Under the MasterSpec®, fire alarm specifications are found in Division?

• A. Division 16
• B. Division 32
• C. Division 21
• D. Division 28

Answer: (D)

In MasterSpec, fire alarm specifications sit in Division 28, the Electrical division. This is because fire alarm systems are electrical control and signaling systems, involving power supplies, wiring, control panels, and devices like smoke detectors and audible alarms. They’re coordinated with electrical distribution and electrical standards, so they belong with other electrical work.

Division 21 covers fire protection in the sense of fire suppression (sprinklers, stands, extinguishing systems), not the alarm signaling. Division 32 is site work and exterior improvements, not building interior systems, and Division 16 is mechanical. So Division 28 is the most appropriate home for the fire alarm specifications.
