Fault indicators

The voice alarm controller, voice alarm router and remote controls have two types of fault
indicators: system fault indicators (see Figure 7.21) and loudspeaker line fault indicators (see
Figure 7.22). The system fault indicators provide information about failing system functions
that are supervised (see Table 7.2). 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 6.2.10 ). 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.
