Bypassing Sensor Inputs
There are times when you need to temporarily bypass all sensor inputs to the unit, such as when
remote starting the vehicle. Anytime an auxiliary channel output is used, all inputs are bypassed for
5 seconds. During the 5 second bypass period, ground can be supplied to the H1/6 Blue wire
without triggering the unit. When the 5 second bypass period ends, if the unit sees ground on the
H1/6 Blue wire, all trigger inputs except the door trigger input will remain bypassed until 5 seconds
after ground is removed from the BLUE wire. This can be done using the status output of a Directed
Electronics remote engine starting unit as shown in the following diagram:
System Features Learn Routine
The System Features Learn Routine dictates how the unit operates. Due to the number of steps,
they have been broken up into two menus. It is possible to access and change any of the feature
settings using the Valet/Program switch. However, this process can be greatly simplified by using the
998T Bitwriter. Any of the settings can be changed and then assigned to a particular transmitter, up
to four, a feature called Owner Recognition. Each time that particular transmitter is used to disarm
the system, the assigned feature settings will be recalled. Owner Recognition is only possible when
programming the unit via the 998T Bitwriter.
If the system was previously programmed using the 998T Bitwriter, the learn routine may be
locked. If the siren generates one long chirp when attempting to program the unit, the learn routine
is locked and must be unlocked using the 998T Bitwriter.
