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.
