HAI Omni IIe Electronic Deadbolt help please

[rerunblue]

I built a new home last year and performed a self install of an Omni IIe. Everything has worked great, but I recently ran into a hurdle I can't seem to overcome. I'd like to be able to control a magnetic deadbolt from my keypads (and remotely via my HAI enabled smart phone). Thus, I purchased a normally closed deadbolt and installed the bolt without any problems. I connected the power supply and control lines to a prewired four conductor wire which terminates at my control panel. The deadbolt draws 900 mA, which is too much for outputs 1-8 on the board. Therefore, I connected the power directly to the 12V output and the control lines to one of my zones. However, I cannot figure out how to program the the panel to open the lock. I believe the lock is functioning because it opens when I touch the control lines together. So, I guess I'm asking if anyone knows how I can program the Omni to accomplish the same thing. That is to say, assuming I'm running 12V of current to the bolt, how can program this zone so it closes the circuit when the system is not armed?

Any help is appreciated. Thanks in advance.

A couple of quick things:

1. A schematic of the lock circuit or explanation of its operation would be helpful. (e.g. 12V on the green wire locks it, 12v on the brown wire unlocks it)

2. When powering high power devices you should consider an auxiliary power supply. Just make sure that all auxiliary supplies share a common ground with the Omni.

3. I suspect the solution is going to end up being something involving our relay board connected to outputs. Basically the output will control the relay and the relay will switch the high current load which is supplied by an auxiliary power supply. This is fairly common and relatively easy to do.

Start with more info about how the lock works.

Thanks for the reply. My account is fairly new so the administrator won't allow me to link directly to the schematics. However, the deadbolt is a a NC unit with four lines running from the solenoid. Two of the wires are intended to connect to the control panel. They are stranded with white sheathing. The other two lines connect to a a 12V power source. They are also stranded, one is red and the other is black.

When power is supplied, the plunger extends from the lock. When power is cut, the plunger retracts. I believe the controller lines are designed to provide feedback to the panel when the door is opened or closed. That is to say, the deadbolt has a built in magnetic contact which acts like any other door contact. The only way to retract the plunger once the lock is powered is to touch the control lines together. Hence, I was wondering if there is a zone or output on the Omni board that will essentially close the circuit between the the contoller lines when commanded.

After thinking about this issue last night, I came to same conclusion as you regarding the relay. I've never used one before and am a little shaky regarding the mechanics. My understanding is that the relay would connect to an output on the board and I could then power the lock via the output. Do I use the relay in conjunction with an external power supply?

Thanks for your help. I really appreciate it.

How about the make/model of the dead bolt? I can probably google the manual...

It's an off brand from China. The instructions were one page and written in Mandarin, so I doubt they'll be of much use. I purchased the lock off of ebay. You can still view the bolt on ebay by searching item # 150680122434. Thanks.

Not sure why this would be so difficult. Obviously if shorting the two white wires opperates the lock then all you need is a relay and use an output to control the relay.
Other than that, is there another question you have about it?? Maybe I'm missing something here.
