which utilizes a heavy duty zinc plated

clamp suitable for both indoor and outdoor

use. These versatile fasteners may be used for

mounting Protectowire on cable trays, con-

veyors, angle irons, I-beams, bar joists, etc.

PDR Miniature Drive Rings

This fastener is a PROTECTOWIRE develop-

ment, and consists of a nail and hook assembly.

It is easy to apply, with or without the special

driver. The Detector is hooked into the hook

eye after the nail is driven and slides readily

through it. On any uneven surface such as

rough plaster board, the slight separation from

the surface tends to straighten the detector line

and improve the finished appearance.

Both the nail and the hook eye are hardened

steel, alloy plated. Nails are 1 1/4 inches

(3.2cm)

long for use on a variety of supports.

With a little care and patience the nails can be

driven into mortar joints with light taps, to

provide an easily applied fastening to masonry.

Adhesive Cable Mounts

In some installations, the use of mechanical

fasteners that require drilling into the mount-

ing surface is prohibited, or simply not possi-

ble. An example of this type of application is

the mounting of Protectowire directly onto

large power transformers. For many of these

situations, the only viable solution is to utilize

an adhesive mounting system consisting of

EMS Cable Mounts, PLT Cable Ties and an

approved industrial adhesive. The EMS Cable

Mounts and PLT Cable Ties are constructed of

black weather resistant nylon, and when used

with the approved adhesive, are suitable for

outdoor use.

As a cautionary note, the use of adhesive

mounting should be limited to applications

which will not be subjected to temperature

extremes or harsh chemical environments

that could effect the service life of the adhe-

sive and cause it to fail prematurely.

Installation environments which contain sol-

vents, strong acids or alkalis should always be

avoided. In addition, the adhesive mounting

system shall not be used where the continu-

ous operating temperature will be less than

0°F (-18°C) or exceed 180°F (82°C).

RMC L-Bracket

The RMC Series L-brackets consist of a steel

bracket, WAW Clip and snap button and are

often used for mounting Protectowire to the

rim seals on floating roof tanks. The brackets

are 6.7 inches (17.0 cm) long and contain five

mounting holes which allow for multiple

height adjustments of the Detector’s installa-

tion position. The brackets are available in

plated steel or stainless steel models, and may

be used in a wide variety of common installa-

tions and applications.

Staples

Staples installed with staple guns or drivers

are generally not recommended for fastening

Protectowire Linear Heat Detector. Most

commercially available staple guns which use

flat staples will crush or pinch the Detector

causing shorts and unwanted alarms.

Experience has also shown that even in the

most skillful hands, some quantity of staples

will be improperly placed during installation

thereby penetrating the outer jacket and

injuring the Detector internally.

In rare situations where the use of staples is

considered to be the only appropriate means
