Protectowire Linear Heat Detector Installation Accessories

LHD Installation Accessories

The Protectowire Company offers an assortment of approved fasteners and splicing devices to facilitate installation for both standard and special applications. Protectowire supplied fasteners are generally designed to lightly clamp the detector which enables a tension to be applied progressively. This method is better than arrangements which apply a high tensile load at the end of each run or clamp and compress the sensor cable so tightly that the inner insulation becomes damaged. To ensure a trouble-free installation, only Protectowire supplied or recognized fasteners should be used.

WAW Clips, Type N and P
WAW Clips may be used for ceiling or wall mount applications, as well as at corners.   The fastener is a clip which wraps around the Detector and is available in either nylon (WAW-N) or polypropylene (WAW-P) material depending upon the installation environment.  As a general rule, nylon WAW-N’s are preferred for applications where the ambient temperature is expected to be low such as freezer warehouses.  The installation temperature range for the WAW Series fasteners is -40°F (40°C) to 190°F (88°C).
