Please thoroughly read the "For safe use" before using the SC-T4
properly.
Because these precautions are related to failure or malfunction,
observe the precautions for use without fail.
In order to use the SC-T4 properly,
observe the following precautions.
Precautions which are the cause of failure:
The SC-T4 is used exclusively to SS Checker (Detector).
Accordingly, do not connect other equipment.
●Precautions which are the cause of failure
●Precautions related to measurement
・Do not disassemble or modify the
Transmitter. Disassembly or
modification may cause fire or an
electric shock because there are high-
voltage parts inside the Transmitter.
・Turn off the Power immediately in the
unlikely event that there occur any
abnormalities such as smoke or
abnormal noise. Otherwise it may
cause fire or an electric shock.
[Be sure to read this instruction manual in order
to use the Transmitter SC-T4 properly.]

・Be sure to use the power supply of
100 to 240 VAC.
Otherwise it may cause fire or
electric shock.
・Do not wipe the Transmitter with
solvent. It may cause failure.
・To clean the Transmitter, first wipe
away lightly with a clean soft cloth
damped by diluted mild detergent
solution and then wipe off moisture
with a dry clean soft cloth.

the Transmitter.
Failure to observe
this precaution may
cause fire or an
electric shock. ・Do not give a strong shock to the
Transmitter.
・Do not press the CLEAN button, while
the SS Checker (Detector)is in the air.
・Make sure that the Cover is locked
without fail. Otherwise, protective
structure may not function adequately.
Keep the Power off during
installation and wiring operations.
Precautions which are the cause of failure:
" " denotes "Prohibited action", and " " denotes "Required action".
・Use Cable Clamps attached to the
transmitter for wiring. When the piping
are directly connected with the
transmitter, take a corrective action
such as caulking against intrusion of
gas because corrosive gas is in danger
of intruding through the piping, etc. into
the Transmitter. ・Do not bind the signal output cable with
the power cable or do not put them in
the one Cable Clamp.
・Install the transmitter
with attached
Mounting Bracket.
・Install the transmitter at a place
ventilating well and avoiding direct
sunlight.

The Alarm Level Indicator (Green) appears when the
measurements get higher than the Alarm Level.
When the measurements get higher than the Alarm Level continuously
beyond the time set by the Alarm Timer, the Alarm Relay Output will be
produced.
Although the measurements get
higher than the Alarm Level, since
higher period is shorter than that of
the Alarm Timer, Alarm Relay
Output will not be produced.
When the measurements
become lower than the
Alarm Level, the Alarm
Relay Output is released.
