1. Important Security Instructions
1.2 Installation Cautions
1. All wires must run through casing pipes, for example PVC or galvanized pipes, to prevent
failure caused by rodent damage. Although a control panel is designed with good
antistatic, lightning-proof, and leakage-proof functions, ensure its chassis and the
AC ground wire are connected properly and the AC ground wire is grounded
physically.
2. It is recommended not to plug/unplug connection terminals frequently when the
system is energized. Be sure to unplug the connection terminals before starting any
relevant welding job.
3. Do not detach or replace any control panel chip without permission, because
unprofessional operation may cause damage to the control panel.
4. It is recommended not to connect any other auxiliary devices without permission.
Before all non-routine operations, must communicate with our engineers in advance.
5. A control panel should not share one power supply with any other large-current
device.
6. It is preferable to install card readers and buttons at heights of 1.4-1.5m above the
ground, but the heights can be adjusted according to customers’ usual practice.
7. It is advised to install control panels at places easy of maintenance, like a weak
electric well.
8. It is strongly recommended that the exposed part of any connection terminal
should not be longer than 4mm, to avoid short-circuit or communication failure
resulting from accidental contact with excessive exposed wires.
9. To save access control event records, download data periodically from control
panels.
10. Get prepared according to application situations for unexpected power failure,
like connecting power supply with UPS.

11. In inBIO reader connection, if the reader shares the power with the control panel,
it is recommended that the wire should be less than 100 meters. If you need to use
in the longer distance, please use the separate power supply.
12. The connection between a PC and a control panel should be shorter than 1200m
for RS485 communications. A length within 600m is recommended to make
communications more stable.
13. To protect the access control system against the self-induced electromotive force
generated by an electronic lock at the instant of switching off/on, it is necessary to
connect a diode in parallel (please use the FR107 delivered with the system) with
the electronic lock to release the self-induced electromotive force.
14. It is recommended that an electronic lock and a control panel should use
respective power supplies.
15. It is recommended to use the power supply delivered with the system as the
control panel power supply.
16. In a place with strong magnetic interference, galvanized steel pipes or shielded
cables are recommended, and proper grounding is required.

e-way or two-door two-way access is applicable to the inBIO260
system.
The access control management system consists of two parts: Management
workstation (PC) and control panel. They communicate via TCP/IP or RS485
networks. On a 485 bus, each management workstation can be connected with up to
63 inBIO control panels (preferably fewer than 32). The communication wires
should be kept away from high-voltage wires as far as possible, and should be
neither routed in parallel with nor bundled with power wires.
A management workstation is actually a PC connected to the network. By running
the access control management software installed in the PC, access control
management personnel can remotely perform various management functions, like
adding/deleting a user, viewing event records, opening/closing doors, and
monitoring status of each door in real time.

3.5 Connection with External Accessories
1. Door sensor
A door sensor is used to detect the open/closed status of a door. With a door sensor
switch, an access control panel can detect illegal opening of a door, and will trigger
an alarm. Moreover, if a door is not closed within a specified period of time after it
is opened, the door control panel will also prompt an alarm. It is recommended to
select two-core wires over 0.22 mm
2
. A door sensor may be omitted if it is unnecessary to
monitor online the open/closed status of a door, trigger an alarm when the door is not
closed for a long time or there is illegal access, and use the interlock function.
2. Exit button
An exit button is a switch installed indoors to open a door. When you press the
button, the door will be opened. An exit button is fixed at a height of about 1.4
meter above the ground. Ensure it is located in the right position without slant, and
its connection is correct and secure (Cut off the exposed end of any unused wire
and wrap it with insulating tape). Note to prevent the electromagnetic interference
(such as light switches and computers). It is recommended to use two-core wires over
16
0.3mm
2
as the connection wire between an exit button and a control panel.
3. A ux ili ary in put
inBIO160 provides one auxiliary input interface; inBIO260 provides two,
and inBIO460 provides four, which are connected to infrared body
detectors, smoke detectors, gas detectors, window sensor alarms, wireless exit
buttons, etc. Auxiliary inputs are set through relevant access control software.
For details, please refer to Access5.0 User Manual.

Note: The diagram above takes inBIO460 for example. By contrast,
inBIO160 provides one auxiliary input interface; inBIO260 provides two, and
inBIO460 provides four.
3.6 Connection with Readers
The control panel supports inBIO biometric verification reader and Wiegand reader.
17
In use of inBIO reader, all operations including storage, verification, etc. execute in
control panel. No need to re-register the fingerprints for reader changing. Realize
the real biometric reader connection.
1. Connected with inBIO readers
inBIO160 can connect two inBIO readers in the one-door two-way mode.
inBIO260 provides four readers, which can be connected in the two-door two-way
mode. inBIO460 provides eight readers, which can be connected in the two-door
two-way or four-door one-way mode.
485 reader connection: First of all, set the 485 address (device number) of reader by
software, DIP switch or keypad method. Such as the reader 1, 2 (the odd number is
for enter reader, and the even number is for exit reader), for example, the 485
address is 1, 2, and the door number is 1. For more information, please refer to the
software user manual.
Note: In inBIO reader connection, if the reader shares the power with the
control panel, it is recommended that the wire should be less than 100 meters.
If you need to use in the longer distance, please use the separate power supply.

inBIO260 provides four readers, which can be connected in the two-door two-way
mode. inBIO460 provides four readers, which can be connected in the two-door
two-way or four-door one-way mode.
The Wiegand interfaces provided by the inBIO series can be connected to different
types of readers. If your card reader does not use the voltage of DC 12V, an external
power supply is needed. A reader should be installed at a height of about 1.4 meter
above the ground and at a distance of 30-50mm away from a door frame.

3.7 Relay Output Connection
Note: The factory default jumping is set as dry mode.
3) Considering of the consumption of the control panel, the Wiegand reader and the
inBIO reader, the standard power supply is 12V/3A. So we don’t recommend the
lock and the control panel use the common power supply. If it is necessary to use,
20
inBIO160 has two relays (by default, one used as a control lock and the other
used as an auxiliary output); inBIO260 has four relays (by default, two used as
control locks and the other two used as auxiliary outputs); inBIO460 has eight
relays (by default, four used as control locks and the other four used as auxiliary
outputs).
The relays for auxiliary outputs may be connected to monitors, alarms, door
bells, etc. Auxiliary outputs are set through relevant access control software. For
details, please refer to Access5.0 User Manual.
A lock relay can be connected in the dry and wet modes, while an auxiliary
output relay cannot. The following illustrates relay output connection with an
example of door connection.
1) An access control panel provides multiple electronic lock outputs. The COM and
NO terminals are applicable to the locks that are unlocked when power is connected
and locked when power is disconnected (that is NO lock). The COM
and NC terminals are applicable to the locks that are locked when power is
connected and unlocked when power is disconnected (that is NC lock).
2) The control panel supports “dry mode” and “wet mode” by using the jumper. For
“wet mode”, short 2-3 and 4-5 terminals. The control panel and the lock use
the separate power supply. One is connected with +12V and GND of POWER
interface (for the control panel), the other is connected with V+ and V- of
LOCK interface (for the lock)..
Dry mode jumper setting: Short 1-2 and 3-4, and the device power supply will be
used for the relay output.
Installation Guide for inBIO460 Series Control Panel
3. Connection and Installation
we suggest changing the bigger one, such as 12V/5A. Except the power
consumption reserved, there are 2A current for the lock. For the common electrical
lock (the standby current is 300mA, the max current is 500mA), the max connected
lock is 4.
4) To protect the access control system against the self-induced electromotive force
generated by an electronic lock at the instant of switching off/on, it is necessary to
connect a diode in parallel (please use the FR107 delivered with the system) with
the electronic lock to release the self-induced electromotive force.

3.8 System Power Supply Structure
An access control operator panel is powered by +12V DC. Generally, to reduce
25
26
power interference between control panels, each control panel should be powered
separately. When high reliability is required, control panels and electronic locks
should be powered respectively.
To prevent power failure of a control panel from making the whole system unable
to work normally, the access control management system is usually required to have
one UPS at least, and access control locks are powered externally to guarantee the
access control management system can still work normally during power failure.
Installation Guide for inBIO460 Series Control Panel
4. System Networking
4. System Networking
4.1 System Wiring and Wires Requirements
1. RS485 communication wires are made of internationally accepted shielded
twisted pairs, which provide effective protection and shield of interference.
2. The power supply is 12V DC converted from 220V.
3. The Wiegand readers use 6-core communication shielded wires (RVVP 6×0.5mm)
(usually there are 6, 8, and 10-core types available for users to select) to reduce
interference during transmission.
4. As an electronic lock has a big current, it generates strong interference signal
during an action. To reduce the effect of an electronic lock during an action on other
elements, 4-core wires (RVV 4×0.75mm
2
, two for a power supply and two for door
sensor) are recommended.
5. For EXT485 communication, we suggest to use 4-conducotor wire (RVVP
4*0.5mm)
6. Other control cables (like exit buttons) are all made of 2-core wires (RVV
2×0.5mm
2
).
7. Notes for wiring:
Signal wires (like network cables and RS-485 wires) can neither run in parallel
with nor share one casing pipe with large-power electric wires (like electronic
lock wires and power cables). If parallel wiring is unavoidable for
environmental reasons, the distance must be over 50cm.
Try to avoid using any wire with a connector during wiring. When a connector
is indispensable, it must be crimped or welded. No mechanical force can be
applied to the joint or branch of conductors.
27
In a build
ing, distribution lines must be installed horizontally or vertically.
They should be protected in casing pipes (like plastic or iron water pipes, to be
selected according to the technical requirements of indoor distribution). Metal
hoses are applicable to ceiling wiring, but must be secure and good-looking.
Shielding measures and shielding connection: If the electromagnetic
interference in the wring environment is found strong in the survey before
construction, it is necessary to consider shielding protection for data cables
when designing a construction scheme. Overall shielding protection is required
if there is a large radioactive interference source or wiring has to be parallel
with a large-current power supply on the construction site. Generally, shielding
measures include: Keeping a maximum distance from any interference source,
and using metal wiring troughs or galvanized metal water pipes to ensure
reliable grounding of the connection between the shielding layers of data
cables and the metal troughs or pipes. Note that a shielding enclosure can have
a shielding effect only when it is grounded reliably.
Ground wire connection method: Reliable large-diameter ground wires in
compliance with applicable national standards are needed on the wiring site,
and should be connected in a tree form to avoid DC loop. These ground wires
must be kept far away from lightning fields. No lightning conductor can serve
as a ground wire, and ensure there is no lightning current through any ground
wire when there is lightning. Metal wiring troughs and pipes must be
connected continuously and reliably, and linked to ground wires through
large-diameter wires. The impedance of this section of wire cannot exceed
2ohm. The shielding layer also must be connected reliably, and grounded at
one end to guarantee uniform current direction. The ground wire of the
shielding layer must be connected through a larger wire (not smaller than
2.5mm
2
).

4. System Networking
4.2 TCP/IP Network Communication
The Ethernet 10/100Base-T Crossover Cable, a type of crossover network cable, is
mainly used for cascade hubs and switches, or used to connect two Ethernet
end-points directly (without a hub). Both 10Base-T and 100Base-T are supported.
TCP/IP Communication System Networking
4.3 RS485 Network Communication
1. RS485 communication wires are made of internationally accepted RVVP
wires (shielded twisted pairs), which prove effective to prevent and shield
interference. RS485 communication wires should be connected by means of
bus cascade instead of in a star form, to achieve a better shielding effect by
reducing signal reflection during communications.
2. A single 485 bus can be connected with 63 access control operator panels at
most, but preferably should be connected with less than 32.
3. To eliminate signal attenuation in communication cables and suppress
interference, if the bus is longer than 300 meters, one 120ohm resistance is
usually inserted between the first and last access control operator panels on the
RS485 bus.
29
4. In inBIO
reader connection, if the reader shares the power with the control
panel, it is recommended that the wire should be less than 100 meters. If you
need to use in the longer distance, please use the separate power supply.
5. For this access control operator panel, putting place 8 of the DIP switch to the
ON position is equivalent to parallel connection of one 120ohm resistance
between the 485+ and 485- lines.
As shown in the figure below, put number 8 of the DIP switches of the first and last
control panels to ON position.

2. Restoring factory setting
The silk-screened 7 (number 7) of the DIP switch is the switch for restoration of
system settings. The switch is set to OFF by default. When it is moved upwards and
downwards for three times within 10 seconds and finally returned to OFF position,
the factory settings will be restored after the access control panel is restarted.
3. Terminal resistance setting
Number 8 is for setting the RS485 termination resistance. Putting the switch to ON
position is equivalent to parallel connection of a 120ohm termination resistance
