The call station basic can make manual or pre-recorded announcements to any pre-assigned zones. The call station basic has a microphone on a flexible stem, a push-to-talk button, a speaker, and a headset socket. For more information download the Datasheet below...

- 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. For more information download the Datasheet below...

- Redundant network connection
- Power ‘ON’ outputs
- Status/fault outputs
- Output for a monitoring loudspeaker
- Priority indication of busy target zones

The call station kit is used to make custom-made call stations, with the same functionality as the LBB 4430/00 Call Station Basic. The call station contains a built-in limiter and speech filter for improved intelligibility. An external power supply can be connected to the call station kit. Two supervised control inputs provide power supply status information. For more information download the Datasheet below...

- 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 kit is used in combination with a call station kit or call station basic to make manual or pre-recorded announcements to any assigned zones, or to execute pre-defined actions. For more information download the Datasheet below...

- Connects to call station interface via CAT-5 cable
- Up to 1 km from Praesideo optical network
- Uses standard Praesideo keypads for extension
- Built-in limiter
- Powered via CAT-5 and/or local power supply

The PRS-CSR is a call station with the same functionality as the basic call station, LBB 4430/00, but it uses CAT-5 cable for its connection to the Praesideo network. It connects, one-to-one, to the call station interface, PRS-CSI, which is part of the Praesideo optical network. The CAT-5 cable, carrying digital audio and control data, can be as long as 1 km. For more information download the Datasheet below...

- Connects to call station interface via CAT-5 cable
- Up to 1 km from Praesideo optical network
- Uses standard Praesideo keypads for extension
- Built-in limiter
- Powered via CAT-5 and/or local power supply

The PRS-CSRK is a PCB with the same functionality as the remote call station, PRS-CSR, but without its housing and other components. It is for the construction of custom applications. It connects via a CAT-5 cable, one-to-one, to the call station interface, PRS-CSI, which is part of the Praesideo optical network. For more information download the Datasheet below...

- 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.
