When the alarm is triggered, I can here the relays but the lights aren't flashing and no sound is emitted.
Is there a fuse or a relay I'm missing?
This may help.
When I lock the doors with the remote the lights aren't flashing neither.

Can't help with the alarm not sounding but when you do a "normal" lock via the remote, the lights don't flash.. If you double lock it - i.e. hit the lock button on the remote twice then the indicators will do a quick double flash.

Well, that's the problem, when I double lock, the indicators won't flash.

Not all models flashed or make a sound - did they when you bought the car?

Do the indicators work when the hazard button is on?

Some one may have disconected the horn to stop it sounding if it went faulty. the horn is situated behind the battery.
Not all versions of the scorpio had the flash on lock . it is only the very latter ones that had it, or those that had a software upgrade.
The main cause of the alarm sonding when parked is a faulty bonnet sensor! clean the contacts on that and all sould be well if that was/is the cause.

Eric, as a matter of trying to drill down into your problem - what exactly do you do to "trigger" the alarm? Open a door from the inside? break a window? 
This assumes the alarm being set first. How do you set it? Remote double-lock? Key double-lock?
Do you have the standard alarm or the movement-sensor type?
Curious,
Ray

I have a standard alarm, so, no movement sensors. I checked the horn and it's connected.
My '98 Scorpio confirmed double-locked by flashing with the indicators. One day it stopped doing it. Then suddenly it worked once. But since this day it never worked again.
To set off the alarm I double-lock the car (remote double-lock) and push the bonnet sensor.
Yet an other problem has occurred. I can't register neither my actual remote nor the old one from my '95.
Fortunately the one which came with the is working at time.

Eric, a combination of EEC-V, CCM and some other obscure parts are responsible for correct behaviour.
You might just try unclamping the neg pole of your battery; give it a coffebreak's rest and reinstall again.
You will see the typical flicking needles of your dash after reset and contact; that's normal after reset of EEC-V and CCM. It may work for your problem; if not, then there's a few other attempts.
When you hold the mileage resetbutton for 10 secs you enter testmode and by pressing again you may e.g. check batt voltage and other stuff; see here:
http://www.fordscorpio.co.uk/instreset.htm
Batt voltage when engine off should not be below 11 Volts; when running around 14 V is appropriate.

Does the BAR on the 1-2-3 switch unit produce a DING-sound at all when pressed?
Does the DING DING sound work when you open a door with the gearlever not in P?

I see Thx for your help so far.
I will do some testing this weekend and report afterwards.
I don't have an automatic gearbox, but there is a "ding ding" sound when I leave the lights on and open the door.
What or where is the "BAR on the 1-2-3 switch unit"?

I am sorry - that is a programming panel for adjustbale seats and mirrors below on the drivre's door - not on all models.
DING DONG signifies your Central Timer is working. This is the unit responsable for all timing jobs in the car, interior lights, heated window and a few others.
What model/year/options is your Scoprpio?

Eric -
Since this problem has my full attention as an electronics engineer "Scorpio-specialised", trying to drill down into your problem - what exactly do you do to "trigger" the alarm? Open a door from the inside? break a window?

Have you had the battery disconnected/changed?

@Corsay: To set off the Alarm, I leave the driver window open, double-lock the car, open the bonnet and push the bonnet sensor if the alarm doesn't go off immediately. I can hear two relays click. I assume one for the indicators and the other for the alarm horn.
@Highlander: Yes, I had the battery disconnected several times.

Eric, please bear with me. There is an inconsistency in what you say - for me to understand and judge properly.
To "set" an alarm means arming it. To 'trigger" means to make it sound.
Now you say you "To set the Alarm, I leave the driver window open, double-lock the car, open the bonnet and push the bonnet sensor if the alarm doesn't go off immediately. I can hear two relays click. I assume one for the indicators and the other for the alarm horn."
Why on earth would you press the bonnet sensor (a simple on-off switch; not a sensor) to make the alarm sound "if it does not sound immediately? "
What is the purpose of that excercise?
If you press the bonnet sensor (quickly enough) it would prevent the alarm to sound. For what reason would you do that?
One relay would click - though you must have deadsilence - which is the 4-corner-alarm relay. I cannot think of a second relay to click.
Please do try to do the EEC-V and CCM reset-excercise by disconnecting the battery on the neg side for 5 mins.
It might just cure these strange conflicting observations.
HTH
