How often should the digital alarm communicator transmitter (DACT) be tested in accordance with the manufacturer's published instructions for correct operation?

• A. Monthly
• B. Biennially
• C. Annually
• D. Every five years

Answer: (C)

Maintaining the reliability of the path from the fire alarm system to the central monitoring station is the key idea. The DACT’s role is to transmit alarms to that central station, so its operation must be verified on a defined maintenance schedule. Follow the manufacturer’s published instructions for correct operation, which for many DACTs means performing a functional test at least once a year. An annual test confirms that the dialing/communication path is still viable, the central station correctly receives the signal, and any related supervision, battery backup, and line status are functioning. This interval balances practical maintenance with ensuring reliable remote reporting. If the manufacturer specifies a different interval, that instruction takes precedence. But when the manual indicates annual testing, that is the best-supported answer and aligns with standard maintenance practices.
