The DRI controls all aspects of a secure door or barrier that requires entry and exit using up to two card readers. This includes support for an entry reader, exit reader, a door strike to lock and unlock the door, and door contact to detect the door’s position.

The DRI allows the on-board inputs to be supervised individually. This ensures, for example, wire tampering is reported to the system by generating an ALARM message when detected.

The DRI provides three programmable auxiliary input connections for the monitoring of system aspects. This may include the monitoring of a cabinet door, duress switch, or PIR motion sensors.

The DRI also provides an auxiliary output. This allows a buzzer, strobe light or similar device to be connected and can be configured to trigger when security is breached. By using the latest flash technology, the DRI is fully updateable, and can be easily programmed via the host system to operate in its intended mode.

This leading-edge technology allows the DRI to be reprogrammed or reconfigured and used in conjunction with other Siemens security products, providing a complete and fully expandable access control solution. The DRI has been carefully engineered so that it can be easily mounted in any appropriate location.

This includes the ability to conveniently install the DRI near the door which it controls, or can just as easily be installed centrally in the same cabinet as the controller.
