Adjustment - Velleman SP500B Mode D'emploi

B. Wiring of the 2-pin connector
1. Blue wire – ground trigger input
This wire is the ground input trigger wire for additional bonnet / boot or door pin switches and for
additional ground output sensors such as an ultrasonic detector, etc.
2. Violet wire – current sensing circuit
The violet wire controls the current sensing circuit
a) This alarm system is equipped with a built-in electronic parallel circuit for the fan. The
electrical fan of some vehicles may trigger the alarm system when the latter is armed.
The violet wire must be connected with the fan's +12V if this happens.
b) Tape the end of this wire if your vehicle doesn't have a cooling fan.
c) Connect the violet wire directly with the + side of the vehicle's battery if you do not want
voltage drop detection.
3. Thin black wire – RF antenna
The thin black wire is the receiver antenna wire. The placement of this antenna is extremely
important! Ensure that it is unwrapped and stretched up until the last 6". Keep it away from
metal objects or the chassis for optimal reception.
4. Programming and Adjustment
Now that the wiring is completed we can program the transmitter code, the shock sensitivity and
the alarm tone.
A. Programming transmitter code
The transmitter code should be programmed when the alarm is completely installed. Only 2
transmitters can be used with a single unit. Proceed as follows:
Disconnect the power and reconnect the system after 10 seconds. Press transmitter button I
(=largest button), the siren will beep once.
If you have a second transmitter: press button I on this second transmitter within 5 seconds of
programming the first transmitter. Again, the siren will beep once to indicate that the transmitter
has been programmed.
Attention: the transmitter code is not memorised if power to the alarm is lost. The code will have
to be reprogrammed according to the same procedure (see above).
B. Shock sensor sensitivity adjustment & testing

ADJUSTMENT

Disarm the system and hold both buttons on the transmitter for 2 seconds. A beep will confirm
that you have entered the programming mode.
