Core Features of Remote Monitoring Systems
How Remote Monitoring Systems Work for Emergency Power Equipment
Data Points Monitored by Remote Systems
Remote monitoring systems track a wide range of critical metrics, including fuel levels, engine performance, electrical outputs, battery health, environmental conditions, and site security. These systems measure engine parameters like oil pressure, temperature, runtime hours, and RPM, while also monitoring electrical outputs such as voltage, power, and UPS loads. Battery performance is assessed at both the string and individual cell levels. Additionally, they keep an eye on ambient conditions and key components like capacitors, fans, and air filters. For security, door sensors and transfer switch indicators are monitored.
Advanced systems go a step further, incorporating theft alarms for fuel, precise voltage diagnostics for individual battery cells, and environmental sensors to prevent overheating. The level of detail in these measurements is crucial. In fact, integrating remote monitoring with predictive analytics can slash downtime from part failures by as much as 75%. Some systems even update telemetry every 15 minutes, offering near real-time insights.
All these metrics play a vital role in the monitoring process described below.
How the Monitoring Process Works
Generators and UPS systems are equipped with sensors that collect real-time data. This information is transmitted through 4G/LTE, Wi-Fi, satellite, or LAN connections to cloud-based platforms. Predictive analytics then analyze the data to detect potential failures. Users can access site trends and statuses on mobile apps or web dashboards, while alerts are sent via SMS, email, or voice calls when any parameter crosses a set threshold. Technicians can remotely clear faults or test transfer switches when necessary.
To ensure uninterrupted monitoring, these systems often include internal battery backups. This feature enables them to continue operating and sending alerts even during primary power outages. For example, in 2023, Kaiser Permanente's Senior Manager, Bitsy Bernat, shared how their monitoring system helped prevent a major issue by identifying a temperature spike in a facility:
"The service has definitely quickly deployed field technicians. At one of our sites, the temperature in the room was rising. Because we received a notification, we were able to get an engineer dispatched to the site to the HVAC problem. Had we not done that, we might have ended up with a UPS failure."

This seamless data transmission and alert system naturally demand robust security and reliability measures, which are covered next.
Data Security and System Reliability
The effectiveness of any monitoring system hinges on the strength of its data security measures.
To mitigate risks, data is transmitted outbound using SSL-encrypted protocols like SMTP, eliminating the need for inbound firewall access. Cellular or satellite connectivity ensures isolation, while multi-level authentication and detailed access logs limit system access. Redundant communication paths and backup hardware further enhance reliability, reducing generator fail-to-start incidents by up to 95%.
Some providers take extra precautions by designing systems that are read-only, removing the ability for remote control of critical power infrastructure. When evaluating providers, it’s wise to prioritize systems that use outbound-only data transfers and offer two-step verification for web-based access. These measures ensure both security and operational reliability.
Benefits of Remote Monitoring for Emergency Power
Preventive Maintenance and Less Downtime
Remote monitoring keeps a close eye on the health of essential components like batteries, fans, and capacitors. Instead of sticking to a rigid replacement schedule, it allows for swapping parts based on their actual condition, reducing unnecessary maintenance.
Here's a striking statistic: about 90% of failure-to-start events in emergency power systems stem from issues with batteries, fuel, block heaters, or alarms. For example, if a battery charger fails, the voltage can dip below the 11.0 V cranking threshold in just one day. With remote monitoring, this issue can be flagged a full day in advance, giving you time to act.
Jarrett, Founder and Vice President of OmniMetrix LLC, highlights the importance of addressing these common issues:
"90% of failure-to-start events can be attributed to these four situations [battery, fuel, block heaters, and ignored alarms]. Then, prompt attention can prevent 90% of would-be emergency power system failures."
By catching these problems early, remote monitoring ensures faster fault detection and smoother resolutions.
Quicker Problem Detection and Response
Imagine getting instant alerts - via SMS, email, or phone - about faults in your emergency power system, even at unmanned sites. These alerts provide specific fault codes, enabling technicians to show up prepared and ready to fix the issue.
Remote monitoring goes a step further by distinguishing between minor glitches and serious faults. This means operators can remotely diagnose and even reset issues when necessary. According to Jarrett:
"In the 50% of alarms that are simply transients, the owner's standby power can be recovered quickly via this remote service attention."
Additionally, these systems monitor utility power quality, helping detect if a generator is running unnecessarily due to erratic voltage instead of an actual outage. This prevents excessive fuel use and reduces wear and tear on the engine.
Lower Costs and Better Operations
Remote monitoring doesn't just make problem-solving faster - it also saves money and improves overall system performance.
By catching potential failures early, predictive analytics can cut equipment downtime from part failures by up to 75%. Fewer unnecessary service calls mean lower costs, and technicians can arrive with the right parts, boosting first-time fix rates and reducing labor hours. Addressing small issues quickly also avoids expensive repairs down the line.
Automated reporting tools track fuel usage, runtime, and emissions, ensuring compliance with EPA and state regulations. This helps facilities avoid hefty fines while streamlining operations for multi-generator setups through centralized dashboards. Some providers, like Eaton, even offer free 90-day trials for services like PredictPulse, giving facilities a chance to test the technology before committing.
Step-by-Step Guide to Installing Remote Monitoring
If you're looking to harness the benefits of real-time data and fault detection for your emergency power systems, this step-by-step guide will help you set up a remote monitoring system tailored to your needs.
Evaluating Your Current Equipment and Requirements
Start by taking stock of all your equipment - backup generators, UPS batteries, fuel tanks, and HVAC units. Check if your devices support MODBUS or SNMP outputs, as these protocols are key for detailed diagnostics. For example, MODBUS can provide accurate fuel level readings without needing extra sensors.
Next, determine the number of inputs you'll need. Discrete inputs handle binary alarms (like on/off statuses), while analog inputs are used for continuous data like voltage, temperature, or fuel levels. Using a standardized survey worksheet can help you organize this information.
Andrew Erickson, an Application Engineer at DPS Telecom, offers this advice:
"First, decide what you want to monitor - generator, temperature, door sensors - and then we'll add those up. The total determines which RTU you need."
Don't forget to assess your site's physical setup. Note the available power sources (e.g., –48V DC or +24V DC), mounting options (rack, DIN rail, or wall), and connectivity (LAN or cellular). It's wise to plan for a 15–20% capacity margin to accommodate future needs.
Once you've mapped out your equipment and input requirements, you're ready to move on to selecting the right hardware and network solutions.
Selecting Hardware and Network Connections
For smaller sites, look for RTUs with around 16 discrete inputs and 6 analog inputs. Larger setups may require RTUs with 64 discrete and 8 analog inputs. Make sure the hardware supports analog sensors (0–5 VDC or 4–20 mA) and digital protocols like MODBUS via RS-485.
Whenever possible, prioritize wired Ethernet connections. According to Andrew Erickson:
"Opt for wired connections over wireless when possible, as they typically offer greater reliability and performance. Network security is another factor that drives virtually all of my clients to wired connections."
For remote locations without wired infrastructure, cellular connectivity is a solid alternative. Many RTUs are equipped to automatically switch to cellular modems if the primary LAN connection fails, ensuring secure data transmission. If you're ordering generators, make sure the manufacturer includes the necessary hardware or software for MODBUS, as some opt for proprietary cloud services instead.
Once your hardware and network are in place, it's time to configure alerts and dashboards to complete your system.
Setting Up Alerts, Dashboards, and Response Procedures
Define high and low thresholds for each sensor, and set up multi-channel notifications through email, SMS, or phone. Include an acknowledgment system to ensure alerts escalate if they're not addressed.
For operations managing more than 10 remote sites, consider using a master station. This consolidates alarms into one interface, eliminating the need to monitor individual RTU webpages. Your dashboard should display real-time statuses, geographic maps for tracking sites, and historical trend graphs to analyze patterns. Implement multi-level security so team members only see the alerts and data relevant to their roles or regions.
Finally, review alarm data regularly to identify and resolve recurring nuisance alarms. This step helps reduce alarm fatigue and ensures your team stays focused on critical issues.
