3.11.1 Configuration information
Using a CEM DIU230 provides the highest level of security at a door, removing power for the
lock and input monitoring away from the door reader. The DIU is a PoE+ device and does not
require specialist electrical qualifications to install.
Input configuration
When a DIU230 is used with a emerald terminal, the DIU controls the main CEM reserved
inputs and the inputs on the readers become spare. The exception to this is input three on the
emerald terminal (input B in the table below) which maintains its status as being used for
interlock mode.
.
Important
If a decision has been made not to connect a fire and break glass units to the DIU the inputs must be linked out to
ensure that the DIU functions normally. The tamper input must also be linked out when not in use to prevent
alarms being generated on AC2000.
