Installation Instructions
Overview
The HWS-3B and HWS-4B are for use with
HomeWorks systems. The keypad buttons are pro-
grammed using the HomeWorks Utility.
Up to 32 keypads, each with a unique address, can be
connected to each keypad link on the HomeWorks
processor. A maximum of 300 keypad LEDs can be
connected per processor. Each HWS-3B keypad
counts as 6 LEDs, and each HWS-4B keypad counts
as 8 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
national electrical codes.
Environment: Ambient operating temperature:
0-40°C, 32-104°F, 0-90% humidity, non-condensing.
Indoor use only.
Cleaning: To clean, wipe with a clean damp cloth.
DO NOT use any chemical cleaning solutions.
Wallboxes: Signature Series keypads may be mount-
ed in a door jamb without a wallbox, or mounted in a
wall using a special wallbox (Lutron Model # WBOX-
SA1-Q1, purchased separately). See Mounting
Diagram (page 2).
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. (305 m) 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. (1220
m). 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.

Installation
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. Address keypads. Assign a unique address to each
keypad using the DIP switch on the back of the key-
pad. See Keypad Addressing (page 3) for DIP switch
location and DIP switch settings. Be sure to record
the address for future programming purposes.
3. Strip insulation from wires to 3/8 in. (10mm). Each
terminal will accept one or two #18 AWG (1.0 mm2)
wires.
4. Unplug keypad link terminal block from the keypad
circuit board.
5. Connect wiring to terminal block as shown in Wiring
Diagram (page 3).
6. Plug the keypad link terminal block back onto the cir-
cuit board. Be sure to orient the terminal block cor-
rectly.
7. Mount keypad as shown in Mounting Diagram. Do
not over-tighten mounting screws.
8. Restore power to the HomeWorks Processor or key-
pad link auxiliary power supply.
