During installation and repair of the device, the ESD protective measures must be
considered.
Please consider the following guidelines before the installation or maintenance of
the device:
• Always carry an ESD antistatic wristband when dealing with electronic
components. Connect one part of the wristband with a discharge socket or
an unvarnished grounded metal component. This way, static charges are
discharged from your body securely and effectively.
• Only touch the printed circuit boards at the edges. Do not touch the printed
circuit board itself or the connector.
• Place all dismantled components on an anti-static surface or in an anti-static
container.
• Avoid contact between printed circuit boards and your clothing. The
wristband only protects the printed circuit boards against electrostatic
discharge from the body, but there is still a risk of damage through
electrostatic discharge from your clothing.
• Only transport and dispatch dismantled modules in protective bags.

4.3 Hardware equipment
4.3.1 LED
For optical user guidance, the subterminal is equipped with a two-color LED (red
and green).
The LED is directly activated by B-Net 91 04 depending on the operating mode or
by corresponding commands from the control unit.
4.3.2 Acoustic signal generato r
The subterminal has a beeper for acoustically signalizing certain states. The
beeper is directly activated by B-Net 91 04 depending on the operating mode or by
corresponding commands from the control unit.
4.3.3 Digital outputs
The B-Net 91 04 has one relay. The name of the relay is R1.
In stand-alone mode, this relay is used for the door opener.
In online operation, the relay may be activated by the corresponding commands
from the access control unit, e.g. door opening in secured areas.
In online operation, the device works as subterminal of an access control.
The device can be connected to access control units of the device families Bedas,
Bedanet and B-Net, such as B-Net 92 50, Bedanet 92 90, or a time recording
terminal of the B-Net series.
One or several subterminals are connected to the control unit by means of the
RS-485 subpartyline. The subterminal is operated in the polling mode. The control
unit polls the connected subterminals one after the other in order to send or receive
data.
If a badge is presented, the badge data is sent to the control unit. The control unit
decides whether a badge is authorized or not and sends the respective commands
for LED, beeper and relay back to the subterminal. The internal relay should only be
used in secure areas for opening a door. Therefore, the control unit generally
controls and opens the door.
Remark
On delivery, online operation is preset in the subterminal.
4.4.2 Stand-alone operation
NOTICE!
Stand-alone operation may only be used together with LEGIC® prime media (media
with existing data structure).
In stand-alone operation, the device works independently without connected
control unit. A customer number list stored in the device allows for the verification
check of every booking. LED, beeper and relay are activated accordingly.
A service PC and a parameter setting tool are required for set-up. The customer
number list is transmitted via the RS-485 subpartyline. After activating the standalone operation, the service PC is removed again.
A customer number list can contain up to 5 entries. One individual entry may be a
customer number or a complete badge number. If, for examples, the authorization
is given to all employees of a company, the customer number must be stored. If
the authorization is given to individual employees, the complete badge number
(customer number + ID) must be stored.
The green LED is lighted during operation. When a badge is presented, the badge
data is read and checked. If the verification is positive, the relay is activated for 3
seconds (default). A successful booking is confirmed by means of a 1-second
acoustic signal. After an invalid booking, the red LED and the beeper are activated
alternately for 3 seconds.
An accurate installation of all components is a basic requirement for proper
functioning. The following installation instructions must be adhered to.
The device can be mounted either directly on the wall or on a door frame.
For cable outlet, a drilling of approx. 10 mm diameter is required. An edge which
might be produced must be trimmed.
A screw guide is positioned in the middle of the housing’s top and bottom. Use only
the screws included in the delivery for fastening the device.
The following connectors must be prearranged at the installation site of the device.
• Power supply
• Data line for access control unit (online operation only)
• Cables to the door opener (if required)
The terminal must

To steel parts, a distance of 10 cm must be observed on all sides. If this distance is
not observed, the reading quality is impaired. Then, the maximum reading distance
is not achieved. Problems may appear with different LEGIC® media.
The terminals frame included in the delivery must be used for mounting the device
on metal surfaces.
The terminal frame increases the distance between reader and metal surface thus
reducing damping by the metal.
5.3 Installation Lines
(A) Data line to subterminal
The subterminals are connected to the control unit via a 2-wire subpartyline. It can
be designed in star-shape or as partyline.
NOTICE!
The shielding of the data line is generally connected on both sides.
The complete bus connection (master lines and branch lines) may be up to 2,000
meters long. One branch line may not exceed 100 m.
For short distances (up to 20 meters max.), it is permitted to have the operating
voltage for the subterminal and the data line in one single cable. In this case, the
subterminal is grounded via the shield of the data line.
For line lengths over 20 m, a separate power supply cable (C) must be provided for
the subterminal.
Line requirements:
Shielded line with twisted wire pairs,
cable diameter 0.4 mm to 0.6 mm
for instance standard telephone cable J-Y (St) Y 2 x 2 x 0.6 mm.
Recommended cable:
CAT.5 S-UTP 4 x 2 AWG 24 or AWG 22 (according to EIA/TIA568).
(B) Line to the door opener
Line requirements:
Cables with a cable diameter from 0.5 mm to 0.8 mm can be used.
Recommended cable:
CAT.5 S-UTP 4 x 2 AWG 24 or AWG 22 (according to EIA/TIA568) or higher.
(C) Power supply and grounding
In online operation, power is supplied by the superior control unit and can be tapped
easily from there.
If the device is used without control unit or if power cannot be supplied by the
control unit, a separate supply unit, e.g. SV 100, SV 900, SV 905, must be used.
In case of long lines, the voltage drop - caused by the line resistance - must be
considered.
The ground wire must be led from the power supply to the terminal.
Cables with a cable diameter from 0.5 mm to 0.8 mm can be used.
Three wires are required for power supply + ground (SV 100 / SV 900).
If door-opener voltage is required, two further wires are needed (SV905).
