CleverEVAC is a system and suite of dynamic and adaptive EXIT signs that provide increased visibility, audible cues, and negative enforcement options.
CleverEVAC is a tool for Fire Safety Engineers to consider for use in fire engineered / performance solutions and also in designs where an increased visibility EXIT sign is preferred.
Key Features
Leading the product innovation has been a constant focus, with a drive to provide products and systems that improve the way Exit and Emergency lighting are designed, installed and managed.
Some of these innovations include the introduction of LEDs to emergency lights, lithium battery technology, and CleverSparky,® a mobile, cloud-based compliance
management app for smartphones. Zoneworks® XT is a valuable compliance tool for building owners and operators, taking the manual labour element out of the testing process for emergency and exit lighting installations, and centralising the site’s full database, fault reporting, and log-booking.
CleverEVAC is a system and suite of dynamic EXIT signs that provide increased visibility, audible cues, and negative enforcement options. The work conducted by the Fire Safety Engineering Group (FSEG) at the University of Greenwich led to the development of the CleverEVAC Dynamic Signage product range. The FSEG, and also the University of Leeds have provided the required research, experience and trials of dynamic EXIT signage and locatable sound technology.
CleverEVAC is a tool for Fire Safety Engineers to consider for use in fire engineered / performance solutions and also in designs where an increased visibility EXIT sign is preferred.
An extensive library of research and trial data is available relating to CleverEVAC technology for both audible technology of Sound Escape™ and visual enhancements of Dynamic Signage.
A new concept in emergency signage, which I call the ‘Active Dynamic Signage System (ADSS)’, extends the idea of smart buildings to emergency wayfinding, with a new generation of advanced emergency exit signs. Traditional emergency signs are not always noticed in an emergency and cannot adapt to the circumstances of an incident or a changing threat environment, even if they are directing people into potential danger. The ADSS is intended to save lives by addressing these shortcomings - attracting attention when signs need to be conspicuous, redirecting people during an evolving emergency, and automatically identifying, not just an exit route, but the optimal exit route.
The ADSS combines three key safety innovations. Flashing and running green LED lights within the arrow of emergency exit signs make people more likely to notice them and hence spend less time wayfinding. A large illuminated ‘red cross’ through the sign can deter use of exit routes compromised by an incident. And the system can be expanded to identify optimal evacuation routes by responding ‘intelligently’ to an evolving emergency using upto-the-minute situational awareness and advanced faster than real-time evacuation simulations conducted during the incident itself.
These advances bring the humble emergency exit sign into the 21st century.

Original research by the FSEG found that people often didn’t notice static exit signage, whereas significantly more people noticed dynamic exit signage.
This led to the development of the CleverEVAC Dynamic GREEN exit sign to provide an increased visibility of the sign.
Dynamic GREEN is available with a variety of directional options based on your needs. The Dynamic GREEN mode is triggered either by a 24VDC or voltage free open/close signal from the fire detection or other building safety system.
CleverEVAC Dynamic RED X signs can be interfaced to the building’s fire detection or other safety system, as designed by a fire safety engineer.
CleverEVAC Dynamic RED X sign can display a red cross, alerting those evacuating to seek an alternative exit. Using a red cross through the sign has been demonstrated by FSEG research to be effective in conveying negative enforcement.
The Dynamic RED X mode is triggered either by a 24VDC or voltage free open/close signal from the fire detection or other building safety system.
Combining audible locatable sounds including announcements such as ‘Exit Here’, with the increased visibility of dynamic exit signage, can improve the evacuation outcome, especially in conditions of reduced visibility. The SoundEscape™ option is available and fits perfectly into all dynamic exit sign products.
Zoneworks® XT Hive is a real-time, automatic monitoring & testing system for CleverEVAC Exit & Emergency luminaires to assist in meeting mandated testing and reporting requirements under AS2293.1.
Performance solutions can be designed using instruction from the Fire Safety Engineering report that determines what needs to occur within the evacuation system based on events, and the required action, including activating CleverEVAC Dynamic signage. Advanced building management systems can specifically activate a predetermined function within a CleverEVAC fitting or fittings making a “scene of events”. This development can include fire and evacuation modelling systems such as SMARTFIRE® and building EXODUS® evacuation simulation software, and can determine which event and subsequent action can be executed based on inputs from the building’s safety systems, and these advanced modelling systems.
The future of CleverEVAC will allow for the intelligent control of fittings through advanced building management, simulation and modelling software systems.
NOTE: Zoneworks® XT Hive does not test the interface from the fire detection or other system. Testing method of the interface needs to be documented by the fire engineer.
Research, trials and results, by international fire safety professionals Our products have been developed based on research and studies conducted by the Fire Safety Engineering Group from the University of Greenwich, and also at the University of Leeds.
CleverEVAC has also come about as a result of a demand from Fire Safety Engineers and the like, who have approached us about developing new products relating to evacuation.
