Hikvision DS-K2M0016A Distributed elevator controller, 2 RS- 485,2 alarm,16 relay,1buzzer, DC12V

Model: DS-K2M0016A

Who This Is For

When floor-by-floor access restriction in a multi-storey building is the priority, the Hikvision DS-K2M0016A Distributed Elevator Controller gives installers a purpose-built solution for managing lift access across up to 16 floors from a single unit. Designed for integration into Hikvision's access control and intercom ecosystem, it connects via 2 RS-485 ports, supports 2 alarm inputs, controls 16 relay outputs for floor button restriction, and includes a built-in buzzer for local alerts - all powered from a DC12V supply. This is the unit specified by systems integrators, security contractors, and facilities managers on residential apartment towers, commercial office buildings, and hotels where lift access needs to be tied to credential verification. It suits projects where the elevator controller must work alongside an existing Hikvision access control or video intercom system rather than operating as a standalone device.

What This Controller Actually Does

Who Buys This Model

• Systems integrators on residential apartment towers: Specifying Hikvision access control throughout a new build and needing a dedicated unit to restrict elevator floor access per credential type - residents, staff, and visitors each assigned specific floor permissions.
• Commercial office building contractors: Tiering floor access so tenants on one level cannot reach another tenancy's floors, using the 16 relay outputs to map directly to the lift car's floor button array.
• Hotel and hospitality installers: Limiting guest lift access to their registered floor only, integrating the controller with the Hikvision intercom or access control platform already managing lobby and room entry.
• Facilities managers upgrading aging lift access: Replacing key-switch-per-floor arrangements with a centralised relay-based solution that can be managed and audited from the Hikvision access control software.

Honest Assessment

The DS-K2M0016A handles its specific job well - distributing elevator floor control across 16 relay outputs via RS-485 within a Hikvision access control or intercom system. The distributed architecture means the unit sits close to the lift panel, reducing wiring runs from the main controller, and the dual RS-485 ports give flexibility in how it connects upstream. The intercom integration is a genuine advantage on apartment and hotel projects where visitor-to-floor workflows need to be automated. What it will not do is operate as a standalone access controller - it requires an upstream Hikvision access control system to function and is not compatible with third-party platforms without custom engineering. Buildings with more than 16 floors requiring elevator restriction per lift car will need multiple units planned carefully. Available through Security Australia, this controller suits Hikvision-committed installations where lift control is one part of a broader integrated system, not a one-product solution.

Before You Buy

Quick Fit Check

• Good match if: You are installing a Hikvision access control system in a multi-storey building and need to restrict lift floor buttons to credentialed users - the 16 relay outputs map directly to floor button wiring in the lift car panel.
• Good match if: Your project already uses a Hikvision video intercom system at the lobby and you want lift floor access granted automatically when a visitor call is answered - the DS-K2M0016A supports documented integration between the elevator controller and Hikvision intercom platforms.
• You may need a different model if: Your site uses a non-Hikvision access control platform - this controller communicates via RS-485 within the Hikvision ecosystem and is not a standalone or open-protocol device. Look at access-control-agnostic elevator control modules better suited to mixed-brand installations.

Key Features & Technical Specifications

Real-World Scenarios

How It Compares

• Choose this if: Your project is built on Hikvision access control or Hikvision video intercom and you need distributed, per-floor relay control for up to 16 floors per lift car - the RS-485 architecture keeps it tightly integrated with the rest of the system.
• You may need a different model if: Your building has a non-Hikvision access control backbone - a platform-agnostic elevator controller with open-protocol outputs would be a better fit for mixed-brand or retrofitted installations.
• Pairs well with: A Hikvision access controller (for upstream RS-485 management), Hikvision video intercom master stations (for visitor-to-floor automation), and a Hikvision access control management platform for credential mapping and event logging.

Common Questions

1. Will this elevator controller work with a non-Hikvision access control system?

   No. The DS-K2M0016A communicates via RS-485 as a subordinate device within the Hikvision access control ecosystem. It is not an open-protocol device and has no documented compatibility with third-party access control platforms. If your site uses a different brand of access controller, you would need an elevator control module that supports open protocols or the specific integration your platform requires.

2. How many floors can this unit control per lift car?

   16 floors per unit. The DS-K2M0016A has 16 relay outputs, each mapped to a single floor button in the lift car. For buildings with more than 16 floors on a single lift car, additional units would need to be planned and confirmed as supported by your access control software configuration before specifying.

3. Does this controller work with Hikvision video intercom systems?

   Yes. Hikvision provides documented guidance specifically for setting up the DS-K2M0016A to work alongside their intercom platform - a setup guide is available in the Downloads section below. This allows a visitor granted lobby access via an intercom call to have a specific floor relay released automatically as part of the same access event, without requiring a separate credential presentation inside the lift.

4. What power supply does the DS-K2M0016A require?

   DC12V. The unit is powered from a DC12V supply, consistent with standard Hikvision access control power infrastructure. It can typically share a cabinet power supply with card readers and other access control devices, provided the supply has sufficient current capacity. Confirm your supply's total current budget before adding this unit to an existing installation.

5. What are the 2 alarm inputs used for?

   They connect to dry-contact sensors such as tamper switches or door contacts within the lift cab or shaft. When triggered, the alarm event is reported back through the RS-485 connection to the upstream Hikvision access controller and logged by the management software. This gives installers a way to detect unauthorised interference with the lift control wiring without running separate cabling to a standalone alarm panel.

6. Does this unit need one controller per lift car or can one unit manage multiple lifts?

   One unit per lift car. Each DS-K2M0016A manages 16 relay outputs for a single lift car's floor buttons. A building with 3 lift cars requiring floor restriction would need 3 units - one per car - all connected upstream to the Hikvision access control system. Confirm your software licence and access controller channel capacity covers the full number of units required before ordering. This product is stocked by Security Australia alongside compatible Hikvision access control hardware for complete elevator control installations.

Cabling Considerations

• RS-485 Cable: Use twisted-pair screened cable (Belden 9841 or equivalent) for all RS-485 runs between the DS-K2M0016A and the upstream Hikvision access controller. Screen the cable at one end only to prevent ground loops.
• Max RS-485 Cable Run: Up to 1200m at lower baud rates under ideal conditions. Elevator environments introduce electrical noise from motor drives - keep RS-485 cabling physically separated from power cabling and lift motor wiring wherever possible.
• Relay Output Wiring: 16 relay output connections run from the DS-K2M0016A to the corresponding floor button terminals on the lift car's internal control panel. Confirm the lift car's button wiring is dry-contact compatible before installation and coordinate with the lift service provider if access to the panel is required.
• Power Cabling: DC12V supply wiring should be run from a dedicated security power supply in the building's security cabinet. Use adequately rated cable for the cable run length to avoid voltage drop, and ensure the power supply includes battery backup if the site requires access control continuity during mains failure.
• Alarm Input Wiring: Standard 2-core alarm cable is suitable for connecting tamper or door contacts to the 2 alarm inputs. Keep alarm cable runs short and within the lift shaft where possible to reduce exposure to electrical interference.
