AXON Reader EV3 connects the card to the access control system over CAN. An onboard antenna, audible and visual feedback, and a local contact bring the interaction to the entrance, door or elevator panel.
For the user, access starts at the reader. Within the installation, this point brings together the card, audible and visual feedback, and communication with the master.
Place the reader near the entrance used by residents and staff every day. The card profile and permissions are defined in the system configuration.
The reader obtains the card identity, while the master and nodes connect permissions to floor signals. Position and enclosure are planned around the panel.
Offices, storage rooms and technical areas may be assigned to different user groups. The reader brings card identification close to each entrance.
At a building entrance or elevator panel, users need a clear interaction: present a card and receive a response. AXON Reader EV3 is the RFID/NFC reader in the AXON family for that interaction, with its antenna, reader electronics and CAN connection on one board.
The reader works as part of the access control installation. It obtains the card identity; the master coordinates control, while local contacts or output nodes interface with the equipment. This division of roles is useful in buildings with several entrances, floors and areas with different permissions.
The buzzer and LED indicators provide audible and visual feedback at the reader. A local SSR contact, tamper input and service interfaces support integration into an enclosure. Cards, mounting and communication settings are selected together so the reading point suits everyday use.
The same reader can serve a landing, building entrance, door, garage or barrier access point. It communicates with a master located inside or outside the elevator cabin, alongside compatible relay nodes on the same CAN lines. Each master supports up to 240 addressed readers and nodes and stores up to 1,000,000 cards; those capacities belong to the master-managed system.
Reading, authorisation and control are separate steps. Their configuration determines what happens when someone presents a card.
The user holds a card near the reading area. The antenna and RFID/NFC electronics interact with the selected card profile. The reader should be visible and within easy reach of the people using the entrance.
Reader EV3 has an integrated antenna for card interaction. Cards are selected to match the profile supported by the configuration, including the identification method and information required for the access request.
Reading a card and authorising entry are separate steps. The system links the credential to a user and their permitted access points: a building entrance, floor, door or service area.
The master has the central role in the AXON architecture. The reader communicates over CAN; access rules and information exchange are defined by the firmware and system configuration. The reader provides the physical identification point.
Once the request is processed, a suitable contact interfaces with the equipment’s control input. The contact may be at the master, on an output node or, depending on the configuration, on the reader itself.
For an elevator, the panel signals are reviewed. For a door or garage, the relevant controller interface is assessed. Selection covers the complete access path, from the card to the control signal.
Reader placement follows the way people move through a building. One property may have several identification points, each serving different users and mounting conditions.
Inside the cabin, the reader can sit beside the panel used by passengers. Identification is linked to floor permissions, while the master and assigned outputs interface with panel signals. Passengers have a clear place to present their card.
Available panel space, the material in front of the antenna and the cable route are considered together. The access system controls permission to request floors; elevator movement, braking and safety functions remain with the elevator equipment.
At a shared entrance, the reading point should be easy to recognise. Residents, staff and service providers can present cards according to the building’s rules, with audible and visual feedback configured for that point.
The reader is mounted in an enclosure suited to its location. Accessibility, lighting, the mounting surface and physical cable protection are considered for the way the entrance will be used.
An office, storage area or technical room may require different permissions from the main entrance. Positioning the reader beside the door connects the card interaction to that specific access point and makes the separation of areas clear.
The installer defines the interface to the door controller, lock power supply and exit arrangements. The reader provides identification, while the other equipment provides control and the functions required by the door. Administration responsibilities are set for the user group.
Reader EV3 can provide card identification in a garage access configuration when the user presents a card close to the reader. Its position is chosen around the entrance layout, stopping space and automation interface.
Planning covers the enclosure, power supply and system connection. The command reaches a suitable input on the gate or barrier controller; the motor and sensors remain part of the automation. Position the reader so users can comfortably present their cards.
Card compatibility and antenna placement directly affect the user interaction. Both are selected for the specific Reader EV3 configuration.
If the building already uses cards, gather their specifications and how they are used. For a new installation, choose the card profile alongside user management, enrolment and access rules.
RFID/NFC describes the reading interface. Compatibility requires the card, firmware and configuration to support the same profile. An NFC-equipped phone is not automatically a supported access credential.
The antenna is built into the reader board, so nearby materials and components are considered when choosing the enclosure. Metal panels, screws and cable placement can affect the conditions for card interaction.
The mounting plan defines the board orientation and the surface where users present a card. Antenna configuration and checks with the final enclosure help determine the position. Reading range depends on this combination and the card used.
People should be able to see where to present a card without needing repeated instructions. Plan the reading-area marking, enclosure orientation and indicator visibility together, especially when fitting the reader inside an existing panel.
At entrances used by many people, define what the light and sound responses mean. Clear, consistent explanations help residents and staff distinguish card presentation from the outcome of the access request.
CAN communication connects the identification point to the AXON architecture. The master and nodes are selected to match the interfaces and protocol of the configuration.
Both Reader EV3 connections use the same CAN lines. CAN OUT continues the cabling where the installation topology requires it; it does not provide a second independent channel or a backup communication path.
Reader EV3 uses Classic CAN. The bus plan defines the devices, cable route and termination at the relevant ends. Reader count is determined by the protocol, cabling and power supply, together with the other nodes on the same bus.
The card-reading point may be some distance from the control cabinet. CAN lets the reader sit close to users while the master remains the central controller. Interface and firmware compatibility are established for the chosen combination.
Master Lite has one CAN bus; Master Premium has two isolated CAN channels. The choice depends on the building layout, power supply and required connections. The reader remains the identification point in the selected configuration.
A master outside the cabin can serve this reader at the landing and relay nodes inside the cabin through the same compatible lines. The layout follows the available wiring and avoids requiring a different controller type for each location.
A reader provides an identification point, while the installation may require several control signals. In the modular architecture, output nodes provide those contacts near the panel or equipment receiving the command.
AXON Node8 offers eight SSR contacts for electronic button signals. The number of nodes follows the actual access points and interfaces. Reader, contact and door counts are separate considerations in the system plan.
Light, sound and the output interface form part of the access point. Their behaviour is configured around the way the system will be used.
An indicator near the card area helps users follow the interaction. Reader EV3 includes LEDs for this purpose. They should be clearly visible through the enclosure, with their meaning defined in the configuration.
Colour or illumination patterns can be used according to the functions implemented in the firmware. The reader indicator represents a state assigned by the system; it is not itself a sensor confirming that a door has physically opened or equipment has moved.
Sound can complement the light when a user is looking at the card or panel. The onboard buzzer provides this option. The sound and its timing are configured for the interaction and should be distinguishable at the point of use.
At an entrance or inside a cabin, sound is considered alongside the surroundings and enclosure. The signal should have a clear meaning for residents and the service team, according to its configured function.
The board includes one local SSR contact. It provides an electronic interface to a suitable equipment input when the configuration calls for control close to the reader. Electrical requirements and use are determined by the external signal.
The contact does not supply power to a lock or motor. Power equipment has its own interface and protection, with the reader signal integrated into that arrangement. The installer documents the contact connection and the equipment receiving the command.
A reading point depends on both the device and its installation. Reader EV3 includes electrical protection and functions that are complemented by the enclosure and system configuration.
The local power input includes protection against reverse polarity and transient pulses, while the CAN interface has electrostatic discharge protection. These measures apply at the points where the reader connects to the installation cabling.
Plan the power source, return path and cable route alongside the devices on the bus. The enclosure and mounting complete the protection of the electronics according to the surroundings and how the access point is used.
The tamper input allows an enclosure mechanism to report its state. The connection is planned around the housing and mounting method, for example where the installation needs to detect a cover being opened.
Signal processing, logging and notifications are defined by the system and platform configuration. The required response is specified for the way the reader is used in the building.
Reader EV3 includes support for device identity and cryptographic functions according to the configuration. These relate to how the reader is integrated and communicates in the selected system.
User access is defined through the card profile, authentication method and permissions for each entrance. Managing these choices is part of the complete solution, together with the master and platform.
The reader provides the point of identification. The master and platform manage who may use it, when, and which access point receives the command.
Administrators assign cards to selected entrances, floors, doors, garages and barriers, with schedules and validity periods. Payment-linked access can be configured for specific points; when validity or the payment deadline expires, access is blocked at the points the administrator selected.
Residents receive advance notice on their phones. Reader EV3 identifies the card; the platform manages payments and the master applies the rule. At an emergency exit, restrictions apply to entry only, while escape and emergency release remain free.
Card and permission changes are distributed across connected masters in real time. An administrator can deactivate a selected reader remotely, without deactivating every reader in the building. A remote change requires the master and reader to be connected.
Reader-to-master communication is encrypted, as are the master’s cloud links. Local diagnostics reached through the master help the installer inspect the reading point. Card technology and the supported credential profile remain separate compatibility choices.
A clear description of users and existing equipment helps determine the reader, master and mounting arrangement.
Define who receives a card, which spaces they can access and who manages changes. When a card is lost or a user leaves, the building procedure should cover permission updates and how those changes reach the system.
The reader is the physical point where a card is presented. User enrolment, validity and configuration distribution belong to system administration. A shared understanding of these roles helps the administrator and technical team during service.
For each entrance, record the location, enclosure, cards, CAN connection and equipment receiving the command. This connects the individual reader to its role in the building and makes checks or changes easier to discuss.
The QR code helps identify the device when organising and servicing the installation. Technical staff should have suitable access to connections without changing the antenna position or mounting that determines card interaction.
Tell us where users will present their cards, what equipment controls the entrance, and whether cards or a master are already in use. Include the panel material, enclosure space and available cable route.
These details help select the reading profile, master, nodes and output interface. They also inform the responsibilities for administration and ongoing service at the building.
