setting is 0.8 second door lock pulses. For some vehicles a 0.4 second pulse duration is required to
prevent the windows from moving.
1-7 FORCED PASSIVE ARMING ON/OFF:
To use this feature, passive arming must be selected
in step 1-1. When turned on, forced passive arming will ensure that the system will passively arm,
even if a zone is left open or invalid. Forced passive arming occurs one hour after the ignition is
turned off.
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 also be used 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 transmitter 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 applica-
tions 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 998T Bitwriter, the siren can be programmed to sound for
any length of time ranging from 1 to 180 seconds. Using the SELECT button of the 998T Bitwriter
will adjust the siren duration in one second increments.
