I think never saw that controller, but if it works like LCB2 mainboard from MCS and MRL, there is 2 dip sitches. One for cut the power for door operation (to not open) and the other one for cutting the hall calls and works like you said. Cheers

If it is slowing down for a hall call that means HST is coming in. If the doors are not opening, XDO and or CPR is not coming in, look in those circuits and you should find an HST contact in one of them that opens the doors.
