Emergency Voice Communication System (EVCS)

Design, installation, management, remote monitoring and maintenance of integrated public address and EVCS

EVCS (or Emergency Voice Communication System) is a fixed, monitored, maintained, bidirectional voice communication system to assist the orderly evacuation of disabled, mobility impaired people and support firefighter communications during an incident. It is used in high rise and large buildings or sites where radio communication may be unreliable.

Importantly, new fire evacuation standards are being enforced to BS8629 from 2021 onwards and enshrined into the Regulatory Reform Order (RRO). Are you compliant?

The Equality Act (formerly The Disability Discrimination Act) and Building Regulations Document makes it the responsibility of all companies, nationwide, to ensure access to buildings and services is available to everyone.

A and B Types

A Types – use a telephone handset for communication and are identified as a fire or fire steward telephone

B-Types – use a hands-free intercom (wall-mounted with a call button)

Recommendations

  • EVCS require a dedicated circuit (except outstations)
  • Need to be located in low background noise areas (< 40 dB (A)
  • Need to be usable 24/7/365 and not locked
