Please read this important installation note

*The internal timing is deliberately allowed to vary slightly between units. No attempt is made to make either the ON time or the OFF time exactly the same from unit to unit. This makes it very unlikely that any two units used in the same geographical area at the same time will synchronize, preventing one or both horns from being heard. The components are selected so that the requirements of Rule 35 will be met, regardless of any timing variation.

Please note that the HornBlaster® Fog Horn Timer is not rated for use in confined spaces where explosive vapors may exist. Do not install this unit in enclosed engine or tank spaces of gasoline powered vessels.
