What must a building have in order to comply with NYC regulations concerning the One-Way Voice Communication System?

For a building to comply with NYC regulations regarding the One-Way Voice Communication System, having proper signage indicating the presence of the system is essential. This signage is crucial for ensuring that occupants and emergency personnel are aware of the system's existence and functionality. Clearly marked signage helps to facilitate quick and effective communication during emergencies, allowing individuals to utilize the system without confusion. It serves as a guide to direct people to use the system when necessary, particularly in high-stress situations where effective communication can enhance safety.

Additionally, while other elements such as backup power supplies or designated operators may be desirable for the overall safety and reliability of emergency systems, the presence of identifiable signage specifically addresses compliance with regulations aimed at informing building occupants about emergency procedures.
