INSTALLATION INSTRUCTIONS

789-44D

ONE ZONE IN-WALL CONNECTING BLOCK

The Model 789-44D is an in-wall version of the 789-44 Connecting

Block and is trimmed with a standard decorator-style cover plate

(not included). It permits connection of Xantech IR Receivers and

Keypads to four single or four dual emitters, with a power supply,

in infrared repeater systems. It can also provide emitter expan-

sion for various Xantech devices, such as the 590, 710, 796-20,

etc. The STATUS terminal provides a convenient tie point for

voltage to drive the STATUS indicator on certain Xantech prod-

ucts, such as the 780-80 IR Receiver (refer to Fig. 3).

SPECIFICATIONS

• Inputs: 1 - Screw-type, 4-terminal plug-in. 1 - IR RCVR, 3.5mm

stereo mini jack. (See Caution Note, Fig. 4).

• Outputs: 4 - Emitter ports (3.5mm mono mini jacks) parallel

driven.

• Contains a 470-Ohm resistor in series with each emitter output.

• Xantech 282, 283, 284 & 286 series Emitters may be used.

• Power: 12 volts DC, 2.1 mm coaxial power jack. Use a 781C-00 or 782-00 Power Supply. Note: A power

supply

is not connected to the 789-44D when it is used as an emitter expander only.

• Dimensions: 1-3/8" W x 1-3/4" D x 4-1/8" H

INSTALLATION

Fig. 2, next page, illustrates a typical installation using the 789-44D in an IR repeater system. A variety of

Xantech IR Receivers and a keypad are shown. When configuring a system, please keep the following

items in mind:

1. More IR Receivers may be wired in parallel, in the same manner as shown, up to a maximum of twelve.

More than twelve is not recommended since IR noise picked up by the many IR receivers may cause

erratic operation and reduce remote control range.

Note: This restriction does not apply to Xantech Smart Pad keypads. These may be added virtually

without limit, provided power supply requirements are taken into consideration. See item 3.

2. Be sure to connect the +12V, Output and Gnd of each IR Receiver and keypad to the respective +12V,

IR IN, GND and STATUS (where applicable) of the connecting block as shown.

3. Xantech Smart Pads may be used by themselves or together with IR receivers as shown. When you

do this however, the higher current requirements of the keypads must be taken into consideration as

follows:

a) Each 730-00 keypad draws 70 mA. A Smartpad

or Smartpad

draws 85 mA.

b) Each IR receiver draws 10 to 20 mA (check specs. on actual model).

c) The max. current for proper operation from the 781C-00 Power Supply is 120 mA.

d) The max. current from the 782-00 Power Supply is 1000 mA.

e) When using combinations of keypads and receivers, do not exceed the max. current of the power

supplies as noted above.
