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.
