DS-K2812

Manufacturer reference

Manufacturer details describe the cited version. Confirm the exact unit and intended system.

Door and reader interfaces

Device class

Access Controller

Door control

Two door control channels, for two doors.

Network communication

TCP/IP communication with 10/100 Mbps self-adaptive wired networking.

Network interface count

One network interface is listed.

Lock-control interface count

2 lock-control interfaces are listed; check the lock circuit and electrical rating separately.

Exit-button input count

2 exit-button inputs are listed.

Door-contact input count

2 door-contact inputs are listed.

Alarm input reference

5 in the alarm-input row; confirm allocation and wiring before selecting connected devices.

Alarm output reference

Four in the alarm-output row; electrical ratings and the connected load require confirmation.

Tamper reference

One tamper interface is listed; the cover describes a tamper switch.

RS-485 reference

One RS-485 interface is listed for the reader arrangement. Confirm topology and supported reader models.

Wiegand reader interfaces

4 Wiegand interfaces; Wiegand 26/34 format reference.

Access policy and stored records

Card capacity

Up to 10,000 card records; separate from the event-log capacity.

Event capacity

Up to 50,000 event records; retention and export settings require confirmation.

Offline operation

Offline operation is described. Confirm the required access policy and power arrangement.

Anti passback

Anti passback is listed; configure and test the required door policy.

Additional access functions

Multi-card, first-person, super-card and super-password functions are listed. Their configuration and permissions require review.

Alarm-event upload

Alarm-event upload is listed. The datasheet does not prove delivery through a configured monitoring or messaging service.

Power-off data retention

The manufacturer describes preserving data when power is removed; review backup and recovery requirements separately.

Multi-door interlocking

Multi-door interlocking is listed; confirm the required door sequence, safety and access policy.

Power, environment and system selection

Mains power reference

100 to 240 VAC in the power-supply row; this is not a lock-output voltage.

With-load consumption

With load: maximum 100 W in the cited sheet. Check the complete connected-load and power design.

Without-load consumption

Without load: maximum 4 W in the cited sheet. This is separate from the with-load limit.

Backup-battery connection

A backup-battery connection is available. Battery inclusion, voltage, capacity and runtime require separate confirmation.

Operating temperature

-20 to 65 °C in the cited sheet. Confirm the actual mounting environment.

Operating humidity

10% to 90%, non-condensing.

Overall dimensions

370 mm wide × 345 mm high × 90 mm deep, corroborated by the complete body drawing. Allow separate mounting and cable clearance.

Illustrated system example

The typical-application diagram names HikCentral Access Control over LAN (TCP/IP), with readers and enrolment equipment. Confirm software version, licensing and the actual device combination.

Selection notes

• References for DS-K2812 in the cited V1.0 filename edition dated 2023-08-17. Confirm the actual hardware, firmware, reader, lock, power and wiring requirements before selection.
• Interface counts are the individual datasheet rows, not a summed channel allocation or a confirmed complete-door kit. Check the reader, lock, exit-button, door-contact and alarm wiring together.
• Wiegand 26/34 alone does not establish every reader pinout, voltage, credential format or third-party device combination. RS-485 bus topology and software compatibility require confirmation.
• The mains-input and consumption values do not establish lock-output voltage/current or usable lock-power budget. A battery connection is not confirmation that a battery is included or that a runtime has been verified.
• The typical-application illustration is not a bill of materials or an active ISD integration. Confirm software/licences, power, readers and enrolment equipment separately.
• ISD supplies products only. Confirm availability, price, lead time, local warranty and the actual supplied equipment separately.
