Symmetry™ M2150 8DBC Controller

The multiNODE is a key feature of an access control system. It provides distributed intelligence, resilience in the event of network failure, and fast response to access requests.

The Symmetry multiNODE M2150 8DBC is an eight door intelligent controller that provides flexible configurations for up to:

• 16 Readers (with addition of 8DC 8 door controller)
• 56 Inputs
• 56 Auxiliary Outputs
• 250,000 Cardholders

The Symmetry multiNODE M2150 8DBC supports connections to a client PC via the Local Area Network, hard-wired communications port or remote dial-up modem.

Each Symmetry multiNODE M2150 8DBC controller fully supports connection of up to eight readers and doors. The configuration is flexible and can be expanded up to 16 readers using a range of door controllers. In addition to direct LAN connection, the controllers can be networked to form a chain of controllers. There can be one or more chains, with up to 32 controllers per chain.

Each chain of Symmetry multiNODE 2150 series controllers communicates with PCs running the feature rich Symmetry Professional or Symmetry Enterprise security management software. The security management software is used to set up the rules of access control, monitor alarms, produce reports and administer one or more facilities.

Communication schemes may be configured as follows:

• Via a LAN/WAN connection, using an optional network-interface module card
• A hard-wired single chain via an RS-232 to 20mA converter
• A direct hard-wired single chain via the on-board RS-232 port
• Fault tolerant bi-directional communications by connecting the last controller on a chain to a second port of the monitoring PC
• Dial-up via modems, providing low cost management for remote sites requiring centralized administration
• Support for secondary fallback reporting of alarms via network or dial-up modem, should the primary network path be unavailable
• AES Encryption option available for secure LAN connection

Reader Technologies & Card Formats

The Symmetry multiNODE 2150 controller supports a full range of reading technologies including Magnetic Stripe, Smart card, Proximity, Biometrics and Wiegand (via a Wiegand Interface Module). A number of default card formats are programmed as standard and there is a capability for custom formats to be defined. This is particularly important when integrating existing cards with a new system.

Symmetry multiNODE 2150 Configurations

The Symmetry multiNODE 2150 controller is supplied with enclosure and power supply. Enclosures have a removable hinge lockable lid, tamper switch and power indicator as standard.

When required, enclosures can contain an integrated power supply which may be used to provide the 12VDC supply for the controller and its associated readers. The enclosure power supply board requires an 18VAC external supply. A battery recharge facility is included, with space within the enclosure to accommodate a 12V 7AH maintenance free rechargeable battery. An optional transformer is also available.

The Symmetry 8DBC can be integrated at a peer to peer level in a single enclosure with the Symmetry™ ENVS® (Edge Network Video Servers) to provide a totally integrated security management solution.
