Electronic sirens engineered for industrial applications. Developed with 4W magnetodynamic unit, these devices are available in multi-tone version (SE 4/29 MS5), selectable via dip-switch, or with continuous sound for use with PLC (SE 4/25 L PLC). The multi-tone version allows volume level (from min. to max.) and sound progression regulation (time required to reach the sound level set).
Ideal choice for industrial and civil applications, from general-purpose signalization to warning of impending dangers.
