dei 515r

Hello, I have installed Dei 515R siren with older bosch vim vss001 and sub models vim 2002 and iron kit 3003 . Before the new siren installed the alarm worked fine with the backup siren which is in the car . Also the small speaker which sounds the beeps when the card is opened or closed is disconnected because the burglar riped the wires, but the beeps can still be heard from the "in car" siren .     The alarm was installed in the car from day one and i installed the siren because it the old one stoped working. The siren is connected through 3 wires . (out of four) the alarm works as it should with one tone . but when i try to start the car and turn the switch, the multiple alarm tone sequence starts . ( its suppose to be 6 tone but i didnt count if its only 5 out of the 6 ) . What am i missing here ?

Forth line is "car" , not "card".
