Bosch Plena - Fault Indicators

Fault indicators
The voice alarm controller, voice alarm router and remote controls have two types of fault
indicators: System fault indicators and loudspeaker line fault indicators (see Supervision, page
78). The system fault indicators provide information about failing system functions that are
supervised. If a system fault is persistent, contact your Bosch representative.

The loudspeaker line indicators provide information about failing loudspeaker lines. They
indicate short-circuit and impedance supervision faults (see section Line supervision, page 80).
If a loudspeaker line indicator lights, check the wiring of the indicated loudspeaker line and try
to solve the fault. If it not possible to determine the fault, contact your Bosch representative.
