With 16 serial ports, integrated local audiovisual notification, two separate NICs, powerful alarm collection, and versatile alarm reporting via SNMP Trap and email, the NetGuardian-16S can handle any alarm monitoring need.


Key Features

  • 8 analog alarms
  • 8 control relays
  • 32 discrete alarms
  • Web interface: monitor your network without a master

The NetGuardian-16S is based on the proven hardware and software of the popular 832A, providing you with greatly expanded functionality - including a 16-port terminal server, an integrated Building Status unit, and more.

This high-capacity SNMP RTU incorporates many functions that previously required several separate units. But, the NetGuardian-16S occupies only 1 RU on any standard 19" or 23" equipment rack, freeing valuable rack space for revenue-generating gear.

With the NetGuardian-16S, you can:

  • Connect multiple concurrent users via Telnet over LAN to up to 16 serial devices
  • Notify on-site personal of Critical, Major, and Minor alarms via the integrated audiovisual Building Status Unit
  • Connect the NetGuardian-16S to two separate Ethernet
  • connections, each with its own IP address
  • Monitor 32 discrete alarms, 32 ping alarms, and 8 analog alarms
  • Control remote site equipment via 8 control relays
  • Monitor your remote site from anywhere using the NetGuardian-16S’s built-in Web Browser Interface
  • Automatically send pager and email alarm notifications 24 hours a day, seven days a week
