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.
