Bulletin 855H General Purpose Electronic Horns

Rockwell Automation celebrates the utmost achievements in the evolution of industrial audio design by introducing a new line of General Purpose Electronic Horns. This new line produces a sound output of 108 dB (A) maximum, which is suitable for most mid-range industrial and institutional, single-status signaling applications. Each device provides multi-tone and volume control capabilities. Offered in two mounting versions, the GP Electronic Horns directly retrofit into most machine panel cutouts or 4" electrical backboxes where traditional electromechanical horns are mounted.

Electronic horns bring significant advantages over dated electromechanical horns. Electronic horns outlive their electromechanical equivalents due to non-moving parts and highly reliable electronic designs. Reliability prediction methods suggest the life of an electronic horn to be in excess of 2 million hours, while electromechanical horns last approximately 500 hours due to high mechanical stress on the various moving parts including the diaphragm.

Features

Three tones are available in the GP Electronic Horn range
Stepless volume control via potentiometer is used rather than mechanical screw to accommodate fluctuating ambient noise
No need to upsize power supply due to lower current consumption
No back EMF at switch off
GP Electronic Horn rated UL Type 4/4X/13, IP66 (surface mount) or 3R/13, IP54 (semi-flush mount)
Housings made out of heat and shock resistant, corrosion-free, UV-stable plastics suitable for harsh environments and outdoor applications
cULus Listed and CE Certified
