Emergency Voice Communication System
OmniCALL
OmniCALL is our Emergency Voice Communication System, designed to make system behaviour predictable for the people who rely on it, while keeping commissioning straightforward for the people who install it.
At the heart of OmniCALL is a patented* approach that supports both loop and radial wiring from the same control equipment. That means you can choose the topology that suits the building without changing out the head-end. A Master Station provides clear call identification, logical call handling and an interface that’s easy to use.
- Loop and radial wiring on the same system
- 2-core non-polarity-dependent cabling
- Touchscreen Master Station with visual call identification
- Compliant with BS 5839-9:2021, ready for BS 8893:2024
- Designed and manufactured in the UK, 7-year warranty
*Protected by UK Patent GB2605125. Additional patents pending EP4302472.
EVCS Components
OmniCALL supports the full range of EVC outstations. Every outstation sits on the same supervised circuit and reports to the same Master Station, which helps keep the system consistent across a site.

Expansion Panels
Network Panels
Networking panels allow an EVCS to operate as one coordinated system across a building or site, rather than as separate, isolated panels. Calls and status information are shared across the network, so the operator can see where a call is coming from and manage it quickly and confidently.
Touch Screens & GUI
Touch Screens
TYPE A OUTSTATION
Fire Telephone
Handset-based call points for firefighters in lobbies, shafts and plant areas. These are also used for steward telephones in stadia and managed-evacuation venues where clear, direct voice communication is required.
TYPE B OUTSTATION
Disabled Refuge Call Point
Hands-free outstations for designated refuge areas. A single button initiates the call and two-way speech follows without needing to lift a handset. These units support accessible use and clear communication when someone may be waiting for assistance.
TYPE C OuTSTATION
Combined Call Point
Ancillary
Emergency Assistance Alarms

BS 5839-9
Code of practice for the design, installation, commissioning and maintenance of Emergency Voice Communication systems. The baseline standard for any UK EVC installation.
BS 8893
Requirements and test methods for EVC system components. OmniCALL is ready for BS 8893:2024.
BS 9999 & BS 9991
BS 9999 covers non-residential buildings; BS 9991 covers residential. Together they define when and where disabled refuges and fire telephones are required.
Approved Document B
Building Regulations guidance for fire safety in England. Specifies EVC provision in buildings where stair-dependent evacuation applies.
BS 8300-2
Specifies usage for emergency assistance alarms.
Equality Act 2010
Building owners and occupiers are expected to make reasonable provision for everyone using the building. A properly specified EVC system is how that duty is discharged in multi-storey buildings.
EN50130-4
Alarm systems - Electromagnetic compatibility. Product family standard: Immunity requirements for components of fire, intruder, hold up, CCTV, access control and social alarm systems.

Supporting your specification
In practice, EVC requirements don’t sit in one place. Fire strategies, building type, evacuation approach and accessibility obligations all influence what’s needed and where. If you share drawings and an early brief, we can advise on quantities, topology options, Master Station siting and likely integration points before the design becomes difficult to change.
System design support
Send us the drawings and brief. We’ll return an outstation schedule, topology recommendation and approved installer options for your area.
Datasheets, installation manuals, how-to guides and configurator software are in our Downloads Hub, available without registration.
CPD for design teams
We offer CPD sessions on EVC system design and BS 5839-9. Sessions are tailored to your team’s level and project context.
We commission to BS 5839-9, issue Certificates of Compliance and supply EVC log books. Ongoing maintenance contracts are available throughout the system’s life.
Our voice alarm and emergency communication systems can support the wider sustainability and operational objectives of BREEAM-assessed buildings, including TM65 calculations.
