Building Controls: Trane
Trane is now offering its Air-Fi™ wireless technology for building controls. The company reports that Air-Fi wireless replaces the need for wired building controls, allowing installations to be completed quickly with less disruption to occupants in existing buildings, while also providing greater reliability, simplified installation, and more flexibility as building spaces change.
Many building owners face challenges connected to maintenance and repair with traditional wired building controls systems, which fail when wires are cut, disconnected, or damaged. Air-Fi can help optimize a building’s performance with less risk, thanks to self-repairing mesh technology that features redundant signal paths to help prevent communication failures. Trane offers a typical 200-ft indoor signal range, with up to four times the number of paths, extending up to a half-mile when unobstructed for even greater levels of signal reliability.
Air-Fi is a ZigBee® Certified Building Automation solution, and the system is built on a platform that supports BACnet® open standards. This allows customers to integrate devices in the future when the building expands or changes. Trane Air-Fi wireless also conforms to the IEEE 802.15.4 standard, so customers get a wireless BAS communication system that reliably coexists with other wireless systems, including Bluetooth® and Wi-Fi® — without interference. Trane officials said there is no security risk with Air-Fi, which uses a separate, secure network from those used by a building’s IT system. Air-Fi secures building automation networks by the use of AES-128 encryption, keys, and device authentication.
