MrRonFL,

I would like to ask you how can I use a PGM output to open or close my garage door?

I have ordered the Wireless Receiver and a Wireless Key and would like to use one of the buttons to trigger my garage door..

Can you please give me your advise on this?

Thank you in advance for your help

A lot depends on the capabilities of the garage door opener, and how comfortable you are with a semi complex bit of wiring. The simplest way, if the opener has a simple switch input point, is to use the PGM to trigger a relay to trip the opener. You can program the remote button as a command input to activate.

There's several steps, both in wiring and in programming.

 

Well I feel pretty confortable in doing this.
I have a Chamberlain LiftMaster and it has 2 contacts that I connect a switch to for inside the garage.

I did not know if the Power832 system could trip this or if maybe I needed to use a relay to connect these points.

I am not sure of the voltage needed by the garage opener and if the PGM outputs could actually trip the contact without causing an overload on the DSC system...

Can you outline a few options for me?
Also, what should I program the outputs to be in the PGM programming section?
Which PGM output should I use ? 1 or 2 ?

--Mike

 

I would recommend using a relay. Anytime you are connecting an alarm to a higher powered device you want a relay for isolation's sake. Since these are switch inputs, you have no choice. The PGM terminals do not act as a "dry contact".

It doesn't matter which one you use. They can both be programmed for the same range of functions.

For this purpose, you would be programming it to use one of the command output commands. (*71, *72, *73, or *74).

This is where you are getting into "soft" areas. There are a lot of variables between what the door opener requires, and how you actually want the thing to work.

 

MrRonFL,

First things first, thank you for moving this to a new thread and not making an issue over it. I apologize for starting this topic inside the other and should have known better, since this is not my first forum experience. I will make sure not to do this again in the future.

Now back to this topic..

I am familiar with using 12v Bosch relays for auto alarms and automatic auto locks on older cars. Would this be a good relay to use ? If not which one should I use ?

I will be using PGM1 since it is not in use and is already pre-programmed for *71 output function. I know I need to use the PGM1 output as switched ground and the Aux+ and the power for the switch part of the relay. I will use the 2 wires from the garage door opener to connect to the relay for them to make contact whenever the relayed is switched. I only want the garage opener to act as if I pressed the switch inside the garage, nothing very fancy. This way I can use the wireless key and not need to worry about my garage door opener.

I want to thank you for taking the time to explain this process to me.
I also wanted to say thank you for helping me gain a true understanding of the programming of this system. I understand the layout of the programming manual and worksheets quite well now. Thank you for taking the time..


Please let me know if my understanding of this process is correct and which relay I should use to accomplish this..

--Mike

 

Yup, that's the ticket. It should work using that configuration.

So long as the contacts in the relay can handle the current that passes through that switch leg (the minimum requirement is probably in the manual for the door opener), it should work just fine.

(I split the thread off because it had spilled over to another page, and someone else also asked about the same trick).

 

Any suggestions on a relay ?

Thank you for being so helpful and willing to share your knowledge


KUDOS MrRonFL

 

I usually buy the ELK 912 or 924 relay. Altronix and System Sensor also make very nice relays. Heck, I've bought the ones Radio Shack sells when I was in a hurry.

 

Thanks MrRonFL..

Do they come with wiring diagrams?
I would assume they do.

Have a GREAT Day

 

Yup, and you can download them ahead of time from the manufacturers websites.

 

Got them.. Thank you MrRonFL....
