’s Nuisance Prevention

Circuitry (NPC
). It
prevents annoying repetitive trigger sequences due to faulty door
pin switches or environmental conditions such as thunder, jack-
hammers, airport noise, etc. Here’s how it works:
The alarm triggers three times. Each time, the same sensor or
switch is triggering the alarm. The three triggers are within 60
minutes of each other. NPC
will interpret 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.
