Care Instructions
Regularly check and clean the reader to ensure proper functioning. Avoid physical damage to the device.
Decommissioning
If decommissioning is required, follow the reverse steps of installation carefully.
Safety
- Read, observe and keep the instructions – the entire safety and operating instructions must be read and correctly followed before the readers are operated.
- Take all warnings into account – follow all warnings on the devices and in the operating instructions.
- Power sources – the readers should only be operated with the recommended power sources. If you are unsure whether you can use a specific power supply, contact your dealer.
Warning!
Health and Safety
Installation must be carried out in accordance with local fire, health and safety regulations. A secured door must be installed as part of an escape route and must have:
- a fail-safe lock. the door must be released in the event of power loss. Ideally, a solenoid lock should be used.
- an emergency switch with a glass cover for manual breaking the circuit, so that the fail-safe lock can be de-energized immediately in an emergency.
Notice!
Risk of damage to the equipment
Always switch off the power supply of the device before making changes to the installation. Do not connect or disconnect any plugs, data cables or screws while the power supply is switched on.
Notice!
Risk of damage

Functional requirements
- The LECTUS secure reader reads data from contactless RFID credentials and sends the data to a higher-level control center. This is where the evaluation takes place as to whether the credential is authorized or not.
- The result is sent back to the reader, which then provides a visual and an acoustic signal. Communication between the reader and the control center takes place through a Wiegand interface.
- The reader is available in four variants, mullion and compact design, with and without a keyboard.
- The reader has a tamper monitoring and tear-off detection. It consists of an internal floating contact. This contact must be evaluated separately through a controller input.
- The reader is suitable for both indoor and outdoor use.
Wiegand readers
The following readers support Wiegand protocol.
| Commercial Type Number (CTN) | Description |
| ARD-SIGR20-ICL | Card reader, R20, iCLASS, Wiegand |
| ARD-SIGR20K-ICL | Card reader w/ kp, R20, iCLASS, Wiegand |
| ARD-SIGR40-ICL | Card reader, R40, iCLASS, Wiegand |
| ARD-SIGR40K-ICL | Card reader w/ kp, R40, iCLASS, Wiegand |
| ARD-SIGR20-SEO | Card reader, R20, SEOS, Wiegand |
Data security of Wiegand interface
- Wiegand is a popular type of communication interface for door access systems, but it lacks IT security protection. Data transmission is not secure because the interface is not encrypted.
- The communication cable and the area between the connected devices should be physically protected from access by unauthorized people to avoid unauthorized data. The cable should also be routed in the secured area.
- The tamper detection feature of the reader should be used.
- Data protection note: The card reader sends personal data (card number) over the unsecure interface to the access management system. Check in advance if this is compliant with your data protection regulations.
RFID technology
The LECTUS secure readers support by default the following technologies:
- iCLASS (26 bit and 37 bit)
- iCLASS SE (26 bit and 37 bit)
- Seos (26 bit and 37 bit)
The RFID technology that will be used is dependent on the reader model. Check this in advance.
Reading distances
The normal reading distance depends on the respective reading system, the installation environment, and the type of data carrier. Direct mounting on metal might reduce the optimal reading distance.

Table 2.1: Maximum reading distances of the different credentials for the LECTUS secure readers
Notice!
- The reading distances listed above are distance ranges measured on the basis of a selection of transponder media. These measured reading distances are to be regarded as typical guide values.
- If other transponder media are used (chip type, design, size, production process), the distance ranges may differ and it is recommended to carry out a suitability and functional test of the respective medium before using or planning to use the reader.
Influencing (reducing) the reading distance
The reading distance can be influenced due to different reasons. On the one hand this is influenced by the medium (i.e. the data carrier) and on the other hand by the ambient conditions of the antenna and the data carrier.
The following is a list of points that can reduce the reading distance:
- “Shade” or shield the data carrier with metal, such as EC card in your wallet, key fob on your key ring, etc.
- No optimal coupling, i.e., the antenna surface of the data carrier is perpendicular (90 °) to the antenna surface of the reader
- Data carrier itself
- key fob (small active antenna surface)
- “bad” response from the data carrier (ID card / key fob)
- combination ID card (e.g. LEGIC® / inductive, MIFARE / inductive etc.)
- Metal in the “active” effective area of the HF field. The transmission energy is attenuated. This point is particularly relevant when installing the reader components in metal front panels (including metal columns, etc.).
Installation
Choosing the installation location
Notice!
When choosing the installation location, note that the readers can interfere with each other or be negatively influenced by other systems and sources of interference. The readers can still disturb each other at a distance of about two to three times the reading distance. High-energy sources of interference in the range of the modulation and carrier frequencies can also interfere with the transmission.
Installing data and supply lines
- When supplying the reader (especially over longer distances), ensure that the cable cross-section is adequate. Since the power consumption of the individual systems is partially pulsed, short-term voltage drops cannot be detected with a conventional multimeter (digital or analog). However, these voltage drops can cause a “POWER-ON-RESET” on the reader component, which can lead to communication problems.
- When dimensioning the power supply and the cable cross-sections of the cabling, the maximum current consumption must be taken into account. It is essential to ensure that the input voltage remains constant and corresponds to the technical specifications of the reader.
Assembly preparation
- Lay the connection cables according to the local conditions and prepare them for connection.
- Remove the two 5-pin plug-in terminal from the reader module and connect the wires according to the Wiring diagram.

Notice!
The wiring must be carried out in a de-energized state. In other words, the operating voltage may only be switched on after the reader has been fully installed!
Assembling the reader
Notice!
Install the reader on a flat, stable surface. Failure to do so may compromise the IP rating and/or tamper feature.
Notice!
When mounting on or near metal, use a wall mount box to ensure an optimal read performance.
Notice!
Use the supplied screws to ensure the correct fitting and to avoid damaging the reader or the mounting plate.
To mount the reader:
- Determine an appropriate mounting position for the reader.
- Unscrew the top cover. The screw is located at the bottom of the reader.
- Use the supplied appropriate screws and drill the holes to mount the plate.
- Plug in the terminals that were prepared in Assembly preparation, page 9.
- Hook the upper part of the reader on the top of the mounting plate. Push the bottom of the reader to the wall until it is inside the mounting plate.
- Drill back the screw in the bottom of the reader to secure it to the mounting plate.
To test if the reader is working properly:- Power the reader. The reader beeps and the LED flashes.
- Present a credential in front of the reader. The reader beeps and the LED flashes.
Care instructions
- Do not operate the reader with sharp objects, such as rings, fingernails and keys.
- For cleaning, do not use any corrosive or plastic-corrosive liquids such as gasoline, turpentine, and nitrous solution. Harsh detergents can damage or discolor the surface.
- Do not use cleaning agents with mechanical effects, such as scouring milk and scouring sponge.
- Only clean the reader with a soft, damp cloth and only use clear water.
Decomissioning
Old electrical and electronic equipment
This product and/or battery must be disposed of separately from household waste. Dispose such equipment according to local laws and regulations, to allow their reuse and/or recycling. This will help in conserving resources, and in protecting human health and the environment.
