Reserve Your Seat TodayWhen you're planning your alarm monitoring, think about the future. You don't want to get locked into an alarm system that's inadequate for your future needs - but you don't want to spend too much for alarm capacity you won't immediately use, either.
The NetGuardian 832A remote telemetry unit expands its capacity as your needs change. Install a NetGuardian at your remote site now, and get exactly the right coverage for your current needs.
Then, as your remote site grows, you can extend your alarm monitoring capabilities by adding NetGuardian DX Expansion units. Each NetGuardian DX adds 48 more alarm points, and you can daisy-chain up to three NetGuardian DXs off each NetGuardian 832A base unit.
Unit | Capacity |
|---|---|
Base NG 832 | 32 |
1 DX | 80 |
2 DX | 128 |
3 DX | 176 |
The NetGuardian 832A is a full-featured remote telemetry unit. The NetGuardian supports 32 discrete alarms, 32 ping alarms, 8 analog inputs, 8 controls, and 8 serial reach-through ports. The optional NetGuardian Expansion Unit can expand the NetGuardian's discrete alarm capacity to 80, 128 or 176 discrete alarms. The NetGuardian reports to T/Mon NOC or to multiple SNMP managers - or you can use the NetGuardian's built-in Web Browser Interface and email alarm notification to monitor your remote site without a master.
