Introduction

About the HSA 822M Hideaway® Enclosures

The Extron HSA 822M is a furniture-mounted, motorized, architectural solution for inconspicuous computer video interface connector access and control.

The HSA 822M (figure 1-1) provides space for four double space (double-height) 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 version with US power outlets and an international version with several different types of power outlets, including Universal, UK, French, Israeli, Australian, Indian, European, and Swiss receptacles.

The Universal AC outlet is fully compatible with Europlug, British, Indian, Danish, and Italian plug types. See the Universal AC outlet guide on the Extron Web site, www.extron.com, for compatibility details on all plug types.

Closed

A cable inside the enclosure connects the user AC receptacles to a power 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.

The functionality of the HSA 822M can be optimized with one through four RGB 580xi AAPs connected to one through four RGB 580xi Remote Interfaces (figure 1-2).

Figure 1-1 — HSA 822M hideaway enclosure

The motorized action is 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 installed enclosure fits nearly 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, sends 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.

Preparing the Routing Template

Extron offers a metal template, part #70-191-01, for the HSA 822M and HSA 822. Extron recommends using this template as a guide to cut the hole in the table where the HSA will be installed.

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

1. Cut 1/2" x 4" strips of soft, finished lumber long enough to

span the distance between the desired installation location on the table or other mounting surface and the edges of the table (figure 2-2).

Minimum 4 Screws

Mounting Surface Edge

Wood Strips

Wood Strip Height 4" / 10.2 cm

Preparing the Table

The preferred and recommended method for preparing the table is to use the appropriate Extron metal routing template and a router.

Alternatively, you can use a paper cut-out template (see appendix A, “Reference Information”) and a sabre saw or keyhole saw, but this method is not recommended.

Prepare the table as follows:

CAUTION

The opening in the table for the HSA 822M should be cut only by licensed and bonded craftspeople. Exercise care to prevent scarring or damaging the furniture.

The routing templates for the various HSA models are not interchangeable. If you use the wrong template, you will cut an improperly-sized hole. If you use a larger template than required, the cut will result in gaps in the table surface on either side of the enclosure.

The surfaces of the HSA enclosure have screws and other protruding hardware that could damage fine furniture. Do not rest the enclosure on unprotected furniture.

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

Figure 2-2 — Prepared mounting template

These strips raise the routing template above the mounting surface to provide room for the router’s collar, protect the mounting surface, and extend the reach of the routing template so that it can be clamped to the edge of the surface.

2. Using four or more short wood screws, secure the

mounting template to the lumber strips.

CAUTION

HSA 822M • Installation

Routing T emplate

Do not allow the wood screws to protrude through the bottom of the wooden strips. Protruding screws will mar the table when the template is used.

The HSA 822M mounts in exactly the same size hole as the HSA 822 and uses the same metal mounting template.

1. Locate the desired mounting location on the tabletop or

other installation surface. Mark the location.

CAUTION

Ensure that only the wooden strips contact the furniture. Failure to do so may mar the furniture.

2. Place the mounting template assembly on the table,

centered on the mounting location. Angle the template for the optimum positioning. If necessary, use a square to ensure that the template is properly positioned. Extron is not responsible for improperly-positioned HSA products.

3. Once the template assembly is positioned properly, use

C-clamps to secure the assembly to the table for routing as shown in figure 2-3 on the next page.

Figure 2-3 — Cutting the opening with a router

4. Using a router with a 5/8" (or 16 mm) outside diameter

guide bushing and a 1/2" (or 12 mm or 12.7 mm) diameter straight router bit, carefully cut the opening in the table surface (figure 2-3).

5. Remove the C-clamps and the routing template.

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

The flanged edges of the top of the surface enclosure are sharp when the HSA is not installed in a table. Exercise caution when handling to prevent personal injury.

7. Carefully lower the HSA enclosure into the hole to test the

fit. If necessary, remove the enclosure and use a file or rasp to enlarge or smooth the edges of the opening.

Cabling and Installing the AAPs

The space behind the AAP panel is limited. The online Connectivity Configurator, available at

www.extron.com, offers guidance as to the fit of AAPs

into this space.

Extron’s various single space and double space AAP devices, including the various RGB 580xi AAPs, can be mounted to the HSA 822M. 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. Remove the top and bottom screws on the right and left

sides of the AAP/RJ-45 panel (figure 2-4). Retain the screws. Lift the panel away from the enclosure as far as the connected cables allow and then allow the panel to dangle, supported by its connected cables.

Remove two

screws ea. side.

CAUTION

The flanged edges of the top of the surface enclosure are bevelled to an ultra-fine thickness of less than

0.04 (4/100)" (approximately 1 mm). These edges are soft and can be easily nicked or bent. Exercise caution when handling and mounting the enclosure. Mishandling can damage the appearance of the enclosure.

6. Remove the rubber strip that protects the top surface’s

flanged edges. If a sticky residue remains, remove it with an appropriate metal cleaning product.

CAUTION

Do not use isopropyl alcohol or other solvents to clean the HSA. Strong solvents will ruin some finishes.

Routing the AAP Cables and Installing the Clamshell

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 secure the AAP cables as follows:

1. Manually open the top panel to extend the AAP cables to

their maximum pull.

2. To prevent wear and tear or binding of the mechanism

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 (figure 2-6).

Safety Switch — Location Only

The safety switch (figure 3-10) 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. The carriage typically reverses with less than twelve pounds of pressure applied to the obstruction.

The HSA 822M mounts in exactly the same size hole as the HSA 822 and uses the same metal mounting template.

If you choose not to use metal routing template available from Extron, the cut-out template (figure A-3 on the next page) will help you properly prepare the mounting surface. The cutout template is not to scale and is for reference only. The surface cut-out area dimensions for the template are marked in bold type.

The HSA 822M mounts in exactly the same size hole as the HSA 822 and uses the same paper cut-out template.

Packaging for Shipment

CAUTION

Installation and service must be performed by authorized personnel only.

The HSA 822M’s ultra-fine machined surfaces and moving parts make them vulnerable to damage caused by mishandling during shipment if they are improperly packaged. If, for any reason, you need to return an HSA to Extron, first contact Extron to obtain a return kit. The return kit, which reduces the chances of damage during shipment, includes a sturdy shipping carton, shipping restraints, and foam cut to fit the HSA (figure B-1).

2. Disconnect all cables, remove any AAPs, and remove the HSA 822M from the table or desk. See “Removing and Replacing the Enclosure”, steps 1 through 11, in chapter 3, “Maintenance and Modifications”. Place the enclosure on a horizontal surface. To protect the finish, place the enclosure on a soft cloth or rubber mat.

3. With the platform fully extended, insert the yellow shipping restraints through the slotted holes in one side of the enclosure’s shroud (figure B-2) and out the holes in the opposite side. Use the included tie-wraps to secure the shipping restraints in place.
