Lock Monitoring
Features
Remote indication features that provide
indication as to the lock status.
Magnetic Bond
Sensor (MBS)
Detects proper bond between magnet and
armature. It can be monitored remotely and
locally with an LED.
Door Status
Monitor (DSM)
Monitors the position of the door. An SPDT
reed switch mounted within the lock cavity
eliminates the need for extra sensors to be
installed on the door for notification of
security or access control systems.
Relock Time Delay
(RTD)
Relock time can be changed. Range is 0 -
110 seconds.

Inspection and Maintenance
This product must be inspected and maintained on a quarterly
basis. Contacting surfaces of the electromagnetic lock and
armature plate must be kept free of contaminating materials.
Surfaces must be cleaned periodically with a non-abrasive
cleaner.
All mounting fasteners must be inspected on a quarterly
basis.
When properly installed, the ends of the armature plate allow
a slight movement but the plate will feel secure when grasped
at the bolt. There should be no movement to the mounting
bracket or housing of the electromagnetic lock.
For added safety, thread locking compound has been provided
for the armature plate bolt and the four captive
electromagnetic lock mounting screws.
Warnings and Cautions
WARNING
Warnings indicate potentially hazardous conditions, which if
not avoided or corrected, may cause death or serious injury.
CAUTION
Cautions indicate potentially hazardous conditions, which if
not avoided or corrected, may cause minor or moderate
injury. Cautions may also warn against unsafe practices.
LNotes indicate a condition that may cause
equipment or property damage only.
Pre-Installation Considerations
CAUTION
• Use ONLY the hardware provided for mounting this
product.
• Non-standard Door thickness may require different
barrel nut hardware - see specific instructions for
required hardware.
• Follow the installation procedure as described in this
manual.
• Check door thickness. If the door is not 1 ⁄ " thick, a
different barrel nut will be required. Contact Product
Support at 1-877-671-7011.
• Check door header. A minimum 2 ⁄ " thick, flat surface is
needed to securely mount all screws for the magnet. If
you do not have the required surface, you will need filler
plates and/or angle brackets to properly mount the
magnet. Contact Product Support at 1-877-671-7011.
Door: 1 ⁄ " Thick
Header: At least 2

Lock Installation
1 Prepare door and frame (for new installs).
1a Place included template against closed door and header
with allowance for Allen key clearance from the edge (1 ⁄ ”).
1b Drill the middle hole in the door and two (2) holes in the
header as indicated. Center-mark the two holes to mount
armature holder.
LDifferent hole sizes required for different materials,
as referenced on the template.

2 Mount armature plate.
2a Position screw with rubber head through the armature plate.
LApply thread-locking compound to exposed
threads.
2b Secure armature plate to door and armature holder by
threading into barrel nut. See Figure 1: Armature
Mounting.
LArmature 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.
LThe head of the armature mounting bolt ships with
a rubber washer axed to it. This washer should
project beyond the surface of the armature plate to
allow the washer to expand when power is
removed and break the air vacuum between the
plate and magnet surface. If this washer is
removed or trimmed, the lock will appear to have
some holding force even when power is removed

3 Mount lock.
3a Remove blocking screws from front of lock.
3b Remove lock from mounting bracket by loosening captive screws and sliding off keyholes.
New lock installation:
3c Attach bracket to header with the two (2) panhead
machine screws or the self-drilling screws provided through
the slots.
LDo not over-tighten these screws as the bracket
may need adjustment.
LMounting Bracket should be installed such that the
Panhead screwheads fit within the recessed area
of the slot.
3d Slide lock onto mounting bracket keyholes. Engage one
captive screw at each end through bottom to fix lock
position on bracket.
3e Adjust alignment to ensure full contact of magnet with
armature plate.
3f Carefully remove lock without shiing mounting bracket and
tighten panhead screws as needed to secure in place.
3g Secure mounting bracket in position with either nine (9)
TEK™ screws or four (4) at counter-sunk machine screws.
3h Drill ¾” (19 mm) wire access hole using mounting bracket as
a guide.
3i Tip the lock to expose the four (4) captive mounting screws.
LApply thread-locking compound to exposed
threads.
3j Slide the lock onto mounting bracket keyholes.
3k Tighten the four (4) captive mounting screws.
3l Insert anti-tamper plugs.
Retrofit installation:
3c Attach bracket to header with 9 TEK™ screws or four (4) at
counter-sunk machine screws utilizing holes from previous
installation.
LAdditional TEK™ screws may be used for added
strength.
3d Tip the lock to expose the four (4) captive mounting screws.
LApply thread-locking compound to exposed
threads.
3e Slide the lock onto mounting bracket keyholes.
3f Tighten the four (4) captive mounting screws.
3g Insert anti-tamper plugs.

6 Ensure instant release.
All switching devices must be wired between the DC power
source and the positive terminal of the lock as shown in Figure
4: Power Connections. Switching the negative power supply
line will not allow the lock to release immediately.
LThis lock contains TVS for surge suppression and
does not require any additional suppression.
LNote: Some warming of the device under routine
operation is normal.

Troubleshooting
Problem Solution
Cannot remove the lock mounting bracket
from top of magnet for installation.
Remove blocking screw. Insert supplied Allen wrench into mounting bolt holes in the
bottom of the lock housing and turn. See Figure 2: Lock Mounting on page 3.
Lock is installed but has no holding force at
all.
Check connections at power supply, connected releasing devices, lock terminals, and
lock circuit board to magnet core.
Lock has enough holding force to lightly
hold a screwdriver or set of pliers but door
will not lock.
Check to see that armature plate is correctly aligned with the electromagnetic lock. If
there is improper alignment, make a ⁄ ” turn of the armature plate mounting bolt and
check for alignment. Make sure to follow the armature plate mounting instructions
on the template and page 1 of these installation instructions.
Lock is operating and locking but the
armature plate is “humming” against the
surface of the lock.
This generally indicates that the lock is either operating on AC voltage or there is
some AC voltage present in the DC supply. A properly filtered and regulated DC
power supply is required to achieve optimal operation from the lock.
Lock is not releasing immediately upon
removal of power.
Ensure that switching devices are interrupting the DC power and not the AC power
supply voltage. Ensure rubber washer on armature plate mounting bolt has not been
removed or damaged. Check that switching device interrupts the positive wire and
not the negative wire. See Figure 4: Power Connections on page 4. Remove any
Diodes or other suppression devices that may be installed.
