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.
Menu #2 - Advanced Features
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.
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 indefinitely.
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.
2-4 PROGRESSIVE DOOR TRIGGER ON/OFF:
The system responds to a door trigger input with a progressive
response. When the door is opened with the system armed, the siren will chirp 10 times prior to the full triggered
sequence. The door trigger is still treated as an instant trigger and closing the door quickly will not prevent a full
triggered sequence from occurring. If the progressive door trigger is programmed off, the full siren output will occur
the moment the door is opened.
2-5 VALET PULSE COUNT 1 TO 5 PULSES:
The system can be programmed to count the number presses of the
valet switch before disarming the security system or VRS
®
. The factory default setting is one pulse. The unit can be
set for 2 to 5 pulses using the two-chirp setting to select the pulse count.
GHOST SWITCH OPTION: For added security, the GRAY wire on the two-pin Valet
®
/Program can
be connected to any switch in the vehicle that provides a positive (+) momentary pulse.
2-6 DOOR TRIGGER ERROR CHIRP ON/OFF:
With the door trigger error chirp programmed off, the system will
not report an invalid zone on arming when the door trigger wire is active.This eliminates the extra chirps that occur
when interfacing with vehicles that have exceptionally long dome light delay circuits.
2-7 IGNITION-CONTROLLED DOMELIGHT SUPERVISION ON/OFF:
If turned on, the system will turn on the
domelight for 30 seconds when the ignition is turned off. The optional domelight supervision feature must be
installed.
2-8 DOUBLE PULSE UNLOCK ON/OFF:
Some vehicles require two pulses on a single wire to unlock the doors.
When the double pulse unlock feature is turned on, the BLUE H2/C wire will supply two negative pulses instead
of a single pulse. At the same time, the GREEN H2/A wire will supply two positive pulses instead of a single
pulse. This makes it possible to directly interface with double pulse vehicles without any extra parts.
2-9 CHANNEL 3 VALIDITY/LATCHED/LATCHED RESET WITH IGNITION/30 SECOND TIMED/SECOND
UNLOCK OUTPUT:
Channel 3 can be programmed for these output configurations. The unit is set to the default
validity output. To change the configuration, use the two-chirp setting to toggle to the different configurations.
