What is the primary purpose of a central alarm/release interface in a building's fire alarm system?

• A. To monitor battery conditions and report to maintenance.
• B. To coordinate alarm signaling with building systems such as elevator recall and door locking or hold-open devices.
• C. To log alarm events for post-incident analysis.
• D. To control HVAC during alarm.

Answer: (B)

When a fire alarm activates, the system needs to coordinate what happens beyond just sounding a siren. The central alarm/release interface is the link that makes those other life-safety actions happen automatically. It sends the alarm signal to building systems like elevators and door controls so elevators can recall to a safe floor and doors with hold-open or access-control devices respond appropriately (locking or releasing as needed) to control movement and containment.

This coordination is essential for safe evacuation and smoke containment: doors close to compartmentalize areas, elevators aren’t used in unsafe conditions, and people have a clearer path to exits. Other options aren’t the primary function here—monitoring battery conditions deals with maintenance, logging events is for records after the fact, and HVAC control is a related but separate action that isn’t the core purpose of this interface.
