Smartrise A58 lobby fire key

Hey guys , me again with another Smartrise problem , 2 months ago the car had no phase 1 recall. Replaced the board in Lobby hall station for fire, now every week I get the A58 lobby fire key on the controller. Manager says it goes on by itself. What do ya think ? Change the board out again ? Thanks

Generally the boards fail to a loss of communication, odds are its a faulty switch.
