INSTALLING THE DETECTION SYSTEM
Before the following procedures can be completed, the detection
design must already be completed. These installation instruc-
tions are identical for single, double, and multiple-tank systems
except for the number of hazard areas to be covered.
NOTICE
Inform customer that fusible links should
not be exposed to ammonia-based chemical
cleaners or steam.
NOTICE
No attempt is to be made to disassemble,
repair, or clean a Model SL or Model A-PC
fusible link. The complete assembly must
be replaced if there is any sign of potential
malfunction.
1. Based on the requirements listed in the “System Design”
section, mount the detectors in their predetermined loca-
tions.
2. Run 1/2 in. conduit from the regulated release mechanism
trip hammer assembly knockout hole to locations selected
for mounting the detectors.
Note: Before assembling the conduit and fittings, make
certain all ends are carefully reamed and blown clear of
chips and scale. Inside of pipe and fittings must be free of
oil and dirt.
When changing the direction of conduit, use only ANSUL
pulley elbows, except, at the top of the regulated release, it
is acceptable to use the Conduit Offset Assembly.
Note: If stainless steel scissor linkage is used in the system
while using conduit offset assembly, the following limitations
must be observed:
• Maximum number of elbows – 16
• Maximum number of detectors – 15
• Maximum length of 1/2 in. EMT Conduit – 150 ft (45.7 m)
Part No. 435546 and 435547 are the “scissor” style series
and terminal detector assemblies. These detector assem-
blies use a detector linkage assembly which does not
require the wire rope to be threaded through the linkage
assembly while it is being fed through the detection system.
“Scissor” Style Linkage Installation
1. Secure the conduit to the detector bracket using the two
1/2 in. steel compression fittings on the series detector
bracket or the single 1/2 in. steel compression fitting on the
terminal detector bracket. See Figure 5-22.

NOTICE
Do not use zinc die cast compression connec-
tors on the detection conduit lines as these
will not withstand the normally high tempera-
tures experienced in the plenum area.
2. For a terminal detector located in a duct or header opening,
secure both sides of the detector bracket with conduit, as
shown in Figure 5-23.
