Toyota RS3000 to Aftermarket Alarm Adapter

I'll definitely update this thread. I already received the Avital unit and have the wires trimmed and ready to install in the Lutz adapter. I have opened the Avital unit and moved on jumper to select the correct polarity for the install I'm doing.

I will retain the beeper, I prefer that than a loud hooting horn. I had replaced and used 2 beepers in parallel many years ago when the stock piezo died, so will reuse those two.

There's one setting in the Avital that I will change to disable the horn beeping for lock/unlock.

Anyhow, I'll document what I do to install and configure as a reference for anyone that wants some feedback on the product etc.

cheers,
george.
Which Avital unit did you get?
 
I purchased the avital 3100LX model. It does not include the siren and that's fine with me since I prefer the horn. It is the equivalent of the Viper unit described on Lutz's website. The viper and avital are made by the same company - so essentially it is the same unit (again that is also mentioned on the Lutz website).

About $50 on amazon and includes 2 remotes. The remotes are silly expensive, if you wanted to buy 2, it's probably better to just buy a second complete alarm just to get the 2 remotes and have a spare alarm if ever needed :)

Will this setup use the existing piezo buzzer to indicate when the alarm is triggered?

Yes, things can be setup to work that way.
There's a jumper in the Avital that you move to change to (-) polarity for the tail light flash (that pulses during arm/disarm). Then there's a jumper in the Lutz adapter that comes pre-installed that will cause the piezo to beep during arm/disarm. This will emulate the original rs3000 system.

I'll update next week when I install everything.

I never could figure this out and just use the horn. Hope you're well, George!
 
Ok, installed yesterday and all is working. The piezo does not beep. I successfully configured the unit (menu #2) to disable the horn for arm/disarm and got everything setup, but no beep.

I've reset menu #2 to use the horn to chirp on arm (1 chirp) and disarm (2 chirps).

The piezo use to work as of a week or so ago, so I'm doubtful it has failed, but will order a replacement with my next digikey order to verify.

For now it's horn for arm/disarm - it's not too obnoxious since they are very short 'beeps'.

Mounted it under the seat where the rs3000 use to live. Strapped down with a couple of tiewraps as was the rs3000.

I've left the Lutz adapter essentially float/sit on the carpet.

Range is excellent, can arm/disarm the 80 on the driveway from inside/back of the house. No point having too much range since if you can't hear or see it arm/disarm - you never really know if it did...

Anyhow, happy with the final result.

cheers,
george.
 
^ thanks, figured my dual piezos couldn't both be dead. When I can be bothered, I'll look further into how the lutz adapter wires and routes things to the piezo.

@Lutz Auto Any suggestion to what could be going on?

cheers,
george.
 
^ Not as yet. I ordered some stuff from digikey so added in a piezo. Soldered up wires to it and mounted into a holder. Next step is to connect it in place of the old piezo units, assuming they are defective. I did note that I don't have ground continuity to the existing piezo units via the original wiring. Maybe I lost a ground connection. Anyhow, once I get some time to splice the new piezo in I will test and also connect a secondary ground connection if it doesn't just come to life. I also need to follow the wiring to see where it leads after going through the firewall, to ensure it is all healthy back to the original rs3000 connector.

Might take a week or two.

cheers,
george.

The adapter activates the 12v+ side of the piezo. You should be able to test with a multimeter. I believe George tested and the adapter is providing the 12v+ pulses properly. With the jumper on the pcb, the piezo should beep with the taillights.
 
Not sure if this has been posted before, but probably quite useful to have in this thread. At least it shows how an RS3000 should have been port installed.

I'll be checking (and removing if they have been used) the obnoxious splices they are showing in the instructions!

cheers,
george.

The factory beeper is on the firewall above the brake booster and towards the fender. That's where I've seen them on a few port installed rs3000 80s.

I'm off on holidays for a couple of weeks, on my return I'll dig into my non-beeping issue which I'm pretty confident is just bad ground wiring for the piezo via one of those awful 3m taps.

George's location matches where mine is. It's about the size of your thumb.
