Johnson Controls expands CEM access reader portfolio

Belfast, UK

The Johnson Controls CEM DCM200 with enclosure

Johnson Controls has further strengthened its CEM Systems range of access control solutions with the launch of the intelligent DCM200 door control module.

Designed to be highly secure and to directly interface with CEM Systems’ AC2000 access control software versions 10.2 or higher, the DCM200 is a two-door controller which is able to support a combination of up to four Wiegand or CEM Systems approved Open Supervised Device Protocol (OSDP v2) smart card readers.

OSDPv2 is a secure access control system protocol standard developed by the Security Industry Association for peripheral devices. With secure AES 128 encryption, it provides bi-directional communications for connecting OSDPv2 compliant readers to DCM200 control panels and with advanced security features, eliminates the threat of Wiegand signal cloning.

The cyber security credentials of the DCM200 are further enhanced with the utilisation of secure TLS v1.2 communications to the host server and a Secure Element on-board for secure key storage, updates and boots, whilst offering future support for 802.1x network authentication.

Easy to install

The DCM200 has been designed as easy to deploy with the installer configuring the IP address by simply selecting DIP switches using DHCP or auto-configuration. When connected to an Ethernet network, the DCM200 will then self-configure and receive the database of up to 50,000 cardholders in under 2 minutes.

Designed with both the end-user and installer in mind, the DCM200 comes with a dashboard which can assist with local and remote troubleshooting, as well as the monitoring and configuration of the DCM200 and any equipment connected to it. The dashboard provides operators with visual indicators and data on the status of the network, power, doors, inputs/outputs and database status and allows operators to remotely configure network settings and set limits for outputs, such as read heads, locks and auxiliary outputs.

Using powerful 32-bit processors, the DCM200 gives full off-line verification and decision making at the point of entry when host communication is not available, whilst bi-directional control on two doors can be achieved when OSDPv2 compliant readers are used in an entry/exit configuration.

Future proof

With the ability to support any combination of Wiegand or OSDPv2 readers, the DCM200 offers a future proof solution for end-users who may wish to migrate from Wiegand readers to more secure readers over time.
