How often should a digital alarm radio receiver (DARR) be tested?

• A. Annually
• B. Monthly
• C. Biannually
• D. Quarterly

Answer: (B)

Regularly checking the DARR on a monthly basis keeps the life-safety communication link reliable. A digital alarm radio receiver depends on a radio path, power sources, and the monitoring station receiving signals. These parts can degrade or fail—batteries discharge, antennas get damaged, or the transmitter momentarily malfunctions—so monthly tests quickly catch issues before a real alarm occurs. Consistent monthly testing also helps maintain accurate maintenance logs and aligns with typical expectations for monitoring equipment, ensuring alarms are transmitted and acknowledged when needed. Testing less often increases the risk that a failure goes unnoticed for weeks or months, potentially delaying notification during an actual incident.
