CEM Systems Compact Door Interface Unit DIU 200 Specification

DIU 200 Module
Compact Door Interface Unit
OVERVIEW
The Compact Door Interface Unit (DIU 200) 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.
The DIU 200 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 200 communicates with an intelligent CEM reader over
a single pair RS485 cable. 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).
As an added benefit, the DIU 200 monitors the status of all standard door
monitoring inputs; inputs on an intelligent CEM reader are free for use as general
purpose inputs.
