Silent Knight WSK-WGI Swift Wireless Fire System Gateway

Description

The SWIFT® (Smart Wireless Integrated Fire Technology) Wireless System can be applied in many situations that are problematic for traditional wired devices. In cases where areas of a building are difficult or impossible to wire, visually sensitive, or have restricted access, SWIFT wireless sensors provide an efficient, reliable solution.

SWIFT wireless devices communicate via a proprietary wireless mesh protocol to communicate with a Silent Knight® fire alarm system by means of a SWIFT wireless gateway. The SWIFT gateway connects to the SLC loop of a 6700, 6808, 6820/EVS panel using SK protocol. New type IDs for wireless devices are supported that allow the FACP to display all events such as alarms and trouble indications, as well as unique trouble conditions required for wireless devices. This capability eliminates the need for a supplementary annunciator for wireless event messages.

Wireless devices in a SWIFT network develop “parent-child” communication links with other devices in the mesh, so that a message originating from a remote device “hops” to the closest parent device, and then to successive parent devices until the message reaches gateway. Alternate paths are also identified and supervised by the SWIFT protocol providing approved Class A wireless communication. If a device does not have an established communication path with adequate signal strength, an additional device such as a wireless module may be installed in between so that it will act as a repeater.

A SWIFT gateway system supports up to 50 devices: 1 SWIFT gateway and up to 49 wireless detectors, modules, pullstations, and A/V bases. The maximum number of gateways on a system is limited by the number of available SLC addresses on the FACP, or a maximum of 4 gateways within common wireless range.
