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

+12VDCIR 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 Pad

2 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 Pad

2 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.

c) The current for one 794 Interface module

 = 10 mA.

d) The current for six emitters is 6 x 3 = 18 mA (in the low power mode. Also the 286 dual emitters

count as only one, since they are in series).
