Which code represents Fire Alarm - Highrise? (reworded)

• A. 3HM
• B. 7
• C. 4
• D. 3S

Answer: (A)

In this coding system, the base number signals the broad category, and the letters add the sub-type to specify the exact situation. For Fire Alarm events, the base is a number that indicates fire/alarms, and the Highrise context is captured by the suffix HM. Put together, 3HM uniquely stands for Fire Alarm - Highrise, giving dispatch and responders precise guidance for a high-rise fire alarm scenario.

The other options don’t carry the Highrise sub-type. A plain number would specify only a general category without the highrise distinction, while other lettered forms point to different sub-types or contexts. So 3HM is the correct, specific label for this high-rise fire alarm situation.
