Use of the MXD permits delayed exit without the need to alter the existing door latch and
hardware. The relatively large door movement that it supports (up to one inch) eliminates the
potential problem of false triggering if the door is rattled or subjected to wind loads. It is also
highly tamper resistant in the event that someone would wish to defeat its safety function of
allowing people to exit.
2. PHYSICAL INSTALLATION
2.1 DETERMINING HORIZONTAL OR VERTICAL MOUNT AND APPLYING TEMPLATE
The MXD can be mounted
horizontally
under the frame header or
vertically
along the frame.
Once you have
selected the orientation
for your installation, apply the template to set your
hole drilling positions. To apply the template, close the door (be
sure it latches
) and note that
the template has a folding line on it. The magnet mounting “sub-plate” is on one side of the line
and the strike plate/permanent magnet bracket is on the other. Position the fold in the template
along the edge the door stop makes with the door surface so that the sub-plate portion of the
template extends on to the door stop and the strike/permanent magnet bracket portion extends
on to the door surface. If you have a
swing through type aluminum frame glass door
, there
is no door stop so you simply position the template fold line on the edge between the door
surface and frame stile. In planning your installation for this type of door, a special
consideration comes into play. First, before drilling any holes, you want to
be sure that the
aluminum door rail is wide enough to support the sex bolt
. The MXD sex bolt is 1” (25MM)
diameter which is much thicker than normal magnetic lock sex bolts. This type of door is made
with extrusion widths which vary widely but some are so narrow that you can only mount the
MXD sex bolt when you are using the model 32 lock. Some others will accept a model 62 lock
but only when you are using the offset strike.
To determine in advance whether your door and the Magnalock that you intend to use will
accept the MXD sex bolt, just hold the template so that you can visually see the center point of
where the sex bolt will go into the door rail. Assure yourself that a 1” diameter hole around this
point will not strike the glass or any support rods internally.
Note: if you have an aluminum frame glass door
with a blade stop
, see the next section as the
template is used differently. Otherwise, the template will work on horizontal or vertical mounts
and on left hand or right hand doors but be sure that the edge of the template is flush to the
corner of the door stop for best mounted appearance (the MXD housing will reach to the corner
of the door stop).
Tape the template into position and using a center punch, mark the hole locations on the door
and frame. The template will indicate the number and positions of the hole locations as well as
the hole diameters. This depends on which Magnalock type is being used. Note that if the
door
stop is narrow
, you may need to add a filler plate to create a wide enough mounting surface for
the sub-plate.
2.2 TEMPLATE USE ON AN ALUMINUM FRAME GLASS DOOR WITH BLADE STOP
A
blade stop is so narrow
(around 1/8”) that nothing can be mounted on it. Therefore, you
cannot place the folded edge of the template in the corner made by the stop and door surface
as you will not be mounting on the stop. You will be mounting the sub-plate
adjacent to the
stop
directly on the frame extrusion. To use the template in this exceptional situation, cut it with
a scissors along the fold line. To mark the strike plate/permanent magnet bracket holes, open
the door slightly and insert the template behind the blade stop until it just touches the door
frame. Then allow the door to fully close (this will capture the template). You can then
