Nurse Call System Calculator

Patient rooms feeds four device categories at once -- Bedside stations and Pillow speakers (per bed), plus Bathroom pull cords and Corridor dome lights (per room) -- so it touches the largest share of device categories in Total devices. In practice, though, a one-room change and a one-nursing-unit change move Total devices by nearly the same amount at this calculator's defaults (a marginal patient room adds about 7 devices at 2 beds/room; a marginal nursing unit adds about 6) -- it's a near-tie, close enough that either input can end up dominating depending on your specific counts, not a clear-cut "patient rooms always matter more." Staff restrooms move the total by less per unit, since they only drive a single device category (staff toilet stations).

Both. Facility type changes quantities through the assumed average wire run length (150 ft acute care, 120 ft long-term care, 80 ft clinic), but it also switches entire device categories on or off: Pillow speakers apply to acute care and long-term care but not clinics, and Code blue stations apply only to acute care hospitals (facility type 1), reading zero for long-term care and clinic facility types.

Both System processors and Ups Units are calculated as Call stations divided by 64, rounded up to the next whole processor -- a typical processor capacity for this class of system. Since Ups Units always equals System processors in this calculator, every processor gets its own backup unit rather than a shared or redundant UPS scheme.

No -- Wire spools (1000 ft) is Call stations multiplied by a flat average run length per facility type (150/120/80 ft), then divided into 1,000 ft spools and rounded up. It is a budgetary planning figure for a typical single-floor layout, not a routed cable takeoff that accounts for vertical risers, above-ceiling obstructions, or a specific floor plan.
