Determine volume of Junction box. This information may be on the
junction box itself usually expressed in cubic inches. If not, measure the
inside length, width, and depth of the box and multiply these numbers
together. This gives you the free volume of the junction box.
If the junction box is round measure the inside diameter and multiply this
number by itself. Multiply this number by 0.78 and record this answer.
Then measure the depth of the junction box and multiply it by the sum of
your rst answer. This gives the free volume of a cylindrical junction box.
Using the table above, subtract the cubic inches per each conductor
which originates outside the junction box and terminates or is spliced
within the junction box. Each conductor that passes through the junction
box without splice or termination shall be counted once. Refer to
National Electric Code 2011, article 314.16 (B).

Product Description
The DC400 system uses a sump sensor to detect the
presence of liquid in the STP (Submersible Turbine Pump)
or dispenser sump. If liquid is detected, the system will
shut down power to the STP or dispenser.
The DC400 system consists of the 404-4 Controller and
either a 2-Wire or 3-Wire sensor. Follow these instructions
for installation of the 404-4 Controller. Franklin Fueling
Systems sensors approved for use with the DC400 system
come with their own installation instructions.

Installation for Alarm Wiring
Important! For all applications, do not exceed the relay
contact rating of 250VAC, 12A.
The relay contacts (Orange / Black and Orange wires)
on the 404-4 controller are normally closed dry contacts
(when power to the controller is applied) that will open
when liquid is detected. This enables the DC400 to be
wired for various alarm notication and monitoring.
Figure 6 shows an example of alarm wiring for applications
that do not require positive shutdown but simply some sort
of visual and / or audible notication. In this example the
alarm light illuminates when the DC400 detects liquid.

Testing
Test the function of the system according to applicable
codes. Test immediately after installation, and at least
annually to verify proper system operation.
Troubleshooting
If the controller relay repeatedly cycles or oscillates
when the sensor is tripped, it is likely that the controller is
switching its own power. Check the wiring diagram and
conrm that the controller is wired properly. Make sure that
the orange / black, red and black wires are tied to power
from the breaker and the orange wire feeds the dispenser.
