1-8 AUTOMATIC ENGINE DISABLE (AED) ON/OFF:
AED is a full-time, passive starter disable that works
independently of the security system. When turned on, the orange, ground-when-armed output (H1/1) will go
active 30 seconds after the ignition is turned off. The LED will flash at half its normal rate when the ignition is
turned off to indicate that AED is active and will interrupt the starter in 30 seconds. AED does not occur in Valet
®
mode and can be bypassed using the emergency override procedure. The transmitter can be used to disarm AED;
however, the system must be armed and then disarmed with the transmitter, in order to disarm AED.
1-9 ARMED WHILE DRIVING/VEHICLE RECOVERY SYSTEM:
In the default setting (Armed While Driving), the
system can be armed with the ignition on. When armed, the ground-when-armed is not active and the sensors
are bypassed. The door triggers will remain active. If programmed to the Vehicle Recovery System (VRS
®
) setting,
VRS will be activated.
1-10 CODE-HOPPING
™
ON/OFF:
The system uses a mathematical formula to change its code each time the trans-
mitter and receiver communicate. This makes the group of bits or “word” from the transmitter very long. The
longer the word is, the easier it is to block its transmission to the unit. Disabling the Code-Hopping
™
feature lets
the receiver ignore the Code-Hopping
™
part of the transmitted word. As a result, the unit may have better range
with Code-Hopping™ off.
2-1 SIREN/HORN HONK:
The system can be programmed to output pulses instead of a continuous output when
the system is triggered. This is useful to honk the factory horn in applications where a siren is undesirable.
Remember that the unit is only capable of supplying 1 amp of current. A relay will be required to interface with
most factory horn systems.
2-2 SIREN DURATION 30/60 SECONDS:
It is possible to program the unit to sound for 30 or 60 seconds
during the triggered sequence. Some states have laws regulating how long a security system can sound.
When using the TechSoft Programmer or Bitwriter™, the siren can be programmed to sound for any length of time
ranging from 1 to 180 seconds. Use the right and left arrows or the + and - keys on your keyboard to change the
siren duration in 1 second intervals. Holding down the key will rapidly increase or decrease the setting. The
desired siren duration can also be directly entered by using the number keys on your computer's keyboard. When
using the Bitwriter, pressing the SELECT button will adjust the siren duration.
2-3 NUISANCE PREVENTION
®
CIRCUITRY (NPC™) ON/OFF:
NPC™ stops repeated triggering of the same zone. If
one zone is triggered three times in one hour, that zone is bypassed for one hour, starting from the time of the
third trigger. During that hour, if the system detects a trigger on that zone again, the system resets the one hour
timer. If one hour passes and the zone has not triggered again, the zone is activated and can trigger the system
again. NPC™ only monitors sensor inputs, and does not bypass the door trigger or the ignition trigger at any time.
If NPC™ is turned off, the system will respond to repeated triggers on the sensor inputs and will do so indefi-
nitely. Some states have laws regulating how many times a security system can trigger before it is considered a
nuisance and the vehicle is towed away.
