How Many Wireless Zones Can I Program On A VISTA 20P?

The total number of wireless zones that can be programmed on a Vista 20P control panel is 56.

The Honeywell Vista 20P control panel can support up to 40 wireless expansion zones and also supports up to 16 wireless keyfobs which can be programmed without using any of the 40 wireless expansion zones, (the Vista 20P control panel does need to be the latest version).

The Vista 20P control panel has 8 on board hardwired zones (which is standard, 15 when zone doubling feature is being used) and supports up to 40 hardwired expansion zones.

To utilize wireless devices the Vista 20P control panel must be paired with either an RF keypad or wireless receiver. Both the Honeywell 6150RF and 6160RF keypads are a great option. The 6150RF is a fixed English keypad that has a 5881ENM 16-zone wireless receiver and a 5800TM transceiver built into the keypad. The 6160RF is an alphanumeric alarm keypad that has a 5881ENH wireless receiver and a 5800TM transceiver built in that will support as many wireless zones the control panel will support, in this case 56. The compatible wireless receivers are the Honeywell 5881ENL which supports 8 wireless zones. The 5881ENM supports up to 16 wireless zones and the Honeywell 5881ENH which supports unlimited.

The Vista 20P supports only one wireless receiver. So if a 5881 series wireless receiver and an RF keypad are connected to the same control panel, one of the wireless receivers would need to be disconnected. When deciding on which wireless receiver to use, think of the future. Is there is a possibility of adding more wireless devices, a higher wireless receiver might be the better choice or a 2nd keypad also might be needed and be the correct solution.
