Final answer:
The emergency communication system does not have to be audible throughout the facility.
Step-by-step explanation:
The statement is false. The emergency communication system does not have to be audible throughout the facility. It can be designed to send alerts only to specific areas or individuals.
For example, in a large building with multiple floors, the emergency communication system can be set up to transmit messages through speakers in common areas like lobbies and hallways, without the need for sound to reach every corner of the facility. This allows for more targeted communication and reduces the risk of confusion or unnecessary panic.
Therefore, the emergency communication system does not have to be audible throughout the facility.
