Whenever the vehicle is remote started, advanced anti-grind cir-
cuitry will prevent the starter from engaging, even if the key is
turned to the start position. This prevents damage to the starter
motor if the key is turned to the start position during remote start
operation.
NOTE: The starter anti-grind circuitry only works when the remote start
system is operating the motor and the Failsafe
® Starter Kill relay has been
installed.

The microprocessor at the heart of your system is constantly mon-

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
