The QRDSis a
general-purpose device which is suitable for a number of different
applications. The HSRS is our flagship HVAC
product intended specifically for HVAC shut-off. Please review the
product chart below to compare the two products:
The following chart compares features and options of QRDS
and HSRS products:
HSRS (wired & wireless) systems are plug-n-play solutions which are
each suitable for both residential and commercial applications.
The QRDS wired system is a
plug-n-play solution that is suitable for commercial use and product
The QRDS wireless system
requires a third-party receiver device (sold separately) with
compatible door/window transmitters. A custom-prepared interface cable
solder-attached to the receiver's internal printed circuit board. In
addition, a hole is to be drilled into the plastic enclosure for cable
routing. (These customizations are not authorized by the receiver
manufacturer & will immediately void the receiver warranty.) As a
result, the wireless solution is considered a home DIY project and is not recommended
for commercial use, product resale, or distribution.
(Instead, you may wish to use the HSRS if
considering a wireless application.)
