Technical Specifications - CEM Systems Door Interface Unit DIU 210 Specification

interfaces
The DIU 210 provides direct interfaces to the following devices:
• CEM Card Reader
• Electric Door Lock
• Fire Alarm System
• Break Glass Unit
• Exit Push Button
• Inputs from alarm devices
Up to 8 inputs can be wired from 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 the inputs on the intelligent CEM
reader for general purpose input monitoring.
PSU Backplane Board and Enclosure
The DIU 210 is supplied with a steel enclosure and backplane
board providing a mains input PSU, battery charging
capabilities and door holder connections.
