I would like to be able to trigger the hold open for the drive gate. The operator runs off a battery. The connections terminals have connections for +12vdc. -12vds, “open”, “hold open”, “close”, “hold close”, and more. I think I need a 2 relay dry contact z wave that can run off of DC power. I am not sure if the FortrezZ Z-WavePlus MiMO2+ Interface Module is the correct choice. I think the “hold open” could be triggered until the gate is open using time as the estimate for how long to keep the relay triggered. There may also be a connection that can be made to the open limit to stop the trigger. Alternatively the “open” could be triggered just a few seconds. Then use time or the open limit to wait to trigger the “hold open” for a few seconds. When it is time to close the gate the “open” could be triggered a few seconds to start the boards close timer which will then close the gate. This way I would not need three dry contact relays. Has anyone done this and can provide ideas?
