Emergency voice/alarm communications systems are critical for ensuring that occupants can receive timely and accurate information during emergencies. These systems must be equipped with a reliable power source to remain operational even during power outages. The National Fire Protection Association (NFPA) standards specify that such systems should have a minimum standby power capability of 24 hours. This period allows sufficient time for emergency personnel to respond and complete their operations effectively, especially in prolonged emergencies.

Having at least 24 hours of standby power ensures that the system can continuously provide alerts and voice instructions, which are vital for guiding occupants to safety in the event of an evacuation or if the situation evolves. This requirement reflects a balance between practical operational needs and the realities of emergency response scenarios, ensuring adequacy while considering resource limitations. Systems with standby power for less than this specified duration would not be sufficiently reliable during extended emergencies.
