If you have 6 window sensors and each have their own home run, can they be connected to one port on

If you have 6 window sensors and each have their own home run, (and you dont need to know which one is open individually), can they be connected to one port on the ELK, or will it take up 6 of the 16 ports?

Thanks

If your sensors are normally closed then yes you can combine them into one zone.

1) Connect Elk Zone Input to sensor 1 wire 1
2) Tie sensor 1 wire 2 and sensor 2 wire 1 together
3) Tie sensor 2 wire 2 and sensor 3 wire 1 together
....
X) Tie last sensor wire 2 to Elk Zone Common

Voila! The total length of the circuit might need to be considered, unfortunately I can't answer that for you.

Connect them in series and the connect the bitter ends to a single zone.

You'll be making a giant loop.
If you have six cables with red/black wires inside, then you would connect the red of the first cable to one side of the zone then the black in the same cable to a red in the next cable.
Continue connecting black to red in the next cable until you connect the last red, you should have a free black wire left.
Conenct this to the other side of the zone.

If you need EOL resistors, connect ONE in series on one side of the zone, I usually use the red side for consistency.

If you have eol resistors hidden in the walls somewhere around each window, then no (or at least not easily).

If each contact is a home run without eol resistors, then yes, as described above.

Put an ohm meter on each pair of wires, if the resistance is zero (or near zero), then you should be fine. If it comes back 1000 ohms or more, then eol resistors are out there somehwhere and you can't run your windows in series together or the resistance will be waaaaaay to high. The only way to fix that would be to find the eol resistors and remove them.
