4.1.6.4 Two-Sided Pilot Actuation Lines
To maximize distances between cylinders, a tee may be installed extending from the pilot actuation port
of the primary cylinder (after the pilot actuation check valve) to allow the pilot actuation line to extend in
two directions. All guidelines and limits previously stated in Sections 4.1.6 through 4.1.6.3 apply to such
arrangements in addition to the following:
• When utilizing ex hose, the total length of the pilot actuation line from the primary cylinder to the last
slave cylinder in either direction (including any rises or drops) cannot be greater than 100 ft (30.48 m) in
each direction.
• When utilizing copper tubing, the total length of the pilot actuation line from the primary cylinder to the
last slave cylinder in either direction (including any rises or drops) cannot be greater than 100 ft (30.48
m) in each direction.
• When utilizing Schedule 40 pipe, the total length of the pilot actuation line from the primary cylinder to
the last slave cylinder in either direction (including any rises or drops) cannot be greater than 25 ft (7.62
m) in each direction.
• To accommodate the use of the standard Janus Fire Systems® Pilot Actuation Mid Line Tee to allow the
pilot actuation line to extend in two directions, the Janus Fire Systems® NPT Style Pilot Actuation Check
Valve (P/N 10262) along with an adapter hex nipple (P/N 18713 or P/N 19192) is used. A 1/4" (8 mm)
FNPT x FNPT coupling (P/N 99686) is needed to connect the NPT Style Pilot Actuation Check Valve
to the Pilot Actuation Mid Line Tee.
• A vent check shall be installed at both ends of the pilot actuation line downstream of the pilot actuation
check valve.
Refer to Figure 4.1.6.4 for an example of a two-sided pilot actuation line arrangement utilizing ex hose.
