For example:

If zone 3 was active or triggered, the LED will blink three

times with a two-second pause. Then it will blink three times again, and
repeat until the ignition is turned on.

Nuisance prevention® circuitry

Your system has Directed’s Nuisance Prevention® Circuitry (NPC). It
prevents annoying repetitive trigger sequences due to faulty door pin
switches or environmental conditions such as thunder, jackhammers,
airport noise, etc.

For example:

If the alarm triggers three times within a 60-minute period

and each time the same sensor or switch triggers the alarm, NPC will
interpret those triggers as false alarms. After the third trigger, NPC ig-
nores, or bypasses, that sensor or switch (along with any other sensors
or switches sharing the same zone) for 60 minutes.

If the bypassed sensor tries to trigger the security system while it is being
bypassed, the 60-minute bypass period will start over. This ensures that
a sensor that is continually being triggered will remain bypassed.

The vehicle doors are protected by NPC differently. If your security
system is triggered by an open door for three full cycles, the system will
bypass the doors until the trigger ceases.

Remote Start

This system can provide you with information to indicate what the problem is

when using the remote start. When the remote start is activated and fails to

engage, count the parking light flashes to determine the problem. The parking

lights will flash between 5 - 8 times to indicate what caused the no start situa-

tion.
