Applications:
FIRE DETECTION, INC.FIRE DETECTION, INC.
There are many commercial and industrial applications for linear heat detection. Linear heat detection works in many environments smoke detection will not. Linear heat detection can withstand harsh chemical environments and outdoor applications as well. Additional jacket coatings can be applied over the standard PVC outer covering for special applications.
Special Outer Jacket Coatings1. (PVC) Standard, for all typical indoor applications2. (Nylon) Heavy Duty projects and outdoor applications3. (Polypropylene) For chemical environments4. (Guide-wire) A steel outer cable wound around the LHD cable to allow for long distance suspension of the cable in open areas.
