Add-on devices to a wireless security system cannot be supervised by their nature. Which of the following is true?

• A. TRUE
• B. FALSE
• C. Not determinable
• D. Only supervised if connected to main panel

Answer: (B)

Supervision means the panel regularly checks in with each device to verify it’s online and functioning. In wireless systems, many devices send periodic status updates or heartbeats so the panel can detect a lost connection or tampering. Add-on wireless devices, such as extra sensors or remote controls, can be designed to be supervised, which means they will actively communicate with the main panel and report any issues.

The statement claiming add-ons cannot be supervised by their nature is not correct. Whether a device is supervised depends on its design and configuration, not on being an add-on. Some add-ons are supervised, some are not, but supervision is certainly possible for add-on wireless devices.
