• Records calls for automatic playback to previously occupied zones (call stacker)
• Acoustic feedback suppression by recording a call with delayed broadcast (time shifter)
• Possibility to monitor a call before broadcasting
• Records and/or plays back up to eight calls simultaneously
• Stores up to 16 calls

The Call Stacker is a small unit that records calls that cannot be sent to all required zones because some are occupied by a higher priority call. The unit can store up to 16 calls in high‑quality format with a maximum of three minutes for each call, including chimes and pre‑recorded messages. Playback of a call can start while it is still being recorded. The unit can record and/or playback up to eight calls simultaneously. More units can be added to a system in order to increase the number of recordable calls. Units can be connected to the Praesideo network at any place.

Each button has two additional indicators for user feedback, related to the configured functionality of that button.
Up to four PRA-CSE can be connected to one call station. Using extension keypads for zone selection allows all zones to be accessible and visible at the same time. It shows a complete status overview of selected and occupied zones or zones with faults.
The extension keypad is delivered with a metal coupling plate and patch cable to link it to a call station or other extension keypad. The front cover can be easily removed to insert labels with up to three lines of text per button and a header section on top.

• Connects a remote call station to the Praesideo network via CAT‑5 cable (up to 1 km)
• Powered by the Praesideo network and/or local power supply
• Two supervised control inputs
• Built‑in DSP for audio processing functions
• Complete supervision of the unit

The PRS‑CSI is an interface between a single remote call station, PRS‑CSR, or a remote call station kit, PRS‑CSRK, and the fiber optical Praesideo network. It uses CAT-5 cable for the connection to the remote call station. The CAT‑5 cable, carrying digital audio and control data, can be as long as 1 km. The length of the CAT‑5 cable is not a part of the Praesideo optical network length. This considerably increases the overall possible length of the optical network, especially in cases, where the call station is located far from the rest of the system. The call station interface can get its power from the Praesideo network, and/or from a local power supply. It is fully supervised.

• Eight freely programmable selection keys
• Serial data and power interface to call station basic
• Up to 16 keypads can be connected to one call station basic
• Activation indicator for each key
• Stylish and modern design

The call station keypad is used in combination with the call station basic to make manual or pre-recorded announcements to any assigned zones, to select the zones or to execute pre-defined actions. The call station keypad has eight programmable buttons, each with a two-color status LED.

• Eight programmable control inputs linked to 16 outputs
• Two serial interfaces to call stations or other keypads
• Up to 16 keypads can be connected to one call station

The call station keypad module is used in combination with a basic or remote call station module to make manual or pre-recorded announcements to any assigned zones, or to execute pre-defined actions. It is functionally equivalent to the LBB 4432/00 Call Station Keypad. One of the main applications is the development of fireman’s panels. However, since the call station keypad has eight programmable input connections, each with two associated output
connections, it is also suited for other control applications.

• Call station kit for making custom made-call station
• Connectors for 3 alarm buttons or lockable key switch
• Connector for 15 programmable buttons
• Connector for microphone and loudspeaker

The PVA-CSK call station kit is a call station printed circuit board (PCB) for the PAVIRO system. The circuit board allows an application-specific call station to be installed, such as a fire department call station. The call station kit is based on the call station, but has been optimized so that it is easy to adapt to different application areas. In addition to the stem microphone that is used with the PVA-15CST, a dynamic EMERGENCY microphone such as the LBB 9081 can also be connected.

• Basic open frame call station for custom call panel solutions without LCD
• Supervised hand‑held microphone with helix cable and loudspeaker included
• CAN‑interface for selection switches and status indicators
• Connections for power LED and status LEDs
• Dual OMNEO IP‑network connection and redundant Power over Ethernet

The basic call station kit is an open frame call station to create dedicated full custom operator panels for PRAESENSA Public Address and Voice Alarm systems. It has the same functionality as the PRA-CSLW, but without LCD user interface to facilitate easier mounting in operator desks or in wall‑mounted fireman’s panel enclosures.
It comes with a hand‑held supervised omni‑directional microphone for close talking with press‑to‑talk button
and a small monitor loudspeaker. The kit has a CAN‑bus interface on RJ12 to a PRACSEK Call station extension kit for connection of selection switches and status indicator LEDs, or to connect to a full custom control board with switches and indicators. The interface is compatible with the PRA-CSE and one to four of these devices can be connected. The kit only requires a connection to an OMNEO IP‑network with Power over Ethernet (PoE) for communication and power supply combined. It can be configured as business and emergency call station. The PRA-CSBK is considered a component that must be installed in a final product. The final product must be reconfirmed to meet applicable EMC directives.

• Numeric keypad for zone selection and user access
• Serial data and power interface to call‑station basic
• Can be combined with normal call‑station keypads
• LCD for user feedback
• Stylish and modern design

The Call‑Station Numeric Keypad is used in combination with a basic or remote call‑station. The call‑station provides the microphone and press‑to‑talk key, while the numeric keypad can be used for user access, zone and zone group selection. It works together with call‑station keypads for pre‑configured actions. The built‑in LCD provides feedback to the user.

• Capacitive touch
• Programmable zone selection
• Modern aesthetic design
• Powered from PLM‑8M8
• Loop‑through to connect with either more Call Stations or Wall Control Panels

The PLM‑8CS PLENA matrix 8 Zone Call Station is an accessory of the PLM‑8M8 PLENA matrix 8 channel DSP Matrix Mixer, and like any good accessory it has a complementary aesthetic design, but behind the good looks and sleek design, there is a product of substance and usability.
With one touch, the call station can call either a single zone, or a user defined group of zones. Installation couldn’t be easier; Powered over standard CAT 5 from the PLM-8M8, the unit’s communication is via RS485, this means that multiple call stations can be daisy‑chained together reducing cable runs and installation time.
