The PRAESENSA VACIE, consisting of PRAESENSA devices and associated support devices and
optional batteries, is typically housed in one or more free‑standing or wall‑mounted rack
cabinets. These cabinets can be at one central location or decentralized, servicing a larger
area. PRAESENSA end‑of‑line devices, used for loudspeaker line supervision are mounted at
appropriate locations, in accordance with the directions provided in this manual.
