Thank you for your prompt replay and for your help. Appreciate it.

DPCO is Double Pole Change Over, which is equivalent to DPDT relay according to Wikipedia http://en.wikipedia.org/wiki/Switch,but thats not an issue i can get the same DPDT which you used.

One thing im not understanding here is about the reed switch, when the reed switch is on the circuit is on, but as soon as you remove the magnet the reed switch will turn off which will turn the whole circuit off, isnt that correct? or the reed switch stays on after i remove the magnet? if the reed switch would turn off after you remove the magnet then how will the circuit remain on?

Thanks once again for helping me out.

Kind regards,
Yazen

 

Once the reed switch is activated, it stays activated until you push the reset button.

 

Or the battery is disconnected.

 

Thank you so much, this explains everything! Appreciated sir

You very welcome. Enjoy.

 

Will try and build the circuit over the weekend and would share the picture with you guys!

I have an idea to improvise the device and would like to share it with you for your opinion and suggestions, if i install a time delay relay before the rest switch and hock it up with the door switch, and set it the timer to 2 minutes, wouldnt that be a good idea, so the scenario would look like this:

Get in the car, swipe the magnet, device is activated now, when i open the driver's door, the door switch would trigger the time relay and after 2 minutes the time relay would activate the rest switch and the car would turn off. This way i dont have to press the rest switch every time i left the car, and its good in a way if someone forces me to leave the car, so i leave the car, the car will shut down in 2 minutes. This way i dont require LED. What do you think?

Thanks, Yazen

 

I would keep the LED both as a deterrent and so you can see when you have successfully activated the reed switch.

As far as the door switch triggering the reset, I live in a warm climate and frequently start my car with the door open, so that wouldn't work for me. Also if you ever open your door for a second for some reason, like to let your dog into the car after chasing him around the neighborhood or say if you dropped some change at the drive-through, or you switch drivers with the car running, your car will die 2 minutes later. Then there would be the servicing issues.

 

Thank you for your reply. Actually, you are right, its not a good idea! what iam trying to achieve here is to get the rest switch to be activated automatically, maybe i can connect it to the ignition switch and whenever the switch would turn off it would trigger the reset switch! what do you think?

Regards,
Yazen

 

That would be better than the door switch.

 

Hello guys,

I finally bought all the items, bench tested it and it worked pictures of items attached here.

The only question i have (for now ) is that, how to hook up the reset switch with the ignition, so that as soon as i switch off the car, reset switch would be activated to arm the device? i guess it requires a relay! but which kind of relay is it, i dont know guys your help is needed please.


Thanks again,
Yazen

 

I like my immobilizer the best. You cannot start my car without lightly tapping the right side of my shifter

 

NOW we know his 1 WEAKNESS, HAHAHAHAHA (evil laugh).

 

THANK YOU! Sorry for shouting but I have been searching for a clear wiring diagram for this system & you provided it.

You're welcome, James. That was my intention.

 

Did you use a momentary switch to set the alarm? I have a press on (close), press off switch (open) & I have to press the switch to off (open) & then swipe the magnet to disarm system.

It sounds from the original operating instructions that you can have the system armed & simply swipe the reed switch to disarm the system.

please advise.

thanks J.

Just noticed you live in Sarasota, FL. Almost moved there with my Colombia born wife. (now ex-wife) We searched from the Cape, around the horn up to Tampa, liked Sarasota the best.

 

RE: the reed switch. I one have has three connections. a feed (input) post, and two output posts, one of the output post is active when magnet is away from switch & the other is active then magnet is close to switch. If I remove magnet it changes posts. Have it connected to pole that is active then magnet is close to switch.

Did you use a different kind of reed switch that stays closed even if magnet is taken away?

thanks
J.

 

This is a pretty cool Idea and i might just put it in my car

 

Going to use it to control Main feed to Ing. Switch & feed to electric trunk lid.

 

Love Sarasota...been here since 1996.

 

It is from a window alarm.

 

I love it, 666. Still works great.

 

That sounds awesome.
