Installation Instructions
Overview
The STWD-1B, -2B, -3B, -3BRL, -4B, -4FS, -4S, -4SIR,
-5B, -5FS, -5BRL, -6B, -6BRL, and -7B keypads are for
use with HomeWorks systems. The keypad buttons
are programmed with a personal computer using the
HomeWorks Utility.
Up to 32 keypads, each with a unique address, may
be connected to each keypad link on the HomeWorks
processor. A maximum of 300 LEDs may be connect-
ed per processor. Each seeTouch keypad counts as
15 LEDs. To add capacity beyond 300 LEDs, refer to
the section about the HWI-PS in the HomeWorks
Technical Reference Guide (P/N 366-963).
Important Notes
Codes: Install in accordance with all local and nation-
al electrical codes.
Environment: Ambient operating temperature:
0-40°C, 32-104°F, 0-90% humidity, non-condensing.
Indoor use only.
Wallplates: Lutron Claro®and Satin ColorsTM
wallplates are recommended for best color match and
aesthetic appearance. Do not paint controls or
wallplates.
Cleaning: To clean, wipe with a clean damp cloth.
DO NOT use any chemical cleaning solutions.
Wallboxes: Lutron recommends using 3 1/2 in.
(89mm) deep wallboxes for easier installation.
Keypad Wiring: Keypad wiring may be in a daisy-
chain, star or t-tap configuration. Each home run on a
link may be up to 1,000 ft. (305m) and may contain up
to 10 keypad devices. The total length of wire on that
link (all home runs) may be up to 4,000 ft. (1220m).
Up to 32 keypad devices may be placed on each
processor link configured as a keypad link in the
HomeWorks Utility. An external power supply may be
required depending on the total current draw of all
keypad devices on the processor.

state saturation voltage of less than 2 VDC and an
off-state leakage of less than 50 µA. Dry contact or
solid-state outputs must be capable of switching
15 VDC at 10 mA. The outputs must stay in the
closed or open states for at least 40 msec in order to
be recognized by the keypad. If there is any question
as to whether the contact closure device is compati-
ble with these specifications, contact the manufactur-
er of that device.
9. Push all wires back into the wallbox and loosely fas-
ten the control to the wallbox using the screws pro-
vided. Do not pinch the wires. See Mounting
Diagram.
10. Attach Lutron®Claro®or Satin ColorsTM wallplate
adapter and wallplate.
a. Loosely install keypad mounting screws.
b. Tighten wallplate adapter mounting screws
snug.
c. Tighten keypad mounting screws until
wallplate adapter is flush to wall (do not over-
tighten).
d. Snap wallplate onto wallplate adapter, and
verify button kit is not submerged.
e. If button kit is submerged, loosen mounting
screws appropriately.
11. Restore power.

Mounting Diagram
1. Disconnect power to the keypads by turning OFF all
circuit breakers connected to the HomeWorks®
Processor or keypad link auxiliary power supply
(HWI-PS).
Wiring with power ON may result in
personal injury.
2. Remove currently installed button kit (if applicable).
Remove button kit from keypad by gently prying it
from the top. See Button Kit Removal.
3. Address keypads. Assign a unique address to each
keypad using the DIP switch settings. See Keypad
Addressing for DIP switch location and switch set-
tings. Be sure to record the address for future pro-
gramming purposes. Replace Button Kit.
4. Strip insulation to 3/8 in. (10mm).
5. Unplug keypad link terminal block from the keypad
circuit board.
6. Connect wiring to terminal block as shown in Wiring
Diagram (page 3). Each terminal will accept one or
two #18 AWG (1.0mm2) wires.
7. Plug the keypad link terminal block back onto the
keypad circuit board. Be sure to orient the terminal
block correctly.
8. Connect external input closures (if applicable). All
seeTouchTM keypads accept two low-voltage dry con-
tact closures (see Wiring Diagram - page 3).
When using the input closures:
Verify compatibility of external devices. The input clo-
sures are intended for use with devices that provide
outputs in the form of dry contact closure outputs.
The input closures may be used with ground-refer-
enced, solid-state outputs if the outputs have an on-

Troubleshooting Guide
Keypad is working properly when LEDs light up and loads respond as buttons are pressed.
Symptom Cause and Action
Power is not present at keypad.
• Make sure HomeWorks®processor is powered.
• Check for 15 VDC between pins 1 & 2 on the keypad connec-
tor.
• Remove connector from back of keypad, check connections
and replace.
• Check the HomeWorks Utility to make sure the keypad is pro-
grammed and addressed correctly.
Keypad is properly powered but is not communicating with the
processor.
• Verify that the processor is powered.
• Check that keypad wires 3 & 4 are properly connected.
• Check that keypad link is plugged into correct connector at
processor.
• Verify that link is configured for HWI keypads in the
HomeWorks Utility.
• Check keypad for proper address.
• Check system programming.
LEDs don't light up when buttons are pushed.
LEDs cycle from top to bottom sequentially.
LEDs light when pressed, but the system response isn't correct.
