Honeywell Vista 20P PROM
Upgrade chip for the VISTA 20P
If you need to upgrade your VISTA 20P so that it can be made to work with Total Connect, the 20P PROM is what you're looking for.
If you need to upgrade your VISTA 20P so that it can be made to work with Total Connect 2.0, the 20P PROM is what you're looking for. You can determine whether your system needs the upgrade by looking at the already-installed PROM chip located in the center of the board. It should read out "WA20P-" followed by the revision number. For example, "WA20P-9.12" for a rev. 9.12 system. It must be 9.12 or higher. If your panel does not have a 9.12 or higher revision, you will need to replace the chip and get a Total Connect 2.0 compatible radio. Keep in mind that your 20P will need to be revision 2.0 or higher in order to be PROM chip upgradeable. If your panel does not meet this spec you will have to swap in a new system.
You can purchase the Honeywell AlarmNet communicator and PROM chip separately or you can get a TC2 kit with Alarm Grid. The most popular kits are the iGSMV4G-TC2 and the CDMA-X-TC2 kits. The iGSMV4G is a dual path communicator that support internet and/or AT&T cellular communications. The CDMA-X is a Verizon cellular communicator. Both kits come with a PROM chip upgrade of the newest revision available at the time. If you are interested in standalone internet monitoring you can still purchase the iGSMV4G-TC2 kit. Just remember to inform your monitoring company to disable the cellular path to avoid any additional fees.
