Reference Configurations
Six designs by site type, each with the parameters it was sized on and the equipment list that follows from them: a small office, a 120-room hotel, a 50-bed clinic, a 70-bed nursing home, a 300-extension office and a campus public address system. Every list is built from the published capacity and product data, and each one is confirmed against your own counts on the quotation.
- Small office
- 120-room hotel
- 50-bed clinic
- 70-bed nursing home
- Multi-floor office, 300 extensions
- Campus PA and emergency broadcast

Compare the six designs
The six are not sized on the same dimension: a hotel is worked out from guest rooms, a clinic from beds and call points, a campus broadcast from buildings and zones. The second column shows the dimension each design was actually sized on, so you can place your own site against it.
