Do not install the unit where the detector is exposed to corrosive gas or dust, or a failure or shortened service life
may result.
The transmitter and receiver are in a set as the complete detector. Never use them separately or with other detec-
tors, or malfunction may result.
Do not install the unit where temperature or humidity rises extremely high, or the unit may get deformed or deterio-
rated and a failure may result.
Keep the unit away from magnets or any magnetized object, which may cause a failure or malfunction.
2. Observe following instructions for wiring and maintenance.
Do not disassemble or modify the unit, or a fire, electrical shock or failure may occur.
Do not perform wiring work with the power turned on, or a fire, electrical shock or failure may occur.
The required power (operation voltage range) is DC10.5V to 28V. Do not use the unit outside of the specified voltage
range, or a fire, electrical shock or failure may occur.
Do not perform wiring work when it thunders, or a fire, electrical shock or failure may occur depending on where
lightning strikes.
The movable range of the lens is 5° up and down respectively and 90° right and left respectively. Do not move the
lens beyond this range with force, or the unit may break.
Do not apply a strong impact or vibration to the unit, or a failure or damage may result.

GENERAL DESCRIPTION

The NR30TD/NR60TD/NR90TD outputs an alarm when the infrared pulse beam (referred to as beam hereinafter) emitted from
its transmitter is not received by the receiver for a certain period of time (beam interruption time). To reduce influences from
various external factors, the unit is provided with following features.
G 100 Times Sensitivity Allowance
As the transmitter emits beam 100 times as strong as the minimum level required for guarding, stable operation is maintained
even if beam energy is cut by rain, fog, frost, etc.
G Twin beam and guard method
To prevent an erroneous operation by detecting a small animal or bird, the unit is designed so that no alarm is output unless
both beams arranged in vertical two levels are interrupted at the same time.
G Double modulation detection method
This method uses the double (frequency and pulse) beam modulation so as to reduce influence from the external disturbance
light.
G Beam interruption time control
Using this function, it is possible to adjust the beam interruption time according to the installation site so as to reduce causal
factors of malfunction at that site.
