Diagnostics

The microprocessor at the heart of your system is constantly monitoring all
of the switches and sensors connected to it. It is designed to detect any
faulty switches and sensors and prevent them from disabling the entire
system. The microprocessor will also record and report any triggers that
occurred during your absence.

Refer to System Status Chirps and Table of Zones sections of this guide for
diagnostic information.

➤ Arming

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 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 off by the
installer.
