How to send door strike commands to open door

[dzirkelb]

I have a door strike, model 7130 by Adams Rite Manufacturing Company, which opens a door (or at least it used to).

I am custom developing a Daycare application and I need the ability to punch in a code on a device. If the code is in an sql 2008 database (which will be housed on a sbs 2008 server), then the door will open.

I haven't a clue on how to send a command to open the door progromatically. If there is a general canned program out there that can open the door as a test (like, double clicking the program will open the door), then that will work also as I can call the program if a successfull code is entered.

Currently, the door strike has no connection on the other end, meaning, it has two bare wires which will need to be connected to either a usb or serial port, either is fine, but would prefer usb.

I called Adams Rite Manufacturing and they basically told me to contact Honeywell. They basically told me to contact someone else.

I am willing to using someone else's program or hardware (opposed to placing a touch screen cpu on the wall), just as long as it will integrate with my sql 2008 database.

Does anyone have any ideas on how to accomplish what I am looking for, or where I can call to get answers?

Something like this? http://www.grainger.com/Grainger/items/2EUU8?Pid=search

The door strike needs power to open. If it's like the one linked, 24 VAC or 12 VDC. It doesn't have any internal smarts. When power is applied it opens, when power is removed it locks. So you need a power supply and a relay to control it. The relay is what the computer will need to control. There are lots of ways to do this, e.g. if you want to use Insteon you would use an IOLinc http://www.smarthome.com/2450/I-O-Linc-INS...n-1-Out-/p.aspx while if you want to use X10 (probably not for door control...) you would use a universal module http://www.x10.com/automation/um506_s.html If you don't want an automation system, you just want direct USB control you could use something like http://www.sparkfun.com/commerce/product_i...roducts_id=9669

Great info! If I go the insteon route, then how would I send a signal to the controller to open it? I see the straight USB could be a good option also.

And ya, the first link is the door strike we have

If you went with Insteon and you wanted to control it from the computer I would use a powerline modem (PLM) e.g. http://www.smarthome.com/2413S/PowerLinc-M...ual-Band/p.aspx (There is also a USB version but from many reports it seems the serial version is more stable. I use a usb-to-serial adapter with it.) Info and links about programming for the PLM: http://www.madreporite.com/insteon/insteon.html

You could also use a SmartLinc with custom commands. This is less flexible but would be easier to code for, since you just need to use a properly coded URL to trigger an event. http://www.smarthome.com/2412N/SmartLinc-I...ntroller/p.aspx Some info on custom commands: http://wiki.smarthome.com/index.php?title=...ds_in_SmartLinc I haven't worked with the SmartLinc but there are plenty of people on the Smarthome forums who have. http://www.smarthome.com/forum/

I'm sure others can suggest methods using other automation systems, I'm just limiting my comments to what I know.
