Strong power alert siren AS400

AS400M / SO4 SERENNEL SERIENNS The AS400M siren range has been designed for a wide range of industrial signaling applications requiring a very powerful output signal. The sirens integrate a fractional power motor that causes a high speed to the high speed forcing air through the split front cover, creating a unique penetrating sound. The units offer a single-level alarm when powered, but they can be pulsed or modulated by simply switching on or off to produce the conventional sound of a "screaming" siren. The units are robust and suitable for use in difficult environmental conditions. The AS400M siren produces a low frequency sound that is perfect for the signaling of medium size areas. For maximum coverage, it is advisable to raise the unit over surrounding buildings. The design allows a termination inside the housing.
