Use the wireless PAL type for instances where high voltage control of airport lighting is a far distance from the SayWeather installation location or instances where routing or burying a control wire to the high-voltage lighting control point is cost prohibitive. The PAL-1W and PAL-3W consists of a wireless lighting interface (WLI) and power relay panel (PRP). The WLI acts as a control signal transmitter and it includes a manual lighting control switch on the front panel. (The WLI connects to SayWeather through an industry-standard 6C6P cable.)
