Available for Siemens modular fire systems, Acend™ Intelligent delivers smart and autonomous protection through advanced addressable notification. Featuring real-time device visibility, automated self-testing DFTtechnology™, and built-in ISOtechnology™ Class X isolation, it ensures smarter testing, fewer disruptions, and maximum uptime—anytime, anywhere.
Intelligence. Survivability. Dependability. This is ACEND Intelligent.
A product line built for demands of the modern day. These addressable notification appliances are highly versatile, which allows for streamlining signaling circuit designs with unmatched reliability.
Why Does Addressability Matter?
With self-testing, you can simplify your yearly testing procedures, allowing you to better optimize your already stretched-thin resources. Increase building safety by scheduling regular and automatic testing of your appliances, ensuring signal operability. And with Disturbance-Free Testing (DFT), you can even have regular discreet self-testing for around-the-clock occupied buildings, such as hospitals, without worrying of waking the patients.
ISO Technology for Class-X Complete Systems

One novel aspect of Acend Intelligent is that it comes with built-in isolators. This revolutionary application of ISOtechnology means any class A circuits become class X automatically with Acend Intelligent, boosting fire system resilience and occupant safety without the additional cost of external isolators. Acend Intelligent – Elevating your protection, the smarter way.
Self Testing - What's That All About?

Featuring Siemens exclusive DFTtechnology (Disturbance-Free Testing), Acend Intelligent
appliances let you run appliance self testing as often as needed, without interrupting daily
operations. And with scheduling, you can automate your tests – automatic, accurate and Dependable – for full system confidence at all times.
With multiple self-tests available, you’re able to choose the self-test that best suit your needs.
Note that at the time of our initial launch, speakers* and speaker-strobes will have fewer
self-test options than the other appliances.
Real-time connectivity via Building X Fire Apps
Acend Intelligent devices connect seamlessly to the cloud via Building X Fire Apps, giving you full visibility into your fire safety system— anytime, anywhere. Whether on-site or remote, you’ll know your system is performing at its best and ready to respond. Act faster and smarter with cloud connectivity.

With remote access, you can test loops or individual devices, monitor system health in real time, and instantly access diagnostics and test reports. If an issue arises, pinpoint its location and resolve it quickly—keeping your operations safe, compliant, and uninterrupted.
Benefits of the Building X Fire Apps include:
Remote command and control for streamlined testing, reduced maintenance effort, and assured compliance
On-demand, downloadable site reports for easy record keeping and compliance tracking
Push notifications for critical site alerts in real time
