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.

etc.

There are high 

voltage parts inside 
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.

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.

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 

i

n the 

unlikely event that there occur any 
abnormalities such as smoke or 
abnormal noise. Otherwise it may 
cause fire or an electric shock.

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.

[Be sure to read this instruction manual in order 
to use the Transmitter SC-T4 properly.]
