Amerex Restaurant Fire Suppression System (EX 4658)
JOB LINKS
Four temperature ratings of the Job Links are available. They are
constructed of two metal struts held intension by a small, glass bulb that
ruptures at the appropriate temperature rating. The detector bracket
(P/N 12508) will support either the Globe Type ‘K’ fusible links or the
Job links, and the same detector limitations apply for both types of
detector.
FUSIBLE LINKS
Four temperature ratings of fusible links are available.
They are of the electric solder type link which will melt at
a predetermined temperature allowing the two halves of
the link to separate.
FUSIBLE LINK TERMINATION KIT (PN 17515)
The kit consists of four major components, their part
numbers and quantities per kit are provided in the
table. The kit contains the necessary cable segments
and hardware for the beginning and end termination of
the Linear Fusible Link Detection network.
CABLE SEGMENT – LINK TO LINK
PN17354 – 24” CENTERS
PN19155 - 12” CENTERS
The Link to Link cable segment PN17354 insures that the
links in the linear fusible link detection system are spaced at the maximum 24” centers to center distance.
The Link to Link cable segment PN19155 places links 12” apart center to center. It will assist in locating links
in the hood duct opening when the two ducts are an odd distance apart.

Load Limit: Maximum Load – 50 lbs. (22.68 Kg)
Minimum Load - 3 lbs. (1.37 Kg)
CONDUIT OFFSET (P/N 12507)
The conduit offset is used to allow a smooth transition for cable runs into or
out of the MRM, MRM II & PRM without using pulley elbows. It may be used
with the detection network, manual pull stations or mechanical gas valve
actuation network. The use of this device does not reduce the maximum
number of corner pulleys allowed in the system.
THE CONDUIT OFFSET
MAY ONLY BE ATTACHED TO THE ENCLOSURE
OF EITHER THE MRM,
MRM II OR THE PRM
