Electric Shear Lock
If the shear lock does not activate when
the door is closed
The magnet assembly is too far away from the armature
assembly.
Adjust the distance between the magnet and armature
assembly by adding more shims under the back portion of
the armature assembly.
Re-adjust the position of the armature assembly or the
magnet assembly.
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.
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.
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.
For any other problems
Test again
Replace the unit
The problem unit can also be substituted for a working unit in
another door frame to see if it works there.
