Voice Evacuation (Voice EVAC)

Bells, Buzzers, Horns........ Voice Evacuation systems (Voice EVAC) have their SAY!

Voice evacuation systems typically co-reside with other alarm and emergency based systems to provide spoken alarm and evacuation information and instructions. Commonly integrated with complex/high-end fire systems, VEVAC systems are specially designed PA installations that can be seen in many situations, especially public assembly areas (stations, airports, shopping centres etc..)

Typical voice evacuation messages provide clear information and instructions about the emergency. These spoken messages are often better understood by people in the building, again, especially in public assembly areas.

Voice EVAC Design, Standards & Regulations

Careful consideration to the building design and defined escape routes are extremely important to any conventional alarm or evacuation based system. A VEVAC system has additional design aspects and considerations:

BS5839 part 8 (Voice alarm system design and installation)

This particular section of the fire detection and alarm regulations covers the 'Code of practice for emergency voice communication systems'. It is important to recognise specific design considerations for VEVAC systems, part 8 of this respective British Standard covers these details - you can find out more about these by clicking HERE.

BS5588 part 8 (Means of escape in case of fire for people with disabilities)

This particular section of the fire precautions regulations covers the 'Code of practice for the means of escape for disabled people'. Disabled people (particularly those that rely on a wheelchair for mobility) have specific considerations and needs in the event of an evacuation. For example, use of evacuation routes via stairs or ladders would obviously be restrictive to such disabled persons. You can find out more about these standards by clicking HERE.

BS EN 60849 (Sound systems for emergency purposes)

It is obviously very important that any 'Voice' based EVAC system is well designed so that the audio and spoken messages are clear and intelligible. This standard works together with those above, and provides a basis for consideration the building acoustics when designing a VEVAC system.
