Hi...First count the number of sensors and
detectors that you have physically
installed. Next, preview the zones
(including 9-16 using the bypass button) to
see if you have any slow flashing zone
lights. If so, press the TEST button on the
detector or sensor that represents the slow
flashing zone and see if teh slow flashing
disappears. If not, you are going to have to
re-register all the sensors and detectors
again so remove the console battery and AC
power. Reapply power and re-registor all
units including controls. If the slow
flashing zone light disappears, then halting
all activity in/out of the house, move the
switch to INSTALL and verify how many zones
are registered (LED for each registered zone
will be lit. Be sure to press BYPASS to
view zones 9-16). If you have more zones
than you have motions and sensors installed
then you need to remove all power and
reregister. Otherwise...the five dings
should go away. We hope. Good luck.
