Plena Voice Alarm System | Installation and User Instructions | Operation
The loudspeaker line indicators provide information
about failing loudspeaker lines. They indicate short-
circuit (see section 18.11.3) and impedance supervision
(see section 18.11.2) faults. 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 dealer.
