- Page 2 Features & Specifications The alarm detects sudden voltage drops of the battery when the interior, trunk, or hood lights are switched on. To ensure correct operation, a number of control indications have been included, such as : flashing LED to indicate that the alarm is in standby mode after a set time (after you have left the car).
- Page 3 Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: A good quality soldering iron (25-40W) with a small tip.
- Page 4 Assembly hints 1.3 Soldering Hints : 1- Mount the component against the PCB surface and carefully solder the leads 2- Make sure the solder joints are cone-shaped and shiny 3- Trim excess leads as close as possible to the solder joint REMOVE THEM FROM THE TAPE ONE AT A TIME ! DO NOT BLINDLY FOLLOW THE ORDER OF THE COMPONENTS ONTO THE TAPE.

- Page 8 Test & usage 13. Test & Usage Connect the LED between the points LD1 and the earth (-). Connect the + and - of the battery direct to the + and - connections of the circuit. Remark: switching the + and - connections by mistake will only cause IC1 to be destroyed, because the rest of the circuit is protected by D7.
- Page 9 Test & usage Connecting the point DIS to the + should extinguish the LED. Interrupting the connection should restore the flashing state after 2 seconds. This delay time, which is the step out delay time or in other words the delay time between the point of time the voltage disappears from the point DIS (coming from the ignition lock or from the remote control) and the rearming of the alarm, can be made longer with RV1.

Page 10: Final Connection
Final connection 14. Final Connection Take care that the under mentioned connections cannot be cut through from the outside. You can install a lamp under the bonnet which activates the alarm when the bonnet is opened. Install the LED by preference at a place where it is visible from the outside (use the supplied LED-holder if necessary). - Page 11 Final connection 2.
