WOW Override
The WOW switch may be overridden by rotating the control knob on the Control Panel from TEST
to ON to TEST to ON in less than 2 seconds. Upon completion of that action the system shall go into
normal radiate ON condition and permit selection of normal operating modes. If the Control panel
switch is returned to TEST or Standby modes, then system operation shall return to normal. If the
WOW switch has been overridden and the WOW switch is in the airborne condition, the system
modes shall operate normally and any override conditions deleted.
