DIU 220
Power over Ethernet Door Interface Unit
OVERVIEW
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.
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
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).
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.
