Install the Mounting Bracket on the wall
and so forth. For mounting pitch, refer
to the Fig. to the right.
CAUTION:
If there is a projection on the mounting surface, separate
40 mm or more from the upper Mounting Holes of the
Mounting Bracket ( See Fig. to the right ) .

Fit the Mounting Bracket attached to the
Transmitter with the Fitting Screws.

Wiring
CAUTION:
Keep the Power off during wiring operations. Otherwise it may cause fire or an
electric shock.
Wire the Power Cable, at the end of wiring operation.
Make sure that the Circuit Breaker is normal ( OFF ) position ( Refer to [8]
Troubleshooting ) .
Controller Terminal Block
Compatible cable diameter with the Cable Clamps is 6
Use a shielded cable with nominal sectional area of 0.2
Detector Cable.
For extension of the Detector Cable, refer to [ 3 ] Detector Cable Extension. Use
a device such as a Pull-box if necessary.
Use a shielded cable with nominal sectional area of 0.75 to 1.25 mm
Signal Output Cable.
For connection to the Signal Output terminal, load resistance should be 300
Max ( including wiring resistance).
For connection to the Self Checking Relay Output terminal and Alarm Relay
Output terminal, load resistance should be 240 VAC and 1A Max.
Although a protective circuit is built in to prevent from overcurrent due to
thunderbolt, it is recommended to use fuses with rated current of 2A Max for the
purpose of improvement of safety.
Carry out grounding work.
Use a cross-linked polyethylene insulating vinyl sheath cable with nominal
sectional area of 0.75 to 1.25 mm
Reference:
When the Detector is in the air, analog ( 4-20mA ) signal output becomes
approximately 6mA,
