Space savings are significant, as the ultra-thin & compact EX-FC1
has main unit body dimensions of only W20 0.787H80

Slim & compact

Connections are made by simply inserting the leak detection sensor
cable leads into the male snap connector SL-CP1, then pressing down
until the connector snap-locks!
This saves the user the time and the trouble of stripping the insulation
from each lead before attaching the leads to terminals.

EX-FC1 is a simple wire-saving unit for exclusive use with EX-F71/72 leak
detection sensors.
The EX-FC1 integrates the outputs from up to 8 leak detection sensors
into a single OR output, allowing for significant wiring space savings.
* Even with only one leak detection sensor connected, an OFF signal is output

if the sensor detects liquid leakage, or if the unit has been installed incorrectly.

In addition to an output indicator which allows users to verify output
status, there are 2 built-in operation indicator lights (normal
operation / malfunctioning) for each channel.
The indicator lights (normal operation / malfunctioning) enable verification
of leakage detection status and correct installation of leak detection
sensors, all at a glance.

Newly Released Wire-saving Unit Made Especially for Connecting
Leak Detection Sensors!

Saves wiring! Now connects up to
8 leak detection sensors 3 indicators provide operational confirmation

Connects easily with one-touch connector

Takes up 8 input terminals, one for each of
the 8 leak detection sensors connected.

Only 1 input terminal is needed to handle
connection to 8 leak detection sensors!
