• High efficiency class-D amplifier channel(s)
• Switched mode power supply
• Local audio inputs
• Mains and battery operation
• Complete supervision

The basic amplifiers are cost effective alternatives to the regular Praesideo power amplifiers, for situations where no built-in digital signal processing functions, such as equalizers, delay and AVC are required. They do not have a Praesideo network connection. Instead, these amplifiers are connected to the Praesideo network via the PRS-16MCI Multi Channel Interface, which provides the basic amplifier with audio signals and has full control. There are four versions, the PRS‑1B500 (1 x 500 W), PRS‑2B250 (2 x 250 W), PRS‑4B125 (4 x 125 W) and the PRS‑8B060 (8 x 60 W). The basic amplifiers are completely supervised and fault events are reported via the multi channel interface to the Praesideo network controller. The basic amplifiers provide connections for separate group A and group B loudspeakers for each zone, and support class‑A loudspeaker loop wiring. The units should be mounted in a 19″-rack with the included mounting brackets.

• Four audio inputs – two selectable mic/line and two line inputs
• Four line audio outputs
• Eight supervised control inputs and five control outputs
• Audio processing functions
• Redundant network connection

The audio expander inserts external audio into the system and extracts audio from the system. This unit has control inputs and outputs for external interfacing. It can route its audio inputs permanently or conditionally to any of the zones or to other audio outputs. The routing conditions are configured using the configuration software. The audio output can be programmed to get its signal from any of the audio inputs. The equipment can be used freestanding (tabletop) or in a 19″ rack.

• All‑in‑one solution for audio transport on IP‑networks
• Supervised control inputs and outputs
• Supports re‑broadcasting
• EN 54‑16 compliant IP solution
• Configurable as SIP telephone interface (optional)

The PRS‑1AIP1 is a universal, IP‑based audio device supporting VoIP and Audio over IP applications. It is an ideal solution for bridging audio and contact closures over long distance LAN and WAN networks, e.g. in shopping malls, tunnels, in and between railway stations. It extends and interfaces to Praesideo and non‑network based traditional public address systems without the need for a PC during operation. The unit has analog audio inputs and outputs for easy interfacing with optional pilot‑tone supervision for emergency sound purposes. One audio input can be switched to microphone sensitivity with built‑in microphone supervision. Also, the control inputs offer cable and connection supervision. Control inputs and outputs can be used to set up an audio connection to start a remote call, but also to pass remote fault events to the system controller.

Key Points:

• Four OMNEO or Dante™ audio inputs and outputs
• Eight supervised control inputs and five control outputs
• Redundant optical network connection
• Redundant OMNEO network connection
• Headphone connection and VU‑meter for audio monitoring

• 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.

• Redundant network connection
• Power ‘ON’ indication
• Status/fault indications
• Indication that the priority level of destinations is higher than that of the pending announcement
• Supervision of microphone capsule
• Stylish and modern design

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 pushto-talk button, a speaker, and a headset socket. The LBB 4430/00 can be extended with up to 16 keypads (LBB 4432/00 or LBB 4434/00), each with eight programmable keys. Extension with a numeric keypad (PRS‑CSNKP) is also possible.

• 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.
