Underwriters Laboratories (UL File 864 9th Edition) requires that all fire and smoke alarm devices allow electrical supervision of not only the device, but also the corresponding leads. The SR Products Electro Thermal Link (ETL) falls into this category.

Correspondingly, SR Products, LLC have developed a new addressable range designed to fully comply with this UL mandate. The ETL is now available in both temperature ranges (165°F and 69°C) to UL 864 9th Edition standards.

The new link incorporates a stainless steel cage for better protection, and smart circuitry which allows fire panel/control panels to constantly monitor both the unit for continuity and ground fault interruption, or lead wire failure.

Important Note: The new UL 864 9th Edition requirement only affects the 165°F and 69°C ETL units. For any customers requiring non-UL certified ETL's in temperature ratings above 165°F, we can build existing product according to demand.
