Voice Evacuation

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, they do not indicate the nature of the emergency. Phased evacuation using clear, easily understood, pre-recorded messages ensures that even untrained personnel are evacuated speedily and efficiently.

A voice alarm is, however, not simply a public address system connected to the fire alarm panel, it is much more. A voice alarm system has to work when needed during an emergency and is, therefore, fully monitored at all times. A combination of clear pre-recorded messages and live announcements (to selected areas) enable a controlled and gradual or ‘phased’ evacuation. Real time information may be broadcast by the emergency services to prevent people moving into danger.

VA Systems are fully compliant with BS5839-8 and EN60849 and can also be used as a general public address system during normal circumstances.

Electrosonic ensures that the following design parameters are met:

• Interface to the emergency system such as fire alarms

• Adequate amplification and speaker distribution for intelligibility

• System meets all applicable government codes

• Amplifiers with backup power and performance alerts
