Hey!

I'm trying to connect my car horn to the cyclops alarm system. I want the horn to go off with the alarm siren.

Can anyone point me in the right direction? I've tried to search with no luck.

The car is a 95 civic.

Thank!

How do you mean?

If I run the horn off the siren output, it just honks once for a split sec then again when the alarm is switched off.

are you asking how to hook it up so you can press a button on your alarm and it goes off untill you let go? if so just wire one of the alarms outputs to a relay which is connected to the horn. I have my air horn hooked up this way. works like a champ.

I want it setup so that when the siren goes off, the horn will honk aswell.

The siren output from the control box is just a quick short pulse (as if it's switching a relay on in the siren) on and then off once the alarm is switched off.

As nouseforaname was saying, when the alarm is in an alarm condition, the siren output is a steady output, rather than a pulsed one; you may or may not want the horn to simply lock on continuously if your alarm gets tripped.

That's different from what you're seeing when you just arm and disarm the alarm, where it's just a short chirp output.

The horn probably won't like the long period of continuous activation, though it'll sure be annoying enough-  if you want to do it, I'd try just leaning on the horn for as long as your alarm timeout period is, as a test.  If you like it and it survives, then you can just hook it up with the relay to switch the horn power
