We try to stay on top of products that would appeal to the custom installer, and Furman's new line of "SmartSequencers" are a great addition to its Contractor Series products. There are two new products, the CN-1800S (15 amp capacity) and the CN-2400S (20 amp capacity). These SmartSequencers are designed for commercial A/V installers and they combine AC power distribution, protection, filtration, and sequential system power on/off. They also offer an optional compatibility with Panamax/Furman's BlueBOLT hosted remote power and energy management platform. The CN-1800S and CN-2400S feature Furman's SmartSequencing technology, which allows large and complex A/V systems to be powered on and off safely with the simple press of a button or turn of a key, even by nontechnical personnel. The SmartSequencer's bidirectional communications between installed units enables a primary unit to control and sequence multiple secondary units, ensuring multizone electronic systems are powered on and off safely and dependably from a single control point across an entire installation. Units can be connected via current loop at runs of more than 1,000 feet, with backwards compatibility with Furman's legacy sequencers and/or third-party products.

Providing robust control options, the CN-1800S and CN-2400S are equipped with RS-232 ports and command sets for PC control or integration with control systems. An optional RS-232-to-Ethernet adapter, sold separately, adds full IP-addressability to the unit so it may be controlled, programmed, and monitored via telnet, or from any Web-enabled device with Panamax/Furman's cloud-based BlueBOLT platform. The 1RU, 120VAC rack-mount units feature eight rear-panel outlets, plus one front-panel convenience outlet, in four duplex outlet banks. Three of the banks are capable of being sequenced on and off with an adjustable delay. All outlets provide clean, safe power with Furman's SMP, EVS, and LiFT protection and filtration technologies.

"The CN-1800S and CN-2400S caused quite a stir during their debut at InfoComm last year, and we are excited to say that these Contractor Series SmartSequencers are now available for commercial A/V installers. Packed with advanced features including our SmartSequencing platform, BlueBOLT compatibility, and our proven protection and filtration technologies, the CN-1800S and CN-2400S are ready to tackle installations of any size or complexity."

- Dave Keller, senior vice president of sales and marketing for Panamax/Furman

The CN-1800S and CN-2400S are available at MSRPs of $499.95 and $549.95 respectively. The RS-232-to-Ethernet adapter (model # BB-RS232) will be available later this year and will retail for $249.95. More information on the Contractor Series is available at www.furmancontractor.com.
