i installed a 2 sets of airhorns and the units siren and the cars factory horn to the unit .it works but if the alarm gets set off it is really hard to turn it off with the remote. but when i disconnect the airhorns and factory horn i can just press the button 1 time and it goes off what could be the problem and i am using relays.
i have 1 relay running off the output of the alarm that is hooked to the airhorns sirens and factory horn can u tell me a way or show me a diagram how to install this the correct way. do i need a relay for every accessory and a relay off of the siren output.
does anyone know how to hook this up the correct way i want the facory siren factory horns and airhorns hooked up to my valet 554r
you have a feedback problem.
hook it up like this
2 relays
tap a wire off of your alrm wire and connect it to a five pole relay to pin 85
pin 86 to ground
pin 30 output to flasher relay
pin 87a possitive from battery.
use a diode between the alarms siren wire and the relay to prevent feedback if you using a factory horn as well as the siren and air horns than use two diodes comming from one siren wire conencting one diode to one relay and the other to the other relay diode stripe should face the relays. this will prevent feedback going to the alarm.
now from pin 30 of each relay you need to add a flasher because this will make the horns honk instead of stay on and will keep the draw down. flashers if you dont have them are available at all auoparts stores. a standard 2 pole flasher

mecp certification is not always needed. I have it and it has not helped me out at all. my experience out shines it.
ok thats sounds like something that i wasnt doing but what type of diode do i need is there a certain number that i need do get and which way do i install it with the bands on the diode facing the relays or going toward the alarm output wire
