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 Directed’s 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 are covered by NPC

differently; if the alarm is triggered

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.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 dis-

arming, NPC

has been engaged. If you wish to clear the

NPC

memory, turn the ignition key on.
