I just finished installing a lighting controller. The lighting controller is not from an Elk partner so it does not directly communicate with the M1. I planned to use relay outputs to simulate buttons to activate the individual lights. The problem is the inputs to the Elk from the lighting controller. The lighting controller has LED outputs that I had planned to use as Inputs to the Elk so it knows what lights are on or off. None of my buttons are illuminate4d so I do not have to parrallel the Elk Input with an LED.
Problem: The LED outputs from the lighting controller are -24VDC. That isn't a typo. Negative Volts DC. For an LED all you would have to do is reverse the cathode and anode. I can't reverse the inputs to the Elk Input Expander because two inputs share one common.
1. Can the ELK-M1XIN be programmed to operate at a negative voltage using the ELK-RP?
2. Can the Input Expander safely accept 24VDC? If not I do know how to step it down to the 12VDC that the Elk normally operates on.
The hard way to work around this involves 16 relays triggered from the lighting controller LED signals but that involves a lot more wiring and introduces more points of failure.
Thanks in advance for your assistance.
