OVERVIEW
The Door Interface Unit (DIU 210) 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 210 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 210 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 210 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 210 is supplied in a steel enclosure complete with power supply backplane and
an output for an additional door holder.
