Nuisance Prevention Circuitry - Viper Responder 350 Owner's Manual

➜
Nuisance Prevention
Your system has Directed's Nuisance Prevention
(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
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 are covered by NPC
by an open door for three full cycles, the doors will be bypassed
until the trigger ceases.
note: Arming and disarming the system does not reset this
function. In order to reset a bypassed zone, the same zone
must not trigger for 60 minutes, or ignition is turned on.
