## Call Priority and Escalation {toc}
−### Escalation logic ensures that an unanswered call does not remain silent; the number of priority tiers and the timeout before re-annunciation are facility-configurable and must be standardized across the facility before design is complete. {note}
+### Escalation logic ensures that an unanswered call does not remain silent; the number of priority tiers and the timeout before re-annunciation are facility-configurable and must be standardized across the facility before design is complete.
### The system shall support at minimum three call priority tiers: standard call, staff-assist/urgent, and emergency.

## Corridor Dome Lights {toc}
−### Corridor dome lights give staff an immediate, glance-able indication of where a call originates and at what priority; their color conventions must be uniform facility-wide, because differing conventions between nursing units on one server is a documented source of staff confusion and post-occupancy change orders. {note}

### A corridor dome light shall be provided at the corridor side of each patient room door and at the entrance to each multi-bed bay.

## Battery Backup {toc}
−### Battery backup duration must be coordinated with the essential electrical system transfer time; where the automatic transfer switch restores power in seconds, a short bridging duration suffices, but facilities with long transfer times or a history of extended outages require extended backup, and some authorities require longer durations for Category 1 facilities. {note}

### The central controller or server shall be supported by battery backup providing a minimum of 15 minutes of operation in accordance with ANSI/UL 1069.

## RTLS and Bed-Status {toc}
−### Smart-bed integration delivers bed-exit, rail-position, and head-of-bed-angle data to the NCS, but the communication protocol and data-point mapping differ by bed manufacturer and must be confirmed before shop drawings are submitted; leaving this scope unresolved between the NCS contractor and the bed vendor is a recurring coordination gap. {note}

### Where bed-status integration is included, the bed communication protocol and the data-point map shall be confirmed in writing with the hospital bed manufacturer before shop drawings are submitted.
