When replacing a valve tamper for a dry system, what signal would you expect from the control panel?

• A. Alarm
• B. Supervisory
• C. Trouble
• D. No signal

Answer: (B)

A supervisory signal is produced. Valve tamper and similar monitored devices are designed to inform the control panel when their status changes, such as during maintenance or replacement. Replacing the tamper on a dry-system valve isn’t an active alarm (no water flow or heat event) and isn’t a fault (not a malfunction), but it is a change in the status of a monitored component. The panel therefore flags a supervisory condition to alert personnel that the valve tamper has been accessed or is being replaced and should be reinspected and restored to normal.
