 Last WeekWe took a closer look at our monitoring system—how it works, why it works the way it does, and we dispelled a few common myths along the way. If you missed it, you can catch up here AFAM Monitoring System. This Week: Next Generation CTUA couple of weeks ago we shared that we’ve begun developing a next-generation version of our CTU monitoring device. This week, we’re excited to give you a deeper look at what’s underway. Next Generation CTUEarlier this year, we quietly kicked off a ground-up redesign of our CTU hardware. Our current CTU has served the industry for more than a decade, evolving through multiple updates and still outperforming alternatives. However, there are new features and services we want to deliver that the current design simply can’t support. This redesign lays the foundation for those capabilities—both for today and for the future. Be rest assured though, everything that the current CTU provides such as in panel installation and native IoT Detector Level information capture will be carried forward. We're not going to remove any existing functionality, we're going to add to it. A Common PlatformRight now, we manufacture two CTU variants, chosen based on whether the device will be installed inside a panel or not. The new CTU will be built as a single common platform, with an optional secondary board (added during manufacturing) to meet specific installation requirements. This gives us far more flexibility, makes future feature expansion easier, and even opens the door to potential use in new markets here and overseas. Bluetooth ConnectivityThe next-generation CTU includes built-in Bluetooth. One major use will be enabling authorised users to connect via the AFAM AlarmTech App for diagnostics and commissioning while on-site. This will mean guided commissioning prompts, clear indications of what’s correct or incorrect, and far less reliance on manuals, prior knowledge, or interpreting LEDs on the unit. Processor & MemoryThis new CTU isn’t just faster—it’s dramatically faster.
This leap in capability allows far more processing to happen directly on the device, which will be crucial for the new services we’re planning. Inputs & OutputsAs with the current CTU, the new device will include four versatile inputs. (If you missed our article on how those inputs work, you can read it here: CTU Additional Inputs) The next-gen CTU will also feature two outputs, allowing the device not just to monitor equipment but to activate it when required. Advanced Battery ManagementWe’ve designed the new CTU around a modern, commercial-grade battery management system. Battery management technology has advanced significantly since our current model was introduced, and this upgrade will improve charging, monitoring, and overall battery lifespan. When Will It Be Available?We’re still in the prototyping phase. While we’d love to release it this year, that won’t be possible. Hardware development takes time, and our best estimate is that the CTU will be ready sometime early to mid next year. What Else Could It Do?There’s plenty we haven’t revealed yet—and we’d love your input. If there’s something you’d like the new CTU to be capable of, let us know. We may already be working on it, or it might be something we can still build in. We can’t promise every idea will make it, but we’re listening. Coming Next WeekWe’ve got some news to share—and a few interesting updates you won’t want to miss.
 Last WeekWe explored a range of well-known—and not-so-well-known—features in Solomon designed to make life easier for service agents.

This Week: Monitoring SystemThis week, we’re lifting the lid on our monitoring system—how it works, what makes it secure, robust, and reliable, and a few statistics and things that might surprise you. Monitoring System The diagram above shows where the monitoring system fits within the overall solution. It’s the component that CTUs communicate with, and it, in turn, communicates with FENZ, fire alarm service agents, and building owners. It does much more behind the scenes, but at its core, that’s its purpose. Distributed for ResilienceThe monitoring system is built from multiple services and applications running across several providers and data centres throughout New Zealand—primarily in Christchurch and Auckland. We’ve intentionally designed it so we’re never dependent on any single hosting location or provider. All CTUs are aware of all services nationwide and can communicate with any of them. If one provider or location experiences an issue, CTUs automatically and seamlessly switch to an alternative service—no manual intervention, and no interruption. Fire Service (FENZ) MessagesThere are two common misconceptions about how we communicate with FENZ:
FENZ operates multiple services across different NZ locations, and we have dedicated secure connections to all of them. Messaging, Lots of MessagingBeyond FENZ notifications, the monitoring system also powers our advanced rules engine, which determines who needs to be notified, when, and via which channel as per their preference. It’s a busy part of the system. In an average month, we deliver over 800,000 messages to service agents and building owners—and in peak months, that number exceeds 1 million. Urban vs Rural MonitoringWe monitor buildings nationwide, and the monitoring system is designed so we can provide coverage anywhere in New Zealand with cellular service. What surprises some people is that urban and rural monitoring are handled identically. Whether it’s a building in the Auckland CBD or a ski lodge on a mountaintop, the process and technology are exactly the same. Monitoring the Monitoring SystemBecause the monitoring system is mission-critical, we use several independent services to continuously track its performance and alert our team to any potential issues. We also follow IT industry best practice for support and maintenance, and undergo annual independent audits to ensure our policies and processes are both appropriate and consistently followed. What Happens When there are Issues?While the system is designed for maximum reliability, no complex IT system is immune to issues. Thanks to our distributed architecture, most failures are handled automatically and transparently—often without users even noticing. After every incident, regardless of impact, we follow the same three-question process:
This disciplined approach ensures we continue to improve and strengthen the system over time. Coming Next WeekA few weeks ago, we mentioned our project to redesign and modernise the CTU hardware. Next week, we’ll share more about that project and some of the exciting capabilities the next-generation CTU will bring.
 Last WeekWe took a break from our usual product updates to share some exciting AFAM news — including recruiting an Auckland-based BDM and opening a new Auckland office! If you missed it, you can catch up here AFAM News & Updates. This Week: Backup Power SourcesThis week we’re talking about backup power sources for the CTU and connected devices. It might not be the flashiest topic, but it’s one of the most important — because getting it wrong can cause real headaches later on. Backup Power OptionsWe currently support two types of backup power sources:
The best option depends on your installation type and how many systems are connected. SLA Batteries Invented in the 1970s, the Sealed Lead Acid (SLA) battery became the standard for reliability and consistency. It uses lead plates and an acid-based liquid or gel to store and release charge. Traditional lead acid batteries as a technology were invented in 1859. Super Capacitors Super Capacitors work similarly to normal capacitors but are far more efficient at storing and releasing energy. They excel at delivering high currents when needed and aren’t affected by temperature in the same way as SLA batteries. Battery vs Super Capacitor - Which to Use?We generally use Super Capacitors when the CTU is installed in-panel and not connected to any secondary system. For all other installations, a battery is required. The required battery size depends on the number of connected systems — full details are in our installation instructions. If you’re unsure, our support team is always happy to help. Battery Quality MattersNot all batteries are created equal. Even if two look the same, their internal build quality can differ significantly. When purchasing batteries, stick with reputable brands and suppliers. Check the warranty period — shorter warranties often indicate cheaper, less reliable batteries. While budget options can seem tempting, they often cost more in the long run. 6 Volt BatteriesPreviously, some in-panel installations used two 6V batteries connected in series. However, when the original manufacturer discontinued these batteries, we were unable to find an alternative that met our performance standards. We now supply a single 12V 2.9Ah battery, which comfortably meets all backup requirements for new installations. For existing systems, we can still supply 6V replacements in the same form factor, but these now carry a 6-month warranty, reflecting the warranty provided by our supplier. If you have any questions, our support team can help. Battery vs Super Capacitor Confusion - Avoid the Mix UpAs we mentioned in a recent Tips & Tricks newsletter, the CTU can use either a battery or a Super Capacitor — never both at the same time. The Super Capacitor connector includes a detection pin that tells the CTU what’s connected. If both are plugged in, the battery can overcharge and be damaged. Connecting to the wrong port won’t harm the CTU, but it can leave the system without a proper backup. When in doubt, check your connectors or contact our support team — they’ll help ensure everything’s set up correctly. Coming Next WeekNext week, we’re diving into Solomon and focusing on features for Service Agents — including how to access them both in the office and on-site (even after hours). We’ll show you what’s available and how these features can make your work smoother and more efficient.
