Which code is used for Fire Alarm - Multi Family Dwelling?

• A. 3S
• B. 3M
• C. 3R
• D. 3MC

Answer: (B)

In this coding system, the first part marks the general category of the call (fire alarm), and the letter specifies the type of structure. For fire alarms, the letter identifies the dwelling type. The letter M stands for Multi Family Dwelling, so the code used for a fire alarm in a multi-family building is 3M. This distinguishes it from other dwelling types (like single family, which would use a different letter) and from other fire alarm scenarios. The result is a precise, rapid signal that helps responders anticipate occupancy and layout challenges, coordinate resources, and tailor the response accordingly.
