Alarm auto arming with Turbo Timer

[Trusa]

Just put an alarm in the cruiser and was relying on the auto arm function to arm the alarm after turbo timer cuts out. Unfortunately this kind of alarm only auto arms after it senses the last door closing. If all doors are closed and ignition is turned off after doors closing (manually or by timer) the alarm will not arm, but if you open then close a door it will auto arm.

Really want to sort this out else there is no point having a timer as I'll have to wait by the car to arm the alarm. Only solution I can think of is to use the ignition signal from the timer to operate a relay sending an earth signal to door jam switch, when timer cuts out it simulates a door closing and will arm alarm. But this will mean whenever ignition is on interior lights will be too. Maybe a switch on the relay? Bit of stuffing around tho, especially if the misses is driving it.

Any other suggestions?

Cheers,

Ben

What you have to do is trick the alarm to think the ignition is off. I do this weekly. Alarm work should alway do done by a pro. The alarm is only as good as it is put in. Heres a question for you. how many cut out points and is it an australia standard approved. With some you can change the ignition wire to accessories wire. Note too most pros will not touch it to fix or chance it when done by the owner. Give me a few details, brand, cut out point internal immobliser or relay. I will see if I can help. if two point I will not help. Thats my secret. Thats why I get pay to do it. Plus can be hard extra relays and diodes.

Please note anything I say is only advice. In the industry for 9 years seen it all.

There are probably a few ways of doing this, but without thinking of a whole lot of different ones, the one you've suggested with a relay may be workable without the "lights on" problem you've described, but using two relays - one that is tripped by the door-open signal, and another that is tripped by the turbo timer. Because you are using relays, the signal won't travel back up the circuit and activate the interior lights.

The alternative, depending on how your turbo timer works and how the alarm interacts with the door signals, is to use the turbo timer signal instead of the ignition signal for the alarm. This will only work if the turbo timer signal is always +ve when the ignition is on (and then just stays on for however many seconds/minutes after the ignition is off), and if the alarm doesn't rely on you opening and closing a door to arm itself.

It does all depend on exactly what logic your alarm uses to decide whether to arm itself, so you need to work that out in a step-by-step way.

Damn, don't you hate it when people on a discussion/help forum say things like "I am not going to help you because I am a professional and I have to keep my professional secrets"? Compare that to Exhaustfix's thread in general tech... that's what it should be all about.

Jason,

Unfortunately the alarm does require you opening and closing a door in order for the auto arm to begin.

The two relay suggestion, if I'm understanding it correctly would not work, as the door would be closed when the turbo timer finishes so there would be no signal to the relay tripped by door signal. Did I undestand it correctly?

Thanks for the suggestions mate,

Ben

Well, my idea was that the alarm gets the "door open" signal in two cases:

(1) the turbo timer is still running
OR
(2) a door is open

So when the turbo timer switches off, the alarm thinks the last door has finally closed.

This is just the same as your original idea, except that i was suggesting you add a second relay to carry the door signal from the door switches, so that the turbo timer doesn't "feed back" and leave the interior lights on all the time.

At least, I think that's what your original idea was.

Remember the door actually signals that it's open, not that it's closed.

I only said I would not help if it was two point. Anyone working with vehicles would know what I mean. Most of the time it comes down to ppl trying saving money. RELAX NOT ALWAYS TRUSA. what type of car is it. What brand alarm is it. when is auto does it do locking. Immobilser inside module or relay driven. Black wires or cloured. Any the more info you can give the more I can help you. I was just saying I'm not going to write an SA on how to do a point point.

Trusa PM me and I'll see what I can do. The auto arm only does the Immobilser So any work with the pin switches will do nothing.

Hey chimpboy we meet again. At least now I join the suzuki 4wd club. But ride westgate too cold now. We may meet one day.

Ah, from Captain America's! It took me a while to figure that out.

Sorry if I misread your message, then. Getting a bit tense stuck working with no breaks.

Black wired, internal relay. Auto arm locks doors.

Bought some relays today so gonna try to nut out a solution. Any other suggestions are welcomed.

Well, this is what I was suggesting. A possible problem is that the alarm will see a door closing when the turbo shuts down, but it will never see the door open first - it will be as if the door was open all the time. Dunno.

[Trusa]

No, I don't think it matters how long door "seems" open, as it is triggered by last door closing.

Only potential problem, and this is only a maybe, is the fact that the door is closed and ignition shuts off simultaneously. I'm not sure if the alarm requires a delay between the two. But only one way to find out.

Also waiting to here what Rob suggests.

Might do a test setup of your suggestion Jason and see if it works.

Thanks mate,

Ben

I will be helping ben now, Seeing it is one of my companies alarm and it is in a easy car. The 80 series very common. The main problem are tricking the alarm to arm if the car running. The other is using cut out points other than the starter. You arm the thing car stops. I would turn off auto arm too. If it dose locking to. If I had a dollar for everytime I've heard of ppl locking keys in the car.

On all black wired alarm immoboliser the ignition controls the immoboliser relays. All good will be fix soon. Ben


chimpboy will be at the meeting on wednesday. May catch you there.
