Vista-20P Max # of Zone Expanders

[DropIt]

Is there a maximum number of wireless zone expanders that you can add to a Vista-20P control panel?

Example, I could get a 5881ENH which would add 40 wireless zones, or is it possible to install two seperate 5881ENM expanders and place them in different places to get the best reception (say one for basement and one for second floor of my house) for a total of 32 wireless zones.

Will the two 5881ENM's cohabitat nicely?

Thanks,

I should also ask the following question:

From what I've read the Ademco 5881's all have an indoor range of about 200 feet. Is this suitable for reception for a 3000 square foot 2 story (and a basement) single family home?

Where's the best place to install the wireless expander in a case like this, I'd like to install it in the center of the basement.

The 20P will support a single RF reciever, no more, since the system works as a fixed addressable type.

The best location for a RF reciever is dependent on construction and range. I have yet to really see many issues with a 'standard' install by mounting the RF reciever near the control. The best location would be highest as possible, and in conditioned space (2nd floor closet) and nearest the center of the house. Barring that, a first floor closet will work as well. I haven't had any issues with a standard house before, only when in larger installs, or trying to push the distance between a house and outbuilding.
