HELIX™ PCU

Fire Suppression System

For multiple pressure switch circuit installations (See Figure 4.8.4b):

Begin at the last Pressure Switch, located farthest from the STRIKE Control Unit. Route either
end of the Pressure Switch Extension Cable (P/N 24703

XX or 21539

XX) to the next Pressure

Switch.

See Section 3.6.5 for all requirements for conduit, junction boxes, and outdoor

installations. If conduit is used, it must be 3/4” conduit.

Any excess length in the

extension cable must be coiled and stored.

Do not cut, pinch, crush, or chafe any electrical

wiring or connectors during installation.

Repeat Step 1 for any remaining Agent Cylinders and Pressure Switches in series.

At the first Pressure Switch, route the blunt cut end of the Pressure Switch Lead Cable (P/N
24414

XX) to the inside of the STRIKE Control Unit enclosure through the selected knockout.

This circuit may be routed through the same conduit as the actuation circuit if used. Any
excess length in the cable should be pulled into the STRIKE Control Unit enclosure.

Do not

cut, pinch, crush, or chafe any electrical wiring or connectors during installation.

At the last Pressure Switch, connect the Pressure Switch connectors to the extension cable
connectors [(M) to (F); (F) to (M)].

At the remaining Pressure Switches, connect the (6) connectors as shown, creating a circuit
loop [(M) to (F) x 3].

Termination of the Pressure Switch Lead Cable to the STRIKE Control Unit is performed in
Section 4.9.

Ensure the Pressure Switches and associated cables are fully installed and

connected before proceeding to prevent any fault conditions.
