OVERVIEW  
power via a single Cat5/6 cable  
The DIU 220 (PoE Door Interface Unit) combines Ethernet communications and  
sufficient power to support a complete door set, including an In reader, Out reader and  
a standard 650mA maglock, over a single Cat5/6 cable. The DIU 220 eliminates the  
need to include a power supply unit (PSU) at the door and expense of providing mains  
power to the PSU.  
• Eliminates to need to have mains  
power and a PSU at the door  
• Provides local power for:  
In reader  
Out reader  
The DIU 220 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. It has onboard  
inputs which can be used to monitor conditions such as a fire alarm or activated  
break-glass condition.  
Maglock  
Sounder  
Door Holder  
The DIU 220 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  
220 communicates with an intelligent CEM reader via the readers slave communication  
channel. Upon a valid swipe at the card reader, the reader will instruct the DIU (over  
the communications channel) to activate the appropriate output to release the lock  
using a coded data signal (i.e. coded lock).  
• 11.5V @ 1.6A power output*  
• Door Interface Electronics held on  
one board  
• Provides ‘coded lock’ interface  
between door hardware and  
card reader  
As an added benefit, the DIU 220 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 220 is supplied in a plastic enclosure complete with PoE backplane and an  
output for an additional door holder.  
• Fire alarm and break glass inputs  
for emergency door and holder  
release  
• Weigand interface for 3rd party  
exit reader.  
• Designed for ease of installation  
and maintenance using 2 part  
connectors throughout  
• Compliant with EN55022  
(emissions) and EN55024 (access  
control immunity)
