Modul ovládania dverí rozšírenie / DEE201R Dahua

Integrators expanding a Dahua access control deployment often need to add a door without overhauling the existing panel. The DEE201R extension door controller module connects via RS-485 to compatible Dahua main controllers, delivering one additional door with full in/out reader support. It suits office entrances, server rooms, and internal security doors where incremental expansion is more cost-effective than adding another main panel.

Key specifications

• Controls 1 door with 2 RS-485 reader interfaces for entry and exit readers
• Communicates with main controller via RS-485 at 9600 bps
• Inputs: 1 door sensor, 1 exit button, 1 alarm input
• Outputs: 1 lock relay (NO/NC) and 1 alarm output
• Power supply: 9-15V DC, consumption under 100 mA (without load)
• Operating temperature: -30°C to +60°C; humidity 0–90% RH non-condensing
• LED indicators for power, communication, and status
• Wall-mount installation, PC+ABS housing
• Overcurrent, overvoltage, and reverse current protection

Why choose it

This module integrates seamlessly with Dahua ASC2204C and ASC1204C series panels, preserving your existing wiring and management software. Its wide temperature range and robust protection circuits ensure reliable operation in indoor utility areas or sheltered outdoor enclosures. The NO/NC relay output supports both fail-safe and fail-secure locks, giving flexibility for different door types.

Ideal use cases

• Adding a second door to a small office access system
• Securing internal doors in server rooms or laboratories
• Expanding a multi-door installation without replacing the main controller
• Retrofit projects where existing Dahua panels need extra capacity

Good to know

The DEE201R is an extension module only; it requires a compatible Dahua main controller to operate. It is not a standalone device. Installation should be performed by qualified technicians familiar with low-voltage access control wiring. The module's compact size and wall-mount design allow discreet placement near the controlled door, minimizing cable runs.
