ƒ VTR73xxA Occupancy function remote inputs. All wiring for those remote inputs is located at the wall VTR73xxA
Terminal Equipment Controller.
o BI1 can be configured for:
ƒ None = no functions associated
ƒ Motion NO = for a remote normally opened contact PIR motion sensor
ƒ Motion NC = for a remote normally closed contact PIR motion sensor
ƒ Rem NSB = for usage with a remote on-off contact device for the occupancy function. A typical application
is a room tenant card holder, which force the occupancy if the card is inserted in the holder.
ƒ Window = A local and / or networked window opened alarm. The system heating and cooling actions are
also locked out.
o BI2 can be configured for:
ƒ None = no functions associated
ƒ DoorDry = for usage of a PIR and entrance door switch for lodging occupancy routine
ƒ All communication wires ( if needed ) are located at the VTR73xxA Terminal Equipment Controller
