CONTROL HEAD INSTALLATION (Continued)
2. Multiple Cylinder actuation Using Model PaC-10 Pneumatic
actuation Cylinder
The Model PaC-10 Pneumatic actuation Cylinder must be used
if more than five agent cylinders require simultaneous actua-
tion. The Model PaC-10 must be used in conjunction with a
Model MCH3/ECH3/NMCH3 Control Head. The control head is
mounted on the Model PaC-10 valve assembly.
The Model PaC-10 is shipped complete with a mounting bracket.
The bracket must be securely anchored to the wall using bolts
or lag screws. The wall to which the bracket is attached must
be sufficiently strong to support the pneumatic cylinder. The
bracket should never be fastened to dry wall or similar material.
If this type of wall is encountered, studs must be located and the
bracket fastened to them. See Figure 4-4.

In order to actuate the agent cylinders from a Model PaC-10
Pneumatic actuation Cylinder, a 3/4 in. NPT x 1/4 in. NPT
bushing must be screwed into the pneumatic cylinder’s discharge
port. a 1/4 in. NPT x 45° 1/4 in. flare type fitting (conforming to
SaE J513c) must then be screwed into this bushing. The Male
Straight Connector (Part No. 32338) is used with stainless steel
actuation hose. Pneumatic tubing or stainless steel actuation
hose is then used to connect the PaC-10 pneumatic cylinder
to the valve cap assembly of each agent cylinder valve. See
Figure 4-5.
NOTICE
Pneumatic tubing (copper) used for remote
cylinder actuation shall have an outside diam-
eter of 1/4 in. with a minimum wall thickness
of 1/32 in. (0.8 mm). This is commonly known
as refrigeration-type copper tubing. all tubing
fittings shall be of the 1/4 in., 45° flare type
conforming to SaE J513c.
Compression type fittings are not accept-
able.
The Model PaC-10 pneumatic cylinder can actuate a maximum
of ten agent cylinders with a maximum of 100 ft (30.4 m) of
pneumatic tubing.
