How often should a household fire alarm send a communication signal to the monitoring station?

• A. Weekly
• B. Monthly
• C. Daily
• D. Annually

Answer: (B)

Regular verification of the communication path with the monitoring station is essential for a monitored household fire alarm. The panel sends a supervisory (heartbeat) signal to the monitoring station to confirm it can reach the central station and that the monitoring path—whether via phone line, cellular, or IP—is working. Monthly is used here because it provides a consistent check of the link without overloading the system with too many transmissions, while still catching path problems in a timely way. Weekly or daily transmissions would be unnecessarily frequent and could add extra costs or burden, and annual transmissions would leave long gaps during which a faulty path could go undetected.
