Topic: disable door solenoid when alarm is activ

Subject: disable door solenoid when alarm is activ
Date Posted: February 20, 2013 at 9:38 AM

Ok so I have shaved doors and a compustar alarm system and I want to wire the solenoids I'm my door so they don't work when the alarm is active. Pretty much I don't want to accidentally press my keys and open the door, or someone to fine the backup button on my car and get into it. I was thinking I could do this using relay as my alarm system gives all kinda of pulses and such when I arm and disarm I'm sure I can fine a neg or pos pluse can someone help me figure this out?

You need to use a latching relay from your lock pulse to disable the ground wire from the solenoid.
One relay per solenoid.
A regular relay won't work, it will drain your battery.

Which Compustar system do you have? Depending on the system, and if you have access to an OP500 programmer, you can use one of the POC outputs set for GWA (ground when armed). Then use that along with a relay to cut power from your door popper kit.

Which is exactly why I said don't use a regular relay Kenny, it will drain his battery.

By a latching relay do you lean a relay that just sends a 12v pulse? And how would I wire the relay exactly can you find a diagram?

No, a latching relay is a relay that will 'lock' in place once it is activated until it is de-activated. Think of it like a toggle switch. It receives one signal that will turn it on and won't turn off until electrically 'told' to shut off.. but won't draw power once latched.

Hopefully that made some sort of sense... lol

Can do you explaine to me how I would wire the pins?

No.
Go to Mouser or Farnell USA/Canada sites look up 12VDC latching relays, dual coil SPCO or DPCO download the data file. I'll do a diagram, wait about an hour.

First, what's your native language?
Second if you don't have outside push buttons why do you even need this, it's an unnecessary complication.
If they force your doors or break a window your alarm will go off if correctly installed.

It would actually be safer all round to use an aux output timed to give them power only when the alarm is disarmed for about 1 minute.
And then wire them through the ignition.

My native language is english.
The purpose of this is because sometimes I accidentally press the buttons on my keys and open the doors while I'm not at the car. The alarm dosnt go off when the pooper pushes the door out, it dosnt push it far enough for the door jam switch to move only when you open the door the rest of the way by hand or if the shock sensor goes off.

I also have an emergency switch located under my rocker ( typical spot)
My aux output are all currently being used
Thanks do much for the help!

I can disable the buttons on my remote but it's an awful pain and I forget to most of the time lol

You have used up all 9 POC outputs??? Damn, what are you running... lol. I thought I went nuts on mine and I still have 3 or 4 left.

No I have the cm3000 and I have 2 aux output and I need a seperate modual that will add another 7 aux outputs, but I would rather not purchase this at this point just for the purpose of disabling the solenoids.

Also what is POC?

I actually just found this thread.

It seams to be what I want but it's awfully complicated. I like howies idea on using the latching solenoid, it seams a whole lot simpler

Programmable output. It's only on the newer Compustar modules. Basically there are 9 wires that you can choose what they function as.

Make those buttons only work when the alarm is disarmed.448_latch.bmp
Interrupt either the 12V+ or ground wires, you will need one each, 10amp rating for each door.

I've modified that drawing assuming you have NEG (-) output lock wires:-

I don't really understand what wires are what on the diagram, the black lock, unlock wires are the disarm and rearm wires that give the neg pulses ?

Okay, where do I connect the input/ output wires?

Across each solenoid's power feed.
Frank, I told you so.

So it dosnt matter what ones input or output because either way the switch will be open or closed? Current will flow both ways?




Posted By: guitar_freak
Date Posted: February 22, 2013 at 12:14 AM
Are you sure 10 Amp will be enough? I'm going to be installing probably a 30 amp self resetting fuse/breaker on the wire going from my battery for my poppers. They are rated for 50 lbs and draw alot of current and my interior lights always dimmed wen I had the power wire tapped from my wire harness when I popped my doors. And I'm using 20-30 amp relays to convert my neg aux pulse. Also is a dual coil latching relay something I could find at a install shop or auto parts store? And do I need a dual coil because I have seperate arm disarm wires?

Thanks so much for explaine it to me so well and the diagram I'm stil learning an I appreciate the help!

That's what worries me and I've already told you to browse Mouser and Farnell.
Easy answer use one of these relays as an SPDT as in the diagram then instead of running the power through, run your aux triggers through then current draw (200mA) won't be a problem. Note the diagram shows a relay with TWO switches. I've modified it so instead of breaking power or ground, you're now breaking the two (one for each side) aux wires from the R/S to the relays.

So the pink and blue colored wires are for the 2 aux outputs?theirfore I would only need one relay for the two doors? And I would Inturrupt the ground pulse before I convert it to positive pulse?
Also I was wondering if I could find a latching relay at a parts store cause I would rather that then order it from the Internet and have to wait lol

Also what does R/S stand for? Lol




Posted By: howie ll

Twin coil DPDT 12VDC latching relay.
And no unless it was an electronic parts store.
Yes to the aux.
And yes to interrupting the ground pulse.
And yes to only one required.
R/S = Remote start.

This is now getting silly, I wouldn't have to give my 15 year old grandson this much help.
Doubt if you can buy these over the counter.
Google to Digikey.
Enter Latching relays.
The next page gives you the choice of signal or power. Chose power or high power.
Apply filter at top, 12VDC, dual coil latching, DPDT.
You will then be given a page of choices, any of going down the page, numbers 1, 2 or 5.
Right hand side gives you data sheets with layout.

Your a good man I appreciate you being pacient with me anf lay everything out do simple for me
