I conducted a webinar on November 16, 2015, titled Powerful and Simple! Flexible Design with SBUS and Fiber Optic to provide an overview of the Silent Knight addressable SBUS devices and how they provide flexibility for a variety of applications. I also presented the SK-F485C SBUS to Fiber Optic converter. This product provides a solution to the high risk of lightning damage and ground faults that often occur with wire runs between buildings.
Thank you for those who were able to attend this webinar. There were excellent questions and comments and I would like to address some of them in this blog:
A popular question centered on cascade and daisy-chain wiring of multiple SBUS devices. SBUS devices are addressable and provide flexible wiring configurations. Daisy chain, T-Tapping, and Home Run wire configurations are all acceptable methods. The fire alarm control panel will properly annunciate and report trouble events if there is a wire break with any of these methods.
Another popular question related to wire type and distances. Specifications call out for wire to be from 14 AWG to 22 AWG with a possible distance up to 6,000 feet. Wire can be of any type that meets NEC 760 fire power limited fire protective signaling cable.
Lastly, questions and observations arose about the specifications of the fiber optic cable. The SK-F485C uses 62.5 micron multi mode fiber optic cable at 115.2K bits/second. Fiber connections are ST connectors and the cable distance is up to 1 mile (5,280 feet).

As 2014 comes to a close soon, December is the perfect time to look back over the last 12 months and check the pulse of our dynamic industry. Although it had its ups and downs, I think many of us can agree that this one is worth remembering.
Some of the biggest milestones I want to call your attention to include:
Growth in most segments
Although the year started off slow—because of a surprisingly severe winter across the nation—the construction market really took off beginning in April. As a result of that slow start, we’ve been enjoying an extended construction season, and that has helped lead the industry to a strong close to 2014. We saw above-market growth in most segments, and I expect the year to wind up exceeding our original forecasts.
Several new growth drivers
We’re experiencing double-digit growth in three main segments: emergency communication, advanced detection and modern central station communications. These trends are helping to grow the industry as a whole, and likely will continue through next year as well:
Emergency communication has become a huge boon for the fire alarm industry. These systems offer notification of any emergency, such as severe weather, harmful gas, terrorism and active shooters, and are growing in popularity for both new construction and existing buildings where a fire alarm system already exists.
Advanced detection requirements, which are cropping up in a growing number of states and municipalities, also are impacting fire alarm installation. For example, recent code changes require carbon monoxide and traditional smoke detection in many buildings, especially those in the hospitality, education, multi-family and healthcare industries.
Modern central station communications through IP and cellular are replacing the use of traditional POTS lines at an increasing rate. These alternative communication methods are helping grow this industry segment, which in-turn helps increase fire and life safety sales.
In 2014, we focused on several revolutionary technologies that are certainly milestones for our industry:
SK-FIRE-CO – offers a time and money-saving solution for the growing numbers of facilities where fire and CO detection are required. This combined detection unit has enabled our dealers to offer their customers a great solution for adding CO detection in their buildings where it’s now required.
SK-F485C Wire to Fiber Converter – enables new and existing Silent Knight systems to significantly increase the distance of wire runs between fire alarm control panels and remote SBUS devices (e.g., power supplies), while providing a boost in surge protection. SK-F485C is the first wire-to-fiber converter to be UL listed for a non-proprietary line of fire alarm systems and sold over-the-counter at Security Equipment Wholesalers nationwide.
HP1205UL and HP1210UL – Power Supplies from Honeywell Power deliver more DC power to CCTV cameras and their peripheral devices, while also speeding up installation and service calls and maximizing the survivability of system operations when a facility’s AC power is lost.
These advancements have allowed Silent Knight’s customers to enjoy substantial growth this year. Thank you for your part in our success. Together, we look forward to a fantastic 2015 and beyond.
