BRACKET <br /> MCH3, NMCH3, <br /> The Model PAC -10 or PAC -200 Pneumatic Actuation <br /> ECH3 <br /> `� � __� � �.i' / CONTROL HEAD <br /> • Cylinder must be used if more than five (5) agent cylinders <br /> require simultaneous actuation. The Model PAC - 10/200 4 <br /> must be used in conjunction with a Model ' PAC-100R <br /> MCH3 /ECH3 /NMCH3 Control Head. The control head is PAa200 <br /> mounted on the Model PAC - 10/200 valve assembly. (! STRAP <br /> Model PAC-10/200 is shipped complete with a mount- LABEL <br /> ing bracket. The cylinder must be mounted vertically with <br /> the nameplate facing out. The bracket must be securely <br /> anchored to the wall using bolts or lag screws. The wall to <br /> which the bracket is attached must be sufficiently strong to <br /> support the pneumatic cylinder. The bracket should never Figure 4-4. Model PAC - 10/200 Pneumatic <br /> be fastened to dry wall or similar material. If this type of wall Cylinder Installation. <br /> is encountered, studs must be located and the bracket fas- 002874PC <br /> tened to them. See Figure 4-4. In order to actuate the agent cylinders from a Model PAC- <br /> • 10/200 Pneumatic Actuation Cylinder, a 3/4 in. NPT x 1/4 in. <br /> NPT bushing must be screwed into the pneumatic cylinder's <br /> • discharge port. A 1/4 in. NPT x 45° 1/4 in. flare type fitting <br /> (conforming to SAE J513c) must then be screwed into this <br /> • bushing. The male straight connector (Part No. 32338) is <br /> • used with stainless steel actuation hose. Also, a Model <br /> PDA -D2 Pneumatic Discharge Adaptor must be installed on <br /> • the valve of each agent cylinder. Pneumatic or stainless <br /> • steel tubing is then used to connect the PAC - 10/200 pneu- <br /> matic cylinder to the PDA -D2 of each agent cylinder valve. <br /> See Figure 4 -5. <br /> MCH3, NMCH3, OR ECH3 <br /> CONTROL HEAD <br /> • w f ✓ <br /> 1/4 IN.
