that input ceases, the security system will resume normal moni-
toring. For example, if your vehicle has an interior light exit delay
and you arm your security system before the interior light turns
off, you may hear a second Bypass Notification chirp. Once the
light turns off, however, the security system resumes normal
monitoring.
NOTE: Bypass Notification does not occur when the system is in Silent
Mode or if the notification chirps have been programmed by the installer
not to sound.
Extra chirps that are heard when disarming the system are the
Tamper Alert. If four chirps are heard when disarming the system,
then the security system was triggered in your absence. If five
chirps are heard when disarming the system, a zone was triggered
so many times that the Nuisance Protection Circuitry ™ has bypassed
that zone. In either case, the status LED will indicate which zone
was involved (see Table of Zones section). The security system will
retain this information in its memory and chirp four or five times
each time it is disarmed, until the next time that the ignition is
turned on.
A zone is represented by the number of LED flashes used by the
system to identify a particular type of input. Standard input
assignments are listed in the following table, along with spaces to
write in any optional sensors or switches that have been installed.
