The A141 is the latest addition
to our disaster warning range. The new A141 high output disaster siren from E2S
offers significant improvements in sound output and is easy to install.

 It has an effective warning range of between 500m and 750m
(depending on atmospheric conditions and location). With the options of battery
back-up and radio control, the A141 is suitable for the most demanding
installations in quarries, on large industrial and petrochemical sites and for
civil defence requirements. 

Unlike traditional electro-mechanical warning
devices, the high output sounder is lightweight and offers exceptional high
reliability and long life combined with low energy consumption. This means it
is easy to install and requires virtually no maintenance.
