Where may the disconnect switch be located according to requirements?

• A. Inside a lockable fire alarm control panel
• B. Inside a lockable enclosure
• C. Require a key for activation of the switch
• D. Any of the above

Answer: (D)

The key idea is that the disconnect switch must be accessible to authorized personnel and protected from tampering, but its exact location can vary as long as those security and access requirements are met. Placing it inside a lockable fire alarm control panel integrates control with the system and allows a lock to prevent unauthorized operation. Locating it inside a lockable enclosure provides external protection while keeping access controlled. Requiring a key to activate the switch ensures that only trained individuals can operate it. Since NFPA 2001 allows these different configurations, any of the above setups satisfy the requirements, so “any of the above” is correct.
