Ademco 4219 expansion

I currently have a 20p. All my 8 wired zones are filled and I have about 9 wireless ones zone 9-18. I am thinking about adding wired alarms by buying the 4219 expansion board. My question is how is this programmed as far as zones, since 9-18 are wireless now. Do I have to change all my zones for each wireless contacts and use 9-18 as the expansion board? I am hoping not.

Nope, they anticipated such a scenario. The dip switch address settings allow you to start the expander at zone 9; zone 17; zone 25, zone 33, or zone 41.

I was about to write a similar question about 4229. I'm going to install one since my first 8 wired zones are full and I need to add more wired zones. I have none wireless (yet).

On my Vista 21IP manual says that the first 4219/4229 should be on address 07 (zones 09-16); I thought this was mandatory.

So doesn't matter what address between 7-11 I use for the first expansion module ?

Another question I have is that I read that I need to use 1k resistors instead of 2k resistors at each EOL on the expansion module? Why is this change on resistors ?

Regards

Nope, those are just the zone numbers that those given addresses start the expander on.

On the flip side, you can start the hardwire expander at zone 9 and then later add wireless on higher zone numbers.

The resistor change is because they haven't changed the design of the zone expanders since they were first introduced ~20 years ago, when 1k resistors were the standard on vista panels.

Hello, a little of learning,

About wiring on the 4229 zone expander of Ademco, each Zone has a response time of 300-500 msec, but Zone A could be set to response time of 10-15 msec.
What would I connect that a fast response time of 10-15 msec. could be needed ?

Regards

That higher response is for things like vault vibrations sensors, and other high security applications. For a typical residential install, the default setting is more than fine...
