Overview
PowerG S-Line contact — encrypted 2-way door/window sensor for IQ Panel and IQ Hub systems (IQ Door/Window-S, DW Mini-S, DW Extended-S, Recessed-S).
On IQ Panel systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.
