• 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.

• Four CobraNetTM audio inputs
• Four CobraNetTM audio outputs
• Eight supervised control inputs and five control outputs
• Redundant Praesideo network connection
• Redundant CobraNetTM network connection

CobraNetTM, developed by Peak Audio, is a network protocol for real-time uncompressed digital audio distribution over industry standard 100Base-T Ethernet networks. Typical applications are room coupling and audio distribution over long distances. CobraNetTM audio channels can be configured as inputs to a Praesideo system, where they can be routed permanently or conditionally to any of the zones or audio outputs. The routing conditions are configured using the configuration software. Calls and background music (BGM) sources can be routed to CobraNetTM channels. Digital audio data is directly converted between an audio system and CobraNetTM, with no other audio processing than sample rate conversion. Control inputs and outputs are provided for external interfacing. The equipment can be used free-standing (tabletop) or in a 19” rack. CobraNetTM is a registered trademark of Peak Audio, a Division of Cirrus Logic, Inc.

• Interface to Praesideo basic amplifiers
• Up to 16 audio channels
• Redundant fiber optic network connection
• Control input and output connections
• Complete supervision

The PRS-16MCI is part of the Praesideo network and acts as an interface to the Praesideo basic amplifiers that do not provide network connectivity. The unit is intended for public address and emergency sound systems. The multichannel interface provides 16 configurable output channels (14 main outputs and two spare outputs). It provides the audio signals to the basic amplifiers and has full control over the amplifiers. It supervises itself and the connected basic amplifiers, and reports fault events to the Praesideo network controller. The unit should be mounted in a 19″-rack with the included mounting brackets.

• Sturdy hybrid network cable
• Dual plastic optical fibers (POF) and copper power conductors
• Low smoke/zero halogen (LSZH) sheet material
• Wide temperature range operation

The LBB4416/00 is a network cable with two plastic fibers for data communication and two copper cores for power supply. It is 100 meters long, and comes without network connectors. LBB4417/00 connectors are fitted after the cable has been cut to the required length

• Public address and emergency sound system control unit
• Control and routing of 28 simultaneous audio channels
• Ethernet interface for configuration, control, diagnostics, and logging
• Digital storage for pre‑recorded messages
• EN 54‑16 and ISO 7240‑16 system certification

The network control unit is the heart of the Praesideo system. The unit routes up to 28 simultaneous audio channels, delivers power to the system, reports faults, and controls the system. Audio inputs can be announcements from call stations, background music, or local audio. The network control unit can be configured for the most complex public address systems. The configuration can be done comfortably and efficiently via a PC. The PC is only needed for configuration. The controller can operate independently of the PC. However, the controller can use a PC to display information on the system status using the software, supplied with the unit. The unit can be freestanding on a tabletop or mounted in a 19″ rack. The PRS‑NCO3 network controller needs PRS‑SW software version 4.0 or higher.

• 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

OMNEO, developed by Bosch, is a network protocol for real-time uncompressed digital audio distribution and control over industry standard IP networks.

• Serves multiple Call Station Clients and/or Telephone Interface Clients
• Controls multiple Network Controllers in extended systems
• Includes a license for a single Network Controller
• Controls user access with selectable rights per user

The PRS‑SWCS PC Call Server is a Windows service connected to one or more Praesideo network controllers via TCP/IP, using the Praesideo open interface. It is used in combination with one or more client applications, such as the PC Call Station Client and the PC Telephone Interface Client, handling all operational requests. The PRS‑SWCS PC Call Server is configured via an included PC Call Server Configuration Client, running on the same computer.

• 12 A battery charger
• 6x 40 A, 3x 5 A outputs
• 150 A back‑up current
• Fully supervised, EN 54‑4 certified
• Under‑voltage and over‑voltage protection

The PLN‑24CH12 and PRS‑48CH12 Battery Chargers are designed for public address and emergency sound systems, to assure that the system batteries are always charged. Rack mountable, the unit charges lead‑acid batteries and simultaneously provides 24 V or 48 V for system components that use 24 V or 48 V exclusively.

• 1, 2, 4, or 8 audio outputs (selection from 100 / 70 / 50 V outputs)
• Audio processing and delay for each amplifier channel
• Amplifier supervision and spare amplifier switching
• Loudspeaker line and loudspeaker supervision (LBB 4428/00 only line supervision)
• Eight control inputs and 1, 2, 4 or 8 control outputs

There are four types of Power Amplifier units in the Praesideo product range. These differ in the number of amplifier channels per frame: one, two, four, or eight. The overall power rating is 500 watts for all of the amplifiers. The Power Amplifiers can be set to 100 V, 70 V and 50 V output tappings. They have short-to-ground and short-circuit detection functions, and can generate their own pilot tone for supervision purposes.
