CONTROL HEAD INSTALLATION (Continued)
2. Multiple Cylinder actuation Using Model PaC-10 Pneumatic
actuation Cylinder (Continued)
If the system design requires the use of two control heads for
multiple cylinder actuation, a maximum of 25 ft (7.6 m) of tubing
is allowed between the two control heads and the PaC-10 cylin-
der. See Figure 4-6. If a PaC-10 cylinder is not utilized, there is
a maximum of 25 ft (7.6 m) of tubing for the two control heads
and up to four cylinders or a maximum of 18 ft (5.4 m) of tubing
for the two control heads and five cylinders.
DETECTOR INSTALLATION
Fusible Link Detection
Fusible links are always used in conjunction with the Model
MCH3 Mechanical Control Head. after mounting the cylinder
and control head, the fusible link line can be installed. The first
step to installing the fusible link line is to install the detector
bracket(s) over all protected appliances and in each duct. See
Section 3 – System Design for detector placement guidelines.
Note: Only A-PC-style Fusible Links can be used.
Connect the fusible link brackets together using 1/2 in. conduit
and the conduit connectors supplied in the detector kit (Model
FLK-1). a PYRO-CHEM KITCHEN KNIgHT II corner pulley
must be used whenever a change in conduit direction is neces-
sary. The conduit is connected to the control head through a
knockout in the upper left-side corner.
In general, fusible links centered in the detector brackets are
connected in series using 1/16 in. (1.6 mm) diameter stainless
steel cable. The spring plate in the control head maintains
tension on this series of fusible links. If the tension is released
for any reason (e.g. a fusible link separates), the control head
will operate and actuate the system.
