Wiring Options
Daisy-chain, Multi-drop, or com inations of these with Point-to-point may allow
signifcant savings in total wire and conduit used in installation.
Point-to-Point
(applicable for all sensor types)
Direct wiring of individual
devices to the controller.
Multi- rop:
(S3L™ devices only)
Allows drops from a single
overhead bus. +GF+ SIGNET J-
boxes are very useful in creating
the 3-way junctions that are
necessary in this wiring scheme.
aisy-Chain:
(S3L devices only)
Allows sequential connection
from one device to the next. All
+GF+ SIGNET J-boxes provide
dual conduit ports to simplify this
wiring scheme.

Maximum Current Consumption for S3L™ evices
* The S3L™ communication link between the 8900 and the 8059 is powered by the
8900 and consumes 1 mA maximum. owever, the 8059 External Relay Module
always requires a separate power source for its operation.
Wiring
In order to use this ta le, the total maximum current consumption of all the S3L™ devices
in the system must e known. Refer to the Ca le Length Ta le and add the appropriate
mA values to find the total.
Round up to the nearest column heading in the Ca le Length Ta le a ove or extrapo-
late etween columns to approximate the maximum allowa le ca le length for all S3L
devices in the sytem (regardless of wiring scheme). Notice the influence of wire size
and capacitance on maximum allowa le ca le lengths. Proper ca le selection is
critical, especially when long runs are required in an installation.
• These ta les apply to devices with S3L output only.
• See individual flow sensor data sheets for ca le length limitations.
• See 8900 Instruction Manual for more details.
