Supervised wireless devices means which of the following is monitored?

• A. Battery
• B. Tamper or cover on transmitter
• C. Device status
• D. All of the above

Answer: (D)

Supervised wireless devices are checked by the panel to ensure ongoing reliability. The panel regularly receives updates about several aspects of each device, not just whether it can communicate.

Battery status is monitored so a low battery can trigger a warning before the device dies and leaves the zone unprotected. Tamper or cover status is watched to detect any attempt to open or remove the device, which could compromise security. Device status covers the overall health and online condition of the device—whether it’s communicating, its last report, and its signal quality.

Because supervision encompasses all of these elements, a supervised device provides comprehensive monitoring. If any of these aspects fails or goes out of range, a supervision alert or trouble can be generated, ensuring prompt attention. That’s why all of the above is the correct interpretation.
