How do I install the wires for an iNX/iDX to a Carmanah RRFB?
Terminal Block Connections:
PWR (+) & GND (-): The iNX needs 10-24 VDC between PWR (power) and GND (ground) in order to power the button. This voltage must be present at all times for proper operation.
BUTTON (+/-): The iNX accepts 7-32 VDC across button terminals. When the PBS is powered and the physical button is pressed, the voltage will drop to ~0VDC. This is a contact closure connection that signals the RRFB controller to activate the warning lights.
There is no polarity requirement, the terminals accept either orientation.
LIGHTS (+/-): The iNX needs a voltage signal from the RRFB in order to play the warning message. The iNX accepts 7-32 VDC to the LIGHTS terminal. The voice message will not play without the button detecting this voltage. There should be no voltage (0 VDC) when the RRFB warning lights are inactive (not flashing).
There is no polarity requirement, the terminals accept either orientation.
