Poor contact between electromagnet and armature plate
| Make sure if the armature plate is deformed
Make sure if the rubber washer was used between magnet lock and armature plate
Make sure the contact surfaces of the electromagnet and armature plate are
clean and free from dust
Low voltage or incorrect voltage setting| Ensure the electromagnet 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.
Sensor output is not functioning
| A secondary diode was installed across the electromagnetic lock| Remove any
diode installed across the magnet for “spike” suppression. (The magnet is
fitted with a metal oxide varistor to prevent back EMF)
Misalignment between the armature plate and electromagnetic lock| Make sure
the armature plate and electromagnetic lock are aligned correctly
