Suprema releases multi-door access control module

September 2, 2015 - 

Suprema announced it has released DM-20, a secure door control module designed to securely connect multiple peripherals from Suprema biometric devices.

When combining DM-20 with Suprema’s biometric platform BioStar 2, system designers will have greater flexibility and scalability to design and deploy centralized access control systems.

Additionally, using the module with any Suprema access control terminal enables the device to function as a secure central controller.

The module allows for a simple upgrade to a smart access control system and uses existing RS485 or Wiegand networks without the need of establishing a new IP-based network.

Users can connect additional DM-20 units via a daisy chain configuration to support up to 32 doors in combination with Wiegand readers or Suprema devices.

Each module features a RS485 connection, 2 wiegand in/out ports and up to 4 relay ports for a wide range of installation applications.

Meanwhile, the 2 Wiegand ports can be used to connect third party readers that can be set up as doors within BioStar 2.

The module also fully supports 4 TTL inputs and an additional 4 supervised inputs that detect the voltage flow on the circuit and allow the system to monitor input devices.

“DM-20 delivers ultimate flexibility to system designers and installers,” said Young S Moon, VP of Suprema. “Its functions expand the ability of Suprema terminals to accommodate mid to enterprise level access control needs, and enhance security by replacing the conventional systems with biometrics or smart reader controllers.”

Suprema’s DM-20 is a BioStar 2 exclusive accessory and will support all BioStar 2 compatible devices and accessories.

Previously reported, Suprema released BioStar 2.1, the latest major update to its web-based IP access control management software.
