turbo timer & alarm, how-to??? Options

[Defgeph]

I have a Apexi turbo timer and a DEI model 300.

Anyone know how to hook this timer up so that it works with my alarm ?

Thanks

Well, for the turbo timer, hook it to the two ignition wires. Then for the alarm's ignition wire, I'd hook it up to your accessory wire rather than an ignition wire.

Then for the ground wire on your sensor(s), hook it up to terminal 87a of a SPDT automotive relay. Terminal 30 and 85 go to ground, and terminal 86 goes to one of your ignition wires(either one will work.) This way your shock sensor won't get power until the car is off.

Do you have any specific questions about the install?

I have a similar combination, what I did was was disconnected the ignition wire from the alarm system. It eliminates the feature that prevents the car from being driven if broken into though.

You could always install a fuel pump kill, clutch switch kill, starter kill, ECU kill, or something similar using the grounded output when armed wire.

I have an alarm installed already. I'm wondering how to use my turbo timer with my alarm.

How do I set the alarm while the turbo timer is doing its job ? Is that possible?

For example, I would turn the key to the off position. The turbo timer would leave the engine running, I would get out and set the alarm with the engine still idling.

Thanks

Like I said in my post, you can modify the alarm wiring to use accessory power for the ignition wire. Then you can use a relay like I described to prevent the shock sensor from going off due to engine vibrations.

HAHA, I read ur post and got totally lost.

Once I figure everything out I know it can be done now.

I guess I can search DEI and find out which wire go where.
Or should it be easy to notice where the wires go ?
I have never messed with an alarm before.

Thanks Chris,

OK, I'll make it a bit easier to explain.

Your first step should be to find an installation manual or wiring diagram for your exact alarm. Now, figure out if you can arm your car while it is running. Most alarms won't arm if the car is on, but a few will. So test this...just see if your car will arm itself while the key is in the on position. If it lets you do this, great! You can skip the next three paragraphs. If not, read on.

Go through it and find out which wire from the brain is for the ignition power. Now, this wire is most likely already connected to one of your two ignition wires near the ignition switch or the driver's kick panel or the interior fuse area. These wires are most likely blue/red and black/orange, but test the wires with a voltmeter to be sure. Ignition wires give +12 volts when the key is in the on or start position.

Now, once you've figured this out, you want to remove the alarm's ignition wire from the factory ignition wire, and instead splice the alarm ignition wire into your car's accessory wire, which is grouped with the ignition wires and is most likely gray. But again, be sure to test with your voltmeter. The accessory wire will give +12 volts when the car's key is in the acc or no position, but NOT when the car is in the start position. The best way I've personally found to tap into these wires is not to cut and splice or use a crimp-on connector, but rather, take a razorblade, carefully slice off a bit of the insulation all the way around the wire, and then twist your wire you want to add on onto this wire tightly. Then solder the area and wrap it in good electrical tape. 3M Super 33+ is my tape of choice by far...expensive, but worth it for most wiring situations.

Once you've done this, you will now be able to arm the car when it is running. Just make sure that if your turbo timer has an accessory wire that it's not hooked up to the car's accessory wire.

Now you've got one issue down and the car will arm when it's running...perfect. Except for the fact that the shock sensor will detect vibrations due to the engine and immediately trigger the alarm. Not good. The solution is to prevent the sensor from getting its necessary ground until the car has stopped running(and stopped shaking...because the car doesn't immediately stop shaking when ignition power is cut...the engine turns off but the car will shake for a brief little bit once this ignition power is cut.)

Look in your alarm installation manual again. If your alarm has remote start capabilities, there may be a wire that gives a ground output when the remote start is running and for a couple seconds after it turns off. My Autopage RS-650 alarm labels this wire as "Start Status Output," and this wire gives ground when the car is running with the remote start and for three seconds after the remote start turns off. If your alarm has this output, you're in luck. Simply cut your sensor's ground wire, and connect the sensor side of the wire to this wire from the alarm brain.

If not, you're in for a bit more work. The only way I could figure out how to get this to work involves a DEI 528t timer relay(available on eBay for $20 shipped or so.) Basically, you connect one of the ignition wires to the black/white trigger wire on a DEI 528t. Then connect the orange wire(normally closed) of the DEI 528t to the sensor side of the ground wire for the shock sensor. Then connect the yellow and black wires of the 528t to ground, and the red wire of the 528t to a fused constant +12volt source. Then cut the blue loop on the 528t, and turn down the 528t's knob as far as it goes(counterclockwise.)

Now your shock sensor will get a ground signal whenever the ignition is off(except for the first three or so seconds after the ignition is turned off), so your shock sensor will no longer be on when the turbo timer is running, setting off the alarm. If you need any more help just let me know.

Thanks Chris,

I can set my alarm while driving. but I dont have remote start, or the option to have it. So I will need this relay.

Thanks alot this was a huge helping hand.

Edit: if you ever get an archive going, this is a perfect thread for it.

Autostart as in remote start? Just read through my instructions and figure out what your alarm can and can't do and then follow my instructions accordingly.
