How often should digital alarm communicator transmitters (DACT) using call forwarding to DACR be tested?

The correct frequency for testing digital alarm communicator transmitters (DACT) using call forwarding to Digital Alarm Communicator Receivers (DACR) is every 4 hours. This testing interval is established to ensure that the communication link between the DACT and DACR is functioning properly, which is crucial for the reliability of fire alarm systems. Regular testing helps identify any potential issues in the signal transmission, such as disrupted communications or system malfunctions, that could hinder the response to an emergency situation.

By adhering to this 4-hour testing requirement, fire safety professionals can ensure that any failures in the communication process are detected promptly, thereby maintaining the integrity and effectiveness of the fire alarm system in alerting necessary personnel and emergency services when an event occurs. Such periodic testing is a part of best practices in fire alarm system maintenance and contributes significantly to overall safety and compliance with relevant codes and standards.
