Public Address & Voice Evacuation

A ringing bell tells people something is wrong. It doesn't tell them where to go – so many wait to see what others do.

A voice evacuation system gives clear, calm instructions zone by zone: leave now, wait for instructions, use the east stairs. On normal days the same system handles paging and background music.

Why it matters

Clear words move people faster than bells

Studies of evacuations show people react faster to clear spoken instructions than to bells. A voice evacuation system broadcasts pre-recorded or live messages zone by zone – evacuate this floor, stand by on the next – and doubles as a paging and background music system every day.
