EVAC systems (emergency evacuation systems) broadcast emergency messages, and possible evacuation, in environments such as hospitals, industries, shopping centres, schools, etc. Such Evac systems can also be installed in environments with very high background noise and potentially explosive atmospheres (ATEX).
L'sound evacuation system or EVAC system is a advanced systemwhich comply with EN 54-16 and EN 54-24, have the capacity to self-diagnosis continuous of its components and total redundancy: even the failure of one or more parts does not affect the dissemination of the emergency message.
In environments with a large public presence, a Evac plant is indispensable, to ensure a sound and alarm system capable of handling emergencies by means of a guided evacuation. The system can also be used not only to broadcast alarm messages, but also other sound communications in ordinary conditions, such as music or announcements. It goes without saying that in the event of an alarm, the highest priority is given to emergency messages.
In principle, the decision to install a Evac plant of sound for evacuation is the responsibility of the owner of the structure or the employer on the basis of the risk assessment and the regulations in force. The risk assessment is carried out by the Fire Brigade, which, after an on-site analysis, issues the CPI (Fire Prevention Certificate) on the basis of the inspection carried out. However, there are some fire prevention and/or occupational safety regulations that explicitly require their installation for certain activities.
In particular, facilities that must equip themselves with Evac plant are:
There are several types of compact sound evacuation systems on the market: with built-in microphones, with internal power supply, with double redundancy, with indoor or outdoor amplifiers, with loudspeakers certified to operate in ATEX environments...
Irbema distributes exclusively in Italy the brand 4EVACa system of full audio evacuation e customisabledesigned for operators in the security and fire-fighting sector.
Overview of 4EVAC audio systems
4Evac C500 è un sistema audio compatto di allarme vocale, contenuto in un’unica consolle predisposta per installazione a parete.
Si tratta di un’unica soluzione certificata ben oltre i requisiti minimi, veloce da installare e semplice da gestire grazie al software di configurazione con grado di protezione IP30 e che è dotata di tutte le funzionalità previste dagli standard e dalle normative: EN54-16:2008, EN54-4:2006, ed EN50130-4:2011 (CPR: 0560-CPR-152190001/00).
La parte principale dell’impianto EVAC è il modulo di amplificazione DA200 che può offrire fino a 200W di potenza su linea a tensione costante 100V.
Il Compact500 è disponibile in 3 versioni a loro volta configurabili:
200W on 2 channels of 100W (to serve 2 zones or provide redundant A/B line on a single zone)
400W on 4 channels of 100W
600W on 6 channels of 100W
Il 4Evac C500 è dotato di 4 slot per alloggiare i moduli di amplificazione DA200.
3 slot sono destinati agli amplificatori in uso corrente nel sistema mentre il quarto è sempre dedicato all’amplificatore di riserva su cui viene commutato l’audio nel caso di malfunzionamento di uno degli altri 3.
Questo rende possibile ottenere 3 configurations depending on the number of DA200 modules installed (1, 2 o 3). Each configuration can be used in at least 2 different ways (DA200 on 2 lines or in bridge on 1 line)
Built to meet the highest expectations while remaining user-friendly, flexible and cost-effective, IMPACT:
halves installation and maintenance costs.
is the ideal system for a modular configuration.
is designed to save space even on large installations.
Why choose Impact?
Modular design that makes the system flexible and scalable
Switching arrays (SW6 modules), which make expansion very easy
To create more zones, it is possible to work with SW6 remote concentrators in the field that save wiring (certified cables are expensive)
Remote diagnostics and maintenance
The INPUT-OUTPUT module (4E-GPIO) can be remotely positioned to control or receive alarms from other devices/central units
Very well organised and simple software package for programming the control unit
Huge networks can be developed without additional hardware such as modems (which would not even be certified). A network can comprise a maximum of 255 addresses (it is possible to combine networks with Compact 500 system)
Very simple rack construction with few cables (patch)
Very simple system design with only controller and amplifier
Amplifier with built-in battery charger and high resistance that makes it usable for small and large projects such as football stadiums
Touch screen console covering up to 255 zones
MAZE is the new system designed by 4Evac to implement and innovate the functionality already present on the Impact system.
access to 250 additional audio channels compared to conventional Impact Controllers.
MAZE offers a range of EN54-certified solutions for Audio over IP applications.
Compared to the Impact system, MAZE guarantees low latency, lossless audio over IP transmission, where up to 250 audio channels can be distributed within a Local Area Network (LAN) for background music with uncompromising quality.
SYSTEM - Local Net (L-Net) functions as a daisy-chain bus between the main system unit and remote network devices, such as paging consoles or additional GPIO interface.
maximum 8 devices per port
maximum 16 devices per main unit
L-Net is used to move interfaces and control panels from the central location in the system to remote control points. The local network is fully monitored and can be configured in a redundant ring topology, providing two secure paths to the remote device. Maximum point-to-point distance over CAT5 cable is 250 metres, with the possibility of extension up to 2000 metres over multimode optical fibre.
Global Net (G-Net) is a redundant network ring in which multiple system controllers can be connected into one fully transparent system. It is used to reliably synchronise data between all connected locations. The maximum point-to-point distance on CAT5 cable is 250 metres, with the possibility of extension up to 2000 metres on multimode optical fibre. The total capacity of the network is 254 devices, including the main system controllers and peripherals, such as microphone stations.
Why choose a 4EVAC sound evacuation system?
1. Expanding audio zones
Zones expandable via SW6 module. The evac control units of other brands stop at a maximum of 6 audio zones. In the case of 4EVAC the number of zones can be expanded up to 36 audio zones.
2. Length-free connections between consoles
4EVAC's technology, in addition to the normal connection possibilities between control panels, allows a connection of up to 2km with fibre optics (as opposed to the classic BUS used by other brands' systems, which reaches a maximum of 250/300m).
3. Loop connections
Thanks to the longer cable lengths, several 4EVAC control panels can be looped together, even in large areas such as apartment blocks, public areas, shopping centres, multiplexes,... Thanks to the looped connection, redundancy of the connection between them is guaranteed.
4. Guaranteed self-diagnostics
The front control panel of the 4Evac systems returns alarm and fault signals that may also be present in the loudspeaker lines in real time, thus providing all the system self-diagnostics required by the EN54 family of standards.
5. The only EVACs with integrated microphone
The 4EVAC sound evacuation control panel is the only one to be equipped with a certified and legally required call and general alarm microphone (4E-FMP for VVFF use) already integrated in the machine and included in the price. It is also possible to connect other microphones in the network, to increase the ability to communicate alarm and evacuation procedures from several areas.
6. Quick and easy assembly
To mount the machine, it is simply necessary to attach a metal bracket to the wall to which the 4EVAC control unit is attached. The system arrives ready to use, can be assembled in half an hour and does not need to purchase any additional accessories, which are mandatory to comply with current standards. The machine is also plug and play.
