Installation
INSTALLING ACCESSORIES (Continued)
Manual Pull Station (Continued)
ALTERNATE METHOD OF CONNECTION:
a. Thread 3/4 x 1/2 in. reducing coupling to bushing on
back of each cover assembly.
b. Mount pull station cover(s) directly to wall at select-
ed location so that printing is right side up and read-
able.
5. Install and secure 1/2 in. conduit, pulley tee (if
required), and pulley elbows from each pull station to
release assembly as necessary. See Figure 14.
FIGURE 14
002262
If a pulley tee is used, it must be installed between the
release assembly and first pulley elbow. The ambient
temperature range of the pulley tee is between 32 °F
to 130 °F (0 °C to 54 °C).
6. Feed wire rope from each pull station through conduit
and each pulley elbow to cable lever located at release
assembly.
NOTICE
Make certain that wire rope rides on top
and in center of pulley sheave. If the wire
rope has been spliced to accommodate a
longer run, do not allow the spliced ends
to be within 12 in. (30 cm) of any pulley
elbow or conduit adaptor.
7. Fasten pull station assembly to each junction box (if
junction box is used).
8. Thread wire rope through rear guide hole in manual
trip lever on release. See Figure 14.
9. Pull all slack out of wire rope and thread end through
sleeve, Part No. 4596.
10. Loop the wire rope back up around and through top of
sleeve.
11. Position sleeve approximately 1/2 in. (1.3 cm) and
crimp to secure wire rope. (Use the National
Telephone Supply Company Nicopress Sleeve tool
Stock No. 51-C-887 or equal to properly crimp stop
sleeve.) See Figure 14.
MECHANICAL PULL STATION TO LEVER RELEASE –
To install a mechanical pull station complete the following
steps:
1. Select a convenient location in the path of exit for
mounting the pull station(s) to the wall. Height and
location of pull station should be determined in accor-
dance with authority having jurisdiction.
The total length of the wire rope used for each manual
pull station within a system must not exceed 125 ft. (38
m).
The maximum number of pulley elbows that may be
used per system is 10.
2. Install and secure 1/2 in. conduit, dual/triple junction
box, and pulley elbows from each pull station to
release assembly as necessary.
3. Feed wire rope from pull station through conduit and
each pulley elbow to cable lever located at release
assembly.
NOTICE
Make certain that wire rope rides on top
and in center of pulley sheave. If the wire
rope has been spliced to accommodate a
longer run, do not allow the spliced ends
to be within 12 in. (30 cm) of any pulley
elbow or conduit adaptor.
4. Fasten pull station assembly to each junction box (if
junction box is used).
5. Wire or pin the actuator lever in the ‘‘SET’’ position to
prevent accidental discharge when installing the cable.
See Figure 15.
CAUTION
!
Wire or pin the actuator lever in the ‘‘SET’’ position
before connecting the cable to the lever. Failure to
comply could result in accidental agent discharge.
