Emergency Voice Communication System (EVCS)

Emergency Voice Communication System (EVCS)

The Emergency Voice Communication System (EVCS) is a vital life-safety subsystem designed to provide reliable two-way voice communication between firefighters, emergency personnel, and the control room during fire or evacuation scenarios.
It ensures effective coordination and rapid response in critical situations, even under adverse environmental conditions such as high temperature, smoke, and power failure.

Handheld Firefighter’s Telephone Handset

The Handheld Firefighter’s Telephone Handset  is a portable communication device that allows authorized fire and rescue personnel to establish direct voice contact with the control panel or command center via the installed Firefighter’s Jack outlets.

Description & Features:

  • Robust and ergonomic design suitable for field use during fire operations.
  • Heavy-duty, impact-resistant construction with heat-tolerant materials.
  • Equipped with a durable curly cord and rugged plug for quick connection to Firefighter’s Jack.
  • Clear, high-intelligibility audio performance for communication in noisy environments.
  • Magnet or hook provision for secure placement when not in use.
  • Plug-and-talk operation — connection automatically establishes a call with the main control unit.
  • LED call indicator and call active tone (optional) for visual confirmation.
  • Designed for use with compatible EVCS main panels and jack units.
  • Complies with EN54-16 or equivalent fire communication standards.

Applications:

Used by firefighting teams to communicate with the fire command center during emergency operations in buildings such as high-rises, hospitals, commercial complexes, airports, and industrial facilities.

Firefighter’s Jack (Stainless Steel)

The Firefighter’s Jack Unit is a permanently installed wall-mounted communication point that serves as a connection interface for the Firefighter’s Telephone Handset. It provides a secure and durable access point for emergency voice communication within the building.

Description & Features:

Front plate constructed from brushed stainless steel for durability, aesthetics, and corrosion resistance.

  • Flush or surface-mount installation options to suit various architectural requirements.
  • Clearly engraved or labeled Firefighter’s Telephone Jack” for easy identification.
  • Protected RJ-type or two-pin socket for handset connection.
  • Auto-detection circuitry that signals the control panel when the handset is connected.
  • LED or lamp indication (optional) for line active or fault status.
  • Fully monitored wiring circuit detects open, short, or ground faults.
  • Compatible with centralized or distributed EVCS control panels.
  • Meets relevant fire safety and voice communication standards (EN54-16 / BS5839 Part 9).

Applications:

Installed at key locations such as stairwells, refuge areas, lift lobbies, and firefighting access points, providing strategic communication links between fire personnel and the main control room.

System Overview

The EVCS ensures that during a fire emergency, communication lines remain operational and clear, even if other building communication systems fail.
It operates independently or as part of an integrated Voice Alarm / Public Address and Fire Alarm Control network.
The system is typically powered through a dedicated, monitored power supply with battery backup for a minimum of 24 hours standby and 30 minutes alarm operation.
