Is it possible to rig up 2 alarm systems so if one is deactivated the other still continues to go off? I would want it to all be controled by one remote not 2.

 

Paranoid are we?.. :D ... j/k

You could do it but they would have to be linked together in order to be controlled by one remote.

Where would you install the second? Unless it's in someplace really hard to get into (locked glovebox or engine bay) it's pointless because they could cut those wires too.

Also, if the wires on the first alarm are cut, they could easliy short circuit the relay to the second alarm and disable it too.

Are you that worried about your vehicle getting stolen? these aren't exaclty high-priced vehicles..

Maybe you should get a Glock .45 instead :twisted:

 

u said control by one remote? but two alarms...
u answered ur own question already...
it will have conflict when u hook up to the lock/unlock wires...

u can hook up a back up alarm speaker....that means the alarm still go off even though u cut the wires

 

You can hook up more than one methods of securing your car, such as fuel cutoff, ignition cutoff, steering wheel quick release, alarm, etc. but theres no way, & no reason to install 2 alarms.

 

You can hook up an alarm backup battery with a mini pizzo a loud aedible tone for the inside of the car.

 

Yea I am paranoid lol. I know the car isn't that expensive more concerned about everything in side. Given i have issues with security to begin with cause i know deep down if someone really wants something bad enough there gonna get it. But I been trying to come up with something a little more personal that might be difficult for the average theif. I am afraid that factory installations just aren't going to cut it.

 

This is more of what I am referring to I think. Just not sure how to go about it.

 

I had a two-alarm setup on my former Lexus LS400. . . I was a bit paranoid.
I'm not sure about two aftermarket alarms, but I had my stock alarm work in conjunction with the aftermarket alarm. I was very secretive about how I did this, but now that it's sold. . .

I'm not sure if the OEM Scion alarm should work in a similar manner, as it can be deactivated by using your key to open the door, rather than a remote. And as most car thieves know, it's not very hard to bypass that. If you use an aftermarket alarm, you cannot use your key, as it will set off the alarm, sensing an open door.

I hooked up the lock/unlock wires to my stock arm/disarm wires. I had the alarm brain installed in a custom box in the trunk, which made it look like a part of the OEM electronics. I used a back up battery for the alarm(in an insulated box over the gas tank, behind the rear seats), and had 2 piezo sirens mounted in the interior and 1 in the trunk, as well as the main siren under the hood, mercury switches, shock sensors, the works. To answer your question, this setup controlled both alarms, and when they simultaneously go off, it's quite a light show, as the stock alarm flashes the highbeams, and the aftermarket alarm flashes the parking lights. Both the horn on the OEM alarm sounds and the sirens. And if the OEM is alarm is bypassed by breaking the lock, the other alarm would relock the doors(rearming the OEM alarm). I guess this was overkill, but I was concerned, as Sacramento is the car theft capitol of CA. Most of it was to get the sirens in the interior, to keep stereo thieves out, and make it unbearable for them to find the alarm brain that wasn't under my dash hahahah! I added a final security device, which was an additional manually controlled starter interrupt, which was hidden in the glove box. Yeah, that's overkill, now that I think about it.

Another approach would require an alarm that can "learn" new remotes, but this often means no rolling code technology. . . you could program one remote into both systems, but bear in mind that if for some reason one alarm doesn't sense the unlock command, and it uses the same signal for both lock/unlock, good luck getting them synchonized again!

BTW, I forgot the manufacturer, but there is a company out there that makes special vehicle security stuff (like the electric shock stuff you've heard about). They're mostly illegal in the US, but they have a special model, that releases a non-toxic, harmless, stainless, gas into the cabin. It makes a very dramatic show, releasing a white cloud of gas into the cabin, scaring the living ____ outta the would be thief. . . it's very very expensive tho but it exists.

 

I'd run that back-up battery... I have one on my ride. I can show it to you thursday if you're making the Team NVS meet, but I may be there real late after I get off.

They guy who's askin is in maryland, hahaha but I'll be there thurs and wouldn't mind seein anyway! I don't want to mess around too much with the security on this car. . . even tho the OEM alarm sucks, I don't want to go through the headache of installing another alarm, as this would be the second time in one year! Right now tinting and go fast parts have priority.

 

a back up battery and internal air horns work for me...
you could always add a gps tracking system on your car...
Most cars that get stolen are common affordable cars... hondas and toyotas...
He should have a concern about people stealing it...
You can always connect only one set of the lock wires off one alarm instead of both...

 

Could my altinator handle the second battery?

I don't think I am going to make that meet. Cali is a bit of a drive for me :D

Thanks for the ideas djct_watt. Definately sounds like something I would do/want to do. I rather be paranoid and have to much then be standing in an empty parking spot where my car use to rest saying I wish I had more security on my car.

 

I don't know if I and oneslowxa(man why must you hate, 8.8 0-60 ain't bad!)
are talking about the same thing, but generally most aftermarket alarms can be connected to a backup battery, and are designed to support it.

I'm not sure how adding a second battery to the car itself works tho. . . I needed a second battery for my sound system in my Corolla, but I had a shop install it. I'd think that you'd just wire up the battery in parrallel wiring to the OEM battery, but I'm not too sure about that. I did have an upgraded alternator too, but I think OEM alternators should be able to support it, so long as you aren't running jigawatts of power and activating your flux capacitor at 88mph.

But for security purposes, a small back up battery for the aftermarket alarm system does just fine.

 

Oops! :oops: I may be there on Thursday now. Todays shift was looong. But I always make an effort to see new members.

SWEET!

 

I did mean a back up battery, usually they are ran in series with a trigger to the alarm that tells thehe alarm if the battery is disconnected...

You would need a battery isolater if you were doing two batteries, as well as a charging distributor if you are running more then 2 batteries... plan on ugrading your alternator too

 

I got mine done at Best Buy.
