We have a SR01 that we intend to pair with an S539 Intercom. The SR01 will be located at a gate closure and I found out the power at the gate closure is 24v (actually more like 27v). I was wondering if the SR01 would still work if being powered with the 24vdc source? I don't think I'll be using it to power a door lock as the gate assembly will be handling that.
