How often should two-way communication systems be tested according to NFPA 72?

The National Fire Protection Association (NFPA) 72 sets the standards for fire alarm systems, which include specific requirements for testing and maintenance. For two-way communication systems, NFPA 72 mandates that these systems should be tested every six months. This regular testing is essential to ensure that the communication system is fully operational and effective for emergency situations, enabling clear communication between building occupants and first responders.

Implementing a six-month testing schedule helps identify any issues that may arise over time, such as equipment failures or communication breakdowns, thereby maintaining the safety and effectiveness of the system. Adhering to these standards ensures compliance with regulatory requirements and promotes the safety of individuals relying on these systems during emergency situations.
