Which code indicates a frequency change?

• A. Code 5
• B. Code 2
• C. Code 9
• D. Code 10

Answer: (C)

In alarm monitoring, each code is tied to a specific event type, so operators know exactly what action to take. A frequency change means the RF channel or frequency used by the transmitter/receiver has been altered, which can impact link quality and coverage. The code that flags this particular event is the one designated to indicate a frequency change, so when you see it, you know to verify and implement the change in the RF setup. Handling this involves confirming the change is authorized, checking the frequency plan and logs, updating equipment settings as needed, and then re-testing to ensure the link remains solid. The other codes correspond to different events (like power status, maintenance, or system checks) and do not signal a frequency change, which is why they wouldn’t prompt the same response.
