REMOTE PULL STATION INSTALLATION (Continued)
The Pull Station can be surface mounted or flush mounted.
For flush mounting a RaCO #232 4 in. (102 mm) deep elec-
trical box or equivalent must be used (dealer supplied). It is
connected to the releasing device using 1/16 in. (1.6 mm)
diameter stainless steel cable. The cable enters the pull station
box through the center hole in the bottom, top, either side,
or the center back hole. The cable enters the control head
through the top-center knockout. The cable must be enclosed in
1/2 in. EMT conduit with a PYRO-CHEM KITCHEN KNIgHT
II corner pulley at each change in conduit direction. Maximum
limitations for the Model RPS-M Remote Mechanical Pull Station
are as follows:
Model RPS-M Cable Run Limitations When Used with
Model ECH3, MCH3, EN-MCU3, and NMCH3 Control Heads
and CBP-1, SBP-1, and WBP-1 Pulley Elbows
Maximum length of cable: 150 ft (45.7 m)
Maximum # of pulleys:
40
after mounting the pull station box and conduit, feed the stain-
less steel cable from the releasing device, through the conduit,
and into the pull station box. Feed the cable through the bushing
and through the hole provided in the pull handle. Loop the cable
through the pull handle and secure it with the crimp provided
(see Figure 4-17).

Cut and thread the cable through the hole in the latching arm
of the control head and pull the cable tight. Crimp the cable
approximately 6 in. to 8 in. (152 mm to 203 mm) below the
latching arm.
Note:
NFPa-17a requires the pull length to be no
more than 14 in. (355 mm).
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).
Pull the pull handle until the crimp touches the latching arm. See
Figure 4-18. Coil the excess cable in the pull box and attach the
cover plate with the four screws provided. Insert the pull handle
into the cover plate and insert the plastic break rod.
Note:
Excess wire rope must be coiled in the pull station box,
not in the control head.
