Introduction

About the HSA 822MS Hideaway Enclosures

The Extron HSA 822MS is a furniture-mounted, motorized
architectural solution for computer video interface connector
access and control. The top (table) surface of the HSA can be
made from the portion of the furniture that is removed for the
HSA installation to provide an inconspicuous appearance
(figure 1-1).

Preliminary

Closed

The installed enclosure fits flush within a table or podium top,
storing the AAPs and connectors out of the way and out of
sight. To access the AAPs and connectors, the user touches a
button, send s a control system command, or presses down on
the top of the enclosure. A stepper motor slowly raises the
AAPs and connectors into view.

The AAP spaces and RJ-45 connectors are arranged back-to
back, while the AC receptacles are back-to-back on the sides
perpendicular to the AAPs.

A cable inside the enclosure connects the user AC receptacles to
an IEC connector on the underside of the enclosure. The same
power cable supplies the stepper motor that drives the panel up
and down.

Cables inside the enclosure route the front panel RJ-45 signal
lines to RJ-45 connectors on the underside of the enclosure.
With an optional conversion kit, one or more of the RJ-45 (data)
lines can be converted to an RJ-11 (telephone) line.

Preliminary

Open

Figure 1-1 — HSA 822MS hideaway enclosure

The HSA 822MS provides space for four double space (double­height) or eight single space Extron Architectural Adapter Plates
(AAPs), two standard grounded AC power receptacles, and four
RJ-45 (Category [CAT] 6) connectors. The HSA is available in a
US version, with US power receptacles, and an international
version. Several different types of power receptacles are
available for the international version, including UK, French,
Israeli, Australian, Indian, European, and Swiss receptacles.

The motorized action is remotely controlled by contact closure.
The control mechanism uses discrete high or low signals to
report the HSA’s up or down position. Safety devices prevent
injury and equipment damage.

The preferred and recommended method for preparing the
table is to have the hole cut to the exact dimensions identified in
appendix A by a reputable carpenter or other craftsman.

Preparing the Table

CAUTION

Preliminary

The preferred and recommended method for preparing the
table is to have the hole cut to the exact dimensions identified
in appendix A by a reputable carpenter or other craftsman. Save
the removed material or fabricate a piece of the same material
that is the same size of the removed material for use as the top
surface of the HSA.

The opening in the table for the HSA should be cut
only by licensed and bonded craftspeople. Exercise
care to prevent scarring or damaging the furniture.

When selecting a mounting location, be aware that the
HSA 822MS is not exactly square. The cable and AAP
access is on the 6.220" (15.80 cm) side. Angle the cut
for the optimum positioning. If necessary, use a square
to ensure that the cut is properly positioned. Extron is
not responsible for improperly-positioned HSA products.

The levelling adjustment allows the HSA to be installed
in a table with a thickness between 3/4" (1.9 cm) and

1.5"(3.8 cm).

For best results, the surface block dimension should be
1/32" to 1/16" (1 mm) smaller on all four sides than the
cutout hole.

Preliminary

Figure 2-2 — Using the drilling template

4. Remove the drilling template. Keep the template for

future installations.

Preparing the HSA

1. Set the HSA 822MS on its side on a work surface.

2. Cut the tie wraps that lock the yellow shipping restraints

in place and remove the restraints (figure 2-3).

The metal drilling template is reusable. Do not discard
this template when the installation is complete. Save it
for future HSA 822MS installations.

1. Turn the table upside-down.

CAUTION

2. Place the metal drilling template into the hole in the table.

The drilling template should fit snugly into the hole, with
no noticeable sideways or top-to-bottom motion.

3. Drill pilot holes, each 3/32" (2.4 mm) in diameter by 1/4"

(7 mm) deep, at each of the template’s eight standoff
guides (figure 2-2).

Protect the table surface.

The metal drilling template should fit snugly in the hole.
If the template can move, the hole size is too large.

Wear safety glasses when operating the drill.
Failure to heed this warning can result in eye injury .

secure the top plate to the surface block.

HSA, step 10, secure the top plate to the lifting plate
(figure 2-10). Leave the nuts slightly loosened for
adjustment.

The surface block can fit either of two ways. For surfaces
with a grain pattern, check that the pattern of the surface
block is the best match for the grain pattern of the table
surface. If necessary, reverse the direction of the block.

Making Final Adjustments

1. On the 10-pin control and status captive
screw connector on the underside of the
HSA, use a piece of wire to temporarily
jumper pin 4 to pin 5 to enable the manual activation
(press to activate) operation of the HSA.

2. With the unit unpowered, gently press on the surface
block to retract (close) the unit. The surface block should
fit snugly within the cut-out hole.

If the surface block impacts the sides of the hole, adjust
the positioning of the HSA and the surface block. With the
installation screws and nuts left slightly loosened, the HSA
and/or the surface block should be able to be moved
enough for the surface block to fit snugly. Leave the
installation screws and nuts left slightly loosened.

2. Connect the enclosure to the appropriate power source:

• 125 VAC, 60 Hz, 5 A (US domestic version)

• 220-240 V, 50/60 Hz, 5 A (international versions)
The HSA moves to its home (retracted) position, close to

flush with the table surface.

4. Check that the surface block is horizontal, and not tipped
to one side or the other. If necessary, adjust the surface
block to be horizontal as follows:

a. Slowly tighten the adjustment screw, on the under-

side of the top plate (figure 2-11), that is closest to the
lowest side of the surface block to raise that side.

repeat step 5d.

g. When the surface block is flush with the table surface

to your satisfaction, tighten the lower limit switch

6. Check that the surface block is centered in the cut-out hole.
If the surface block is not centered in the hole, adjust the

positioning of the surface block. With the installation
screws and nuts left slightly loosened, the HSA and
surface block should be able to be moved enough for the
surface block to be centered.

When the surface block is satisfactorily centered in the
hole, tighten the four 1/4" nuts that secure the top plate to

the lifting plate (figure 2-6 on page 2-7).

7. Tighten the eight #8-32 wood screws that secure the HSA

frame with the eight screws per shroud half (four per side)
that you removed in Preparing the HSA, step 3. Orient the
shroud halves such that the vertical column of center holes
align with the column of screw inserts on the vertical
slides.

Cabling and Installing the AAPs

Extron’s various single space and double space AAP devices,
including the various RGB 580xi AAPs, can be mounted to the
HSA 822MS. See appendix A, Reference Information, for
RGB 580xi AAP part numbers.

The screws for installing an AAP are built into its AAP/RJ-45
panel, so no additional screws are needed.

Ensure that AC power is disconnected before
servicing the HSA unit.

1. Cable the rear of the AAPs before fastening the AAPs to
the AAP/RJ-45 panel. Route the cables through the hole in
the underside of the surface mount enclosure and connect
them to the rear of the AAPs. If applicable, refer to the
cabling information in the documentation for the AAP.

2. Remove the blank AAPs in the HSA AAP/RJ-45 panel by

removing the four #4-40 nuts and captive washers.

3. Insert each of the AAP’s screws through the holes in the

AAP opening of the HSA AAP/RJ-45 panel. Secure each
AAP to the panel with the provided captive washers and
#4-40 nuts (figure 2-13).

Figure 2-13 — Mounting an AAP on the AAP/RJ-45
panel

4. Replace the AAP/RJ-45 panel in the surface mount

enclosure and secure it in place with the screws removed
in Preparing the HSA, step 6. If you lose an AAP/RJ-45
panel screw, four spare screws are stored in the underside
of the enclosure (figure 2-15 on page 2-18, item 5).

Routing the AAP Cables

The AAP cables must have freedom of movement to permit
opening and closing the surface mount enclosure. At the same
time, they need to be restrained to prevent them from rubbing
against the edges of the enclosure cable access hole in the
underside of the surface mount enclosure. Rubbing against the
cable access hole edges can damage the cables. Route and

Preliminary

secure the AAP cables as follows:

1. Connect the enclosure to the appropriate power source:

• 125 VAC, 60 Hz, 5 A (US domestic version)

• 220-240 V, 50/60 Hz, 5 A (international versions)

2. Press on the surface block to open the top panel and
extend the AAP cables to their maximum pull.

3. To prevent wear and tear or binding of the movement
caused by cable movement, secure the AAP cables inside
the enclosure. Use tie wraps to secure the cables to the tie­downs accessible through the cable access holes on the
underside of the HSA (figure 2-14).

4. On the underside of the HSA, remove the
jumper from the 10 pin control and status
captive screw connector.

(Elevated Platform Height)

This switch’s position is properly set in the factory.

The upper limit switch sets the stop point for the raised
platform. If the switch is set too low, the platform does not rise
high enough. If the switch is set too high, the motor attempts to
raise the platform past the mechanical stop and then lowers the
platform to the recessed position. Set the platform’s height as
follows:

1. Remove the shroud. See Removing and Replacing the
Shroud, on page 3-6, step 1.

2. Activate the motor to raise the platform. Leave AC power
applied to the HSA.

Safety Switch — Location only

The safety switch (figure 3-9) stops the downward motion of
platform when it encounters an obstruction to its smooth
operation. If an obstruction is present that blocks the platform’s
travel, the stepper motor’s carriage lifts and activates the safety
switch. The HSA’s motor logic automatically reverses the
platform’s motion and raises the platform to the upper position.

Preliminary

The carriage typically reverses with less than twelve pounds of
pressure applied to the obstruction.

Replacing the Control Board Assembly and
Power Supply Assembly

The control board assembly (figure 3-1 on page 3-2, 1) and the
power supply assembly (2) can be replaced, if necessary, as
follows:

1. Disconnect AC power.

2. Remove the shroud. See Removing and Replacing the
Shroud, on page 3-6, step 1.

3. From the underside of the enclosure, reach into the cable

access holes (figure 3-1 on page 3-2, item
tie wraps (5 shows the tie-downs) that route the AAP
cables and network (CAT 6) cables inside the enclosure.

4. Remove the three screws (figure 3-1 on page 3-2, item
that secure the assembly to be replaced to the underside of
the enclosure.

For the control board assembly, screws indicated by an
asterisk (*) on figure 3-1 are accessible from the top
(inside the enclosure).

Do not remove screw X (figure 3-1 on page 3-2).
This screw does not secure the power supply assembly in
any way; rather, it provides structural support to the
enclosure.

5. Remove all connectors from the assembly to be replaced.

6. Remove the assembly from the enclosure.

7. Secure the replacement assembly in the enclosure with the
screws removed in step 4.

8. Reconnect all connectors removed in step 5.

9. Retie all of the network (CAT 6) and AAP cables removed

in step 3 to the tie-downs (figure 3-1 on page 3-2, item 5)
on the assembly that was replaced.
