    One last thing and my EZIO6I will be all setup.

    http://www.alarmeengros.com/installation15P.pdf

    On page 17 (2-11), figure 13, how would I interface the wires (1-4) with my EZIO6I? I can handle the alarm programming from the keypad, but have no idea as to where I would hook the wires from the alarm to the inputs (I1+,I1-, etc.) on my EZIO6I?

    I would appreciate any feedback.

    The document you referenced does not provide me enough detail to know how to use the connections…

    pin 1 = output number 17 (trigger 1):
    15 ohms to ground when closed (output
    low), open when off (output high, normal
    default); can be used to reset smoke
    detector power (must set “output normal
    low = yes” in *79 Menu mode, and set for
    zone type 54, fire zone reset, in *80 Menu
    mode); or can support 12V relay module†
    that draws less than 100mA
    pin 5 = output number 18 (trigger 2):
    100 ohms to ground when closed (output
    low); open when off (output high, normal
    default); or can support 12V relay module
    that draws less than 20mA

    If you have a voltmeter and can measure what the alarm system is providing under the various conditions, I should be able to tell you if that will work with the inputs. The voltage requirements of the EZIO6I are well documented. What is missing is the voltage detail of the alarm system. Have you looked at the manufacturer of the alarm system, perhaps they have a forum that can provide the missing information. I would not attempt to connect any of the alarm system pins to the EZIO6I inputs without understanding the voltage data for the respective pin.

    The document you referenced does discuss a relay module that can be connected to the alarm system. Fig 11 shows four relays with Com/NC/NO connections which could be used.

    I will check with a voltmeter later tonight. I know the 4204 relay module will do the trick, but was trying to avoid it since I think the 2 on-board triggers will be sufficient. I will update later tonight with my findings.

    OK – I replaced the X10 Ademco transformer with the standard, and reprogramed my “triggers” for Stay mode to point to output 17 (pin 1) in Figure 13. When I “Arm” the alarn in stay mode and I have my meter on pins 1 and 4 (output 17 and GND), I see the voltage jump from approx 17-19 down to next to nothing 0-0.5. and it reverts when I disarm the alarm. Does that help?

    Pin 4 to I2- and pin 1 to I2+. The EZIO6I spec says 3-30 for an ON condition. The 17-19 does not exceed the maximum and the 0-0.5 should be low enough to be outside the active range. My expectation is that Arm will turn I2 OFF and Disarm will turn I2 ON.

    EDIT: I assume the values you gave were DC volts.

    Perfect – I hooked both outputs – 17 & 18 – up to I2 and I3 and now have alarm monitoring. Thanks again for your expertise. I know just enough to make me dangerous. Have a great weekend.

    Spoke too soon. Something about Output 18 (Pin 5) is different. It looks like it fluctuates around 0.5 disarmed and 0 (no fluctuation) when armed. I was going to map Output 18 to AWAY mode.

    Output 17 is mapped to STAY mode an is working just fine. I sort of assumed the hookup would be the same, but even the description in the manual that you copied pasted seems slightly different.

    Something different between the two outputs, pin 1 says it can source 100 ma, pin 5 can only source 20 ma. Disconnect pin 5 from I3 and measure voltage between pin 3 and pin 5 as you arm/disarm.

    I am getting ‘0’ between 3 and 5 both armed and disarmed.

    Figure 10 shows pin 5 driving a LED connected to pin 3. That suggests to me that pin 5 may need a different programming option to cause it to present the needed voltage swing.

    Strange. I programmed it identical to output 17. I just ordered the 4204 relay board you mentioned off eBay and think that I should have far less trouble going that route. Thanks again for your help.

    Could even be a hardware issue with the circuits behind pin 5. The relay module looks like it connects with the 4 pin communications connection and pin 5 does not appear to be part of that interface. I agree with you that the relay approach should be less trouble. When everything is finished post the final results. Nice to let anyone following the thread know how things worked out.

    grif091 – I got the 4204 Relay module in the mail today. I will be hooking it up later tonight. I have the hookup to the alarm panel figured out, but was wonder how each relay will interface with the EZIO6I. Each relay has NO, NC, and C.

    Connect I2+ and I3+ to 12V on EZIO6I. Connect GND from EZIO6I to C on Relay 1 and C on Relay 2. I picked Relay 1 and 2 for sake of example, could be any 2 of the relays you chose to program. Connect NO of Relay 1 to I2- and NO of Relay 2 to I3-. When Relay 1 is energized, I2 Input will be ON. When Relay 2 is energized, I3 will be ON. If you want the opposite Input state when a Relay is energized, use the NC closed contact rather than the NO.

    grif091 – I am all set. Installation of the 4204 module was pretty easy. I have the STAY and AWAY modes assigned to relays 1 and 2, and I still have two relays left for future use (would have to pull another 2 pairs of wire). Thanks again for your time and your knowledge.
