DIU 210 Door Interface Unit Features that make a difference: • Door Interface Electronics held on one board • Provides a coded lock serial interface between door hardware and card reader • On site selectable for 12V or 24V lock output • Fire alarm and break glass inputs for emergency door release • Designed for ease of installation and maintenance using 2 part connectors throughout • Compliant with EN55022 (emissions) and EN55024 (access control immunity) • Backup battery connection for emergency power The Door Interface Unit (DIU 210) is designed primarily to provide power to a door lock, as well as local power to a CEM reader when a high level of security is required. Upon a valid swipe at the card reader, the reader will instruct the DIU (over the RS485 communications channel) to activate the appropriate output to release the lock using a coded data signal (i.e. coded lock). It has onboard inputs which can be used to monitor conditions such as a fire alarm or activated Break-glass condition. The DIU 210 improves door security, by allowing the installer to locate lock controls on the secure side of a door, with an intelligent CEM reader on the unsecured side. The DIU 210 communicates with an intelligent CEM reader over a single pair RS485 cable. As an added benefit, the DIU 210 monitors the status of all standard door monitoring inputs; inputs on an intelligent CEM reader are free for use as general purpose inputs. The DIU 210 is supplied in a steel enclosure complete with power supply backplane and an output for an additional door holder. www.cemsys.com 1. 2. 3. 4. 5. 6. 7. 8. 9.

Minimum: 57mA (excluding locks and heads Maximum: 175mA (including locks and heads) 8 inputs can be used for alarm/status monitoring devices directly to the DIU 210. These devices are used to monitor door sensors, DIU tamper and battery alarms and fire/ break glass emergency conditions. If an input from the fire alarm system or break glass unit changes state, the power to the door lock is automatically dropped; this hardware-controlled facility ensures that the door opens in an emergency situation. Details of alarm conditions can be sent directly to the door controller or to the host, via the card reader, for central alarm notification Board Protection The DIU 210 has been designed to meet the UL294 standard providing resistance to power supply tamper, limiting the current to a reader so that shorting together the 12 Volt terminals prevents the lock from opening. Reader inputs The DIU 210 can also monitor the status of all the door furniture inputs, freeing up to another eight inputs on the intelligent CEM readers for general purpose input monitoring.
