INSTALLATION INSTRUCTIONS

791-44

AMPLIFIED CONNECTING BLOCK

The Model 791-44 is an Amplified Connecting Block that permits up to 10 single or 10 dual emitters (or any combination thereof) to be driven directly at high or low power levels. Up to 100 emitter ports may be driven using 790-00 passive connecting blocks 'daisy chained' from the HIGH IR OUT port. The 791-44 interfaces all Xantech IR Receivers and Keypads to the emitters along with a power supply in an infrared repeater system. It can also serve to provide emitter expansion at the output port of other Xantech devices, such as the 590 Programmable Controller, the 710 Fone Link™ and the 796 Zone Expander. A floating terminal is provided for "STATUS" line connections.

SPECIFICATIONS

4-screw plug-in terminal for +12VDC, GND, STATUS, & IR IN.

Quick connect "IR RCVR" input (3.5mm mini stereo jack).

Red talk-back LED flashes with IR input signal.

Ten EMITTER output ports, parallel driven (3.5mm mini mono jacks).

HIGH IR OUT port for emitter expansion (3.5mm mini mono jack). See Fig. 5.

Use of included jumpers connect either a 100 or a 470-Ohm resistor in series with each emitter jack for high or low power operation.

282/283/284/286 series of Emitters may be used in any combination.

Power requirements: 12 volts DC. Uses 781RG or 782-00 Power Supplies (see item 3 below).

2.1 mm coaxial power jack.

Dimensions: 6" W x 2-1/4" D x 15/16" H

INSTALLATION

Fig. 2, next page, illustrates a typical installation of a 791-44 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 because 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 Pads. 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 +12VDC, IR IN and GND of the connecting block as shown.

3.Power Supply Requirements. You may combine many Xantech keypads, IR receivers, controllers and emitters in a system. Having sufficient power supply voltage and current available is critical for proper operation. Be sure to take the following factors into consideration:

a)The maximum current for proper operation from a 781RG Power Supply is 120 mA (milliamps).

b)The maximum current from a 782-00 Power Supply is 1000 mA.

c)Most IR receivers draw 2 mA without signal and 10 mA with signal (check specs. on actual model).

d)Each 730 Smart Pad draws 7 mA without signal and 65 mA with signal.

e)Each Smart Pad2 or 3 draws 85 mA with or without signal.

f)Each emitter draws 3 mA in low power mode and 12 mA in high power mode.

g)Add 10 mA for each 794 or 797 Interface module used, if they are powered from the 791-44.

h)When using combinations of these devices, add up the currents as shown in the following example. Then choose the power supply or supplies. Do not exceed their maximum current capabilities as noted above!

For example, the power supply needed for the system shown in Fig. 2 is arrived at as follows:

a)The no signal current for the five IR receivers is 5 x 2 = 10 mA.

b)Assuming a Smart Pad2 or 3 keypad, the with or without signal current is = 85 mA.

Note: Since only one IR source can operate at a time, the lower current IR receivers (and 730 keypads if used) do not need to have their "with signal" currents included.
