Why the DM-20 Matters

Not all door control systems are built the same. The DM-20 excels in crucial areas:

• Modular design ideal for renovations and phased installations

• Secure relay outputs capable of managing door locks and alarms

• Tamper detection protects against unauthorized interference

• Multiple supervised inputs enable integrated alarm systems

• Wiegand, RS-485, Modbus, and BioStar connectivity

• Future-ready with optional Wi-Fi and Bluetooth modules

Whether you’re rebuilding an office access system or upgrading a campus network, the DM-20 puts control in your hands.

Adaptive Integration for Diverse Environments

1. Corporate and Enterprise Offices

Deploy DM-20 units at entry doors, server room closets, or restricted zones. The module pairs easily with Suprema readers and the BioStar 2 platform, enabling tailored rules, auditing, and multi-factor entry.

2. Education and Healthcare

In sensitive areas like laboratories or patient rooms, the supervised tool monitors door status with tamper alerts. Safe handling and quick intervention reduce risk.

3. Residential Complexes

Use DM-20 for gated entrances or amenity rooms. Residents gain convenience while security teams monitor every entry remotely.

4. Government and Public Agencies

DM-20’s certification and modular design support high-security deployments, protecting offices with streamline integration and secure communications.

5. Industrial and Utility Facilities

The DIN-rail compatible form allows incorporation into lighting or HVAC panels. Relay control manages not just doors but other electric appliances.

Built-In Safety and Reliability

DM-20 is designed to keep both people and equipment safe:

• Relay ratings accommodate electric strikes, mag locks, and alarm triggers

• Supervised inputs for door status and push-to-exit buttons

• TMP tamper detection sounds alarms if unauthorized access to internal components occurs

• Surge protection shields against voltage spikes via protective varistor circuits

• Auto-voltage sensing for global deployment, auto-selecting 12 or 24 V

Your access system operates reliably—even during power spikes or environmental changes.

Connectivity That Keeps You in Control

Powered by Wiegand, RS‑485, and optional Wi‑Fi or Bluetooth, the DM‑20 offers flexible network options:

• Wiegand I/O for basic card reader integration

• RS‑485 for long-distance, multi-panel communication

Suprema created the DM-20 to work effortlessly in both standalone and integrated architectures.
