The microprocessor at the heart of your security system is constantly
monitoring all of the switches and sensors that are connected to it. It
detects any faulty switches and sensors and prevents them from
disabling the entire system. The microprocessor will also record and
report any triggers that occurred during your absence. Refer to the
System Status Chirps and Table of Zones charts for diagnostic informa-
tion.
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 indicate 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 secu-
rity system resumes normal monitoring.
disarming diagnostics
Extra disarm chirps are the Tamper Alert. If four chirps are heard when
disarming, the system was triggered in your absence. If five chirps are
heard, a zone was triggered so many times that Nuisance Prevention
