When the cost of running wire and conduit becomes prohibitive, wireless devices provide a cost-effective alternative to traditional wired devices. But the benefits of a wireless system go beyond cost savings--faster installation time, improved appearance, and ability to be installed with minimal physical impact on a structure can each be a critical factor.
SWIFT devices are closely integrated with ONYX panels. A SWIFT wireless gateway is connected to the FlashScan SLC loop of a current ONYX system, and supports a network of up to 49 wireless devices. Additional wireless gateways can be added to increase the number of wireless devices, with up to 4 gateways in the same radio space. SWIFT devices are individually programmed, annunciated, and controlled by the ONYX system. Detectors support all features of ONYX intelligent sensing, including adjustable alarm and pre-alarm settings, maintenance alert annunciations, cooperative detection options, and drift compensation. Wired and wireless devices are fully annunciated and controlled at the primary system display.
Wireless devices are in increasingly common use, but concerns about wireless fire alarm reliability are still a concern for ESDs, engineers, authorities, and customers.
SWIFT Wireless was designed to provide maximum reliability. The SWIFT system proprietary protocol uses supervised, redundant communication paths to insure that event data reaches the fire alarm control panel. Signal strength for each communication link is evaluated, and the initial system setup automatically incorporates a safe margin to insure that routine variations in the environment will not disrupt communications.
Proper installation is another critical factor in ensuring a robust, reliable wireless system. The SWIFT system includes tools for pre-qualifying a site and to determine that the signal strength of every link is well above minimum. SWIFT TOOLS, a suite of wireless tools that runs on a Windows® PC, supports sophisticated analysis of the health of a wireless network, providing technicians with detailed information that can be used to maximize system performance.
