Safety Made Smart: ISOtechnologyTM from Siemens
  
Life safety today is top of mind for nearly everyone. There is a
certain level of trust that fire alarm systems continue to work within a
fire incident. With system survivability being a key concern to
regulators, building managers, and the public, Siemens has
developed systems that are designed to meet and exceed
regulations that protect people, property, and assets.
One of the most significant concerns, particularly in a large
multi-story building, is implementing a secure and fully functional fire
alarm system. Today, it is not uncommon to have power and data for
hundreds of fire alarm devices connected over a single pair of wires.
The concern is, if a fault occurs somewhere between the devices, the
zone and location of the device may no longer be known, or the
operation of that circuit reduced or possibly impaired. These
scenarios could allow an undetected catastrophic event to develop
within the space due to inoperable life safety devices.
ISOtechnologyTM eliminates this concern by utilizing Fault
Detection and built-in Isolation in each fire alarm device (i.e.,
detector, manual station, I/O modules, etc.). It identifies when a fault
has occurred, reports the type of fault, and isolates as required.
ISOtechnologyTM allows other devices on a common Data
Communication Link (DCL) loop to operate when a fault occurs. Fault
Isolation is one of the key requirements under the National Building
Code and CAN/ULC-S524, and Siemens is the first major
manufacturer to provide a system with built-in isolation in all major
devices.
ISOtechnologyTM has proven to be reliable and secure, but the
benefits go well beyond peace of mind concerning operational
efficiency. ISOtechnologyTM is also extremely easy to install as it
utilizes fewer devices, includes pinpoint wire-to-wire short
identification, and can be added into existing Siemens various
Control Units.
To learn more about ISOtechnologyTM, we spoke with Jeffry
Tondang, Product Manager at Siemens Canada.
Q: What are the benefits of having built-in isolation in Fire
Alarm devices?
With built-in isolation in fire alarm devices such as smoke/heat
detectors, manual stations, input/output modules, the traditional
isolator-only devices are no longer needed, and this comes with
several benefits. For example, less engineering work, fewer devices
(no isolator-only devices, backboxes, wiring, and associated labor)
This would provide lower system life-cycle costs over the life of the
system with savings in operational and maintenance costs.
