KERONG Centrally Supplied Locker System

KERONG is the manufacturer's choice — the company behind the lock hardware that many locker manufacturers and smart locker operators build their products around. One control unit manages up to 48 locks, with units chainable to manage large locker banks. KERONG also offers full OEM/ODM customisation, making them the partner of choice for locker manufacturers who want to brand their own smart locker solutions.

How Does KERONG Centrally Supplied Lock System Work?

Understanding the architecture helps when specifying or integrating these systems. A typical KERONG centrally supplied locker installation consists of four layers:

Layer 1: The Electronic Locker Lock

The physical lock unit mounted on each locker door. KERONG's centrally supplied locks — such as the KR-S1113B, KR-S99S — are motor-driven or solenoid-driven devices designed to receive power and control signals via wired connection. They have no internal battery and rely entirely on the central power supply.

Each lock includes:

• A locking mechanism (motor bolt, rotary latch, or solenoid)

• Status LEDs (occupied/vacant, open/closed)

• Optional RFID reader integrated into the lock face

• Optional internal LED lighting and USB charging ports (KR-S1113B)

• Signal lines for bi-directional communication

Layer 2: The Control Unit (CU)

The Control Unit is the sub-controller that manages a cluster of locks. KERONG's KR-CU16 control units can each manage up to 16 electronic locker locks, with multiple control units chainable to manage large locker banks of any size.

Control units handle:

• Power distribution to connected locks

• Signal routing between locks and the central system

• Real-time status reporting (occupied/vacant per locker)

• Local alarm event processing

Layer 3: The Bus Unit (BU) / Master Controller

The Bus Unit aggregates multiple Control Units and serves as the gateway between the lock network and the higher-level management software. It communicates via TCP/IP or RS485 — making integration with existing building management systems, access control platforms, and HR software straightforward.

Layer 4: The Management Software / Terminal

The top layer is where facility managers and operators interact with the system. This can be:

• A central touchscreen terminal located in the locker area

• PC-based management software accessible via any browser

• A cloud-based platform with real-time dashboards, user management, and reporting

• An API integration with third-party access control or ERP systems

Users can also interact via a self-service terminal, selecting and releasing their own locker without any staff involvement.

In summary, KERONG is primarily a manufacturer/supplier of the lock hardware and control boards (often used by locker manufacturers to build their products), contact KERONG and discuss more details about KERONG Centrally Supplied Locker System.
