How to Select a Remote Network Alarm Monitoring System
The Critical Alarm Enunciator provides local audible and visible notification of three battery level alarms and three discrete alarms, and then relays alarms to your existing monitoring equipment.
Make sure your system supports these essential remote network alarm monitoring functions:
- Alarm collection and device management: Don't settle for a limited remote alarm network monitoring system. Get multiprotocol support for every monitoring device in your network, plus discrete alarms, analog alarms, ping alarms, and redundant path reporting.
- Alarm sorting and analysis: Make sense of alarm cascades with automatic intelligent alarm sorting, filtering, processing, and trend analysis.
- Alarm presentation and notification: Send detailed alarm descriptions and correction instructions to NOC and field techs via pager notifications and web interfaces.
Checklist: Remote Alarm Network Monitoring Essentials
Here's a handy checklist of essential remote alarm network monitoring features you should look for in your next system. Print this checklist out and use it to rate the systems you're evaluating. If a system can't meet these basic requirements, cross it off your list.
Critical alarm collection and device management functions
- Multiprotocol support for your existing devices: Make sure your next master system collects alarms from all your existing devices, including your older legacy gear. You can get rid of all your specialized consoles and monitor your network from one screen.
- Live analog monitoring: You can't adequately monitor battery levels, temperature, and humidity with one-threshold contact closures. Look for support for analog inputs, including live monitoring of actual analog values.
- Back-up dial-up reporting: Don't rely on your primary network to bring back alarms - if anything goes wrong with your transport, you'll lose your telemetry data just when you need it the most. Look for a system that supports dial-up alternate path reporting.
- Control relays: Many common site problems, from power outages to high temperature alarms, can be solved by quickly turning on a generator or an air conditioner. Remote operation of site devices is the best way to eliminate unnecessary site visits and it's a lot faster than going in the truck.
- SNMP support and ping alarms: If you're responsible for both telecom and IP equipment, consolidate all your monitoring on one system.
Essential alarm sorting and analysis functions
- Alarm sorting: A large, complex network can create a cascade of alarms. Some are unimportant, but others are critical. Look for a system that can automatically sort and prioritize this flood of information for you.
- Custom combination alarms: A low battery isn't a serious problem, and neither is a failed generator - but they're pretty serious when the happen at the same time. Look for a system that can watch many different alarm inputs and spot critical alarm combinations.
- Root cause analysis: Finding the underlying cause between alarm cascades can take hours of patient detective work. Look for a system that can automatically correlate repeated combinations of alarms.
- Nuisance alarm filtering: Even the best NOC staff stops taking alarms seriously if they're bombarded with status alerts, oscillating conditions, and unimportant alarms. Look for a system that filters these out.
- History and trend analysis: Identify problem areas and eliminate recurring problems with a system that keeps a complete alarm history that's exportable for trend analysis.
Key alarm presentation and notification functions
- Detailed alarm notifications: Summary "major/minor" alarms don't give you enough information to make dispatch decisions. Look for a network alarm monitoring system that includes detailed diagnostic information in each alarm.
- Alarm correction instructions: Detailed instructions included in alarm notifications ensure that system operators, without extra training, will know precisely what to do and who to call if an alarm happens.
- Web interface: Everybody knows how to use a Web browser. A Web interface makes sure all your field techs can access your alarm system, from any computer from any location.
- Pager and e-mail notifications: Pager and e-mail notifications let your field techs respond to alarms while they're still in the field, speeding repairs and reducing windshield time. Look for a system with SMS support, which can send detailed alarm notifications to alpha pagers, cell phones, and PDAs.
This is just a checklist of basic monitoring functions.
