In the first quarter of 2010 SR Products launched the fully UL 864 amendment 9 compliant dual responsive electro thermal link (ETL).

For more than 25 years and countless thousands of installations the SR products ETL has stood out as the value for money, safe and efficient thermal release sentinel. The unit that stands guard against smoke or fire threats year after dependable year. We are constantly informed that units have woken up after 20 years and dutifully activated as designed. (Whilst it is very heart warming to hear about such wonderful reliability, we do not recommend that the unit is subjected to such a long period of activity.)

As the product is a true life safety device we strongly advise that a life span of 10 to 15 years is its normal life span at which time the unit should be replaced.

The new ETL, fully compliant with the requirements of UL 864 it now has the ability for a control panel to supervise the unit and the wires connecting it for ground fault, wire damage, continuity therefore ensuring the continued functional ability of the unit is guaranteed.

By adding smart circuitry and a ground up re design of the protection required by this circuitry, and of course compliance with UL requirements, our engineers have successfully created a product that couples the 25 years plus proven design of our original ETL with the ability to report on its own ability to release upon command.

All the above information is in addition to specifications quoted in the technical specifications for our existing product range.

News Release
2 July 2009
Bay City, MI USA

The United States Department of Transportation (D.O.T.) has officially de-classified the SR Product's Electro Thermal Link (ETL)®.  This means the ETL® is no longer Hazmat listed in any category. From this point forward, the world's most popular Electro Thermal Link® can be delivered through regular channels: UPS Ground and Air, UPS Ground and Air and even Parcel Post.  There are no restrictions on packaging or shipping for both domestic and international destinations.

The ETL® was previous listed as a 1.4C explosive device.  We have always believed this incredibly fast response Fusible Link was unfairly classified. And, since 9/11, it has become even more difficult to deliver the ETL® to both current and new customers worldwide. Following successful D.O.T. testing at an accredited laboratory, immediate actions were taken to declassify the ETL® so that it can be purchased as a regular Electro Thermal Link.

The impact of this important ruling by the D.O.T will save our customers not only the additional costs incurred when shipping Hazmat, but provide many other shipping options not available under the Hazmat classification.

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 is in the process of upgrading the ETL in both temperature ranges (165°F and 679°C) to UL 864 9th Edition standards. As a result, SR Products will only be able to offer the upgraded units following the UL advised testing period of between six to eight weeks. In the meantime, we will have limited availability on the current ETL units until the compliant product is available.

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.
