The system may be utilised as an addition to existing alarm systems, run independently as PA / Evacuate only or may integrate to the system 5000 range  fire alarm systems to provide fire alarm alert with general PA "voice over". In fact almost any combination is possible including continuous background music with additional power supplies. 

The unit can operate as a traditional sounder and via the audio output, transmit pre-recorded evacuation messages and provide manual intervention with free speech from a PA system. 

The System 5000 allows the voice messages to be activated on a global or zonal basis allowing for phased evacuation in larger buildings. Both red (fire) and yellow (evacuation) callpoints can be used on the same system, each activating different pre-recorded messages. As with the System 5000's existing industry standard radio smoke & heat sensors, sounders and manual callpoints, the Audio Sounder Unit is powered by a battery module with a 5 year life using just regular alkaline batteries! In addition the Audio Sounder unit can be locally powered to provide greater audio output or more continuous use as with PA applications. 

The System 5000 can now provide a truly integrated fire detection and voice evacuation solution without the need for cable and hence disruptive and damaging installation works. Applications include historic buildings, museums, hospitals, nursing homes, hotels and schools and large buildings such as warehouses where cabling becomes impractical and costly.
