Two-way communication that keeps everyone accounted for when it matters most.
What is an ECVS?
Not everyone can simply walk out when an alarm sounds.
A fire alarm initiates an evacuation. What happens next depends on how well your building and your systems support the people inside it. For most occupants, following an illuminated exit route is straightforward. For those with mobility impairments, or anyone who becomes isolated or disoriented during an incident, the situation is considerably more complex.
An emergency voice communication system (EVCS) addresses this directly. It provides a reliable two-way communication link between people who need assistance, emergency marshals managing the evacuation and the fire and rescue services coordinating the response. Rather than leaving vulnerable individuals to wait in silence, an EVCS gives them a means of making their location known and receiving clear instructions while help is on its way.
At Incognito Systems, we design and install EVCS solutions tailored to your building layout and the specific needs of the people who use it, as part of a complete and compliant fire safety setup.
Disabled refuge areas A disabled refuge is a designated space within a building where a person unable to use the stairwells or fire escapes can wait safely for assistance. An EVCS connects these refuge points directly to a control panel, allowing the person waiting to communicate their location to rescue teams and receive updates on the evacuation in progress. Without this communication link, a refuge area provides shelter but leaves its occupant with no means of alerting anyone to their presence.
Emergency assist alarms For non-domestic premises, an emergency assist alarm in every disabled toilet facility is a requirement. These alarms alert rescue teams to the location of a person requiring assistance, ensuring no area of your building is left without a means of raising the alarm. Fire telephone systems Hardwired full duplex fire telephone systems provide a dedicated communication channel between key points in the building, the control panel and the fire and rescue services. Operating independently of the main power supply with battery backup, they remain functional throughout an incident and form a core part of any compliant EVCS installation.
Under the Equality Act 2010 and the Regulatory Reform (Fire Safety) Order 2005, businesses have a responsibility to ensure that all occupants, regardless of mobility or ability, can be evacuated safely. An EVCS is a central part of meeting that obligation in any building where the layout or occupancy profile means that a standard evacuation route is not accessible to everyone.
As well as legal compliance, there is a straightforward practical argument. Knowing that every person on your premises has a means of communicating during an emergency, and that rescue teams can locate and reach them efficiently, reduces both risk and response time when seconds genuinely count.
An EVCS works best when it sits within a broader fire alarm system.
Fire detection and alarm systems
In a building spread across multiple floors or a large footprint, a single alarm tone gives occupants no indication of where the fire is or which route is safest. A PAVA system allows specific messages to be broadcast to specific zones, directing people on each floor or in each area according to the actual situation rather than triggering a blanket response.
PAVA systems
A PAVA system broadcasts spoken instructions to your building as a whole, directing the majority of occupants towards exits and assembly points. An EVCS operates in parallel, maintaining direct two-way contact with individuals who cannot follow the standard evacuation route. Together, the two systems ensure that every person in your building is accounted for and supported throughout an incident.
Emergency lighting and suppression
Clear escape routes, active fire suppression and reliable communication form the core of any effective life safety strategy. An EVCS complements both, ensuring that people waiting in refuge areas or requiring assistance remain in contact with rescue teams even as other systems are working to contain the fire and keep exit routes visible.
Why Choose Incognito Systems for EVCS?
Every EVCS installation begins with a detailed assessment of your premises. We map out the building layout, identify where refuge areas are required, establish where fire telephone points need to be positioned and design a system that provides complete coverage for everyone on site.
All installations are carried out to the relevant British Standards and independently verified through our SSAIB accreditation. Full certification and documentation is provided, giving you the compliance records you need for fire safety inspections and insurance purposes.
Ongoing maintenance is built into our service from the outset. EVCS systems require regular testing and inspection to remain operational and compliant, and our maintenance packages ensure that nothing is left to chance between scheduled visits.
What is an EVCS and how does it differ from a PAVA system?
An EVCS is a two-way communication system that connects specific points in a building, such as disabled refuge areas and emergency assist points, to a central control panel and the fire and rescue services. A PAVA system broadcasts voice messages to the building as a whole. The two serve different purposes and in many buildings both are required as part of a complete life safety setup.
Is an EVCS a legal requirement?
For buildings with multiple floors or areas that are not accessible via standard escape routes, an EVCS is effectively required to achieve compliance with current fire safety legislation. The specific requirement depends on your building type, layout and occupancy. We can advise based on an assessment of your premises.
What is a disabled refuge area?
A disabled refuge is a designated space, typically within a protected stairwell or lobby, where a person unable to use the fire escape can wait safely for assistance. An EVCS connects that space to the building's control panel, allowing two-way communication between the person waiting and the rescue teams responding.
Do disabled toilet facilities need an emergency assist alarm?
Yes. An emergency assist alarm is a requirement in all disabled toilet facilities on non-domestic premises. It provides a means of alerting rescue teams to the location of a person requiring assistance from within the facility.
How often does an EVCS need to be tested and serviced?
Regular inspection and testing is required to ensure every component of the system remains fully operational. Our maintenance packages are structured around the relevant servicing intervals, with all visits documented and available for inspection as part of your compliance records.
Can you install an EVCS alongside an existing fire alarm system?
Yes. An EVCS can be integrated with your existing fire detection and alarm infrastructure. We assess compatibility as part of the design process and manage any integration work required to ensure all systems operate together correctly.
