ELECTROMAGNETIC LOCK Installation Manual
MOUNTING THE E-941SA-300, E-941SA-600 & E-941SA-1200
A. Drill holes for the mounting plate and
armature plate (see fig. 1 and 2) by
doing the following:
1. Fold the mounting template along
the dotted line.
2. Close the door. Find a mounting
location on the door frame near
the upper free-moving corner of
the door, as close to the corner of
the door frame as possible.
3. Place the template against the
door and frame.
4. Drill two holes in the door frame
and three holes in the door as
indicated on the template.
NOTE — A filler plate or an L-bracket
or Z-bracket (optional) may be
required for the electromagnet,
depending on the door frame. See
fig. 1. Z/L brackets are not available
for E-941SA-300.
B. Mount the armature plate to the door
using at least two steel and one
rubber washer (fig. 2):NOTE — Actual
installation varies according to door
style.
1. Put one rubber washer between
two steel washers, and place them
over the armature screw between
the armature plate and the door.
This will allow the armature plate
to pivot slightly around the
armature screw in order to
compensate for door misalignment.
2. Tighten the sexnut bolt enough so
the armature plate can withstand
the force of someone attempting to
break down the door while the
electromagnet is engaged.
3. Do not tighten the armature plate
against the door. The plate must
be able to pivot around the
armature screw.

4. Make sure the anti-spin guides are
in the two guidepin holes.
C. Screw the mounting plate to the door
frame or optional bracket:
1. Screw the two short self-tapping
screws in the slotted holes of the
mounting plate and adjust the
position of the mounting plate so
that it and the armature plate form
a 90-degree angle.
2. Once the position is correct, use
the long self-tapping screws to
permanently mount the bracket.
3. Remove the two short screws.
D. Drill the cable access hole.
E. Mount the electromagnet to the door
frame (fig. 1) — Use the Allen wrench
to screw the socket-head mounting
screws through the bottom of the
electromagnet into the mounting
bracket. (Brass sleeves will be needed
for the E-941SA-600.)
F . Connect the power leads (fig. 3):
1. Open the electromagnet.
2. Run two power leads from the
power supply through the cable
access hole into the
electromagnet.
3. Connect the power leads to the
terminal block.
4. Close the electromagnet.
Note: E-941SA-300 is for 12VDC
operation only. Connect the red wire to
+12VDC, and the black wire to ground.
G. Test the unit.
H. Insert the tamper caps into the
mounting screw access holes. This
should be the last step, as once the
tamper caps are in place, they will be
difficult to remove.
