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

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

The best way to do this is remove the XR6 and put a fire rated zone expander
there in it's stead, using the 4 conductors from the house to the garage.
That will give 3 burg zones and one for the smokes. Then program the garage
keypad and zone expander as partition 2...bada bing..done and supervised.

| You can do this, but I'd suggest that you make darn sure that it's
| acceptable by your AHJ. Fer sure ....It's not acceptable to do this in
| my area and you're sure taking a chance of something going seriously
| wrong ...... especially where the fire detection is concerned.
|
| Keep in mind that I'm not familiar with either of the panels you're
| using but this is how I'd guess you should be able to do it.
|
| Program the XR200 to require end of line resistors on zones 7 and 8.
| Install the resistors across the zone terminals. Program (lets say)
| zone 8 for fire and zone 7 for burglary. Run three wires from the XRS 6
| panel to the XR200.
|
| Connect one wire from a negative circuit (ground) terminal in the XRS6
| panel to a negative circuit (ground) terminal in the XR200  ( A
| "common" ground connection must exist between the panels ....... I
| don't mean "earth ground")
|
| Connect the second wire from "output 4" of the XRS6 to the positive
| terminal of zone 7 of the XR200, along with one end of the existing end
| of line resistor. ( when output 4 of the XRS6 goes negative, it will
| trip the zone.)
|
| Connect the third wire from "output 3" of the XRS6 to the coil of a
| sensitive relay  ( low current draw ie a few mills ... see Altronix)
| installed in the XR200        The other side of the relay coil should
| be connected to the aux positive output of the panel through a diode.
| The normally open contacts of the relay are connected across the end of
| line resistor on zone 7. ( when output 3 goes negative, the relay
| contacts will short out the resistor simulating a fire alarm.)
|
| I'm not sure of the negative "swing" of these panels or the current
| available, so it's possible that this wont work over the distance of
| wire that you're using. If you can, just to be on the safe side, you
| should run a couple of "4 wires" and double up on the wires for each of
| the three wire runs or run 18 guage wire. If it still doesn't work
| because of lack of current or "swing" to negative, you might try
| biasing outputs 3 and 4  of the SRX6, positive, through a 2.2K
| resistor.
|
| But ........ see what happens first.
|
| Keep in mind this is not a good thing to do. There's no supervision or,
| as a matter of fact, nothing about this, that sounds like it should be
| done.
