Everything was working since install months ago but this week the 6160 panel shows zones 3 and 5 have an open sensor while window and door are closed. konnected shows the sensors closed when both open or closed. Disconnected those zones from the add on board and panel started showing correctly. When the add on board zones are reconnected, the error returns. Tried a meter and there’s no current for the zone when the add on board is connected. Seems like the zones went bad on the add on board. Could this be a sensitivity thing?
Thanks
