example would be in protection of electric

motors or conveyor rollers which contain

bearings that are subject to overheat and

seizure. In this type of application, the advan-

tage of Protectowire is that it may be installed

in direct contact with the critical part, which

ensures quick response.

Spacing

All Protectowire Linear Heat Detector models

have been tested and assigned a listed spacing

by Underwriters Laboratories (UL) and/or

Factory Mutual Research Corporation (FM).

Spacing is a horizontally measured dimension

related to the maximum allowable detector

coverage, and is determined by actual fire

tests which are conducted in accordance with

established approval agency test standards.

It is important to recognize that for open area

protection, the listed spacing represents the

maximum allowable distance between detector

runs, and should be used as the starting point

for detector layout design. Reduced spacing

may be required based upon factors such as

ceiling height and construction, physical

obstructions, air movement, or the authority

having jurisdiction. When Protectowire is used

for sprinkler system activation, special Factory

Mutual (FM) reduced spacing guidelines may

also be applicable. It is mandatory that engi-

neering judgment be applied in determining

final detector location and spacing.

Smooth Ceiling Spacing

On smooth ceilings, the distance between

parallel detector runs shall not exceed the

maximum listed spacing. There shall be a

detector run within a distance of one-half the

listed spacing measured at a right angle, from

all walls, or partitions that extend to within

the top 15% of the ceiling height, as shown in

the illustration.
