The 2W-B (2 wire) does not show up on the compatibility list for the
Vista 20.  You'll have to use the 4W and an EOL supervision relay.  Only
the following 2-wire smokes are compatible (see page 18 of your Vista 20
installation manual):

System Sensor 2300TB, 2400, 2400TH, 2451 w/ B401B Base, 2451TH w/ B401B
Base, 1400, 1451 w B401B Base, 2451 w/ DH400 Base, 1451 w/ DH400 Base,
1100 and 2100T

Use only UL approved compatible devices for connection to a listed
panel.  And the pro's here should really check their facts before
opening their big yaps!  :-)
