12. Remove cocking lever and fully insert Lock Pin (Part No.
438031) through the hole in the trip lever on the left side of
the release. (The release mechanism cannot be actuated,
nor can enclosure cover be replaced until the lock pin is
removed.) See Figure 5-34.

14. Verify each detector linkage assembly, with correct fusible
link, is in the detector bracket, located fully toward the termi-
nal detector side.
NOTICE
Due to the close adjustment between the trip
hammer and cable lever assemblies, use only
the particular fusible link(s) selected for instal-
lation in each detector, including terminal
detector, to ensure correct adjustment when
performing Steps 15 and 16.
15. Raise trip hammer 3/8 in. to 1/2 in. (9.5 to 12.7 mm), pull
all slack out of wire rope, and tighten set screws on locking
clamp.
16. Lower tension lever to “DOWN” position and inspect the base
of the wire rope locking clamp to make certain that there is
a minimum of 1/4 in. (6.4 mm) and a maximum of 3/8 in.
(9.5 mm) clearance between the base of the trip hammer
locking clamp assembly and the cable lever assembly. See
Figure 5-36. (If clearance is not between 1/4 in. (6.4 mm) or
3/8 in. (9.5 mm), raise tension lever, loosen set screws on
locking clamp and repeat Steps 15 and 16.)
CAUTION
Make certain the hook assembly with the ANSUL fusible
link in place is located toward the terminal detector side of
each bracket. Failure to do so may restrict travel of detec-
tion line, causing system to malfunction.

17. Test detection system in accordance with the Testing and
Placing in Service Section, Page 6-3 – 6-4, of this manual.
18. When testing has been completed, cut off excess wire rope
in the regulated release assembly, leaving approximately
2 in. (51 mm) of wire rope below the locking clamp.
