Strange request from the customer,

I have a 4 bank Tac50-04 controllers, 19 landings. The 9th floor is high security, not sure what they do there but it’s 2 guys in a hallway with guns and body armor. A front desk with a metal detector. They want the hall lanterns to “gong!” Go off when somebody has arrived on the 9th floor. General the lantern will only go off when a hall call is latched not car calls.

My lanterns use a 6300WG board in the wall and is wired cat5 to my HN cards in the raceway. There’s an HN card on every floor serving 1 bank. (2 units) and more HN cards serve the other.

Is there anyway to change the programming for this? Or a particular jumper configuration?
