arming diagnostics
If the security system is armed at the same time that an input is
active (such as a door opening or sensor triggering), you will hear
one siren chirp to indicate arming and a second siren chirp to indi-
cate Bypass Notification. A Bypass Notification chirp means that
the security system ignores the input that was active when the
system was armed, until that input ceases. Three seconds after that
input ceases, the security system will resume normal monitoring.
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.
disarming diagnostics
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 trig-
gered 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 secu-
rity 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.
➜
note:
Bypass Notification does not occur when the sys-
tem is in Silent Mode or if the notification chirps have
been programmed off by the installer.
