What is an NFPA 99 requirement for the wiring of the mandatory master alarms?

• A. Wired in parallel
• B. Wired independently to each initiated device
• C. Wired in series
• D. Only one wire for both alarms

Answer: (B)

The requirement for the wiring of mandatory master alarms, as outlined by NFPA 99, specifies that they must be wired independently to each initiated device. This design ensures that the failure of one alarm system does not impact the functioning of another. By allowing each alarm to operate separately, it provides redundancy and reliability in monitoring essential medical gas systems. Each master alarm must be able to accurately report and signal conditions based on its specific source, which is critical in maintaining a safe and effective medical environment. This independent wiring also helps in troubleshooting and maintenance, making it easier to identify and address issues without disrupting the entire alarm system. Overall, such a setup enhances patient safety and hospital operational integrity.
