WIRELESS ALARM AUTODIALER APPLICATIONS & BENEFITS

By: Frank5 Smith5

Wireless alarm autodialers keep owners and personnel, responsible for industrial machinery and equipment, constantly up to date with equipment status and alarm reports from their entire fleet. By integrating the autodialer into the into the piece of monitored equipment, the unit is able to transmit data about the equipment to a monitoring website and then dispatch update notifications through email, SMS, pager or any other communication medium appropriate for the application. Wireless alarm autodialers have a variety of I/O (input/output) to accommodate different electrical interfaces or sensors on the equipment to be monitored. These include digital inputs which monitor any signal that is either on or off such as dry contacts (relays), TTL or other digital (on/off) voltage thresholds, and sometimes direct physical interface to remote aannunciators, such as those commonly used on standby generators. The autodialer can also measure analog signals, typically voltages or currents, and trigger alarm notifications if the monitored signals fall outside of a configured normal range. Finally, digital outputs in the form of output control relays are available on some models of wireless alarm autodialers. These outputs enable the autodialer to remotely control the piece of equipment it monitors. This remote control can be used to remotely start a genset, to turn a pump on or off, or just about anything else where a benefit is realized from remote control.
While digital inputs only detect two signal states, these two states can have different meanings depending on the application. Common digital input states include on or off, high or low, alarming or normal, and running or stopped. The meanings of these signals are arbitrary. It's the electrical signal level that is important to the RTU (remote telemetry unit) in its determination of status for the monitored digital signal. While the digital inputs on an alarm autodialer used for remote monitoring detect only two states, additional useful information can be derived from these signals over time. On a pump station a digital input is used to monitor when the pump is running or off. With statistical features, an advanced autodialer calculates the total pump on time, the number of times the pump turned on and off. Also, the duty cycles of the pump motors can all be tracked over timeframes such as the past day, week, month, year. Additionally the reporting features of a wireless alarm autodialer enable the user to export this data or run the statistics over a specific date range of interest, such as a reporting period mandated by a regulating body or a range used for service billing or auditing.
Analog inputs interpret electrical signals from sensors or transducers that provide a voltage or current which varies proportionately to the quantity of what the sensor is measuring. A good example is a fuel level sensor for a fuel tank. On a standby generator, a fuel level sensor is used to output an analog signal continuously sampled by the wireless autodialer. This analog signal tells the autodialer the fuel tank level and enables it to keep track of fuel burn rate. It can even estimate how many engine run hours are left before the generator runs out of fuel. In this case the genset fuel level acts like a generator hour meter in reverse, counting down how long the generator can run before it will need fuel. Since an autodialer notifies interested personnel whenever an important status change occurs, many wireless autodialer features can be combined to provide a form of closed loop feedback. As the generator runs and depletes the tank, once it reaches a certain fuel level, a fuel service can be notified that automatically dispatches a crew to refill the tank for the generator needing additional fuel. If the fuel level reaches a critically low level, a supervisor can be notified so an alternative fuel service can be called to refuel. The whole time while the genset is running, data acquisition of the fuel burn rates is stored by the system for reporting and later analysis of efficiency. This fuel efficiency data can be exported into a variety of formats enabling equipment owners to evaluate the performance of their equipment and spot trends before they become major problems.
Digital outputs provide a means to remotely control industrial equipment. These digital outputs are typically dry contacts or relays that can switch an electrical load on or off remotely. While most of the time the remote control features are used infrequently, there is no technical limitation to the number of times they can be used per day. A common use for a wireless autodialer's digital outputs is remote control of a landfill flare. In a landfill gas system the landfill flare used to burn Methane gas may need to be shutdown or restarted due to severe weather, or if a landfill gas to energy plant at the facility is coming online or going offline. Landfill operators are increasingly interested in their greenhouse gas emissions as they explore incentives for alternative energy programs. They may use data from flare shutdown reports in combination with other collected monitoring data to calculate carbon offsets, and finally the aggregation of data across all of their sites to validate carbon credits and total carbon footprint.
Industrial equipment owners and operators depend on continuous remote monitoring of their equipment to provide the best possible service at the lowest cost. Advanced wireless alarm autodialers provide key features to improve the efficiency of almost any industrial service depending on equipment. Now, thanks to improvements in wireless technology, an easy to install and low cost wireless monitoring system can be used to meet their needs.
Key features of the wireless alarm autodialer provide totally wireless operation. No phone lines are needed as is the case with conventional telephone autodialers. The web based monitoring system is powerful, capable of many reporting metrics of interest to equipment managers, but is also easy to use and install thanks to its design. An internal battery backup on the RTU (remote telemetry unit) enables operation during power outages in addition to notifying interested personnel about power loss at the site monitored. The system provides daily updates by email or text. It gives immediate notification of any alarms or events. Users can access the remote monitoring system from anywhere, be it a home, the office or any place with internet access. The web-based configuration features provide flexible options for the sensor and transducer setup, while the online reports and history files make exporting data for all the events and alarms a snap.
