2. Turn the ignition On for more than 1-second and less than 3-seconds.
3. The siren will chirp once to indicate one-time bypass has been activated.
To cancel one-time bypass perform one of the following:
Arm then disarm the alarm.
Turn the ignition On for more than 3-seconds.
NUISANCE PREVENTION
®
CIRCUITRY
Your system has 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 system while it is being bypassed, the 60-minute bypass
period will start over. This ensures that a sensor that continually triggers will remain bypassed.
Doors and the ignition switch are covered by NPC
®
differently; if the alarm is triggered by an open
door or ignition ON for three full cycles, the zone will be bypassed until the trigger ceases.
NOTE: Arming and disarming the system does not reset this function.
The only ways to reset a bypassed zone are for it to not trigger for 60
minutes, or to turn on the ignition. If testing your
system, it is important to remember that the NPC
®
programming
can cause zones to be bypassed and appear to stop working. If five
chirps are heard when disarming, NPC
®
has been engaged. If you
wish to clear the NPC
®
memory, turn the ignition key on.
NPC
®
is On/Off programmable. See your dealer and the Programming section of this guide for
more information.
