Heart of the Plena Voice Alarm System Compliant with standards for emergency sound systems IEC 6-zone system controller Built-in W booster amplifier 12 Business and emergency control in- and outputs. Both four-wire and three-wire schemes are supported. A built-in W booster amplifier provides the power for the emergency call channel and BGM. Up to eight call stations can be connected. Additional Plena Booster Amplifiers can be added as a spare, to provide two-channel operation or if the total power requirement exceeds W maximum W per 6 zones.

Multiple messages can be merged to form one integrated message. As the basis of the Plena Voice Alarm System, the controller has all the essential functionality for compliance with IEC standard, including full system supervision, loudspeaker line impedance supervision, a supervised emergency microphone on the front panel and a supervised message manager. Each can be configured for a message consisting of a sequence of up to eight wave files.

Additional Plena Amplifiers can be added to provide two-channel operation, or for additional power if the total power requirement exceeds W maximum W per six zones.

The Plena Voice Alarm Controller is the heart obsch the voice alarm system. A separate V call-only output provides addressing for an area where BGM is not required but where priority announcements are. An LED meter monitors the output.

The controller can be used as a standalone system with up to 6 zones, or expanded to up to 60 zones using additional 6-zone routers. It is the basis of the Plena Voice Alarm System, and has all the ,bb functionality for compliance with the IEC standard, including full system supervision, loudspeaker line impedance supervision, a supervised emergency microphone on the front panel and a supervised message anager.

Llbb message can have any length within the total available capacity. This gives up to 17 minutes of recording time with CD-quality signal-to-noise ratio. The CD also includes many useful programs, such as MP3-ripping software, a sample-rate converter, various audio and visual tools, and free, MP3-coded music. The BGM output is lnb to the 70 V line, so it is possible to connect a total load of W in a two-channel system combined with a W amplifier.

Six configurable volume-override output contacts are available for overriding local volume controls during priority calls. All booster amplifiers are supervised.

Playback Tape, CD, Tuner. A zone selection, together with this sequence can be configured for each trigger input. The unit has 12 contact trigger inputs for business and emergency EMG calls. The system is configured using DIP switches for basic functionality and a PC for more advanced functions. A total of 16 priority levels can be specified for microphone, call stations and trigger inputs for optimum system flexibility.

All zones may be individually selected from the front panel, and the BGM output level in each zone can be individually set in six steps. The Plena Voice Alarm Controller is the heart of the voice alarm system.

The audio output uses standard analog audio V line switching for full compatibility with the Plena family of public address equipment and Bosch EVAC-compliant loudspeakers. In this way some wave files may be used in various combinations with other messages, optimizing flexibility and the amount of storage space used. The V-technique reduces line losses on longer distances and provides easy parallel connection of multiple loudspeakers.

A built-in W amplifier provides the power for the emergency call channel and BGM. Up to 8 call stations can be connected. The audio output uses standard analog audio V line switching for full compatibility with the Plena family of public address equipment and Bosch EVAC-compliant loudspeakers.

The controller can be used as a stand-alone system with up to six zones, or expanded to up to 60 zones using additional six-zone routers. The messages can be merged to allow even more flexible use of pre-recorded announcements and evacuation messages.

The powerful W output section has six transformerisolated V constant-voltage outputs for driving V loudspeakers in six separate zones. Configuratio software is provided on the CD included with the unit.

Boscu system is configured using DIP switches for basic functionality and a PC for more advanced functions. The messages can be merged to allow even more flexible use of pre-recorded announcements and evacuation messages. The amplifier output is also available as a separate output on V and 70 V.
