Approvals/Maximum Listed Spacing
Type EPR Linear Heat Detector
UL (25 ft/7.6m)
FM (25 ft./7.6m)
The distance between detector runs shall not exceed the
listed spacing. Reduced spacing may be required based
upon factors such as ceiling height and construction, physical
obstructions, air movement, or the authority having jur isdiction
(AHJ). When Protectowire is used for sprinkler system
activation, special Factory Mutual (FM) reduced spacing
guidelines may also be applicable.
Important Installation Information. Please Read!
Protectowire Linear Heat Detector may be installed at the ceiling level to protect areas within buildings (area protection) in the
same fashion as the more familiar spot type heat detectors. Please refer to the National Fire Alarm Code, NFPA 72, for basic
information on the installation and spacing of linear heat detectors for area protection. For special applications where the
Detector is installed close to the hazard, the manufacturer’s recommendations and/or installation instructions should be
followed. Whenever there is a choice between two or more possible installation procedures, the one which results in increased
protection should be utilized.
For additional installation information on Protectowire Linear Heat Detectors please refer to the Installation/Operation/
Maintenance Manual (MAN 2001E-0603) and the Important Installation Information document (DS-7736) on
www.Protectowire.com.
