Fire alarm panel trouble or supervisory signal: what it means

Fire alarm panel shows a trouble or supervisory signal

Address promptly

What is likely happening

A trouble signal means the system has detected a fault in itself, such as a wiring problem, a failed battery, or a disconnected device. A supervisory signal often means a monitored valve or other component is off-normal. Either way, part of the system may not work in a fire.

What you can safely check

What an inspector will look at

Does this affect compliance?

Fire alarm systems must be kept in service and tested on a set schedule; an impaired system may require notifying the fire department.

When it becomes urgent

Urgent until the fault is found; ask your local fire authority whether a fire watch is needed.
