Diagnostics (security only)
The microprocessor at the heart of your system is constantly mon i tor ing 
all of the switches and sensors connected to it. It is designed to detect 
any faulty switches and sensors and prevents them from disabling the 
entire system. The microprocessor will also record and report any trig-
gers that occurred during your absence. Refer to the Table of Zones 
sections of this guide for diagnostic information.
Arming diagnostics
When armed by remote command the system runs a status check of the 
alarm trigger zones. Faulty zones (usually caused by dome light delay 
or open trunk) are bypassed and reported via the control center LED, 
while all other trigger zones remain active and are monitored to protect 
the vehicle. Should a faulty zone self correct (dome light turns off) it 
becomes active and is then monitored normally. The siren chirps once 
again a few seconds following the arming chirps as an audible alert, 
the control center LED flashes in groups to indicate the zone number 
(see Table of zones).
Disarming diagnostics
The most recent alarm triggers (if any) are reported when the alarm 
is disarmed via the siren chirps, parking light and control center LED 
flashes. The siren chirps 4 times (or 5 times if NPC On), the lights flash 
3 times, and the control center LED flashes in groups to indicate the last 
two zones that were triggered (see Table of Zones).
Nuisance Prevention® Circuitry
Your system has Directed’s Nuisance Prevention Circuitry (NPC). It 
prevents annoying repetitive trigger sequences due to faulty door pin
