9.2.2 Zone Errors
Zone errors are the errors which generate the switch off of one or more zones. When a zone error is
detected, the involved zones are switched off, a beep sounds (only if one or more zones are active) and the
display corresponding to these zones show a
‘ F ’ letter and the error code alternately.
While in error status the keys of the corresponding zones are not operative. All errors are recoverable. That
is, when the cause of the error disappears, the corresponding displays are deactivated and the zones return
to normal operation.
