Chapter 4 — System Installation <br /> Page 4 -4 <br /> REV. 2 <br /> NOTE <br /> Pneumatic tubing used for remote cylinder actuation <br /> ' shall have an outside diameter of 1/4 in. with a minimum <br /> • wall thickness of 1/32 in. This is commonly known as <br /> refrigeration -type copper tubing. All tubing fittings shall <br /> • be of the 1/4 in., 45° flare type conforming to SAE <br /> J513c. Compression type fittings are not acceptable. <br /> The Model PAC -10 pneumatic cylinder can actuate a maxi- <br /> mum of ten (10) agent cylinders with a maximum of 100 ft. <br /> • (30.5 m) of pneumatic tubing. <br /> The Model PAC -200 pneumatic cylinder can actuate a maxi- <br /> mum of twenty (20) agent cylinders with a maximum of <br /> • 200 ft. (61 m) of pneumatic tubing. <br /> ►C. Multiple Cylinder Actuation Using Two Control Heads. <br /> If the system design requires the use of two control heads for <br /> multiple cylinder actuation, a maximum of 25 ft. (7.6 m) of <br /> tubing or stainless steel actuation hose is allowed between <br /> the two control heads and the PAC -10 cylinder. See Figure <br /> 4 -5a. If a PAC -10 cylinder is not utilized, there is a maximum <br /> of 25 ft. (7.6 m) of tubing or stainless steel actuation hose for <br /> the two control heads and up to 4 cylinders or a maximum of <br /> 18 ft. (5.4 m) of tubing or stainless steel actuation hose for <br /> the two control heads and 5 cylinders. <br /> rretrow <br /> s i <br /> 1 <br /> Li .r' iC <br /> Figure 4 -5a.
