The NX-586E can store up to four (4) NetworX alarm panel configurations -- panel only, no modules -- within its own nonvolatile memory. These files can be created using the DL900 software (1.13 or later) without a panel attached (power must still be supplied). The files can also be created using the installer program mode on any existing NetworX panel without the need for any computer. The files stored on the Direct Connect unit can be transferred to any panel of the same type or read by the DL900 software for reviewing, editing and archiving purposes. GE Interlogix.
