feature descriptions

The features of the system are described below. Features that have additional settings that can be selected only

when programming with the Bitwriter® are indicated by the following icon:

1-1 ACTIVE/PASSIVE ARMING: When active arming is selected, the system will only arm when the transmitter is

used. When set to passive, the system will arm automatically 30 seconds after the last door is closed. To alert the

consumer of passive arming, the siren will chirp 20 seconds after the door is closed. This provides the consumer

with an audible warning prior to the system actually arming. At the 30 second mark, the system will arm, but

the siren will not chirp.

1-2 CHIRPS ON/OFF: This feature controls the chirps that confirm the arming and disarming of the system.

1-3 IGNITION LOCK ON/OFF: When turned on, the doors will lock three seconds after the ignition is turned on

and unlock when the ignition is turned off.

1-4 IGNITION UNLOCK ON/OFF: When ON this feature will unlock the doors when the ignition is turned off.

1-5 ACTIVE/PASSIVE LOCKING: If passive arming is selected in Feature 1-1, then the system can be programmed

to either lock the doors when passive arming occurs, or only lock the doors when the system is armed via the

transmitter. Active locking means the system will not lock the doors when it passively arms. Passive locking

means that the system will lock the doors when it passively arms.

NOTE: Remember, when passive arming is selected, the unit will chirp 20 seconds after the last

door is closed. The system does not actually arm or lock the doors until 30 seconds after the door

has been closed.

1-6 PANIC WITH IGNITION ON: This feature controls whether or not the panic mode is available with the igni-

tion ON. In some states, there are laws prohibiting a siren sounding in a moving vehicle. This feature makes the

system compliant with these regulations.

1-7 DOOR LOCK PULSE DURATION: Some European vehicles, such as Mercedes-Benz and Audi, require longer

lock and unlock pulses to operate the vacuum pump. Programming the system to provide 3.5 second pulses,

will accommodate the door lock interface in these vehicles. The default setting is 0.8 second door lock pulses.

Some modification to the door lock harness (H2) is also necessary. (Refer to TechTip 1041 for wiring informa-

tion regarding (+/-) Door Lock Outputs Harness (H4)section, Type E - Mercedes-Benz and Audi -1985 and Newer"

diagram.) The 0.4 second pulse is required on some of the newer Chrysler and Ford vehicles.

1-8 FORCED PASSIVE ARMING ON/OFF: To use this feature, passive arming must be selected in Feature 1-1. When
