Microprocessorcontrolled extension amplifiers for voice alarm compact amplifiers with complete monitoring according to VDE 08334 and VDE 08281. 6 switchable and adjustable volume speaker outputs with a total of 240 Watt nominal power output. Audio input for local transmission with choice of outputs over inputs. 8 universally usable inputs and 8 universally usable control outputs; 6 separate inputs for alarm control of the BMZ with switchable monitoring, one with 24volt control (polarity); three separate status outputs with relay contacts for feedback to the BMZ: collective fault signal (changeover contact), emergency activated (changeover contact) and CPU from (normally open). Each line output a switching relay for example external volume control in 3 and 4wire technology. An appropriate additional amplifier can be used as a rescue and announcement enhancer, in the second case, announcements are made without the interruption of background music in durchsagelose areas can be made. The monitoring of the additional amplifier is taken over by the extension amplifier.
