DETECTOR INSTALLATION (Continued)
Fusible Link Detection (Continued)
Maximum limitations for the fusible link detection line are as
follows:
Fusible links can be installed with or without fusible link hangers
(see
Section 2 – Components
for description).
Fusible Link Line Limitations When Used with Model
EN-MCU3, MCH3, and NMCH3 Control Heads and CBP-1,
SBP-1, and WBP-1 Pulley Elbows
Maximum # of detectors:
20
Maximum length of cable: 150 ft (45.7 m)
Maximum # of pulleys:
40
Fusible Links Without Hangers
Begin installing links at the terminal bracket. The link is
connected to the far side of the terminal bracket using an “S”
hook. The “S” hook must be crimped closed after the link is
installed. a tight loop is then made in the cable and secured
by the crimp provided. This loop is connected to the other side
of the terminal link (see Figure 4-7) and the cable fed through
the conduit to the next bracket. The cable proceeding from the
terminal link will be used to connect the series links (see Figure
4-8). Series links must be centered in their detector brackets.
after the last link in the series is connected, the cable should
be fed through the conduit back to the control head. Thread
the cable through the hole in the fusible link ratchet wheel. The
line must then be crimped, and the crimp positioned inside the
center of the ratchet wheel.
NOTICE
Crimps must always be used in conjunc-
tion with two cable lengths. Loops are the
accepted method of connecting the cable to
mechanical components.
The crimp must
never be used on a single cable.
Exception:
Single cable crimp allowed in detection and
gas valve ratchet wheel using Stop Sleeve
(Part No. 26317) (Packages of 10: Part No.
24919).
The fusible link line can now be put into a set position by apply-
ing tension to the fusible link line. This is accomplished by using
a 1/2 in. hex wrench on the fusible link line ratchet wheel. The
ratchet wheel will be ratcheted in a clockwise direction until the
spring plate makes contact with the top of the control head box.
The fusible link line is now in a set position. See Figure 4-9.
