Diagnostics
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 information.
ARMING DIAGNOSTICS
If the system is armed while an input is active (door open, sensor triggering, etc.) the unit will
chirp once when arming and then one more time a few seconds later. This is called Bypass
Notification.
NOTE: Bypass NOTIFICATION will not occur when using
Silent Mode™ or if chirps have been programmed OFF.
The security system will ignore the input that was active when the system was armed, until the
input goes away. Three seconds later the system will monitor that input normally. For example, if
your vehicle has interior light exit delay, and you arm the system before the interior light goes
out, you may hear Bypass Notification chirps. Once the light shuts off, however, the doors are
monitored normally.
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
®
Circuitry has bypassed that zone. The in-vehicle status LED will indicate
which zone was involved. (See Table of Zones section of this guide.) The system will retain this
information in its memory, and continue to chirp four or five times each time it is disarmed, until
the next time the ignition key is turned on.
SYSTEM STATUS CHIRPS
The siren will chirp when arming/disarming the system. The pattern of chirps will audibly report
the system’s status as described below.
Action Number of Chirps Description
Arm 1 System armed
Arm 1 + 3 sec delay + 1 System armed with Bypass Notification
Disarm 2 System disarmed
Disarm 4 System disarmed with Tamper Alert
