snippet: Programming Cable for VFS/FS. The Alpha Communications® / S.T.R.™ EMPK-VFS/FS and EMPK-VH/HT QwikBUS™ Programming Cable is designed to be used in conjunction with various QwikBUS™ intercom/emergency stations, to make station programming much faster and easier than competitor's systems, and to allow a single person to program the stations. The EMPK-VFS/FS is used with the FS1000, FS1500, FSE1500 and VFS1000 series (open voice style) intercom and video-intercom stations. The EMPK-VH/HT is used with the HT3033, VH3033 and VHC3033 series (handset style) intercom and video-intercom stations. Typically one end of the EMPK cable is connected to the QwikBUS™ system power components and the other end plugs into the associated QwikBUS™ station. (Page 1)
