98´Volvo s70 alarm no sound

[Radaren]

i have an Volvo s70 1998 with volvo guard. When i lock the car the little red LED flash normally. And when i trigger the alarm, the warning lights around the car start to blink, and inside the car i can hear a ticking, but i cant hear any sound from the horn. under the hood i can see a little round horn, i have tested it on the battery and i know that it works. in the cable into the horn i have tested the ground connection and i know that one is working. but how do i test the other + connection, where is that wire going? can it be an another reason why the alarm doesn't make any sound? :L

Hello,
The alarm siren is hidden inside the cavity at the front of the O/S wing.
See my other post which provides a link to a further post where a forum member swapped it.

but when i have the alarm horn, does it also have the siren? and where is it placed? does all s70´s have the siren, and if, why does i have the little horn over the engine?

Hello,
Where is the little horn located you are referring to?
To the best of my knowledge all C/S/V/XC have the alarm siren. It is harder to access to deter thieves from being able to deactivate the siren.

the horn is located like on this picture, if you looks under the windshieldwiper. just open this picture and look;

is this maybe a back up horn? i know my alarm is original volvo guard. but does anyone have a video of the alarm sound and how it work so i can see?

Hello,
I haven't seen that before.
You will have a siren inside your inner wing, and it is this that isn't sounding, if the siren were so accessible any would be thief could pop the bonnet and silence it in seconds.

What leads you to believe this is part of the alarm system?
It is indeed the siren, I have just noticed you are in Norway! Perphaps a different set up for continental car alarm systems?

That is exactly how my S70 is. Horn sounds for the alarm, there is no siren.

Hello,

Sounds, pardon the pun, like the siren has an adjusting knob which could be a volume control? on the tip. Try adjusting this.

do you have any idea why my horn doesnt sound when i trigger the alarm, even my lights are blinking around the car? i know the horn is working, i have tested it on 12v maybe the last owner of the car have disconnected the alarm sound. does anyone know how te reactivate it if thats the case? or what can i do so it start working again? and thanks for good and quick answers from you

i have also tried to trigger the alarm and tested the plug who goes into the horn, with a multimeter, i didnt get pusling 12v there when the horn where supposed to sound

i have also tried loosing and tightening the bolt on the horn, but it still doesnt work....

Hello,
Pop your O/S indicator, on mine you can see the siren in it's housing in the void behind.
