its normal rate when the ignition is turned off to indicate that Automatic Engine Disable is active and
will interrupt the starter in 30 seconds. Automatic Engine Disable does not occur in valet mode and can
be bypassed using the emergency override procedure. The remote can also be used to disarm
Automatic Engine Disable.
1-9 ARMED WHILE DRIVING/ANTI-CARJACKING 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 Anti-
Carjacking System setting, it will be activated.
1-10 ANTI-CODE GRABBING ON/OFF: The system uses a mathematical formula to change its code
each time the remote and receiver communicate. This makes the group of bits or "word" from the
remote very long. The longer the word is, the easier it is to block its transmission to the unit. Disabling
this feature lets the receiver ignore this part of the transmitted word. As a result, the unit may have bet-
ter range with Anti-Code Grabbing off.

2-1 SIREN/HORN HONK: The system can be programmed to output pulses instead of a continuous out-
put 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 secu-
rity system can sound. When using the Pro Security Programmer, the siren can be programmed
to sound for any length of time ranging from 1 to 180 seconds. Using the SELECT button of the Pro
Security Programmer will adjust the siren duration in one second increments.
2-3 FALSE ALARM PREVENTION CIRCUITRY ON/OFF: 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. This circuitry monitors sensor inputs and the door trigger, but does not
bypass the ignition trigger at any time. If false alarm prevention circuitry is turned off, the system will
respond to repeated triggers on the sensor inputs and will do so indefinitely. Some states have laws reg-
ulating 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 pro-
gressive 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 pro-
grammed off, the full siren output will occur the moment the door is opened.
