Which element is represented by three values: Site Number, Priority, & Class in the lockdown context?

• A. Priority A
• B. Lockdown Response Code (LRC)
• C. LRC Site Number
• D. LRC Priority

Answer: (B)

In lockdown procedures, a single code carries multiple pieces of information so responders can act consistently across sites. That code is the Lockdown Response Code. It’s designed to encode three pieces: the Site Number (which location is involved), the Priority (how urgent the situation is), and the Class (the level or type of response required). Seeing this code tells you where the event is, how severe it is, and what kind of actions to initiate, all in one compact identifier.

A plain priority value only communicates urgency, not location or the classification of response. A site number alone identifies the location but omits urgency and the response type. Terms that imply only two components don’t capture the full three-value construct represented by the Lockdown Response Code.
