A Fully Integrated, Distributed, PAVA, VAD Driver, Fire Telephone

Disabled Refuge System and Emergency Assistance Alarm

All your Emergency Communications and Disabled Alarms on One Network


Vox Ignis introduces Unicorn Voice, the first fully integrated, distributed system taking care of all life safety and disabled access communications using one network.

Unicorn Voice concept covers PAVA, BGM, VAD/Strobe Driver, Fire Telephone and Disabled Refuge as well as integrating Emergency Assistance Alarms in a single solution.

The Vox Ignis design team has over 25 years of knowledge from within the audio industry. This experience results in system that is both easy to install and maintain combined with good aesthetics.

Unicorn Voice simplifies the specification and installation of these systems by offering a one cabinet solution with a range of amplifier, display and switch modules.

The range starts with a standard DAP which can be specified for simple systems which are controlled by connection to the fire system.

Larger buildings including complex high rise applications can be easily accommodated by utilizing a mixture of MAPs and DAPs. These would typically be located in risers covering a number of floors offering large savings in installation over traditional rack systems.

The use of networking in every DAP ensures scalability and removes redundancy on sites allowing them to evolve from single stand alone systems to complex site wide campus scenarios.

The networking allows 64 devices to be connected on a simple network ring of two pair cable (up to 300m per leg) or on multi-mode fibre (up to 2km per leg).


In many countries the fitting of Voice Alarm in high rise buildings is mandatory.

In the UK BS 9999: 2017 requires voice alarm and Fire Telephone to be fitted in buildings which utilise staged evacuation.

Phased evacuation enables a controlled, safe and orderly evacuation of the premises on a floor by floor basis.

To achieve this, a Voice Evacuation system complying with BS5839-8:2013 and Fire Telephone system complying with BS5839-9:2011 must used. This enables the senior fire marshal to be able to communicate with the fire wardens on each floor to coordinate the evacuation, and for the fire warden to be able communicate the status of the floor.

Where escape stairs have been designed for phased evacuation, the width of the escape stair can be reduced therefore increasing the space to let within the building.

Guidance on this reduction is given in BS9999:2017. This can only be done in conjunction with the use of a Voice Evacuation system.

Disabled Refuge is required in all buildings over one floor to allow compliance with the Building Regulations Approved Document B and Equality Act 2010.

Emergency Assistance Calls Systems are required by the Building Regulations Approved Document M, and covered by BS8300-2:2018.
