What is the minimum interval for automatic test transmissions by a digital alarm communicator transmitter?

• A. 12 hours
• B. 24 hours
• C. 36 hours
• D. 48 hours

Answer: (C)

Automatic test transmissions from a digital alarm communicator transmitter are supervisory checks that verify the communication path to the central monitoring station and ensure the device and its power and line circuits are functioning properly. This keeps the monitoring path from silently failing without notice. The minimum interval for these automatic tests is 36 hours. This cadence provides regular verification of the signaling path while avoiding excessive signaling traffic. If the interval were shorter, you’d be generating too many test transmissions and could burden the monitoring service and maintenance workflow. If it were longer, a fault in the DACT, the power supply, or the communication line might go undetected for too long, leaving the system vulnerable. So 36 hours strikes a balance between timely detection of issues and practical signaling load.
