Here are some install hints: Old versions of this came with 1k EOL resistors. This newer device came with and uses 2k EOL end of line resistors. The green onboard LED is not lit when it is working properly with the panel on my system. I don't know what the green LED means. Set address to 07 and the 8 new zones start at zone 9 I think Set address to 08 and the 8 new zones will start at I used this because of zone doubling Set address to 09 and the 8 new zones will start at On mine, I started with zone 17 since the device address is 08 and change the input type from 3 RF to 2 AW for auxiliary wired zone.

I repeated this for the 8 zones of the device. The last zone zone 8 on the device corresponds to zone 24 on my system. Watch out for power problems during testing- My expander has its own power supply AD so to de-energize the whole system, I'm dealing with 2 power supplies and 2 batteries. I disconnected the bus power and ground between the vista 20p and the to make it easier to turn pieces on and off. Not sharing the common bus ground between the vista 20p, the , and the RF keypad daisy chained off the didn't seem to work.

Here is what wound up working for me there is probably a better way to do it. NOTE - the whole system seems to work better when I turn the pieces on in this order: 1. Energize Energize RF keypad. Does not fit the Vista 20P box.

It has to be mounted externally - with lesser security. Or you have to drill holes and find special screws with insulator pads to make it fit.

And look at the cheap directions - they are printed on the inside of the shipping box. Seriously, how about a piece of paper here? Received unit today. Please note that this is an Ademco not a Honeywell Even know they are essentially the same, there is a newer Honeywell branded model available. The one I received was in a very old box as pictured and the associated literature is dated I'm assuming 15 years of storage affects it negatively in some way.

That being said I subtract only subtracted 1 star because the picture is correct but the model is not as stated. It's a zone expander, not much to get excited about.

Works as it should, quality part. Just buy it, no worries. Check your programming via the Compass software or thru the KP and its all good. Don't forget to set the address switches. Go to Amazon. Back to top. Get to Know Us.
