The Wireless Expansion Trigger (STPF-WSX) is a versatile installation tool. Use the eight outputs to trigger things like gates, lighting, and automation systems by connecting the WSX outputs directly to what you want to control. Toggle the outputs or program momentaries up to 255 seconds. Or use the WSX to add up to 24 wireless sensors to any standard third-party hardwire control panel. (To add wireless sensors to the Sequel ST8 control panel use the STPF-EXT.) Using unique duplex frequency diversity, the WSX receives radio signals on two separate frequencies, providing enhanced reliability when compared to competitive systems. In addition, the WSX includes a protocol decoder, which allows it to receive signals from select GE and Honeywell wireless sensors, as well as the entire line of Sequel wireless sensors and devices.
