If a digital alarm communicator transmitter calls a number that is forwarded to the receiver, how often must the integrity of the call forwarding be verified?

• A. 2 hrs
• B. 4 hrs
• C. 6 hrs
• D. 8 hrs

Answer: (B)

When a digital alarm communicator transmitter uses a number that forwards to the monitoring receiver, the path the signal travels can change or fail without immediate notice. To ensure alarms actually reach the receiver, the forwarding arrangement needs regular checks. Verifying the integrity of that call forwarding every 4 hours provides a timely check that the forwarding path is still active and correctly routing signals to the monitor. This interval is chosen to balance reliability with practicality, catching issues like number forwarding failures or changes in the route before an alarm event goes unmonitored. So, the required frequency is every 4 hours.
