Up to 32 keypads, each with a unique address, can
be connected to each keypad link on the
HomeWorks Interactive

300 keypad LEDs can be connected per processor.
The HWI-2B counts as 8 LEDs toward this limit. To
increase the number of LEDs, see the HomeWorks

Installation
1. Disconnect power to the keypads by turning off all
circuit breakers connected to the HomeWorks
Interactive
TM
power supply.
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 front of
the keypad. See Figure 3 (page 3) for DIP switch
location. See Figure 4 (page 4) for DIP switch
settings. Be sure to record the address for future
programming purposes.
3.
Strip insulation or trim wires to 3/8" (10mm). Each
terminal will accept one or two 18-gauge
2
(1.0mm ) wires.
4.
Unplug terminal block from the back of the
keypad.
5.
Connect wiring to terminal block as shown in
Figures 1 and 2 (page 3).
6.
Plug the keypad terminal block back onto the
keypad. Be sure to orient the terminal block
correctly.
7.
Connect to External Input Closures (optional).
The HWI-2B keypad accepts two low voltage dry
contact closures. Connect wiring for closures to
control if required. See Figure 2 (page 3).
®
When using the external input closures:
a. Verify compatibility of input devices. The
external input closures are intended for use
with devices that provide status in the form of
dry contact closure outputs. The external input
closures can be used with ground-referenced,
solid state outputs if the outputs have an on-
state saturation voltage of less than 2VDC and
an off-state leakage of less than 50µA. Dry
contact or solid-state outputs must be capable
of switching 5VDC at 10mA. The outputs must
stay in the closed or open states for at least
40msec in order to be recognized by the
keypad. If there is any question as to whether
the device is compatible with these specifica-
tions, contact the company that manufactures
it.
b. Configure the button assignment using DIP
switch No. 6 shown in Figure 5 (page 4).
8.
Mount keypad as shown in Figure 6 (page 4).
Do not over-tighten mounting screws.
9.
Restore power to the HomeWorks
