The FA113 has not been properly programmed into the D8125INV. Points 74 (194 on zonex 2) and 75 (195 on zonex 2) must both be learned into the D8125INV.
The FA113 Keyfob has four buttons: ON, OFF, and two Alert (*) buttons. The ON button is used to arm the area point 74 or 194 (zonex 2) is assigned to and initiate the Master Arm Delay state. The OFF button is used to disarm the area to which the point is assigned.
The Point Index for Point 74 and 194 must be programmed as a Point Type 4, Point Response 2.
When both Alert buttons (stars) are pressed, the D8125INV sends a Short to the control panel for Point 75 or 195 (Zonex 2). Program the control panel accordingly so that the Point Response provides the appropriate response on short.
Pt74 or 194 (zonex 2) must be learned as a new point. Point 75 or 195 (zonex 2) is leaned in as an existing point. When programmed incorrectly and both star keys are pressed, Servc RF Low Battery is generated on the panel command center. The FA113 is learned into the D8125INV using mode 4.
