Installation guide

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 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 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 incre-

ments.
