TROUBLESHOOTING

Problem:

• Door does not lock

• Status LED is not
illuminated

Door locks, but can be
easily forced open

Delay in door
releasing

No relay output

Delay in door relocking

Possible cause:

No power

Poor contact between
electromagnet and armature
plate

Incorrect voltage setting

• A secondary diode was
installed across the
electromagnet

• No power

• Misalignment

• Check timer

Solutions:

• Check to make sure the wires are securely tightened to the
terminal block.

• Check that the power supply is connected and operating.

• Make sure the lock switch is wired correctly.

• Make sure the electromagnet and armature plate are
properly aligned.

• Make sure the contact surfaces of the electromagnet and
armature plate are clean and free from rust.

• Check the power leads with a meter, and make sure 12VDC
or 24VDC is present.

• The electromagnet is fitted with a metal oxide varistor to
prevent interference, so do not install a secondary diode.

• Check that the power is connected and operating.

• Make sure the lock is aligned properly.

• Make sure the NO/NC/COM are wired properly.

• Make sure timer is adjusted to desired delay time.

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.

HOW IT WORKS

When power is applied to the magnetic lock, it turns on the unit's powerful built-in electromagnet. This electromagnet is
attracted to the steel armature plate which is mounted on a door, holding the door fast against unauthorized entry. When
power to the magnetic lock is turned off, the electromagnet releases the armature plate, allowing the door to open. In
addition, the E-941SA-1K2PD has built-in LEDs to show electromagnet status, plus a status sensor to monitor whether the
door is securely closed, and a built-in adjustable-delay locking timer.

MOUNTING THE E-941SA-1K2PD

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.

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

C. Screw the mounting plate to the door

D. Drill the cable access hole.
E. Mount the electromagnet to the door

F. Connect the power leads (fig. 3):

G. Test the unit.
H. Insert the tamper caps into the

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.

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.

frame (fig. 1) — Use the Allen
wrench to screw the socket-head
mounting screws through the bottom
of the electromagnet into the
mounting bracket.

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.

mounting screw access holes. This
should be the last step, as once the
tamper caps are in place, they will be
difficult to remove.
