The right tone for your installation
The Apollo 58000-010APO offers a choice of 2 evacuation tones/messages. 

The right level of sound 
This is set during commissioning to one of 7 levels of sound, the highest level being nominally 97dB(A).

Flexibility of group addressing
In many installations a fire alarm must be raised by switching more than one Sounder to alert or alarm simultaneously. This is achieved by assigning devices to groups. One command will then switch all devices in the group.

Sounder, Beacon or both
The Apollo Discovery 58000-010APO normally switches both Sounder and Beacon to provide an alert or evacuation signal. 

Location-specific volume setting
Detectors and Sounder Beacons are installed in many different types of environment.
