What is the required condition for connecting an access control system to a fire alarm system?

The correct condition for connecting an access control system to a fire alarm system is that it must be supervised. Supervision means that the access control system is monitored for malfunctions or issues that could affect its performance, especially in emergencies. This requirement is critical to ensure that if there is a fire, the system will function as intended, allowing for safe egress from the building and ensuring that doors controlled by the access system can be opened in the event of an emergency.

When an access control system is integrated with a fire alarm system, it needs to respond appropriately to signals from the fire alarm, such as unlocking doors automatically during a fire alarm event. Supervision helps to maintain the integrity and reliability of the system, ensuring that any faults or changes are detected and addressed quickly.

Other conditions, such as being installed in a locked enclosure or by a licensed technician, while important for security and compliance, do not specifically address the safety and functionality requirements mandated for integration with fire alarm systems. Similarly, using wireless technology is not a requirement for safety or functionality in this context.
