EX-FC1
MJE-EXFC1 No.0052-90V
Thank you very much for purchasing Panasonic products.
Please read this Instruction Manual carefully and thoroughly for the correct
and optimum use of this product.
Kindly keep this manual in a convenient place for quick reference.
In case of using sensing devices for prevention of accidents etc. which
damage a human life or properties, be sure to construct the system so
that all of the machinery operates to the safety side. This product itself
does not posses control functions needed for accident prevention or
safety maintenance.
OUTLINE
1
●
This is the simple wire-saving unit which can be connected with max. 8
leak detection sensors.
●
Even if only one leak detection sensor is connected to this product, the out-
put is gained when leak is detected or the sensor is mounted improperly.
●
Since the exclusive snap
male connector (
SL-CP1
) is used for connec-
tion, wire-saving can be easily made.
MOUNTING

●
In case of using screws
•
Mount using M4 pan head screws
with a tightening torque of 0.8N·m
or less. However, in case of side
mounting, make sure to mount the
unit such that the unit stopper faces
front.
Mounting position 1
●
Two installation positions are available for the unit mounting base so that
the unit direction can be changed. Install the base at one of them.
