Open Rack Storage

Figure 24 illustrates Protectowire Linear Heat

Detector installed in a section of a palletized

open rack. When used in open single and

double row racks protected by sprinklers, one

line of detection cable is needed at each in-

rack sprinkler level. Wider racks may require

additional Detector runs at each level. To min-

imize the risk of mechanical damage to the

Detector, the preferred method of mounting

is to locate the Detector in the longitudinal

flue space and attach it to the horizontal load

beam at each sprinkler line level.

If the racks have no sprinklers and are more

than 16 feet (4.9m) high the Detector should

be run at two levels. If the racks are more than

32 feet (9.8m) high, the Detector should be

run at three levels, etc.

Floating Roof Fuel Storage Tanks

Figures 25, 25A and 25B illustrate Protectowire

Linear Heat Detector installed around the

perimeter of a floating roof fuel storage tank.

The Detector may be run in the area between

the primary tube seal and the secondary

weather seal, or alternately attached to the foam

dam and placed directly over the secondary

weather seal. The type of mounting clip will

vary according to the structure of the tank to be

protected, however, the RMC Series L-Brackets

are most commonly used.
