When the control panel is sending AC Fail reports but not AC Restorals, set program item # 27 [AC Res] to YES. This programs the panel to send AC power restoral reports "zone 0" to the central station receiver.
BFSK or Modem format is required.
If no AC trouble is transmitted, no restoral will be transmitted.
AC trouble is reported only when AC is off at the time that another report is being transmitted.
