Question 1

Does this system support the envisalink evl-4?

Accepted Answer

Yes, it installs as a keypad (power from cabinet and a couple of data lines).  You will have to devise your own mounting or (measure and) drill an odd hole pattern.  I mounted the EVL-4 to a small piece of plastic with the included standoffs, then attached the plastic to the back of the cabinet with a couple of screws.  I replace my old vista 15 with the vista 20p, used zone doubling, added a wireless receiver/alpha keypad, and added the evl-4 all at once.  In retrospect, I would get the panel working and programmed prior to adding the envisalink.  Once I'm through testing, my next step is to add their monitoring service.

Question 2

Is the Vista 20-P RF capable out of the box? Can I add wireless motion detectors or do I need 2 buy additional wireless module first?

Accepted Answer

You have quite a few options: Install a 6160RF Keypad (alpha which is zone description read out), 6150RF (no zone description but has RF) You must be aware that a 6150RF has a medium receiver and a 6160RF has a high receiver and this means the 6150RF will allow 16 zones whereas the 6160RF will allow the max number of zones your panel can support. If you install a 6150RF and you try to place 17 wireless zones you will get an error. You can also do standalone receivers such as the 5881ENL (low range adds 8 wireless zones), 5881ENM (16 zones), 5881ENH (high range based on your panels max wireless zones) all of which can be used on a V15P, V20P, V32FB, V128BPT etc.. There is a 5881ENHC which is used in commercial applications. I own an alarm company and we buy our panels here because they are cheaper than our distributor.

Question 3

What battery do I need to use (voltage, amp hours...)?

Accepted Answer

The Vista20P uses a rechargeable 12 volt dc 4 amp hour battery.The 12vdc 5 amp hour or 12vdc 7 amp hour batteries can also be used.The larger amp hour rated batteries last longer during a power outage.Hope this helps.

Question 4

Does this come with a power supply and/or battery or do I have to buy those seperately

Accepted Answer

The power supply is right on the same circuit board as the alarm board.  See the large heat sink?  That is the power supply my friend.  Power transformer to power it but no backup battery as size of battery is the installer's choice.
