Viper 790xv, 2000 Accord Ex

I need some help.  I have a 2000 honda accord and just installed a viper 790xv.  I also hooked it up to airhorns as well as the original siren included with the alarm.  My problem is the installer toned down the airhorns by making them "chirp" for a short period of time by putting a diode in between of the wire, I want the siren to be loud and chirp for a longer time but I'm not sure if the diode is there to do that or if there was another reason that the diode is there.  I thought he was suppose to use a resistor instead so I'm not sure what would happed if I take out the diode.  Any help would be appreciated.  Thanks

The arm and disarm chirps are just that, chirps. There is no way to make them louder for the chirps( the compressor barely powers up when the alarm chirps, that is why they are quiter) without getting into relays and timing. Besides why the hell would you want air horns going off when you arm and disarm the alarm, they are meant for when the alarm is set off? Have you tried to panic the alarm and see if it gets loud?

I've been sick lately, sorry I won't be on much.

Okay, I guess I didn't explain myself that clearly.  I am trying to say that when the alarm goes off the air horns honks (sounds off) but for short periods of time like, it honks for a second then pauses for 2 seconds then honks again for a second and so on.  The installer told me he was gonna do this to make it not too anoying.  But it's really not enough for me.  I see that there is a diode installed inbetween the wires.  I was wondering if this is what he did to make it sound off for a shorter time.  So if I take out the diode, will that solve my problem or is it there for another reason.  Hope this is much more clearer to understand.  thanks

Which wires did he put the diodes on/between?

Does the siren sound constantly or does it pulse during a panic also?

Might want to get the programming manual from www.directed.com and regrogram the output from pulsed to constant (or at least check to see which it is set at).

Sup Fellas, I got a question.  I have a 2000 Accord with the viper 790xv installed.  Everything works fine.  I would like to hook up my factory horn to my alarm so the horn goes off with the alarm.  How do I go about doin this??  I don't know much about alarms, so please go into details.  Thanks

I'm the alarm man......

Okay those horns on these cars are neg. so you want to do this...

85....ground it

30....ground it

86....brown wire on alarm.

87....to the horn.  You will also need another wire for the regular sirens...

Don't let the smoke out of your equiptment..it doesn't go back in.

rookie is wrong theres something dei  makes that comes with a relay and a flasher  prewired and explained in detail on how to wire it up idont remember exactly what part number it is but if u go to  where u got your viper at im sure thy will have it dei is the name company that makes this device and viper also.

with your alarm you should have a BROWN / black wire which is for (-) horn output.  If your horn is a (-) trigger, simply connect the BROWN / black wire to it.

Got a question. The car is a 2000 accord V6.  I have a viper 790XV with 2 viper 514n sirens and a set of airhorns.  It was programmed to pulsed and the airhorns just sounded off short and quick and not at full power and the viper sirens too. (sounded weird)  I changed it to constant and the airhorns just went off full blast and the sirens too.  How can i set the sirens to go at full blast and the airhorns to go off pulsed but longer stronger pulses?? Is that possible. Thanks

Not possible, you have to pick either pulsed or constant.

The viper 5000 has 2 output during full trigger (siren & horn that can be programmed to sound during full trigger).
This is an option for your exact desire.

I guess you could set it for no pulse and install a flasher on the airhorns....

WAIT! there is a way.

Set alarm to pulse and use a relay.
Pulsed to Steady

Then have your steady output to the siren

Another relay to power your airhorn

(i havent done the pulsed to steady, because i didnt want to buy a capacitor and deal with that stuff. theoretically it should work, i havent personally done it to say that it will work 100%)

Thanks guys.  I will try your way captainzab.  Looks like it might work, I really didn't want to deal with capacitors and resistors either, but this looks like the only way. Thanks

Hi, got a question.  I read up on relays and the special applications.  Now I need a steady to pulsed output instead of the other way.  Is this possible? thanks

Dei makes a door lock pulse generator that will do it pn#452t

~wirewise~

okay, i got the air horns to pulse using a flasher,(connected between the relay and the horns) works great but air horns sound lower than before, but I guess I just gotta deal with that, unless someone has a solution for that.  Okay, heres another problem, I want to hook my Factory horn to my alarm too, but want it to pulse.  I know that it's a negative trigger wire. (Constant 12V until pressed) I tried hooking a flasher to it but won't work.  Just constant.  How would I go about wiring this up?  I think the flasher didn't work cause its a 12v flasher.  Please help, I know I can look for the positive trigger wire for the horn somewhere in the hood but would rather hook it up to the negative trigger wire which is underneath the dash where all of the thousands of wires are. Thanks.

Is it possible to arm the factory alarm with my viper 790xv?  Instead of arming the car with the viper remote first then using the factory remote to arm the factory alarm, Can I use the viper to arm both? I wanna use both but it would be nice to have just one remote on my keychain if it's possible. The car is a 2000 accord EX V6.  Thanks

on the ex models the factory alarm arms automatically when you lock the car. Just use the viper to lock doors and the factory alarm will arm.

I wish that was true but it isnt.  When I lock the doors it doesn't arm the factory alarm.

this is what directwire has:

HONDA, ACCORD, 2000, Factory Alarm Arm

Arms and disarms with the door locks on the EX models. The LX models arm only with the factory transmitter.

okay I know that the factory disarm is in the door panel, I guess the arm wire is there too.  But how do I connect that wire to the alarm?
