NOTIFIERby Honeywell (NYSE: HON) announce'dtoday its new commercial wireless fire alarm solution to protect challengingapplications and high-cost installations, as well as building expansions. The Smart WirelessIntegrated Fire Technology (SWIFT) detectors andmodules seamlessly integrate with new and existing NOTIFIER fire alarm systems.
Using a Class A, mesh networkwhere every device acts as a repeater with redundant path communication, SWIFTsystems are robust and self-healing, making them a highly-reliable firedetection solution. Once a mesh network is formed, a restructuringautomatically occurs to find the strongest paths within the network. Uniquemesh IDs in each SWIFT network prevents miscommunication with other devices andinherent frequency hopping prevents system interference.
Theelimination of wires leads to more flexibility in installation, reducing the costof running wire through concrete walls/ceilings or areas where materials suchas asbestos are a concern. Wireless technology also benefits the numerousinstallations where mounting detectors is extremely challenging.
"Hybridapplications where both wired and wireless detection can be used are perfectfor SWIFT," said Mike Lynch, vice president-engineering for Honeywell FireSystems. "If you've got an ornate interior that makes detector placement difficult,or places like parking garages where drilling through concrete is costly, SWIFTis the ideal solution."
Theinitial launch of SWIFT devices will include photoelectric, photo/thermal,standard heat, and rate-of-rise heat detectors, plus a monitor module. A systemcan have any combination of up to 50 devices per wireless gateway, includingthe gateway itself and user interface driver. Spacing of SWIFT devices should follow NFPA guidelines for the application.In an average environment, SWIFT devices can be placed approximately 50 feetfrom the gateway and from each other. Various factors such as physical barriersand other radio transmissions can affect signal strength, therefore a sitesurvey before installation is recommended. The SWIFT system offers a sitesurvey procedure, which allows an installer to preview a site for wirelessviability before a system is purchased.
