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

 

Interconnections:

• Two RJ45 jacks
