in which the product will be installed must be performed.
3. The door frame must be inspected and deemed structurally
sound prior to installation of the electromagnetic lock. The
structural integrity of the mounting surfaces must be strong
enough to meet or exceed the holding force of the product.
4. The product must be protected from potential damage due
to intruders or tampering.
5. The product should be installed in a location that will not
hinder or create a potential safety hazard to authorized
personnel accessing the protected area.
6. Because electromagnetic locks are used in a variety of
applications and different door frame configurations, an
experienced installer with knowledge of this product must
make a determination of the optimal mounting method for
this specific application.
7. The components, hardware, installation instructions and
mounting template included with this product are intended

1.
on the installation template included with the product.
NOTE: During installation of the armature plate to the door it is
essential that the armature plate remains movable. The armature
plate must be allowed to pivot on the center-mounting bolt to
allow proper alignment with the magnet surface. If the plate is
not aligned with the magnet surface, the lock may lose holding
force or not lock at all.
The head of the armature mounting bolt ships with a rubber
washer affixed to it. this washer should project slightly beyond
the surface of the armature plate. This is to allow the washer
to expand when power is removed and break the air vacuum
between the plate and the magnet surface. If this washer is
removed or trimmed the lock will appear to have some holding
force even when power is removed.
