The Plena Voice Alarm Controller unit 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 54 16 and EN 60849 standards, 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 six zones, or expanded to up to 120 zones using additional six-zone routers. Up to eight 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. 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.



Configuration software is provided on the CD included with the unit. 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 Plena Voice Alarm Router is an expansion unit that can add six zones and 12 input contacts to the Voice Alarm System. It can use the built-in amplifier on the LBB 1990/00 Voice Alarm Controller, and provides inputs and outputs for one or two amplifiers in a multi- amplifier one or two-channel system.

It provides dual channel opera tion for calls and BGM simultaneously to a maximum of six different zones, using two Plena amplifiers. Additionally, single channel operation is possible with only one Plena amplifier.

Multiple routers can also share one amplifier, including the internal amplifier on the controller unit. It is possible to use any number of amplifiers from one up to the number of routers used. The controller supports A/B wiring.

Features:
  • Expand the voice alarm system with six zones

The Plena call station is a stylish, high-quality call station with a stable metal base design, a flexible microphone stem and a unidirectional condenser microphone. It can make calls to selected zones (one to six and all-call) in a public address system built with the Plena Voice Alarm System. In addition to tabletop use, the special design allows it to be neatly flush mounted in desktops. The Plena Voice Alarm Keypad (LBB 1957/00) is an extension adding seven additional keys.

Features:
  • Stylish six-zone call station for the Plena Voice Alarm System
  • Six zone selection keys, all-call key and momentary PTT-key for calls
  • Selectable gain, speech filter, limiter, and output level for improved intelligibility
  • LED indications for zone selection, fault, and emergency state
  • Call station extension provides seven additional zone and zone group keys

 

Functions:

Each call station supports six zone selections. The number of selectable zones or zone groups can be increased by connecting call station keypads (LBB 1957/00). Up to eight keypads can be added with each keypad adding seven zone or zone-group keys.

 

This call station features selectable gain, a selectable speech filter, and a limiter for improved intelligibility. The call station has a balanced line level output, making it possible to position it up to 1000 meters from the controller, using CAT-5 extension cables. With shielded cable, the call station can also be used in an EMC level 5 (heavy industry) environment.

 

DIP switches at the base of the call station select different microphone gain levels, the call station ID, and the speech filter. A service accessible rotary control provides microphone level attenuation. LEDs on the call station show which zones have been selected. Three additional LEDs give visible feedback on the active state of the microphone and the system. Green flashing means standby (chime is sounding). Green indicates microphone active. Amber indicates that the system has detected a fault, and red indicates that the system is in the emergency state.

 

Controls and indicators:

  • Four status LEDsPTT-key
  • PTT status LED
  • Six zone selection keys
  • Six zone selection LEDs
  • All-call key
  • Eight DIP switches
  • Rotary volume control
