During a complete test of a monitored system, which statement best describes verification of signals?

• A. Test only a subset of devices and verify with central station
• B. Verify with central station that all signals were correctly received
• C. Ignore central station responses while testing
• D. Record test results without verifying signal receipt at the central station

Answer: (C)

Verifying signals during a complete test means confirming end-to-end delivery from every monitored device to the central monitoring station and ensuring the station logs or acknowledges each signal. This checks that the communication path from sensor to station is functioning, that the correct zones and event types are reported, and that the central station can receive and process alarms. If you skip this verification or ignore the station’s responses, you might miss transmission issues, a downed line, or a misconfigured device, making the test incomplete. The best practice is to verify with the central station that all signals were correctly received and to document that confirmation for every device tested.
