Voice Alarm Systems






Research has proven that in an emergency people will react without confusion or panic if they receive a clear, intelligible message. Bells and sounders only give a warning, what that warning is, is never clear. Phased evacuation using clear, easily understood, pre-recorded messages ensure that even untrained personnel are evacuated speedily and efficiently.

PAVA Services offer systems manufactured by Application Solutions Ltd and Baldwin Boxall Communications Ltd. whose systems are already in use in some of the most important and prestigious buildings throughout the world.

Where are Voice Alarm systems used? A Voice Alarm / Voice Evacuation system could be installed in all offices, factories, warehouses, shops, sports stadia, cinemas, theatres, schools and public buildings. Integrating with any fire alarm system to ensure that alert and evacuate messages are broadcast clearly and intelligibly. Operating automatically means that the system will not be dependent on an operator controlling it, unless the Fire Officer elects to take charge.

In a Voice Alarm or Voice Evacuation system all critical signal paths from the Fire Officer’s microphone, through the amplifiers to the end of the loudspeaker lines, are monitored. Battery backup comes as standard. The power supply and internal battery charger are also fully monitored. This ensures that the system is always available when it is needed most, during an emergency.

PAVA Services Voice Alarm systems are designed specifically to meet the life safety issues contained within BS5839 part 8 and EN60849. If you need to broadcast clear unambiguous emergency messages from a voice alarm system, PAVA Services can advise, design and plan the system to suit your needs.
