Doors access control systems

Explore the main parts of an access control system: control devices like electric locks, monitor devices such as door contacts, and servers or control panels with readers and exit buttons.

Explore the main electric lock types—door strike, bolt lock, and magnetic lock—and learn how coils and electromagnetic fields move bolts and latches to control door operation.

Explain how a central access control server stores credentials, manages time-based access, coordinates readers and doors, and supports emergency mode with BMS and CCTV integration.

Compare fail safe and fail secure in access control: fail safe unlocks on power interruption to keep life-safety exits open; fail secure locks during outage to protect critical areas.

Learn how RFID cards power their internal microchips via the reader's electromagnetic field, using a copper antenna coil to transmit the tag ID to the reader for access control.

Compare 125kHz and Mifare RFID cards, noting 125kHz transmits ID with low power and is easy to duplicate, while Mifare uses an acknowledge step for higher security.

Map controller/server, inputs (reader, exit button, motion detector, door contact), and outputs to the lock; software uploads credentials and schedules and enables integration with other controllers, CCTV, and fire alarms.

Apply access control to limit entry to specific zones by issuing electronic credentials read by readers, enabling multi-level security and generating transaction reports.

Explore access control applications across entrances, exits, time-based access, multilevel security, elevators, attendance, mantraps, and hotel use of Mifare cards for rooms, payments, and power control.

Identify various access control types, from standalone electronic locks and card readers to swing gates. Understand how servers, PoE, RS-485, and mobile access enable integrated, secure elevator and building access.

Plan for access control by identifying devices and client requirements, allocate door components with push button, reader, junction box, and connections to power, data, server, and fire alarm.

Explore a hotel access control tender design and its single line diagram, detailing junction boxes, readers, locks, branch and main servers, power and data sockets, and fire alarm module integration.

Outline converting tender design into per-door access control with optional centralized server, plus a riser and shop drawing linking doors to branch and main servers via cat6 for approval.

Explore branched access control servers for door systems, featuring RS-485 and Ethernet communication, two readers per unit, eight inputs, bell outputs, and expandability with modules.

Demonstrate on site access control servers, branch server modules, power supply with stabilizer and UPS, LED indicators, enclosures, and two doors, two reader wiring and Ethernet connections to security software.
