Public Address (PA) systems and VA (Voice Alarm) systems provide a simple & effective means of direct contact with passengers or visitors leading to emergency evacuation or emergency information delivery. Pre-recorded emergency messages are delivered with simple & concise information that people can understand and react to quickly and safely.

LB Foster delivers a comprehensive package if this critical solution including survey, choice and siting of the speakers, acoustic survey to establish the best solution for a particular application. distribution of the speaker circuits and installation including control panel integration.

  • firefighters can easily use an emergency microphone to make their own announcements to ensure a quick and safe evacuation.
  • modern PAVA systems now require fewer amplifiers and are much easier for staff to use – especially useful in a small organisation where personnel have multiple roles.
