The status LED will light solidly if you have entered Valet Mode and
will turn off if you have exited Valet Mode.
Your security system has Nuisance Prevention Circuitry
(NPC
) to
prevent annoying false alarms. This circuitry is designed to prevent
repetitive trigger sequences due to faulty door pinswitches or envi-
ronmental conditions such as thunder, jackhammers, airport
noise, etc.
Here's how it works: If the alarm is triggered by the same sensor
or switch three times within a 60 minute period, your system
interprets this pattern of 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 is triggered again while it is
already being bypassed, the 60-minute bypass period will start over,
ensuring that a sensor that is continually being triggered will
remain bypassed.
The vehicle doors are protected differently by NPC
. If your secu-
rity system is triggered by an open door for three, full 30-second
cycles (one and one half minutes), the system will bypass the
doors until the trigger ceases.
