AS400M Series

Industrial Siren

The AS400M range of sirens were designed for a wide range of industrial signalling applications where a very powerful high output signal is required.

The sirens incorporate a fractional horse power motor that drives an internal impeller at high RPM forcing air through the slotted front cover creating its unique penetrating sound.

The units offer a single stage alarm when energised but may be pulsed or modulated by simply turning the power on/off to produce the classic ‘wailing’ siren sound. The units are of robust construction and suitable for use in harsh environmental conditions.

The AS400M siren produces a low frequency sound that is ideally suited for signalling over medium size areas. For maximum coverage it is advised that the unit be raised above the surrounding buildings. Design allows for termination inside the enclosure.
