inputs. The hood input will prevent the motor from starting, as
well as shut it down, any time the hood is opened. The brake
pedal will shut down the motor at any time during remote start
operation, as well as preventing the remote start from activating
while it is being pressed.
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.
