Operation/Standard Feature s/Available Options
Operation:
A shear lock is designed to rely on the shear strength of steel for holding force. A strong
magnet is energized that attracts an armature which overcomes an air gap to engage with
the magnet. The magnet and the armature, besides being bonded by magnetic force, are
also designed to mechanically interlock. This gives the system 3000 pounds of holding
force. Because of this design, precise door and frame preparation is necessary. Also
important is that the centerlines of the magnet and armature line up to form a vertical axis.
It is also critical that the air gap be adjusted to be as close as possible without interfering
with door operation. This ensures the best reliability possible.

Installing a GF3000 Series Lock
Preparing the Frame and Door
1) Establish Frame and Door Centerlines (Standard and TRD):
• For proper operation, it’s critical to establish centerlines of magnet and armature assembly
that line up to form a vertical axis. The figure below shows the centerline scheme for a stan-
dard GF3000 and a GF3000TRD. Note that centerlines for magnet (M1 and M2) are directly
above centerlines for armature assembly (A1 and A2) thus forming a vertical axis (AM).
• Check door & frame for any structural member or hardware component that might interfere
with magnet and armature mounting areas before selecting template location.
• Remove existing hung doors for template application and armature installation.
• The standard model GF3000 can be installed in a horizontal or vertical configuration.
• To achieve maximum resistance to forced entry, position as follows:
> Horizontal configuration - position unit closest to the latch side of door.
>Vertical configuration - positioning unit closest to the strike plate is recommended.
• In some applications, the door and frame may require reinforcement.

1) Establish Frame and Door Centerlines (BRD):
• For proper operation, it’s critical to establish centerlines of the magnet and armature
assembly that line up to form a vertical axis. The figure below shows the centerline scheme
for a GF3000BRD. Note that centerlines for magnet (M1 and M2) are directly below
centerlines for armature (A1 and A2) thus forming a vertical axis (AM).
• To achieve maximum resistance to forced entry, position unit closest to latch side of door.
• Adjusting screw must be accessible with a long bladed screwdriver when door is hung.
• Check both door & frame for any structural member or hardware component that
might interfere with magnet and armature mounting areas before selecting
template location.
•Existing hung doors will normally have to be removed for template application
and armature installation.
• In some applications, the door and frame may require reinforcement.

Installing the Lock - BRD
•INSTALLING THE MAGNET AND ARMATURE
1) Preparing the Floor for the GF3000BRD Magnet:
Since the GF3000BRD magnet is installed in the floor directly below the bottom rail of the door, a
threshold box (that will hold the magnet) that is inset into a pocket (
a) in the floor, and a trench
(
b) for the electrical conduit is required.
NOTE: Retrofit Installations - You may find that conditions vary from site to site after the
threshold plate (c) is removed. If a cement, stone, or other hard material is encountered, using
a pavement breaker or demolition hammer might be useful for chiseling out the pocket
and trench in the floor.
Using tools applicable for conditions found at the site, create a pocket that is at least 2.375” wide x 7.5”
long
within the threshold area, centered directly below door’s bottom rail and furthest away from
hinges.
Depth
of this pocket (d) may vary from site to site. The guiding dimension for depth of the pocket is dis-
tance
(e). Distance (e) is from top of the threshold box that is in set into the pocket to the underside of
the threshold plate.
IMPORTANT: Considerations to keep in mind for position of metal box are:
> When magnet and threshold are installed, magnet must not protrude above threshold.
> You should be able to use box’s shim washers to raise and lower magnet to proper level.
>Box centerline (f) must be placed on centerline of door.
The
trench for the conduit should be at least 1/2” wide and deep enough so that the conduit
can
be easily inserted into the 7/8” hole in end of box. Direction and length of the trench
away
from the metal box may vary from site to site.

in the Door’s Bottom Rail:
After the pocket and trench are created, do the following:
• Feed 1/2" conduit into either 7/8" diameter hole in threshold box.
• Secure conduit with nut.
• Position box in pocket and conduit in trench.
• Pour concrete around threshold box and conduit and allow to cure.
•Mount armature mounting bracket assembly (a) to bottom rail using #10-24 x 3/4"
Pan head screws (b) supplied.
• Mount armature assembly (c) to armature mounting bracket assembly (a)
•Remove end cap on door to expose adjusting screw (d). If door doesn't have a
removable end cap, an access hole will have to be drilled in edge of door according
to the approximate dimensions as shown.

•Mount magnet (a) to box (b) by placing two speed nuts (c) per slot, side by side in
flanges of box.
•Line up magnet over speed nuts. Insert #10-24 x 1/2" flat head screws (d) into
magnet brackets and through speed nuts.
Align magnet, making sure centerlines of
armature are on the centerlines of magnet. Tighten screws.
• If needed, add shims under magnet to bring magnet flush with top of threshold.
NOTE: Top surface of magnet must not protrude above top surface of threshold.
• Replace door on hinges.
• Adjust armature, using adjusting screw located in access hole so that the clearance
gap of approx. 1/16" between magnet face and armature is achieved. It may be
necessary to slightly re-adjust the gap to achieve proper locking action and spring
return action when the magnet is de-energized.
• If door’s bottom raildepth is greater than 1-3/4", spacers (e) may be needed
(one, 1/8" thick spacer is supplied).
• Install door status switch into frame and actuating magnet into door (see Door
Status Monitor (DSM) - GF3000BRD on page 23.).
• After all magnet adjustments have been completed, it is strongly recommended to
fill the magnet box with a spray urethane foam insulation (available from most
building supply companies) to keep water out.
• Make final wiring connections (see Wiring Diagram: on page 22.
NOTE: Mount Control Module (f) in a remote and dry location, and no more than 15
feet away from lock.
