NFPA-99 Practice Exam

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

1. Alarms shall be sent to the area alarm panel in the emergency room

2. Common conductors

3. Wired independently to the initiating device for each signal

4. Without any splices

The correct answer is: Wired independently to the initiating device for each signal

The NFPA 99 requirement for the wiring of mandatory master alarms emphasizes that the wiring must be done in a manner that ensures reliability and clarity in alarm signals. The specification that they must be wired independently to the initiating device for each signal is crucial because it allows for individual identification of alarm conditions, which is essential for effective response and management of alarms in healthcare facilities. Wiring the alarms in this manner reduces the risk of confusion and ensures that each alarm can be distinctly recognized without interference from other systems. This independence minimizes the possibility of signal crossover and allows for quicker troubleshooting and maintenance, ensuring the safety of patient care environments. The other options may not fulfill these specific needs for clarity and operational integrity in alarm systems, as they might not provide the required level of separation and identification for alarm signals.
