Upgrading Fire Safety: Integrating Modern Monitoring Systems with Legacy Infrastructure

By Andrew Erickson

November 21, 2024

It's challenging to integrate legacy systems with modern infrastructure. For municipalities, educational institutions, and large facilities, aging equipment frequently can't keep up with the demands of today's safety standards.

The result? Inefficiencies, increased risks, and rising frustration among the teams tasked with keeping these systems operational.

Let's look at a recent call between Digitize Support Engineer John Ermatinger and a client grappling with an outdated fire monitoring setup. Their conversation illustrates many common struggles (and solutions) for those managing legacy systems.

By examining this real-world scenario, we can better understand how modern systems, like the System 3505 Prism LX, can significantly improve your fire alarm monitoring.

The Problem: Legacy Systems Can't Keep Up Anymore

Old fire alarm systems were once (long ago) the cutting edge of safety technology. Over time, however, they have inevitably become a source of frustration for operators and a liability for those who depend on them.

"This is an old system that died earlier... This whole system is not capable. It's old technology," the client explained during his call with Digitize.

This sentiment is echoed across many organizations still relying on outdated configurations. Legacy systems, often designed for simpler infrastructures, fail to meet the demands of modern facilities, leaving gaps in monitoring and response.

The client shared how their setup once relied on a complex relay system to mimic features like battery backup and paging. However, as construction projects began, components of the system were left disconnected or replaced.

"We didn't hook it up into the PC boards at the time because they were about to do some construction," the client said. Over time, this patchwork approach led to declining performance.

What Happens When Legacy Systems Fail?

One significant issue with legacy systems is their inability to provide reliable and timely alerts. The client described several instances where their outdated system caused confusion during operations.

"When you get like an open circuit, you get one blast at a horn... but then like a six o'clock test would come in, which is three blasts, and it would hear those clicking, but nothing would come up on the display," they explained.

In a critical situation, such failures could lead to delayed responses, jeopardizing lives and property. Even routine issues like decoding errors can snowball into larger problems.

Digitize Engineer John noted, "If it mis-decodes a box as it's coming in, it will sound the system buzzer... and then it goes back to processing." While experienced technicians can troubleshoot these hiccups, the added downtime is a burden for teams already stretched thin.

Additionally, the physical wear and tear on outdated equipment adds another layer of frustration. "They kept pushing it. If they were getting mad, they had to keep resetting it," the client remarked about the repeated resets required to keep the system functional. Such frequent manual interventions are both a waste of time and prone to human error (and inattention and neglect).

The Challenge of Modernizing Without Overhauling

For many organizations, the cost of fully replacing a legacy system is prohibitive. This leaves them searching for ways to modernize incrementally - an approach that is usually far more difficult than you expect.

During the call, the client expressed concerns about the complexity of reconnecting their legacy system to newer components. "I think, since it was hooked up differently the last previous time... I have to find the existing wiring that's coming from the system that's buried in the wall somewhere," the client said.

You need something that will work with both old and new infrastructure.

John provided guidance on how to simplify this process: "If your circuit 1 is tied into the repeater bus for the other circuits, then all you need is the common negative off the 4 and 4, and either the LR or MR terminal output."

We're getting pretty deep into the tech here, obviously, which does remind us of the importance of having expert support to navigate any fire-alarm integration.

What is the Right Solution?

Now imagine a fire alarm monitoring system that integrates seamlessly with legacy setups while providing the benefits of modern technology. It would eliminate the need for constant manual resets, offer real-time alerts without delay, and ensure compatibility with a wide range of devices.

In this ideal scenario, system operators would no longer need to wrestle with outdated components or worry about gaps in coverage. Instead, they would have access to a reliable, centralized monitoring platform that simplifies operations and enhances safety.

That would allow teams to focus on proactive maintenance and response rather than troubleshooting.

As the client noted about his legacy equipment, "Clearly things happen when things go wrong, and this system never fails." A properly integrated system would extend this reliability across the entire fire alarm system.

Featured Central Alarm Management Platform: Prism LX

What options exist that meet our new definition of an ideal solution? Digitize has developed one that you can consider:

The System 3505 Prism LX is a fire alarm monitoring system designed to bridge the gap between legacy and modern infrastructure. With its ability to process mixed communication protocols, the Prism LX is uniquely positioned to help you manage older systems.

During the call, John highlighted the Prism's capabilities: "If you're taking either the LR or MR terminals off of your Form 4, coding 24 volts... that should work fine as far as decoding your boxes go."

This feature ensures compatibility with a variety of input sources, allowing organizations to integrate their existing components without costly replacements.

The Prism LX also offers advanced diagnostic tools that simplify maintenance and troubleshooting. As John explained while remotely diagnosing, "I tested the other five circuits just to see, and they also worked. So, I mean, the system itself is functional."

The Prism also supports remote monitoring and control, providing flexibility when you're managing multiple sites or undergoing construction.

This Call is a Real-World Success Story

The client's experience with Digitize illustrates the major positive impact of upgrading to a modern monitoring solution. Despite initial challenges, they expressed confidence in the system's performance and the support provided by Digitize engineers.

"I'm sure the police will be really happy when I bring it back in," the client said, speaking to the importance of reliable monitoring for public safety. With the Prism LX, they were able to address their system's shortcomings while retaining key components of their existing infrastructure.

What is Your Path Forward?

The transition from legacy to modern fire alarm systems doesn't have to be overwhelming. With solutions like the System 3505 Prism LX and the expert support of Digitize engineers, you can achieve multi-era technology integration, enhanced reliability, and long-term efficiency.
