Introduction
As a factory recognized installer for the Smoke Guard system, read this installation
manual to become familiar with all installation tasks before beginning. This manual tells
you what you need to know to install Model 200 and Model 400 smoke containment
systems from Smoke Guard.
About the Smoke Guard System
Smoke Guard manufactures a smoke-containment system for elevator hoistways. Under
alarm conditions, a screen drops from a housing to the floor, creating a seal around the
elevator opening that prevents smoke from traveling through the elevator shaft to other
floors.
The screen drops under either of two conditions:
°the smoke detector to which the housing is wired goes into alarm
°the power to the housing is cut off for several seconds
For information about the Smoke Guard System and building codes, see the Smoke
Guard Operation and Maintenance Manual.
About installation of the Smoke Guard System
Installation of the Smoke Guard system requires a moderate amount of construction
experience. Specifically, installation requires tools and materials listed on page 5 and
experience with the following:
°drilling through metal, sheet rock, and studs
°working with anchors appropriate for the wall and stud materials
°pop-riveting
°terminating low voltage wires
°understanding open and closed contacts
Installation occurs:
°after installation of the elevator frame
°after dry wall is mounted around elevator frame
°prior to ceiling installation
°prior to painting wall around elevator frame
NOTE: Follow standard safety procedures. Wear a hard hat and safety goggles, use
caution when working on a stepladder, get assistance when carrying and mounting the
housing, and use proper lifting techniques.

Preparing the Housing for Mounting
The screen assembly ships inside the housing. Remove the screen carefully to avoid
damage to
housing components.
To remove the screen from the housing:
1. With the return side against the floor, remove the dust cover and the door
clips.
2. Push the door open and gently roll the screen out through the housing door.
3. Unfasten machine screws holding the mounting plate and remove plate.
NOTE: The door closer extension springs
(Model 400 only) and the uplimit switch are
not attached in their operating positions when
we ship the unit. This allows you to remove
the screen safely. Later in the installation
process you will attach them in their proper
positions.

Installing the Mounting Plate
Install the mounting plate for the housing on the wall over the elevator frame.
System component:
mounting plate
Tools/Materials:
°safety glasses
°25 foot measuring tape
°hand drill
°permanent marker
°torpedo level
°4 foot magnetic level
°6 wall anchors, drill bit, and
driver (see the appendix for
recommended anchors)
NOTE: Anchor mounting plate LEVEL and FLAT..
To install the mounting plate:
1. Mark the mounting height over the elevator opening.
2. Mark the center of the elevator frame at mounting height and a centerline on the
mounting plate.
3. Lift the mounting plate and place against the wall, bottom edge 3/4” above
mounting height.
4. Temporarily anchor in place through center hole near top of plate.
5. Level the plate and shim to assure a FLAT surface.
6. Anchor the plate to the wall through 6-8 of the holes in the plate.
9

Mounting the Housing
The housing hooks over the top of the mounting plate and fastens to the plate with
machine screws through threaded standoffs.
System component:
housing (dust cover and screen assembly removed, see page 8)
Tools/Materials:
5/32” hex wrench
NOTE: Always keep your head higher than the housing while mounting. This makes the
job easier and helps to avoid head injury.
To mount the housing:
1. 1Lift the housing onto the mounting plate. Hook the lip on the housing over the
mounting plate as illustrated below.
2. Adjust the position of the housing so the center mark inside the housing meets
the center of the elevator frame.
3. Verify that slots in the back of the housing line up with the threaded standoffs as
illustrated below.
4. Fasten the housing to the mounting plate by reinserting the machine screws
through the threaded standoffs.

Installing the Auxiliary Rails
When the unit deploys, the smoke containment screen unrolls out of the housing to the
floor. Flexible magnets along the edges of the screen seal the elevator opening by rolling
down and adhering to either the elevator frame or to auxiliary rails.
Use auxiliary rails if the elevator frame is:
°nonferrous (stainless steel, brass, bronze, aluminum)
°not flat
°less than 2 inches wide
°recessed or flush with the wall
If the elevator frame is made of a metal that will attract the magnets, install stub rails
extending from the top of the elevator frame to the bottom of the housing. (Stub rails are
not required if the gap between the head of the doorframe and the housing is 1/4 inch or
less.)
NOTE: When measuring for the length of the rails, take into consideration the thickness
of the flooring that may be added later. If possible, obtain a sample of the flooring to
place on the floor when you perform the following steps.
System Components:
°rail backer(s)
°rail(s)
Tools/Materials:
°safety glasses
°sample of flooring
°25’ measuring tape
°permanent marker
°hand drill
°12-16 wall anchors, drill bit,
and driver appropriate for the
material
°3 foot level
°tin snips
°hacksaw
°pop riveter
°1/8 inch stainless steel rivets
The auxiliary rail backers attach the auxiliary rails to the wall along the sides of the
elevator frame, or in the case of stub rails, between the head of the elevator frame and
the housing.
To anchor the auxiliary rail backers:
1. If using full auxiliary rails, measure the distance between the floor and the bottom
of the housing.
OR
If using stub rails between the housing and the head of the elevator frame,
measure the distance between the two.
2. Use the measurement to cut the rail backers with tin snips.
12

3. For full auxiliary rails, drill 5 to 6 evenly
spaced holes on each rail backer for
wall anchors.
OR For stub rails, drill a minimum of 2
holes (even for short stub rails).
TIP: Drill holes within 1 inch of each end
of the rail backer.
4. Align the center of a rail backer with the
right rail backer centerline marked inside
the housing, as illustrated:
5. Level the rail backer vertically.
6. Mark and drill anchor holes through the
wall (lining them up with the holes that
you drilled through the rail backer).
7. Drive anchors through the drilled holes.
8. Repeat steps 4-7 for the left rail backer.
Mount the auxiliary rails so they are flush with the bottom of the housing return and the
elevator frame. The auxiliary rails are the most visible hardware of the unit. Any damage
to the rails affects the seal and appearance of the unit. For this reason, cut the rails with
a hacksaw, NOT tin snips.
To pop-rivet the auxiliary rails:
1. 1. Measure along the right rail backer to find the distance between the floor and
the bottom of the housing.
2. Use the measurement to cut a rail, using a hacksaw for a clean edge.
3. Repeat steps 1 and 2 for the left rail.
4. Drill several evenly spaced holes along the outside return edge of each rail.
5. Mount the rails over the rail backers, placing the FACTORY CUT edge against
the housing.
6. Slide each rail up its rail backer until the rail is flush with the bottom of the
housing and flush against the wall.
7. Drill the rail backer through the
holes drilled in step 4.
8. Rivet the holes while holding the
rail flush with the housing and the
wall.
9. Verify that the rails are vertically
level.
13

Attaching the Extension Springs (Model 400 only)
When Smoke Guard ships Model 400 units, the door closer extension springs are not
attached to the door in their operating position. This allows you to remove the screen
from the housing safely.This point in the installation process is ideal for fastening the
springs to the door.
To attach springs to the door:
1. Close the housing door.
2. Tighten the thumb nuts on the ends of the extension springs over the studs on
the housing door:

Installing the Screen
Installing the screen involves the following tasks:
°Attach J-clips: Magnetic screen setting brackets, called J-clips, attach to the rails
or frame.
°Set the screen: Support the screen with the J-clips while you secure the top bar
inside the housing.
°Attach the threshold cables: Drop two Kevlar cables wrapped inside the housing
and attach them to the threshold spools before dropping the screen to the floor.
°Attach the uplimit switch: Cut the zip ties temporarily holding the uplimit in its
shipping position. Fasten the switch to its bracket.
System components:
°screen °2 J-clips
Tools/Materials:
°safety glasses
°hand drill
°5/16” hex
driver
°drill point screws provided
°120 VAC extension cord with
ground
To attach J-clips:
°line up the tops evenly with each other, at least two
inches below the housing
°line up the J portion on the outside
edge of the rail, as illustrated:
CAUTION: Clean the magnets on the J-clips of debris to
avoid scraping the frame. Attach and remove carefully.
15

To set the screen:
1. Lift the screen onto the J-clips so the screen unrolls from the back of the roll.
2. Remove the nut from the center stud.
3. Lift the top bar of the screen to unroll it up into the housing far enough to fit its
center hole over the center stud and reattach the nut.
4. Grab the magnets on each side near the top bar and pull sideways until the
screen is taut.
5. Screen overlaps rails (or side of the elevator frame) by 1/4” on each side.
16

To attach the threshold cables:
1. Remove the tape holding the cable wraps on the drive pulleys in the housing.
2. Unwind enough cable to reach the threshold spools.
3. Work each cable through the slot in its threshold spool and pull the cables up,
lodging the crimp beads snugly in the holes:
4. Wrap cable twice around each threshold spool, over the top toward the wall, as
illustrated:
5. Turn one of the drive pulleys inside the housing to take up any slack in the
cables.
17

To attach the uplimit switch:
1. Cut the zip ties holding the uplimit switch in its shipping position.
2. Fasten the uplimit to its bracket on the left side of the lower, front support bar.
