Re: Connecting two DMP alarms together? Outputs to Zones? Possible?

["Jason Millard" <jsm174@xxxxxxxxxxx>]

Hello again.

Oh boy. It looks like my previous posts (submitted via Google)  finally made
it to the group about todays after I had sent a better thought out post. So
I'm sorry about  people having to duplicate there answers.

I'm now using Verizon newsgroups directly inside of utlook Express, so this
will never happen again.

Some one asked how would a DIY get DMP products? Well to start off, when I
built my house, I asked the contractor for an alarm system. The system was
never installed, so I was left with a pile of parts. DMPs website provides
PDFs for all of there products.

I realize that statement is just a comment, but I never gave DMP products a
bad rap. I may not have the electronics aspect down, but the programming is
actually pretty darn simple.

So someone also mentioned, that getting a XRSuper6 cost more money, etc.
Well, actually I purchased a brand new XR20 off Ebay for my personal system,
so I had the
XRSuper6 laying around collecting dust. I almost resold it on Ebay, but I
gave that to my brother to use with his XR200.

I should have done more research on the XR200. After the fact, it does seem
like an awesome panel. I didn't realize it could be partitioned and armed
separately etc.

Also (to my defense) we didn't have any 790 keypads just 690s. So we would
have had to wait and purchase a zone expander. And since the only way to get
parts is via EBay, who knows how long that would take to show up. I know,
there are currently two on there now. Never fails :)

Anyway, we're still going to go use the XRSuper6 in the garage. Everything
is already installed, so we really don't want disconnect everything and
start over.

We decided to get an 860 Relay Module, and an additional 305, and tie the
N/C contacts of Relay 1 and Relay into the XR200 as Zones 7 and 8.

When the garage goes into burglary, output 3 goes active, opens the relay,
and the XR200 goes into alarm via zone 7 and the house keypad displays
Garage Burglary.

If a fire is detected, output 4 goes active, opens the relay, and the XR200
goes into alarm via zone 8 and the house keypad displays Garage Fire.

Again, I realize that this is not a correct solution, but it should work.
Our system is unsupervised anyway.

I also understand the higher risk of lightening. A little better for us, the
wires were run way underground years ago.

Thanks for all your comments and answers. I really appreciate it!
