Which of the following should be connected to the fire alarm system in order to help prevent the spread of a fire in a server room without data loss to assist in an FM-200 deployment?

A water-based sprinkler system would cause significant data loss and equipment damage in a server room, making it incompatible with an FM-200 deployment.

Cutting electrical power is a separate safety action but does not prevent the agent from being vented out of the space, which is the specific problem FM-200 integration addresses.

FM-200 is a clean-agent gaseous suppression system that works by achieving a specific concentration of gas within a sealed space to suppress fire. If the HVAC system continues to run, it will exhaust the agent before the required concentration is reached, making suppression ineffective. Integrating the HVAC with the fire alarm ensures the system shuts off automatically upon alarm, maintaining the agent concentration needed for suppression.

Video surveillance has no ability to control airflow or affect the concentration of suppression agents in the room.
