ELECTRIC SHEAR LOCK Installation Manual
TROUBLE SHOOTING
1. If the shear lock does not activate when the door is closed, it may be because the
magnet assembly is too far away from the armature assembly. You can either:
a. Adjust the distance between the magnet and armature assembly by adding more
shims under the back portion of the armature assembly.
b. Re-adjust the position of the armature assembly or the magnet assembly.
2. Poor attraction between the magnet assembly and the armature assembly — Check
the power supply, and make sure it is according to specifications. If the power
supply is adequate, replace the unit.
3. If the magnet assembly pulls the armature assembly, but the door can still be
opened, check to make sure the locking bolts are in the armature assembly's keeper
hole when the unit is activated.
4. If the door can be kicked in or pushed in with your shoulder, check to make sure the
magnet assembly and armature assembly surfaces are clean and free from dirt. Even
a little dirt could reduce the attraction between the two surfaces.
5. For any other problems, replace the unit, and test again. The problem unit can also
be substituted for a working unit in another door frame to see if it works there.

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.
