Does anyone know how the panel picks up a sounder fault. From what i've read it has a potential divider arrangement , as the resistance changes on sounder circuit this is then picked up by the panel. The normal range is 2 to 6 mA at 24v. I get that to ideal resistance of 6k. black phds america

First start with a variable voltage power supply of moderate current capability with the voltage turned down and ramp it up until you get a satisfying click. Then calculate the current and design your circuit accordingly. This isn't likely to be too critical - most small transistors or FETs can probably do it. black pheasant hawaii
