A public address is often a careful consideration of businesses and authority approvals in a number of sectors for life safety. Those who need to make announcements or play background music will always ensure a PA system fit for purpose is installed in the venue, but misperception is often created where voice alarm and emergency sound systems are concerned.
Public address & voice evacuation alarm is predominantly used for life safety environment, with the added benefit of everyday entertainment and informative uses synonymous with those of a standard PA system. It is always worth highlighting that no other sound system will uphold its integrity in a fire or similar emergency in the same manner as a voice alarm is designed to do. A voice alarm is often recommended by a fire risk assessor but will generally always be required in a building subject to a predetermined evacuation plan; it is designed to work for some time without power and is integrated with the fire alarm. Due to the life-saving benefits of a working voice alarm system, the maintenance requirements are regular and detailed within BS 5839-8 and UL standards.
A general PA system & background music is basically designed for broadcast music and messaging to an audience. Background music is not maintained in the same manner as a voice alarm and are not integrated with the fire alarm for alerts.
