I ran into a problem which may be my own doing. had a 912 relay about 75 feet from the panel and used an output to trigger it. The wiring is standard alarm wire so I am assuming I had a voltage drop and increase in current. I am trying not to have to snake new wire so I am thinking of putting a 912 relay by the M1 panel connected to one of the outputs say #12 and from that relay connect a 12v power supply to trigger the 924 relay 75' away. That way I will not be taxing the panel due to voltage drop. The 924 relay 75' away is powering a 120v outlet.
