Installation Page 7
Chapter 2: Installation
1. Control panel Combus connection
NOTE: If you are using the RTX3 as a stand-alone device, connect an
external 12Vdc power supply to the RED and BLK terminals. Battery backup
is recommended.
2. If the current draw exceeds 150mA on PGM1 or PGM2, use a relay.
Connect the RTX3’s RED connector to the relay’s RED connector, and the
PGM connector (PGM1 or PGM2) to the relay’s BLK connector.
3. Connect PGM3 and PGM4 to external power supplies if you need additional
power. A PS-817 is recommended. Connect the PGM’s N/O connector to
the external power supply’s “+” connection. Connect the power supply’s “-”
connector to the device’s “-” connector. Connect the PGM’s COM connector
to the device’s “+” connector.
NOTE: Write down the serial number of all wireless modules to be used with
the RTX3. If this installation replaces another RTX3, make sure the
programming can be transferred.
System Reset
The system reset feature only functions during the first 30 seconds after RTX3
power up. In order to reset the system, press and hold the Programming button
for 5 seconds, the BUS RX LED flashes. Release the button and press it again
while the LED flashes to reset the module to its default values.

Chapter 3: Programming
This chapter provides programming instructions for Imperia l, Spectra SP
Series, EVO, Esprit, and stand alone installations.
Programming for Imperial
When connected to an Imperial panel, all RTX3 settings are programmed using
BabyWare. For more detailed instructions on using BabyWare and
programming remotes, refer to the Imperial System Guide.
