LINEAR FUSIBLE LINK DETECTION NETWORK – LANYARD SYSTEM
The Linear Fusible Link Detection System provides complete hood fire detection by placing thermal
links at maximum 24” intervals the entire length of the hood. Installing the links in this manner allows
the appliances to be placed anywhere under the hood without having to locate links directly over each
appliance.
A unique system of cable segments, pre-fabricated, has been developed to make the installation of
this system simple and easy. It eliminates the use of conduit, link holders and mounting brackets
under the hood in the plenum area.
The limitations of the Linear Fusible Link Detection System are as follows:
1. Maximum of 20 detection links and (19) Link to Link Cable Segments.
2. Maximum of 30 feet of cable used in the Link to MRM Cable Segment.
3. Maximum of 20 corner pulleys. (either style)
4. Maximum unsupported detection cable length is 8’-0”.
5. Refer to Fusible Link Selection section, page 3-24 of this manual for proper selection process.
The higher setting links are to be used when higher temperatures are encountered with
appliances such as char-broilers.
6. The Linear Fusible Link Detection System is for use in single hood applications, or where
multiple hoods are connected “end to end” only. It cann ot be used for “ back to back ” hood
arrangements or multiple hoods that are mounted in separate locations and are part of a
single Restaurant Fire Suppression System.
