Communication Systems LBB 1990/00 Plena Voice Alarm Controller

LBB 1990/00 Plena Voice Alarm Controller

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 IEC 60849 standard, including full system supervision, loudspeaker line impedance supervision, a supervised emergency microphone on the front panel and a supervised message manager.

The messages can be merged to allow even more flexible use of pre-recorded announcements and evacuation messages. The controller can be used as a stand-alone system with up to 6 zones, or expanded to up to

60 zones using additional 6-zone routers. Up to 8 call stations can be connected. Interconnections are made using standard RJ45 connectors and shielded CAT-5 cable.

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, or for additional power if the total power requirement exceeds 240 W (maximum 480 W per 6 zones). All amplifiers are supervised. The audio output uses standard analog 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.

▶Built-in 240 W booster amplifier

▶12 Business and emergency control inputs and outputs

Functions

The controller has two BGM source inputs and a mic/line input with configurable priority, speech filter, phantom power and selectable VOX activation. A total of 16 priority levels can be specified for microphone, call stations and trigger inputs for optimum system flexibility.

The powerful 240 W output section has six transformer- isolated 100 V constant voltage outputs for driving 100 V loudspeakers in six separate zones. The 100 V-technique reduces line losses on longer distances and allows for easy parallel connection of multiple loudspeakers. All zones may be individually selected from the front panel, and the BGM output level in each zone can be individually set in 6 steps. The BGM output is connected to the 70 V line, so it is possible to connect a total load of 480 Watts in a two-channel system combined with a 480 Watt booster.

The output of the booster is also available as a separate output on 100 V and 70 V. A separate 100 V Call Only output is provided for addressing an area where BGM is not required but where priority announcements are. Six configurable Volume Override output contacts are available for overriding local volume controls during priority calls. A LED VU-meter monitors the output.

Up to 255 messages can be stored in the internal

16 MB flash ROM, without a need for battery backup.
