Phase I recall is a term used in relation to which equipment?

• A. Elevators
• B. Sprinklers
• C. Fire pumps
• D. Kitchen hoods

Answer: (A)

Phase I recall is an elevator system function. When the building’s fire alarm or detection system is triggered, Phase I automatically recalls passenger elevators to a safe floor (typically the lobby) and disables normal elevator operation. This keeps people from using elevators during a fire, reducing the risk of entrapment or exposure to smoke and heat, and it provides a clear egress path on accessible floors while firefighters prepare to take control. The other equipment listed—sprinklers, fire pumps, and kitchen hoods—do not use this recall terminology, so Phase I recall specifically relates to elevators.
