The Plena Voice Alarm Controller is the heart of the voice alarm system. It is the basis of the Plena Voice Alarm
System, and has all the essential functionality for compliance with the EN 60849 and 54-16 standards, including full system supervision, loudspeaker line impedance supervision, a supervised emergency microphone on the front panel and a supervised message manager.
A built-in 240 W amplifier provides the power for the emergency call channel and BGM. Additional Plena
Amplifiers can be added to provide two-channel operation. All amplifiers are supervised. The audio output uses standard analogue audio 100 V line switching for full compatibility with the Plena family of public address equipment and Bosch EVAC-compliant loudspeakers. The system is configured using DIP switches for basic functionality and a PC for more advanced functions.
