PHOTO EYE INSTALLATION
For UL 325 compliance, all external
entrapment protecon sensors
must have N.C. sensor outputs for
monitoring and powering purposes.
Wire Gauge and Type:
18AWG 2C Through-beam Photo Eye Transmier, Shielded
18AWG 4C Through-beam Photo Eye Receiver, Shielded
When unpacking photo eyes, DO NOT DISPOSE OF
THE RECEIVER SUNSHIELDS (“alignment cones”). The
sunshields are eecve at reducing the eects of solar
interference or crosstalk.
Mount photo eye receivers to columns with the shields
intact and adjust as required. If two sets of photo eyes are
being installed on one column and crosstalk is occurring,
remounng photo eyes in the following conguraon
may eliminate this issue:
• Install the transmier above the receiver on one
column.
• Install the receiver above the transmier on the
opposing column.
• Angle the top device upward and boom device
downward to avoid crosstalk.
1. Remove cover from photo eye by removing the 4 corner screws. The cover should not be placed on
photo eye unl the photo eye transmier and receiver are aligned.
2. Figure 15 shows the wiring and DIP switch sengs of an EMX-MON photo eye (typical through-beam
wiring), the type of photo eye normally shipped with a SpeedGate by Wallace Perimeter Security.
