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)
