How to interpret the CHECK DEVICE on a D7212B/D9112B Panel.

At least one point in the panel is following a point index with 'Buzz on Fault' set to YES.

When set to Yes, the command center will sound the trouble tone for any fault condition and CHECK DEVICE will display until the point is restored to normal.

If Buzz on Fault is not desired, either modify the Buzz on Fault setting to No or use a different point index to the point with the parameter set to No.
