Impact of Network Technology Sunsets on AlarmAgent WRTUs

Posted on Fri, Dec 11, 2020 @ 11:21 AM

We all know technology changes quickly. How many cell phones have you had in the last decade? Sometimes that change collides with Raco’s commitment to delivering durable products that last decades. We still have autodialers installed that were sold in the 1980s! While staying ahead of that technology curve Raco has remained committed to supporting all of the installed units out in the field. For the past few years have shipped with the latest LTE wireless technology. There are many benefits to the new technology, but many units still remain on legacy technology. If it ain’t broke, don’t fix it, after all.  OK, so what is happening? Key Raco network partners are now publicly committed that they will retire the legacy CDMA and 3G wireless networks in January and February of 2022, respectively. See details below. (more…)...

Case Study: Texas Town Benefits From

Posted on Fri, Feb 11, 2011 @ 3:12 PM

City officials in Midlothian, a fast-growing city in Texas, knew that accurate, efficient monitoring of its 12 pump stations was critical to keeping its water infrastructure running smoothly. To improve the functionality and efficiency of its pump monitoring capabilities, the city added RACO’s, a wireless, web-based system that provides on-demand pump monitoring and alarm detection for water and wastewater treatment plants. Now, plant personnel can monitor flow rates, start rates, water levels and more to ensure that pumps are operating at their best. also notifies plant operators of any pump inefficiencies before serious damage or back-ups can occur. The system already has proved valuable. Recently, a maintenance worker was notified of a pump inefficiency. Upon investigation, he discovered the pump was clogged with a mop head, but because of the quick notification, he was able resolve the problem before any major issues could occur. has helped maintenance personnel keep the pumps performing at their highest efficiency, which saves the city money and reduces energy use. Midlothian officials plan to continue using in the future—city regulations now require any new pump stations to use to ensu... Continue Reading

Know Your Options: Communication Platforms for Remote Monitoring Systems

Posted on Mon, Jan 24, 2011 @ 8:44 AM

Remote terminal units, or RTUs, allow municipalities, utilities and manufacturers to remotely monitor facilities and equipment and communicate data or alarms to personnel via phone, fax, pager, cell phone, email or voicemail. Traditionally, RTUs transmit data or alarm notifications via landline telephone, but more options are now available. They include: • Conventional landline: The conventional landline option is the simplest—an RTU transmits data via the landline network to the predetermined device. • Cellular networks: The prevalence of cell phones means the RTU can transmit through a cellular network to the landline network. • The Internet provides a third transmission option—machine-to-machine, or M2M. An RTU transmits data packets via an M2M network to the cellular and landline networks, which transfer the information through an M2M service provider gateway to the RTU manufacturer’s website. A notification is then sent to notify personnel that they can access data through the manufacturer’s website. Consider your facility’s remote monitoring needs when choosing a communication platform. Systems that require frequent, high-volume data transmission are best suited to cellular and landline networks, since they allow unlimited transmission and data l... Continue Reading
