Before going into the software section of the relay board setup let’s confirm that all hardware is installed properly.
Below is a basic checklist that will aid you. Please check off each item as it is completed:
- Relay board is installed and powered with a 12VDC power supply. The red power OK LED should be lit.
- Relay board surge board is properly wired to the UltraConverter and you are seeing alternating red and green RS-485 LEDs.
- Relay board surge board’s EARTH GROUND is properly grounded within 6 feet of the board.
- Each siren is installed and properly wired to the relay board relay designated in the software.
If you are using the relay board for auxiliary devices, such as elevator control or lighting, then you should now have the devices wired per the device manufacturer’s recommendations.
