The E-941Sx series of electromagnetic locks is the ideal way to secure a door against unauthorized entry. When power is
applied to the electromagnetic lock, it creates an extremely strong magnetic field. The electromagnet is strongly attracted
to the steel armature plate which is mounted on the secured door. Once the electromagnet is deactivated, the secured
door will function normally without any residual magnetism.

3. The most suitable mounting location for the electromagnetic lock may require the use of additional
SECO-LARM accessories such as Z-brackets, and L-brackets. Please see the diagram on page 3 to

decide if a particular application requires any mounting accessories.

6. The best location to install the electromagnetic lock is on the inside of the door that is being secured
with the wiring concealed in the frame to prevent tampering with the unit.

Installation:

1.

Fold the mounting template along the dotted line to
form a 90-degree angle.

2.

Close the door. Find a mounting location on the door
frame near the upper free-moving corner of the
door, or as close as possible to the upper corner of
the door frame opposite the hinges.

3.

Place the template against
