Smart door control set: MIFARE reader with keypad, KD-N3-CTRL door controller and exit button

Overview

The problem. Doors in factories and campuses are scattered: outer barriers, warehouse doors, cold rooms, passages between production areas. With wired access control panels, every door needs reader, lock, contact and exit-button cabling; distance and inter-zone runs drive up the cost. Existing plants often have no cable route at all. Remote-type RF door openers, on the other hand, do not record who opened the door, can be copied and do not talk to a central unit. During a fire, nobody knows the state of the doors.

In the field today. The current generation makes the control part of the door chain wireless: door status is monitored and doors are opened and closed from the central touch panel; battery-powered button transmitters at remote points such as the guard booth or on forklifts send open commands to the door receiver over 433 MHz. The door receiver has relay outputs; frequency, channel and output power are set from its LCD menu.

New generation. A wireless door controller at every door: lock relay, door contact, request-to-exit (REX) button and MIFARE reader are wired locally, and the controller talks to the central unit over 433 MHz LoRa. The permission table is cached at the door, so cards are still read if the central unit is offline; events (card, door held open, forced entry, remote open) are sent to the central unit and logged. The door map, manual open/close, zone- and time-based access levels and anti-passback (on doors with entry and exit readers) are managed from the touch panel or a web interface. The reader, event log and web interface are targets of the new generation.

Fire integration. When integrated with the Wireless Fire Alarm System (Firesens), the assigned doors open or lock automatically on an alarm, and door status appears on the fire map.

Applications

  • Factory entrances
  • Passages between departments
  • Offices and administrative buildings
  • Staff entry with turnstiles
  • Warehouses and cold rooms
  • Archive and chemical rooms
  • Vehicle barriers
  • Food and packaging plants
  • Public facilities
  • Remote opening from the guard booth: vehicle barriers and outer doors are opened with a battery-powered button or from the central panel.
  • Restricted access zones: warehouses, cold rooms, archive and chemical rooms; hygiene zones in food and packaging plants.
  • Doors linked to the fire system: assigned doors open or lock on a Wireless Fire Alarm System (Firesens) alarm.
  • Adding to an existing wired system: the door controller can connect to an existing panel via relays and contacts; card database integration via CSV/API is planned.

Choosing the lock. Behavior on power loss depends on the lock type: a magnetic lock releases (fail-safe, escape doors), an electric strike stays locked (fail-secure). A battery-backed supply is recommended; escape-door compliance is provided by the lock manufacturer's certification.

Frequently asked questions

Will the door still open if the link to the central unit is lost?

In the new generation, the door keeps reading cards from its local permission cache; remote opening waits until the link is back. In the current generation, the door is opened with a local button or key.

What happens to the door during a power cut?

It depends on the lock type: a magnetic lock releases (fail-safe, escape doors), an electric strike stays locked (fail-secure). A battery-backed supply is recommended.

Which cards can be used?

The new generation will work with MIFARE 13.56 MHz cards (Classic, DESFire UID); your existing staff cards are usually compatible, which we check with a sample card. 125 kHz is optional.

How many doors and cards are supported?

The new generation targets 64 doors, 10,000 cards and 100,000 events per central unit. On the current panel, doors are addressed by ID number.

How does anti-passback work?

On a door with entry and exit readers, a second pass in the same direction is denied or flagged. In the new generation, this check keeps running locally at the door even if the central unit is offline.

Can it be added to an existing wired access system?

Yes. The door controller can connect to the existing panel via relays and contacts; card database integration via CSV/API is planned.

What happens to the doors during a fire alarm?

With the Wireless Fire Alarm System (Firesens), the assigned doors open or lock automatically, and door status appears on the fire map.

Can the remote be copied?

In the new generation, AES-128 encryption with a counter prevents copying. In the current generation, packets are validated by system ID and CRC.

What about warranty and service?

A 2-year warranty is planned; service is provided in Ankara. Locks and readers are covered by their manufacturers' warranties.
