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). Connect the shortest connection of the LED to the earth (chassis) 
and its shortest connection to the point LD1 of the circuit.  
 

(A)  Car burglar alarm used as stand-alone unit. 

 



Connect the klaxon or siren to the relay as shown in the figures.  



Attention: 

The common wire of the klaxon can be connected either to the + or the - of the alarm (check with a volt-meter). 



Connect the connecting terminals"+" and"-" of the alarm to the corresponding poles of the battery. 



For normal use, connect the point DIS of the circuit to a"+" wire AFTER the ignition lock.
