detector to factory default settings.
9 Ethernet port Connects to network with a network cable.
The distance in this section is the recommended distance. The actual installation distance
depends on the installation site conditions.
●Keep away from moving metal objects
Large moving metal objects should be kept 0.5 m to 2 m away from the detector to avoid false
alarms. Depending on the size of the metal object, the distance between the moving metal
object and the detector might vary.
●Keep away from radioactive electronic interference
The distance between the electronic interference source and the receiving coil should be as large
as possible. The recommended distance is 0.5 m to 4 m. However, the actual distance needs to be
based on specific circumstances. For example, you can go through a metal detector with a source
of interference until the best position is found. Interference can occur from electronic control
panels, radios and computers, image displays, high-power motors and transformers, AC wires,
transistor control circuits, flash fluorescent tubes, arc welding equipment, and more.
●Keep away from conductive electronic interference
Connect the power cord to a line that is not connected to other large loads, such as high-power
motors, because they can cause a large power or voltage shock in the line.
Installing Detector
Step 1 Open the packing box and take out the accessories.
Step 2 Loosen the 4 fixing screws with a crosshead screwdriver to separate the host box and the
beam.
Remove host box
Step 3 Attach the two ribbon cables to the host box.
Attach ribbon cables
Step 4 Feed the ribbon cables through the opening of the beam, thread them out from the two
sides, and then attach the host box back to the beam with the fixing screws.
Attach host box
Step 5 Connect the left ribbon cable to the left panel, and then use the wrench to attach the left
side of the beam to the left panel with two M8 × 60 screws. Connect the right ribbon cable
to the right panel, and then attach the right side of the beam to the right panel with two
M8 × 60 screws.
Attach panels
Step 6 Stand the detector up, connect the power supply, and then secure the power cord to avoid
accidental plug-off during use.
1) Attach the self-adhesive cable zip tie mount to one panel.
2) Connect the power supply.
3) Wind the power cord to the cable zip tie mount, and then feed the cable zip tie through
the mount to tie up the power cord.

Multiple Walk-through Site Installation
When installing multiple devices, space the devices at least 50 cm (d2), and also space the device
and X-ray security screening machine larger than 50 cm (d1). This recommended spacing can make
the little metal objects (such as coin) detected. If you install the devices with space smaller than 50
cm, there might be false alarm. If the spacing needs to be shortened because of limited installation
site, you need to adjust the frequency, lower the security level and sensitivity according to the actual
situation; otherwise, small metal objects might not be detected.
