Section 2 System Description and Components
2.4.3 Discharge Manifold
(supplied by installer)
A discharge manifold may be used in a multiple cylinder system to direct the ow of agent from two or more
cylinders into a common pipe. Manifolds are to be supplied by the installer and may be constructed out of
threaded or welded pipe and ttings. When two or more cylinders are grouped together with a common
manifold, they must be of the same size and ll. A manifolded cylinder arrangement must be tted with
a manifold check valve. Suggested manifold dimensions and arrangements are shown in Figure 2.4.3a,
2.4.3b, 2.4.3c, 2.4.3d, and 2.4.3e. Actual manifold size and dimensions must comply with hydraulic ow
calculations derived from the Janus Design Suite® software.
