Long range secure radio key with two relays?

Anyone suggest a long range wireless keyfob - reciever that could be used for securely arming and disarming a couple relays that would ultimately go into a a couple of zone inputs in my ELK M1.

The keyfobs I have at the moment you have to be at the gates and only then it just fires the open commands.

It would be nice to be about 100 mteres away and be able to securely fire the relays either open or closed. Something with a rolling security code so I know the system is not going to fire with some spurious RF.

Anyone using or know of such a system?

Hi,

This system might suit your needs. The extra module that you have to add to get the extra range is a bit of a kludge & you may need to mount it permanently in your car rather than keeping it on your keyring.

Maybe this would work? I am not that familiar with it but I think the receiver has dry contacts for outputs and you could have multiple fobs....

Here in the states, they sell universal garage door opener kits. They basically give you a little black box, and a remote, which can talk to each other using secure/rolling codes, and the box interfaces the garage door opener by tapping into the door opener button wiring (so you could drive a relay). They aren't that cheap, but it would work. Here's an example:

Maybe you can find something similar over there?
 
Thanks for the feedback guys....appreciated. The Oatley Electronics solution looks interesting.

Like the idea of having the TX installed in the car, not sure how you would interface the keyfob with the TX434A long range TX. The info is a little thin but for the price I would just buy a set of modules.

Hi,

The info is there on the Oatley site, just a little hard to find. If you click the second "PDF" button on the page it shows the connections. Basically you need to connect 3 wires between the two modules. Two for power and one for data.

Thanks for that Paul..Regards Fleetz
 
Fleetz,
In Aussie land, Ness Security has the keyfobs and wireless receiver that works directly into the M1. The keyfobs use the Ness protocol which works very well. They also have a standalone relay output receiver for gates.

Hi Spanky,

Thanks.

I have the Ness M1 wireless RX and their 4 button keyfobs all works expect in my application and more the case our location here I need more than the Ness keyfob range can offer. At best line of sight you have 30 metres range. I have the RX mounted in a ABS housing near the top front of the garage the closest I can to our car access. Then you are in a moving car trying to fire off a open command coming around our corner which gets quite busy and wanting the sliding gate open and panel lift door open. Have to turn right into our place and of course yield to trafficc coming from the opposite direction. We are about 30 metres from a Tee section and people come flying around there and if we are hanging in the road it is only a matter of time before we wear one up our arse! (Bare in mind in the above description that we drive on the right sige of the road over here.....the left!!!! :angry: :) :P

That said we do need to be able to fire the we are home command probably at least 120 metres (360 feet) to give the gates/door time to activate. there still is the chance we have traffic coming from the other direction however no too often, if the gates are not open then we are continually exposing ourselves to that rear end experience.

I like the solution FrankMc pointed me to (thanks again) an Aussie company http://www.elsema.com/index.html they have the hopping codes TX and RX which will give me the security I require. I would locate the RX close to the M1 system use one of their long tange antennas on the RX and then select the appropriate long range hand held TX. I would then use some unused zones to take the RX relay or open collector tallies to do what need to be done and probably because of the hopping code arm and disarm the M1 too

The convenience of the Ness keyfob dissappears as Elsems's remotes are quite a bit bigger. Elsema also have TX's that you could mount in the car and then fir a couple of push buttons to activate the open close function. Exploring that as well.

Sounds like you have a workable solution, but I'll throw this one out there anyway... What I do is use a Garage Door interface for my Clifford car alarm (I'm sure many alarm makers have these - they're just not standard-stocked items - they're used in higher-end installs to add channels to their car or to run home systems).

http://www.caraudio-caralarms.com/519H.html
It has 3 channels (channel 3 is pressing both buttons at once) - the first one has a built-in relay, then you add your own if needed for the other two (going into an M1 you wouldn't need to).

I don't like to leave things in my car that control my house - so I've used these for about 10 years now... On the keyfobs for our cars, I just program 2 channels on the car alarm remotes for the garage doors - and the unit comes with 2 remotes as well - one is on my motorcycle keychain, and the other is laying around the garage.

The benefit is that I never have anything left in my car that can let someone into my house - but since it's on my keychain, I always have a keychain remote on me - I use the 2 channels for the garage doors, but am debating hooking the 3rd into the M1 for some kind of automation (haven't decided what needs it yet).

Just another option...
