Honeywell CDMA-X-TC2

The Honeywell CDMA-X-TC2 is a kit that bundles the CDMA-X Verizon cellular communicator with a PROM chip upgrade. Although the CDMA-X supports other Honeywell VISTA panels, this kit is designed specifically for the VISTA-15P and VISTA-20P. If you have an older VISTA-15P or 20P this kit offers an affordable way to upgrade your panel to the newest software and add cellular communications. Honeywell only supported AT&T radios until 2016 when they released a line of Verizon ready radios for their various product lines including the LYNX Touch, LYNX Plus, Lyric and CDMA-X for the VISTAs.

If your 15P or 20P has a software revision of 2.0 or higher than you can simply swap the prom out with the chip included with this kit. The number after the model number on the chip will show you the revision number. For example, if you have a VISTA20P Revision 5.0 it will say, "WA20P-5.0." These prom chip upgrades will also work for Safewatch Pro 2000 and 3000 panels. These are ADT branded 15P and 20P panels.
