Directions For Use of PWSC Splicing Connectors

2. Install wires as shown below making sure the entire 1/2”

(1.3cm) portion of bare Protectowire Linear Heat Detector

conductor is embedded in splicing connector.

4. Using 4”-5” (10.1cm-12.7cm) of SFTS tape, starts at least 2”

(5.1cm) before connector and wrap the splice. Stretch and

overlap each wrap of tape by 1/4-1/2 the width. SFTS tape

is recommended specifically for outdoor or high humidity

installations.

5. Finish the splice seal by wrapping “Scotch/3M” brand “Super

33+” or “No. 35” electrical tape over the SFTS sealant.

3. Secure Protectowire Linear Heat Detector by tightening

the connector screws. Plastic screw turrets may be

trimmed with snips or utility knife for easier taping.

Remove insulation from each wire leaving 1/2” (1.3cm) of

bare Protectowire Linear Heat Detector conductor, preserv-

ing 3/8” (.9cm) of insulation from bare wire back to the cov-

ering.

Attach these to the Detector ends, insulate and tape like a

splice:

Flexible Leads

Flexible leads are furnished with most Protectowire systems for

connecting Protectowire Linear Heat Detector to terminals.

Installation efficiency will be gained by care-

fully planning the routing of each Protecto-

wire run. This will ordinarily be done on the

basis of a scale drawing of the area to be pro-

tected, consideration of the location and spac-

ing information presented in the Detector

Location and Spacing Section of this manual,

and other less obvious factors which may be

observed at the site.

Protectowire is designed to respond rapidly to

changes in temperature caused by a fire.

Therefore, its mounting hardware must pro-

vide adequate support at temperatures which

are at least as high as the alarm trip point.

Fasteners should typically be spaced every 5-

10 feet (1.5-3m), or as may be necessary to

prevent the wire from excessive sagging which

puts undue stress on the wire at the fastening

points. Improper installation and fastening

may also subject the Detector to physical dam-

age in some process areas or interactive appli-

cations, such as rack storage facilities.

Fasteners

Protectowire approved 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 dam-

aged. To ensure a trouble-free installation, only

Protectowire supplied or approved fasteners

should be used. The use of non-approved fas-

teners may physically damage the Detector

thereby causing “false alarms” and in some

cases void the Detector’s warranty.

Several categories of approved fastening

devices are available to hold the detector in

place without injuring it. These include:

• General Purpose - These fastening devices are

commonly used in area detection applications

where the Detector will be installed on the

ceiling, roof or side walls.

• Cable Tray Applications - These versatile fas-

teners are intended to mount the Detector to

a variety of cable tray configurations, but may

also be used for many other mounting situa-

tions such as conveyors, angle irons, I- beams,

bar joists, etc.

• Pipe Mounting - A category of fasteners

which allow the Detector to be mounted

directly to associated sprinkler pipes in vari-

ous pre-action and deluge systems.

• Messenger Wire - When installing Protectowire

with optional stainless steel messenger (sup-

port) wire, eyebolts and turnbuckles are

required. Ideal for spanning large open areas or

where mounting support structures are limited.

General Purpose Fasteners

WAW Clips - One of the most versatile fasteners is

the WAW. They may be used for ceiling or wall

mount applications, as well as at all corners

(turns) except in messenger wire, drive ring or

pipe mounted installations. The fastener is a clip
