An emergency voice communication (EVC) system allows firefighters and others to communicate with one another during emergency situations. The system also allows communication with disabled persons and refuge areas.
It is a “System that allows voice communication in either direction between a central control point and a number of other points throughout a building or building complex, particularly in a fire emergency situation” (BS5839-9:2011 3.4).
The Need for EVC
EVC systems are needed in any building where there are disabled people or people who may have difficulty negotiating the evacuation route. Also in buildings with phased evacuation and sports style venues where it will assist stewards with control or evacuation of the site. It is sometimes referred to as:
- Disabled refuge system (DRS) – (TYPE B outstation)
- Fire telephone system – (TYPE A outstation)
- Emergency / steward telephone system – (TYPE A outstation)
OmniCare Loop Wired System
OmniCare is wired in a ring circuit configuration which is self learning through an auto commissioning feature. The ring circuit saves up to 75% on cabling costs compared to typical star wired systems. The ring circuit allows continued operation in the event of a cable break. Therefore, should part the circuit be broken or damaged all of the remote units will continue to function normally.
Care 2 Emergency Voice Communication Systems
The CARE2 system is radial wired using 2 core enhanced cable. Each panel is supplied as a 4-way unit which is easily expandable to up to 16 ways by adding line cards. CARE2 uses dual 2-core enhanced cable for the network loop – less than other manufacturers who generally use dual 4 core.
Like OmniCare, with CARE2 any combination of outstation can be fitted to a single panel, including the disabled toilet alarms.
The system configuration is stored on an internal SD card and programming can be achieved either using a PC or via the front panel encoder and display. Using this facility, customers are able to modify settings such as renaming outstation locations on the panel.
The control panel has a rugged red handset with t-coil, which is housed in a lockable enclosure – secure, robust and easy to handle.
Outstations and Options
The disabled refuge outstation features an output to feed an induction loop amplifier – offering your customer the ability to further enhance their system
Most of the items are also available with a stainless steel finish – which your customer may prefer. Strong, self-adhesive vinyl signs are available to indicate a refuge area (the ‘these premises’ sign is included with all control panels as standard)
There is a plasterboard back box option for the standard disabled refuge units which provides an easy solution when installing in stud partition walls. Another option for the standard refuge remote is the IP66 rated enclosure which enables mounting in external areas such as balconies and open muti-storey car parks
Up to 15 Network Expansion Panels (NEPs) can be fitted on one system (or 14 if installing two control panels). The status of local outstation can be viewed on the screen. A roaming telephone handset can be connected for initial system set up.
Calls can be reset via the key switch or at the control panel. Available with a green or stainless steel finish, the unit can be surface mounted (or flush mounted with bezel).
