Table of Zones
The zone number is the number of LED flashes used by the system to iden-
tify that input. The standard input assignments are listed below, along with
spaces to write in any optional sensors or switches you have had installed.
If the Warn Away ® response is triggered, the LED will not report it.
Code Hopping ™ E
XPLAINED
The receiver and transmitters each use a mathematical formula called an
algorithm to change their code each time the transmitter is used. This technol-
ogy has been developed to increase the security of the unit. The control unit
knows what the next codes should be. This helps to keep the transmitter “in
synch” with the control unit even if you use the remote control out of range of
the vehicle. However, if the transmitter has been pressed many times out of
range of the vehicle, or the battery has been removed, it may get out of synch
with the control unit and fail to operate the system. To re-synch the remote
control simply press the arm/disarm button of the remote control several times
within range of the vehicle. The alarm will automatically re-synch and respond
to the transmitters normally.
