AXON Master Premium provides access control for elevators, doors and garages through two isolated CAN branches. EMI filtering, ESD protection and monitored node power are complemented by Ethernet, PoE for the controller and onboard LTE.
An entrance for residents, another for service staff, and several floors with restricted access. Group readers and nodes around the spaces they serve, with two CAN branches connected to the same controller.
Organize readers and nodes across two CAN branches. One can serve a group of entrances and the other a separate area, following the layout of the building.
The controller can be installed in a cabinet or inside the elevator car. Output nodes connect to panel signals; the card permissions and system configuration determine which requests are authorised.
Place the reader and output interface near the access point. The command connects to a suitable input on the gate or barrier controller.
A building may have a main entrance, several elevators, a garage and technical rooms. Each is an access point, but each serves different people and needs a different connection. AXON Master Premium is the central controller that organises the installation through two CAN channels, with nodes and readers close to where they are needed.
The Premium model focuses on electrical separation and branch monitoring. Each CAN channel has galvanic isolation, electromagnetic noise filtering and ESD protection. Both branches also have separate power protection and measurement. This gives communication and power distribution clearly defined paths throughout the installation.
AXON Master Premium combines Ethernet, PoE power for the controller and integrated LTE. Its two local SSR contacts can be expanded with nodes when the installation needs more outputs. For the building manager, the configuration follows the entrances, users and services. For the installer, each interface has a defined role.
The same master can be installed inside or outside the elevator cabin. From an external cabinet, it can serve landing readers, building entrances, the garage and vehicle barriers, while relay nodes inside the cabin connect to floor signals on the same compatible CAN lines. Using a common master and a small range of expansion nodes reduces the number of board types needed across the building.
Each master stores up to 1,000,000 cards and supports up to 240 addressed subordinate devices, including readers and output nodes. Node8 adds eight SSR outputs; other node variants provide eight or more outputs according to their model. Device count, output count and access-point count are planned separately.
The user presents a card to the reader. The system connects that identification with access permissions and the signal required by the door, elevator panel or garage controller.
The RFID reader is where a resident, employee or technician presents their card. AXON CAN readers bring this interaction to the entrance or control panel and communicate with the rest of the system.
Master Premium acts as the controller. The card technology and reading profile are selected together with the reader and installation configuration. This lets you choose the identification device to suit the place where it will be used.
A resident may need access to the building entrance, the garage and their own floor. Employees may use designated work areas, while the maintenance team needs access to technical rooms.
These groups are defined when users and cards are managed. Access restrictions work best when they reflect how the building is used: who needs to enter, which spaces they need and what responsibilities they have.
Once access is authorised, the output interface connects to the control signal of the relevant equipment. Master Premium provides two local SSR contacts for button signals; output nodes extend this part of the installation.
In an elevator, the connection can act on the signal for an authorised floor. A door or garage uses the appropriate command input. Locks, motors and their power supplies are handled by the relevant power interfaces.
One access plan can cover several types of space. Readers, nodes and command interfaces are selected around the existing equipment and the way people move through the building.
Elevator access control links each user’s card to the floors they are allowed to reach. In residential buildings, this helps organise access for residents; in offices and hotels, it separates floors according to their use.
The modular controller can be planned inside the elevator car or in a cabinet. Nodes add contacts to suit the panel. The connection handles access command signals; movement and safety functions remain with the elevator system.
The main entrance, an office, a storage room and a technical room may each have different user groups. RFID cards and permissions organise access to these spaces, with readers near the entry points.
Each door is assessed together with its existing controller, lock, power supply and exit button. The command contact is selected to match the equipment interface, along with the arrangements for free exit and the installation requirements.
In a shared garage, access is linked to the users who are entitled to enter. Reader and node positions are planned around the access point, cable routes and existing gate or barrier system.
The command connects to a suitable input on the gate or barrier controller. Its own automation continues to manage the motor, sensors and protective functions. Compatibility is determined from the specific equipment model and signal.
A complex with several entrances needs a clear map of its areas and responsibilities. The two CAN branches can organise groups of nodes by location and cable routing, with readers placed close to the people using them.
Residents, staff and service teams may have different needs within the same building. Planning these together makes it easier to define readers, contacts and power distribution before installation.
CAN A and CAN B are separate communication channels. Each has its own isolated interface, node connections and associated power supply.
Both CAN branches can serve compatible readers and relay nodes. Devices outside the cabin and output nodes inside it can share the same compatible lines, so a master outside the elevator can manage both the cabin panel and building access points. Allocate the branches around cable routes, electrical requirements and the position of the equipment.
This gives local devices two clearly defined communication paths. Cabling, termination and power are considered separately for each branch. The two channels have distinct roles; they do not by themselves provide automatic failover.
When Premium’s two local contacts are not enough, nodes add outputs where the commands are needed. AXON Node8 provides eight SSR contacts and CAN connectivity for this role within the system family.
CAN IN and CAN OUT on a node continue the same bus. On Premium, CAN A and CAN B are separate channels. This distinction matters when preparing the wiring plan and assigning nodes to each branch.
The AXON family also includes controllers with many outputs in one elevator car unit, such as CCU-32. The modular architecture uses a master and nodes to distribute contacts around the installation. Both approaches start with the panel and the access points that need to be managed.
The modular system supports up to 240 addressed subordinate devices per master. A device can be a reader or an output node with several contacts; this is not a limit of 240 relays. Node8 has eight SSR outputs, and other node variants provide eight or more outputs according to their model. Size each bus segment and its power supply for the devices connected to it.
In a building, cables run near power supplies, motors and other electrical equipment. Premium uses complementary measures for circuit separation, electromagnetic noise and electrostatic discharge.
Devices spread across a building can have different electrical references and power supplies. Each Premium CAN channel uses an isolation barrier to separate the control side from the side communicating with field devices.
This electrical separation supports communication between the controller and devices distributed throughout the building. Power and cabling are planned for each branch according to the installation conditions.
Electrical equipment near a cable can generate noise that affects communication. Premium includes EMI filtering on both CAN channels to address this interference at the connection interfaces.
Filtering works alongside the choice of cable, its route and appropriate termination. These are considered when the controller is placed near an elevator panel, automation equipment or other electrical devices.
Electrostatic discharge can occur when equipment and connections are touched. Premium includes ESD protection on both CAN interfaces and on the Ethernet interface.
ESD protection, EMI filtering and galvanic isolation have complementary roles. Together with appropriate installation, they form part of how the controller is integrated into the building’s electrical environment.
The enclosure, grounding and cable organisation complement the controller’s protection measures. In a cabinet that brings together networking, power and access signals, each connection needs a defined position and route.
Planning takes account of nearby equipment, access for servicing and environmental conditions. The controller and its installation are considered together as parts of the same solution for the building.
Node power is planned separately from controller power. The two branches have separate 12–24 V DC inputs, with individual protection and measurement.
Each branch includes protection against undervoltage, overvoltage, overcurrent and excessive temperature. These functions apply to the power distributed to the devices on that branch.
Power supplies and cables are sized for the actual load, including the devices and cable distances on each branch. Keeping the branches separate makes power planning clearer as the installation expands.
The node supply includes protection against reversed polarity and reverse current. These measures complement the protection provided for each branch where it connects to its power source.
The A/B division helps document sources and loads clearly during installation and servicing. Connections are checked against the installation plan before power is applied.
Each branch provides voltage and current measurements. This allows power requirements and device loads to be considered separately for the two groups of devices.
The measurements support monitoring and diagnostics according to the configuration. How they are displayed and used by the system is defined as part of the platform integration.
The controller can be powered through its own 12–24 V DC input or through the PoE module on its Ethernet connection. This offers another way to organise the controller where the network infrastructure supports it.
Nodes use the external supplies for the two branches. The controller’s PoE does not power them; the power budget for local devices is calculated separately for each branch.
Platform communication, node connections and equipment commands are different parts of the system. Premium brings them together in a controller with dedicated interfaces.
The RJ45 port connects the controller to the local network for communication with system services. Ethernet is part of the building infrastructure and is planned alongside the location of the control cabinet.
Planning covers the network connection, PoE power where used and access to AXON services. CAN A/B handle communication with local devices.
Master Premium includes integrated LTE connectivity. This differs from Master Lite, where cellular connectivity is added through an optional external module.
Cellular use is planned together with the configuration, antenna and mobile operator service. How LTE works alongside Ethernet is defined in the complete system configuration.
The two local SSR contacts provide an interface for button signals. They can be used when the command point is close to the controller and the electrical interfaces are compatible.
Nodes provide additional contacts or serve more distant points. The contacts do not directly power locks, motors or mains-voltage loads; those devices require an appropriate interface.
Manage cards, schedules and service validity centrally, then apply the rules at the selected access points. Connected masters exchange updates with the platform in real time, so one building or several managed properties can use a consistent administration process.
Each master stores up to 1,000,000 cards. Administrators assign users to entrances, floors, doors, garages or barriers and set the schedules and validity periods for those permissions.
A resident, employee or service contractor can therefore have access to selected points at selected times. When permissions change, the platform distributes the updates to connected masters in real time. A disconnected master receives remote changes only after its connection returns.
The platform records maintenance work, payments and service validity. Administrators choose which access points are linked to a validity or payment deadline. When that deadline expires, access is blocked at the designated points, while residents receive advance notice on their phones.
This makes the rule specific to the service and the access point: for example, elevator access or a garage entrance can be selected without applying the same restriction to every door. Where a point is an emergency exit, the rule can restrict entry only; escape and emergency release remain free. The master applies access rules, while payment records and collection are managed by the platform.
The platform distributes card, permission and configuration changes across connected masters in real time. An administrator can also remotely deactivate a selected reader or subordinate node without disabling every access point in the installation.
Communication between subordinate devices and the master is encrypted, as are the links between the master and cloud services. Ethernet and integrated LTE provide network access; MQTT carries system messages. Remote changes require a working connection to the receiving master and device.
A phone can access local master diagnostics through the connection supported by the model. For Premium, the phone uses the local network connected to the master’s Ethernet port. This does not require an onboard Wi-Fi or Bluetooth interface on Premium.
Local diagnostics help the installer inspect the master and its connected devices at the building. Remote administration remains available through the platform when the system has a network connection.
Choosing a controller becomes easier when the spaces, equipment and management process are understood. A shared plan connects access decisions with installation decisions.
List the entrances, floors, doors, garages and service areas. For each one, identify who needs access and where the reader should be installed.
This helps establish the contact count and user groups. The number of doors or floors is a starting point; the interface on each piece of equipment determines the actual connection.
Identify possible positions for the controller and nodes, cable routes, Ethernet points and power sources. The two CAN branches and their individual power requirements can then be planned.
The same approach applies to international projects. AXON’s team is based in Kosovo, but system planning is not limited to that market. Local infrastructure, installation requirements and support arrangements are assessed for each building.
The building manager defines access rules and the services to be tracked. The installer provides details of the panel, doors and automation equipment. The AXON team brings these together to select the controller, readers and nodes.
