pedal will shut down the motor at any time during remote start

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.

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

ignores, 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.
