If speakers are used in fire alarm systems, what is a key requirement?

In fire alarm systems, if speakers are utilized, one of the key requirements is that speakers must be monitored for integrity. Monitoring ensures that the speakers are functioning correctly and are able to deliver the necessary audible warnings during an emergency. Integrity monitoring confirms that the connection to the speakers is intact and that they are operable, which is essential for the effectiveness of the alarm system in alerting occupants to potential dangers.

By ensuring that speakers are monitored, the fire alarm system can reliably communicate life-safety messages, which can be critical during an emergency situation. This requirement helps to maintain the overall reliability and functionality of the fire alarm system, providing peace of mind that the intended alert will be successfully delivered to occupants when needed.

While there are other considerations for speakers in a fire alarm system, such as maintenance and operational efficiency, the focus on monitoring integrity is a fundamental aspect of ensuring that the system will perform effectively in real-life emergencies.
