Built-In Isolation Technology Feature Now Standard on All Siemens Fire Safety Devices and Detectors

Saves Time and Money, Improves Survivability and Serviceability

  • Secure, maximum protection against short circuits for a more reliable life safety system
  • Flexible, on-demand isolation enables easy system expansion and modification
  • Addressable isolation makes troubleshooting faster and easier

Siemens is the first and only UL fire product manufacturer to provide built-in isolation in all its major fire system devices at no extra cost. The ISOtechnology™ feature is built-in isolation technology that allows the system to continue to operate normally, even signaling the exact location of a short on the display and sounding an alarm in case of a detected emergency. Now standard on all Siemens fire safety devices and detectors, this feature provides real-time wire fault location reporting, reduced maintenance, and increased protection against short circuits for a more reliable life safety system.


Despite the critical importance of a fire safety system’s performance in protecting building occupants in the event of a fire or other building emergency, system designs often end up being based on the lowest possible installation and product cost. Wiring shorts or open circuits can render fire systems inoperable or significantly limit detection of fire events and therefore, potentially limit the ability to notify and evacuate building occupants. 


“You shouldn’t have to pay a premium price for the best possible fire safety system performance. Protection matters – that is why we developed ISOtechnology – which includes short circuit isolation standard in every addressable device at no additional cost,” says Brian O’Mahoney, Segment Head for Fire Safety, Siemens Smart Infrastructure USA. “Part of what makes the ISOtechnology feature an industry game changer is that it allows engineers to provide Class X isolation, where each section of wire between every device is isolated and identifiable. This gives engineers design flexibility and significantly increases fire system performance, while dramatically reducing troubleshooting times by pinpointing signaling line circuit wiring problems – all of which reduces the overall project cost and improves life safety.”


Traditionally, many manufacturers require placing isolators between devices to “isolate” that section of wire. However, Siemens’ isolation technology that is built into its devices helps alleviate the need to install so many fire devices. This eliminates the need for extra labor, backboxes, and conduit, making the project overall more efficient. For instance, if 100 detectors were specified for a project, they would be installed plus 200 additional isolator modules, 200 backboxes and countless conduit – which more than doubles the materials’ cost and extends the project installation timeline.  By contrast, only 100 detectors with the ISOtechnology feature would need to be installed to provide the same level of isolation.


Having fewer devices makes serviceability easier and more efficient. The standard loop configuration also increases functionality and survivability, with a short in one zone not affecting other zones or shutting down the entire system. Addressable isolation allows service providers to troubleshoot faster, pinpointing the exact location of a problem, avoiding disruptive testing, and decreasing business downtime.


In addition to not having to specify separate isolators, using less wiring and conduit also reduces material and related labor costs. And the flexible on-demand isolation allows end users to easily expand and modify their system whenever needed.
