1 Introduction
1.1 Overview
The Barrier can be used together with a radar for access control in parking lots, and it primarily
consists of a top cover, casing, drive unit, control box, and barrier arm. The Barrier can be divided
into 2 categories depending on its arm position (right or left) when facing it.
Straight arm barrier and folding arm barriers are available.
Table 1-1 Barrier type
Type Description Remark
Straight arm barrier
●Barrier with 3 m (9.84 ft) straight arm with an
opening/closing time of 0.9 s.
●Barrier with 4 m (13.12 ft) straight arm with
an opening/closing time of 2 s.
●Barrier with 5 m (16.40 ft) straight arm with
an opening/closing time of 3 s.
●Barrier with 6 m (19.69 ft) straight arm with
an opening/closing time of 3 s.
Contact technical
support for specific
needs.
Folding arm barrier
●For barriers with 3 m (9.84 ft) arms, each of
the two sections of the arm is 1.5 m (4.92 ft),
and has an opening/closing speed of 0.9 s.
●For barriers with 4 m (13.12 ft) arms, the
main arm is 1.5 m (4.92 ft) and the sub arm is
2 m (6.56 ft). It has an opening/closing time
of 2 s.
1.2 Features
●With its AC variable frequency motor, drive unit and balance spring, the Barrier has highly stable
and reliable operations. Its motor and spring can sustain up to 5 million uses.
●The sheet metal casing makes it resistant to corrosion for up to 10 years.
●Designed with a buffer strip on its arm for enhanced safety. The buffer strip is made of
high-molecular-weight polyurethane (PU) which remains soft and not stiff in cold environments.
It has a lifespan for more than 10 years.
●Automatically rises when the barrier arm makes contact with an object.
●Barriers with 3 m (9.84 ft) or 4 m (13.12 ft) straight arms support the anti-collision function. A
turning gear is installed between the arm and the main shaft, allowing the arm to swing back
from a collision to avoid mechanical damage.
●The arm automatically rises at 90° in case of power failure. You can contact technical support to
customize the angle.
●Anti-drop function activates through its connection with the radar, loop, or IR sensor.
●12 VDC power adapter that is capable of supplying power to the connected radar.

●Supports remote control at a maximum distance of 50 m (164 ft) with no interference.

3 Installation
3.1 Installation Preparation
●This section introduces basic requirements for selecting and constructing the foundation. For
details on installing the Barrier, see the construction guide.
●The foundation must be constructed before the Barrier is installed.
Selecting Construction Site
The center of the foundation should be more than 300 mm (11.81'') away from the road side. The
barrier arm can open at a 90° angle vertical to the ground.

Foundation Construction Requirements

Table 3-1 Foundation description
No. Name
1 Foundation bolt
2 Foundation surface
3 PVC pipe
●Pour concrete to construct a foundation of 500 mm× 500 mm (19.69''× 19.69'') (L × W), and make
sure that the depth is between 150 mm–200 mm (5.91''–7.87''). Depths that do not fall within this
range will greatly influence the accuracy of radar detection.
●Use concrete of at least grade C15.
●Bury foundation bolts in the foundation. Make sure that the bolts are exposed 100 mm (3.94'')
above the foundation.
Figure 3-3 Foundation bolt (mm [inch])
●(Optional) If no foundation bolts are buried, you can use the expansion bolts provided in the
accessories of the Barrier.

◇After the concrete foundation hardens, drill 4 holes with a diameter of 16 mm (0.63'') to install
the Barrier.
◇Use M12 expansion bolts. Make sure that the thread length of the expansion bolt is longer
than 80 mm (3.15''), and its total length is more than 150 mm (5.91'').
◇The drilled holes and the installation position should meet the requirements shown in Figure
3-4 to facilitate installing the metal plates and fixing the Barrier.
Figure 3-4 Install expansion bolt (top view) (mm [inch])
●Thread the power cable and the signal cable separately through two 1-inch PVC pipes (buried in
the foundation) to the cable holes next to the foundation.
●After installation, make sure that when opening the Barrier, there are no obstacles within a 90°
vertical range.
3.2 Installing the Barrier
3.2.1 Installing the Casing
Prerequisites
●Read the manual carefully before installation. Refer to the barrier drawing attached to the casing
to know how the Barrier works and how to wire it.
●Check whether the power cable, signal cable, or internal wiring is loose or disconnected. If yes,
securely connect the cables before installation.
Procedure
Step 1 Unpack the packaging box.
Step 2 Place the casing on the foundation, and set the working direction of the arm vertical to the
vehicle movement direction (we recommend placing a layer of 3mm rubber under the
casing to reduce vibrations).
Step 3 Use the key to open the door, and then place metal plates on the foundation bolts.
Step 4 Adjust the horizontal and vertical positions of the casing, and then tighten the nuts with a
wrench.

Step 1 Align the arm with the mounting plate, and fix the mounting plate to the arm with M14 ×
140 hex head bolt.
Step 2 Push the arm to make it fit with the mounting plate completely.
Step 3 Install the control arm (right above the barrier arm) and then attach the plate.
3.2.3 Installing the Straight Arm
Different arm lengths require different installation methods.

Arms shorter than 4 m (included) are anti-smashing.
3.2.3.1 Installing the Anti-smashing Arm
Figure 3-6 Install the anti-smashing arm
Step 1 Connect the LED light bar that is fed through the arm to the cable that comes out of the
mounting plate.
The cable coming out of the mounting plate needs to be fixed to the plate surface with
fixing screws, in a way that allows the fixed cable to fit into the cable groove on the arm.
This will ensure the LED connector remains intact when the arm is attached to the
mounting plate.
Step 2 Place the arm in the mounting plate, and align the holes of the arm with those of the plate.
Step 3 Thread the M14 × 140 hex head bolt through the plate and the arm, and fix the bolt with
M14 nut, plain washer and spring washer.
Step 4 Push the arm to make it fit in the mounting plate completely.

Step 1 Thread four M10 × 75 bolts and plain washers through parts 1, 2, and 3.
Step 2 Fix the bolts with four M10 nuts and spring washers.
3.2.4 Opening the Top Cover
Step 1 Lift the arm up to its vertical state.
Step 2 Use your key to unlock the top cover, wait until the side of the cover near the arm is tilted,
and then push the cover forward to open it.

●ON: Enable automatic arm lifting during power failure.
●OFF: Disable automatic arm lifting during power failure.
2
Counting mode: Under this mode, when the Barrier is powered on,
and there is no anti-smashing signal triggered, the arm
automatically falls.
●2 and 3 are ON: Enable counting mode.
When the Barrier receives N signals (N ≤ 5) of opening,
including from camera and remote control, the arm will fall
after receiving N signals of vehicle passing, and the interval
between signals is longer than 1 second.
●OFF: Disable the counting mode.
3
●ON: Enable the function of auto-falling when vehicle passing.
●OFF: Disable the function of auto-falling when vehicle passing.
4
●ON: The Always on point of the anti-smashing vehicle
detector output is connected between the inverter VD port
and +24 V port (VD connects to NO and +24 V to COM).
●OFF: The Always off point of the anti-smashing vehicle
detector output is connected between the inverter VD port
and +24 V port (VD connects to NC and +24 V to COM).
When the vehicle detector detects vehicle passing, the inverter
keeps the arm lifted and lifts the arm that is falling, and the arm
falls after the vehicle passed.

3.3.2 Remote Matching Description
Figure 3-9 Receiver
●Match the remote information
◇Successful matching: Press and hold the learning button on the receiver for 2 s, press the
remote handle at least twice and then you can press keys on the remote to control the arm.
◇Failed matching: The remote handle is not pressed a while after pressing the learning button
on the receiver, and the receiver indicator does not flash 3 times immediately, but flashes 7
times after about 8 seconds.
●Clear the remote information: Press and hold the learning button on the receiver for more than 3
seconds, and then the remote cannot control the arm. This means the matching information has
