Thread: Adding indoor (home) notification to Car Alarm...

yeah i dont know. i wanted to do something like that, but have my remote unlock my house doors

Is this possible? I can either buy something, or the parts to build one.

Yes.

More than likely it will end up costing you just as much to make something as it would to simply buy a new alarm.

That said, you could open your remote, find whatever it is that vibrates and/or the thing that makes noise. When the remote recieves whatever signal it recieves, it turns those both on. You could run wires from the same place that turns both of those on, to a relay.

I'm not saying to take apart your remote and run wires from it, because obviously that would be stupid. You could do something creative though, like making a dock for the remote. That way when you set your remote on it, prongs from the dock touch the correct spots, and wire up the relay.

The relay could then turn on any number of components you wanted. I realize this is for the house, and not the car, but the same idea applies.

I would buy one of those kits you see that have a keychain and a little receiver with a relay. Actually radioshack used to sell them, i'm not sure if they do anymore. But you just use one of the outputs of the alarm to trigger a little relay to simulate pushing the button on the remote. Then you could attach anything to the receiver in the house, strobe, alarm, coffee pot.


edit: found it, but it's discontinued. Call stores I bet someone has one still hanging around

That seems like a better pre-built solution then what I suggested. Anyways home depot carries the same thing, and i'm pretty sure other hardware stores would too.

I have the same situation as you... what I did was build a module... it consists of another cheapo alarm brain, mounted in a tiny enclosure... this is a $29 passive alarm module, it sets passively, no remote even... inside the enclosure is just the module & a 12v adaptor & a 12v piezo,this goes under my night table. there are 2 wires coming out of the module, one is the plug that plugs into the ac outlet for power, the other is a harness that extends around 4'.... it consists of a tiny shock sensor & 2 switches... a push button & a toggle.... this is mounted in a tiny nice looking box/pad that I rest my remote on..., on my table right next to my bed...

goes like this.... at night I place my pager in vibrate mode on the box/pad, I throw the toggle switch... this arms the cheapo alarm, 30 seconds later one chirp from the piezo tells me it's set.... if my pager goes off in vibrate, the alarm activates by being tripped with the shock sensor & the piezo screams.... in the morning I throw the toggle(ign on) & then press the red button (disarm)

the only time this is any kind of problem is if I knock into the thing by accident, then my wife wakes up & screams at me... other than that, no problems the whole thing should cost $60 or so to build & is real easy...


the only thing I have been meaning to do for a while now is to build the shock sensor & switches into an alarm clock, or the base of a lamp, so it's invisable... still use the external module under the table, but use the alarm clock as the cosmetics so you don't have to see a box/pad on your table.... never got around to that yet though...

turbocad, great idea! This sounds very easy.... The alarm I replaced would be perfect for this. Thanks!

What do you guys think the range would be on those RF keychains suggested?

depends... regular fm ones viper/clifford/python... most really, range is a block or 2 may be depending on terestrial blockages...

then theres fm spread spectrum.... these have 2-3 times the range...

if you build this thing it is friggin awsome.... one day I had a friend over, car parked outside.... someone bumped my car... the piezo started screaming... he was like, "wtf is that", I said, my car, then went outside to see a girl parking behind me.... my alarm didn't even go into full alarm, just the primary shock sensor tripped... he was floored by this!!!

this add on is good enough that it should be part of a complete security package for anyone with a pager alarm... I thought about building more & selling them... but no time

That is a good idea!
More than likely though, i'd stagger home drunk just once, bump into and then break it after I couldnt get it to stop
