For land mobile radio (LMR) systems, public safety answering points (PSAPs), and fire and police stations, reliable communications is more than a goal. It’s a necessity. Infrastructure for emergency communications must remain operational in conditions that cause other systems to fail.At SEL, we provide public safety agencies with ultra-reliable technology that underpins the performance of their mission. Our devices, solutions, and support not only keep critical systems online, but also reduce maintenance and operational expenses so you can make the most of the public investment in your services. With your systems running reliably and automatically, you can keep the focus on your mission.
Enhance Resilience With Continuous Availability
For over 40 years, SEL has provided ultra-reliable solutions for mission-critical public infrastructure systems that demand continuous availability. We build public safety solutions on the capabilities of our devices, which operate reliably in harsh conditions, enduring temperature ranges as wide as –40° to +85°C (–40° to +185°F) and exceeding industry standards for resistance to conditions such as humidity, corrosion, shock, electric stress, and electromagnetic interference.Explore our key offerings:
Wide-area networking and remote-site monitoring solutions that are flexible and scalable, offering support for analog and digital I/O and both time-division multiplexing and Ethernet transport.
Rugged industrial computers that withstand harsh conditions (such as extreme temperatures and electromagnetic interference), feature a fanless design, require virtually no maintenance, and have a lifespan measured in decades.
Satellite-synchronized network clocks that reliably synchronize critical communications, such as simulcast systems, even in the event of a GPS disruption.
Microgrid control systems that seamlessly manage the transition to emergency power and back to grid power, ensuring that critical facilities won’t lose power.
Data from decades of field performance verify that SEL devices minimize the need for repairs and replacements, making your systems more reliable and lowering the lifetime cost of ownership.
Project Highlight
Duke Energy Improves Resiliency With a Simplified Microgrid
See how Duke Energy implemented a microgrid that reduces power outage costs and preserves a local fire station’s ability to respond during the hurricane season.
“The customer had seen rather complex microgrid control architectures and had a real desire to keep this simple. Using a simple, easy-to-use HMI and the inherent capabilities of SEL devices, we were able to help them realize that vision.”
Reliable Emergency Radio Becomes a Community Effort
To protect first responders and better serve the public, Whitman County Emergency Management (WCEM) looked to SEL for help developing a more reliable LMR solution.
“Audio quality is everything. It’s not the important thing. It’s the only thing. At the end of the day, my success or failure is entirely measured by the quality of audio that got through the air.”
Steve KrigbaumEmergency Communications Manager
WCEM incorporated SEL precise timing, remote monitoring, cybersecure networking, and rugged computing into their system, and almost immediately, the results were positive.
