Product Spotlight – Crisis EVC Master Station

Search

Emergency Voice Communication Systems (EVCS) are used to provide two-way communication between those inside a building that are in need of assistance with evacuation and the emergency services. 

An EVC typically consists of a central location point which connects to a number of other points, known as outstations, that are situated throughout the building.

They are designed to assist in the orderly evacuation of people who are disabled or use a wheelchair and increase communication during an emergency. They incorporate a number of different devices to achieve this. A typical EVC system will consist of:

Fire Telephones
In most countries, buildings that are over four stories require at least one fire telephone to be installed on each floor. These telephones provide a hardwired, full-duplex communications system and serve as a backup to traditional fire service radio systems.
Disabled Refuge
In the UK, disabled refuge systems are required in all non-domestic premises over one storey or where an emergency exit is by stairs. A disabled refuge allows people that are disabled or wheelchair users to congregate in a safe place while they call for help and wait for assistance.
Assist Call
An emergency assist call must be provided in all disabled toilets within non domestic premises. By integrating this with the Emergency Voice Communication System, all calls relating to disabled communications can be displayed in a single point.
Master Station
A master station is installed at the central location point and connects the system together.

Crisis EVC Master Station Introduction

The Crisis EVC Master Station is ideal for small buildings that are required to have an EVC system. Crisis EVC Master Stations can support up to 8 outstations including type A fixed phones, type B refuge handsfree points, emergency assist call points or jack points (in Far East and Middle East Applications only).

The self-contained enclosure is made from powder coated zintec with a smoked perspex door covering the handset and can be surface or flush-mounted. It houses a master handset, one to four dual line cards and a EN54-4:A2 2006 power supply unit. Cable entry is via 20mm cable knockouts and there is space for one backup battery. 

The Crisis EVC Master Station is controlled by a microprocessor and does not require programming on site; when an outstation is connected, fitted end-of-line resistors are simply moved to the end-of-line.

Active lines are identified by individual LEDs that flash red for emergency voice communication calls, blue for assist calls or flash green for connecting calls as required by BS5839-9:2011.

All Crisis EVCs are designed to fully comply with the requirements of BS5839-9:2011 for use as a fire telephone system (FT), disabled refuge system (DRS) or as a combined system when both fire telephones and disabled refuge call points are required.
