Amerex Restaurant Fire Suppression System (EX 4658)
DETECTOR BRACKET ASSEMBLY (P/N 12508)
Each detector bracket in the Amerex Kitchen Fire
Suppression System is comprised of three parts the
detector bracket, detector linkage and two EMT fittings.
The fusible link is ordered separately. The bracket serves
as support for the linkage and is attached to a rigid
surface. The linkage supports the fusible link and a
continuous cable run under tension. At a predetermined
temperature the fusible link will separate, relieving tension
on the cable and actuating the system.
This manual will refer to series and terminal detectors. There is no difference in part numbers or dimensions
between series and terminal detectors. A terminal detector is the last or only detector in the network and the
cable must be “terminated” there. A series detector is any detector located between the terminal detector
and the mechanical release module in the detection network.
TEST LINKS (P/N 12891)
Test links are available for conducting functional tests of the detection
system. This device fits the detector linkage in the same manner as the
fusible link, is normally placed on the terminal detector and can be cut,
simulating a fusible link separating under fire conditions
.
CORNER PULLEY (P/N 12309)
The Amerex Kitchen Fire Suppression System uses a “high temperature”
corner pulley to change direction of the cable by 90°. This corner pulley
may be used in environments with temperatures up to 700°F (371°C).
Mounting holes are provided for anchoring the corner pulley
where
allowed by local codes
.
CORNER PULLEY (P/N 16444)
The Amerex Kitchen Fire Suppression System also use a "high temperature"
compression corner pulley to change direction of the cable by 90°. (This
compression corner pulley [Brooks Model CP5] allows complete assembly of
conduit and corner pulleys prior to installing the cable).
PULLEY TEE (P/N 12506)
A pulley tee is used to change the direction of two cables by 90°. This
device can be used with mechanical gas valves and manual pull stations
but
not fusible link detectors
. It cannot be used where temperatures
exceed the range of 32° - 120°F (0° - 49°C).
CABLE (P/N 12553)
Cable is used to run from the MRM, MRM II or PRM, through conduit and corner pulleys to detectors,
mechanical gas valves or manual pull stations. It is 1/16 inch diameter, stainless steel (7 x 7 – 480# tensile
strength) – available in 500 foot (152 m) spools (P/N 12553).
EYEBOLT SUPPORT (P/N 17520)
Eyebolt supplied with one Hex. Nut used to lock the eyebolt into finial
position. Eyebolt is used to support bare cable run in plenum of the
hood in a
Linear Fusible Link Detection System
