E2S
Disaster Siren and Alarm
The A141 high output disaster siren and alarm from E2S has an output at 1 m in excess of 140dB, louder than a jet engine on full power at takeoff. With a power increase from 100W to 400W, the output of the A141 is substantially higher than the A140 it replaces, giving it an effective warning range of between 500 and 750 m depending on atmospheric conditions. The unit has a choice of 32 user-selectable warning tones and is powered from either 24VDC or 115/230VAC.
