SWIFT wireless detectors communicate across a Class A mesh network. Wireless detectors create an opportunity for applications where it is costly (concrete walls / ceilings, buried wires), obtrusive (surface-mount conduit), or possibly dangerous (asbestos) to use traditional wired devices. In addition, both wired and wireless devices can be present on the same Fire Alarm Control Panel (FACP), providing an integrated wired-wireless solution for increased installation potential.
