FOR PROPER INSTALLATION
1. Observe following instructions for installation of the unit.
CAUTION
This detector is intended for detection of human intruder. When using it for any other purpose, be sure to study and
test carefully in advance.
Study carefully possible intrusion route and posture of an intruder to determine the installation position so that the
beam is interrupted without fail.
Where there is not enough strength, perform full reinforcement work before installing the detector. If installed where
not strong enough, the detector may drop, possibly resulting in its failure or damage and personal injury.
The beam spread angle of this detector is about 1
°
on each side. When using a multiple number of the same type
detectors or when using this detector with another type detector, position them so that no interference would occur.
Do not install the unit where the beam is interrupted by an obstacle, or malfunction may result.
Do not install the unit where intense source of light such as sunlight and automobile head light beam is reflected into
the receiver. A strong light incoming within
±
3
°
angle of each receiver axis may cause malfunction.
Do not install the unit where the detector can move easily after being installed, or malfunction may result.
Do not install the unit where it is exposed to foul water or sea spray, or a failure or malfunction may result.
Do not install the unit where the distance between the transmitter and receiver exceeds the rated detectable dis-
tance, or malfunction may result.
Do not install the unit where electrical noise or electromagnetic wave exists, or a failure or malfunction may result.
Do not install the unit where the detector receives strong impact or vibration, or a failure or malfunction may result.
