ACCESSORY INSTALLATION SUPPLEMENT
Door Limit and Magnetic Reed Switches
1. Mars door limit and magnetic reed switches are
available with NEMA 1, 4X and 7 ratings. Contact the
factory for additional ratings and details. (See FIG. 1
for typical single swing, hinged door type, door limit
switch installation)
FIG. 1
2. Use light gauge materials when field fabricating
brackets to activate and deactivate the door limit
switch(s). (FIG. 2) Figure 2 also shows the typical
installation of the combination plunger/roller type
NEMA 1 door limit switch, for all non-hinged style
doors.
FIG. 2
3. All wiring must be per local and NEC (National Electric
Code) codes.
4. Panels or controllers may be required. Refer to wiring
diagram inside the control panel box.

Bracket Installation
1. Side Extension Plates: For doorways wider than the air
curtain, use combination of Side Extension Plates and
Adjustable Mounting Brackets. (FIG. 5)
FIG. 5 (LPV SHOWN)
2. Adjustable Mounting Brackets: For installation of air
curtain over drum-style roll-up door, use Extended
Wall Mounting Brackets. (FIG. 6)
FIG. 6 (STD SHOWN)
3. Extended Wall Mounting: For Tandem Mounting of air
curtain over sectional style door, use either wall
mounting angle brackets or threaded rods.
4. Top Mounting Brackets: For overhead installation of
units, use in conjunction with the threaded holes
provided on top of unit.
Note: Angle brackets, threaded rods and I Beams are
provided by others. (FIGS. 7 & 8) All optional brackets
are not available for WMI/WMH and BD Series.
