Model eHorn is an electronic horn capable of producing two high decibel horn tone outputs from the same unit through internal amplification and tone circuitry.
The Type 4X, IP66 housing is molded from glass reinforced polycarbonate plastic, making it resistant to ultra-violet light and ideal for indoor or outdoor use.
Model eHorn can be used as a stand-alone, high output, audible warning device in any application where voice paging is not required.
Typical applications include emergency warning, start and dismissal, general alarm and evacuation.
