DMP Security Alarm Integration


(C L Sanchez 1877) #1

This is really more about “interface” than true “integration”.

I have a DMP XT30 alarm panel in my house. The alarm is not all that spectacular in the HA world, but it’s very good at being a “dumb” alarm system. It is hard-wired, reliable and does it’s job. The downside is it is a proprietary system and does not integrate well with others. It does have an optional Z-wave controller, but I cannot interface it with ST so not of any use for this project.

Now I have scoured these forums for a few months now looking at different options to integrate security with my SmartThings but the reliability just is not there. The Konnected route had the most potential and was my Option A, but requires me to use ST for monitoring (which options exclude fire) and ST is not reliable enough for this application. Great product, great concept, great man behind the vision…but Samsung fails this approach.

Changing the board to a Honeywell or DCS was Option B but this requires more money upfront, an intermediate protocol server (which I could do) and also requires me to leave my local alarm company. The convenience just does not hold the same value as a local alarm company with 7 years of great service.

Let’s add on that cracking wifi just gets easier and a SmartThings account is just one more thing to get hacked. We recently had a house broken into around here where someone cracked the wifi password, got into the alarm interface and shutoff all the sensors and walked into the house without ever disarming the system. Add the common ST outages and uncertainty of software direction and I am even less interested in a full integration. Nothing worse than coming home after a long day of work with a beaten down wife (work, not me) and 4 riled up kids from school and I can’t turn off the alarm.

So I am now looking at my Option C: Build up a Z-wave interface for the existing DMP panel using programable output relays and onboard arming zones.

The DMP panel has an option to add four output relays that can be programmed based on various events. I was looking to set to four relays; one for “disarmed”, an “armed home or sleep”, “armed away” and one for all “alarm” events (fire, burglar, panic, ambush, etc). These output relays would then be wired to a z-wave contact for ST monitoring.

The DMP panel also allows for arming zones. So I will have the installer install 2 arming zones, one for “Armed Home” and one for “Armed Away”. I don’t use the “Armed Sleep” mode. The modes would be controlled by a z-wave contact for ST control. I will also add a zone for “Panic”. I may also add a “Supervisory” zone where I can have non-burglar zones trigger the alarm to contact the monitoring company so they can track me down - good application for water sensors.

With this approach, I keep my separate and independent operating alarm system. I can monitor the system operation via SmartThings and I can arm the system via SmartThings (and automatically via WebCore). The system can NOT be disarmed via SmartThings and in my mind that is a good thing (You have to have a code).

I am still waiting to hear back from the alarm company that the add-on parts I need are available and compatible with my specific board. I also need the electrical details for interfacing the monitoring and control relays. My plan is to use two MIMO2+, which gives me four inputs (from arm/alarm relays) and four relays (for 2 arming, a panic and a supervisory zone).

Hopefully I will have an update on this as it develops.

Which alarm system was that?

Not sure. He was a neighbor of a friend. I had tried to reach out to him to ask if he was willing to provide any details to help others prevent this exact scenario and he never responded to me. The only reason anyone even knew what happened was the whole thing was recorded on a neighbors camera system. Video quality was not very good from a hundred feet away though.

If I had to wager a guess it would be one of the new DIY systems that are wifi accessible.


Rather than using a Z wave contact sensor, you might want to look at ST_Anything. It is kind of perfect for what you are looking at here with the multiple inputs. It’s also a heck of a lot cheaper and more customizable. That would allow you to report back the status of your alarm system to ST.

How would you arm the system from SmartThings? You can’t use a contact sensor to do anything…it’s a sensor. You would need a relay of sometype. Again, I think ST_Anything would work well here using the “switch” capability. A contact sensor would work if the Alarm is changing the state to report back to ST but it’s not going to change anything to arm your system.

With ST_Anyting, you could have all 8 relays wired up to one device that costs around $9 instead of having to but 4 z wave contact sensors and 4 z-wave relays.

Konnected is working on a new interface board which connects directly to your existing panel and allows you to monitor your various hard wired zones. It won’t allow you to directly control the alarm but would at least allow for you to monitor all of the sensors and leverage them within SmartThings. The best part about it is that it works completely independent of your wired alarm panel so that your traditional alarm will work exactly how it does currently.

Thanks @Ryan780, I did not think about the ST_Anything and will look into it.

The feature that is specific to my alarm panel is I can program any zone for arming. I would put a Z-wave relay onto that particular zone in place of a sensor and when the relay is opened, the zone detects the break and arms the system accordingly. Quite simple. I need a few controllable 12vdc dry contact relays, thats it. I will program 3 zones, one for Arming Away, one for Arming Home and one for Panic. I will then have a room called “Alarm” that would have three momentary button devices and each button device would be programmed to control the respective relay. The relay need only close momentarily, which is why I thought about MIMO.

Now the alarm panel does NOT report its status through the contact sensors. Instead, the alarm panel also has four programmable contact relays. For these, I would install 4 z-wave contact sensors to detect these relays. Relays would be programmed as per above. Since my plan was to use the 2 MIMO2+, they already come with both the sensors and the relays on one device. I would only need two MIMO2+'s to get what I need.

But the ST_Anything looks like a great alternate, thanks for suggesting it and I will look into it.

I am aware of the device but I did not know where he was in development. I see this option as supplemental as I can now capture all my door, window and motion sensors. However, as you stated, it in itself does not let me control or capture the alarm stage. In the future though, I could perhaps consolidate some motion sensors.

Any developments on the tie in with the DMP panel? I have an XR150 hardwired that I’d like to explore integrating.

Nothing yet. My HA project is on hold for the moment while I focus on some other things in life. I did discuss adding some arming zones that would be Z-wave triggered as well as some relays that would be wired to a z-wave sensor, but the alarm company will not work with me on this. They sell their own system and want me to go that route. So, I will be moving on from the company, which opens other options. But I am not at a point to take that on right now.

Right now, I am more focused on the lack of reliability of the ST/WebCore before I really invest any more time or money into this system.

But school is starting back up and I need to be focused on the Cub Scouts program for the school and my oldest is getting ready to start flag football, so this may be a while before i circle back.
