OmniCALL - Emergency Voice Communication System (EVCS)

OmniCALL* is a fully monitored EVCS platform designed for clear, reliable communication during an emergency. It supports both loop and radial outstations within the same system and can be networked across large or multi‑building sites, providing a flexible and scalable solution for modern buildings.

Networkable EVCS, Compliant by Design

OmniCALL is a modern Emergency Voice Communication System (EVCS) designed to provide clear, dependable communication between building occupants, building management and emergency services during an incident.

Built around a unique 2‑core architecture, OmniCALL supports both loop and radial outstations on the same system. This provides greater design flexibility than single-topology alternatives, while simplifying installation and reducing cabling requirements.

OmniCALL meets the requirements of BS 5839-9 and BS 8893, helping ensure that emergency communication systems remain compliant,
reliable and easy to manage.

Architecture

Networked System Capability

OmniCALL systems can be networked to support larger buildings, campuses or multi‑building developments. Networking allows multiple control panels and expansion panels to operate together as one integrated system.

Inclusive and
Accessible Design

OmniCALL is designed with accessibility in mind, supporting refuge communication systems that allow people who cannot immediately evacuate to request assistance.

This allows assistance alarms to be integrated into the wider Emergency Voice Communication system without requiring separate monitoring equipment.

Designed for Modern Buildings

From commercial buildings and transport hubs to healthcare facilities and education campuses, OmniCALL provides a scalable platform that can grow with the needs of the building.

What is Emergency Voice Communication (EVC)?

Emergency Voice Communication systems provide two‑way communication between building occupants and a central control point during an emergency. EVC systems handle fire telephones, disabled refuge communication points, steward telephones and accessible alarms.

These systems allow people within the building to request assistance and allow emergency teams to coordinate response and evacuation more effectively.

Why choose OmniCALL?

Built for BS8893 and beyond

OmniCALL is designed for the latest EVC standards, including BS5839-9 and BS8300, and is ready for BS8893 compliance. It supports both current requirements and the expectations of future guidance.

Faster installation with 2-core wiring

The use of 2-core fire rated cabling reduces copper, lowers installation cost and makes routing easier on site. It is well suited to busy buildings and retrofit projects where access is limited.

Non polarity dependent connections

Terminations are non-polarity dependent. That cuts down on wiring errors, protects against accidental damage and keeps commissioning time on schedule.

Loop and radial in one system

OmniCALL supports both loops and radials on the same Master Station. This helps with awkward floorplates, phased work and partial system upgrades, without forcing a full rewire.

Clearest audio

OmniCALL provides clear, effective communication using full duplex Type A audio and speech steered Type B outstations. The system is designed so users can hear and be heard even in noisy or challenging conditions.

Frequently Asked Questions

What are the benefits of having one system for loop and radial?

OmniCALL allows loop and radial outstations on the same Master Station. This simplifies design, gives more flexibility on site and makes it easier to extend or part-upgrade systems without starting again.

No. There is no fixed distance limit between remote units, they can be placed anywhere on the loop. Total loop distance depends on the number of outstations, up to a maximum of 1.5 kilometres per loop.

A single loop can support up to 32 outstations plus 32 assistance alarm kits. An OCCPL Master Station supports up to 128 outstations and 128 assistance alarms across four loops or radials. The OCCPS variant supports up to 32 outstations and 32 assistance alarms across four loops or radials. Networked systems can reach 512 outstations (and more where required) and 512 assistance alarms.

Traditional loop systems often use 4-core cable. OmniCALL uses 2-core fire rated cable for loops and radials. This halves copper use, cuts cable cost, reduces terminations and lowers the chance of polarity mistakes. It can also make it easier to reuse existing cabling when replacing earlier Baldwin Boxall ranges or existing two core loop and radial systems.

No, the OmniCALL master station and network expansion panels have been designed to have batteries for 24 hours quiescent (plus 3 hours operation) within the enclosures. Please speak to our team if you require longer battery back up.

Both the OCCPS and OCCPL master stations are fitted with one line card which provides either one loop connection or four radials. Optional line cards are supplied with each providing either one loop or four radial connections. Each master station can be fitted with three additional line cards.
