nuisance prevention circuitry

Your system has Nuisance Prevention Circuitry

(NPC

) to prevent

annoying repetitive trigger sequences caused by faulty door pin switch-

es or environmental conditions such as thunder, jackhammers, airport

noise, etc.

Here’s how NPC

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, your sys-

tem 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. This ensures that a sensor

that is continually being triggered will remain bypassed.

note: Arming and disarming the system does not reset the

Nuisance Prevention Circuitry

. The only ways to reset a

bypassed zone are for that zone not to be triggered for 60

minutes or to turn the ignition key on. When testing your sys-

tem, it is important to remember that this circuitry can cause

zones to be bypassed and appear to not work. If five chirps

are heard when disarming the system, the NPC

was

engaged. To clear the memory, turn the ignition key on.
