2.0 Installation
2.1 Installation Considerations
Read the following information before installing,
wiring, and performing regular maintenance on the
equipment.
Do not install the detector:
• near trees and plants where falling leaves can block
the beam
• where intense sources of light and sunlight can
reflect directly into the receiver optics
A beam of light shining at a ±3-degree
angle of each receiver can cause false
alarms.
• on movable surfaces
• where subject to splashing water or sea spray
• beyond the maximum range of each model
• where strong electrical noise or radio frequency
interference occurs
• where strong vibration occurs
• in the presence of corrosive or explosive gas
Face upper and lower optical modules toward each
other on the transmitter and the receiver.
• Do not install or wire detectors during a
thunderstorm.
• Do not supply power until all wiring is
completed.
• Maintain power between 10.5 VDC and
28 VDC at all times.
• Do not disassemble or modify the base.
2.1.1 Beam Strength over Distance
The beam strength is best if used within the maximum
range of the detectors. If used for shorter distances,
excess beam energy reaches the receiver resulting in
reflection off nearby walls and incorrect
communication with other detectors.
2.1.2 Beam Spread
The beam spread is +0.7°. Refer to Figure 5 and Table 2
to determine the installation conditions.
