This is true for a host of Honeywell devices, including zone expanders, wireless receivers, relay modules, touchscreen keypads, traditional keypads, internet communicators, and cellular communicators. Each device is given its own address which helps it communicate with the control panel.
Certain devices are automatically programmed with the proper addresses as soon as they are wired into the control panel. Others require manual programming. Below you'll find a list of devices and their corresponding device addresses.
05-06: Touchscreen Keypads; enable using *189 programming field; requires programming on keypad and control panel
07-11: 4219 and 4229 zone expander; dip switch settings affect which address is automatically enabled upon installation
16-23: Regular Honeywell Keypads (16 is default enabled); the others need to be manually programmed by enabling fields *191-196
25: Total Connect monitoring service; enable field *91
28: 5800TM Transmission Module (automatically assigned)
Correctly programming your devices ensures that they will work properly with your Vista 20P.
