miniVES 8003LN/8003LNR/8003R/8003LNR+8003R
integrated PA/VA system for multi purpose architectures
ALL IN ONE INDEPENDENT PA/VA SYSTEM
EN54-4/16 CERTIFIED
midiVES is scalable Public Address & Voice Alarm units suitable for multi-purpose architectures. Devices from midiVES series are voice alarm compact control units containing all components within one compact housing, which meet all the requirements of EN 54-16 and EN 54-4 (certificate of constancy of performance 1438-CPR-0527).
Whole concept of the system is basedon the high quality audio networkdistribution nodes equipped either with two independent 160 W, 320 W or three independent transformerless 500 W class D amplifiers, which distribute 100 V signals to 4, 8 or 16 speaker lines depending on the type. The system also ensures operation of a backup amplifier for the Emergency priority type of signals.
All type of centrals are equipped with integrated backup power supply and EN 54-4 compliant charging unit.
midiVES are designed to be a Plug & Play device with all elements expected from Voice Evacuation Systems; including a built-in fire microphone, touchscreen for global control, DSP, programmable contact inputs and buttons, time scheduler, charger with battery mounting space and expandable memory size for messages –all fitted into IP30 chassis or dedicated 15u rack for midiVES 8003LNR with 8003R.
miniVES and midiVES belongs to the family of independent EVAC systems which can be networked together and extended by desktop zone microphones or fireman microphones via TCP/IP network to provide live announcements and background music inputs. The system has been designed to be wired using CAT5 cables for paging microphones and fibre-optic redundant interlink connections between the systems.
All systems support up to 45 high quality audio signals distributed over 254 devices in the network.
midiVES APPLICATIONS
Communication between microphones and PA/VA control unit is conducted via ETHERNET protocol – possibility of using typical SWITCHES to which microphone cables and then, a single cable are connected to midiVES control unit.
Zone microphone in the office section:
- it is a control unit of the PA system – it enables selection of a zone, activation and deactivation of sound sources or adjustment of sound level.
Zone microphone at the cash desk:
- transmission of verbal alerts;
- freely programmable buttons – activation of a button may result in a transmission of the alert that was already recorded in the system control unit, e.g. calling the store manager, noticing the customers of free cash desk, etc.
Built-in audio input in the control system enables a connection of external devices – transmission of background music of advertisements within the store.
Equipping midiVES control unit with a communication card enables connection of multiple stations, separated from each other by several kilometers, into one system. It is possible to use the existing, logically-separated network infrastructure (VLAN) thanks to the communication between devices via ETHERNET.
Zone microphone at each station enables a transmission of verbal alerts or activation of the automatic alerts from system’s memory not only within the station but also to any speaker zone/s of the whole system, in order to inform the passengers awaiting a train about, for example, changes in traffic scheme or about any danger in the building.
Built-in audio inputs in every control unit and microphone enable a connection of external system signals and alerts coming from a primary, external information systems.
Built-in alert buffering function enables recording of low-priority information that are sent to the speaker lines occupied by primary sources and they are played automatically when the zones are free.
Equipping midiVES control units with communication cards enables connection of multiple industrial facilities into one system. Network cabling between control units made in the form of a fibre loop ensures that any damage of the cabling appearing in any place has no effect on the correct operation of the system.
Microphones located in the main building enable a transmission of verbal and/or automatic alerts to the selected speaker zones in all buildings.
Fireman’s microphone is a top-priority device, providing transmission of the alerts on threats to the people within all or selected buildings.
In case of fire emergency, receipt of control signals from Fire Alarm System or manual activation from the fireman’s microphone, the system sends alerts from the memory located in every midiVES control unit. Single devices operate as autonomous systems, ensuring continuous airing of the alerts on any threats, while total loss of the connection in a part of the systems takes place.
Speaker lines, within open areas, are connected to the central devices with certified surge arresters which ensure safety of devices in case of surges in speaker lines due to lightning discharge.
