Common Applications for the NetGuardian 224A
The NetGuardian 224A reports alarms as SNMP traps over LAN and supports DCP polling over RS-232, RS-485 or
LAN. The NetGuardian 224A supports simultaneous SNMP and DCP operation.
The NetGuardian 224A supports both LAN and serial port connectivity. The LAN connection and serial port can be
used at the same time to support simultaneous SNMP and DCP alarm reporting. However, only one DCP channel
can be used, therefore the NetGuardian 224A cannot simultaneously report DCP over LAN and DCP over serial port
connection.
In addition to its 24 discrete input points, the NetGuardian 224A has 2 control relays, both form C, for user defined
NO/NC connections, 2 analogs, and dwire. The control relays allow network administrators to respond remotely to
threats to system integrity. Using the control relays, network administrators can turn on backup generators, open
doors and gates for emergency access, reboot equipment, exhaust fans, or perform other functions. The
NetGuardian 224A also allows you to reverse the logic state of the alarm on a point by point basis for discrete
alarms.
Another feature of the NetGuardian 224A is user-defined alarm qualification times. This will allow you to clearly
distinguish momentary status changes from serious problems.
