Keypad Setup
The keypads (Model ENC-DRS) are wired to the hub with Cat-5
cable. Each keypad contains a Class-D digital amplifi er and
connects to a pair of stereo speakers.
Power for the keypad is normally supplied from the hub through the
Cat-5 cable. As an option to support longer cable runs and to prevent
voltage drop, the hub provides four
HI POWER
output terminals. The
HI POWER
terminals support 2-conductor 16-gauge wire, and are
recommended for keypad installations greater than 150’ from the
hub or where maximum amplifi er output will be required. See the
table below for keypad power ratings and wiring lengths.

Each keypad can connect to a local input wall plate (Model
ENC-LIWP). The local input wall plate can be used for an audio
source connection at the keypad’s location. See the next section
for installation of local input plates.
Keypad Installation
Determine the locations for the keypads. Be sure there is wiring access to
1.
the hub, the speakers, and the local input wall plates (if used).
Install a J-box about 56” to 60” above the fl oor level to mount the keypad.
2.
➜
WARNING:
Do not mount the keypad in the same J-box as
high voltage devices such as a light switch or outlet.
Route Cat-5 cable from the hub location to the keypad J-box. If using the
3.
HI POWER
hub outputs, also route 16-gauge 2-conductor wire from the
hub to the keypad J-box.
Using a Type 110 punch-down tool, connect the keypad’s Cat-5 cable to
4.
one of the
KEYPAD ZONE
terminals on the hub. If using the
HI POWER
hub outputs, connect the 2-conductor wire to one of the
HI POWER
OUTPUT
terminals on the hub.
OBSERVE POLARITY!
Connect the keypad end of the Cat-5 cable to the keypad’s
5.
J1 (HUB)
terminals. If using the
HI POWER
hub outputs, connect the 2-conductor
power wire to the keypad’s
TB1 (26 VDC)
terminals.
OBSERVE
POLARITY!
Optional External IR Target Connection
The keypads support connection to an external IR target. An
external target is useful in some installations where the room
layout requires a remote IR target distant from the keypad.
Mount the external IR target at the desired location.
1.
Route cable for the external IR target from the target’s location to the
2.
keypad J-box.
Connect the cable to the IR target and to the
3
-pin header block supplied
3.
with the keypad.
Attach the
3
-pin header block to the
3
-pin
4.
J3B
header on the keypad.
Note: Red wire position (see Figure 16).
Speaker Connection
One pair of stereo speakers connects to the keypads.
Install the pair of speakers for the keypad’s zone.
1.
Route 16-gauge speaker cable from the speakers to the keypad J-box.
2.
Connect the speaker cable at the speaker end and to the keypad’s left and
3.
right speaker terminals.
OBSERVE POLARITY!
Install the keypad into the J-box and cover it using a Decora
4.
®
type wall plate.
