How do I address a 4219 Zone Expander to a VISTA?
The Vista-15P and Vista-20P series control panels support hard wired expansion through use of the 4219, 8 zone hardwired expander. When adding a 4219 to one of these panels, the address for the expansion board, is determined by the zone numbers being added via that expander. For example, to add zones 9 - 16 on either the Vista-15P or Vista-20P, the address for the 4219 should be set to 7. This means dip switches 2, 3, and 4 should be off, and dip switch 5 should be on (in 4219's with 8 dip switches, #6 will always be ON for these panels). Dip switch 1 has nothing to do with the address, and is used to set whether the first zone on the expander, zone 9 in our example, uses a high speed response (10ms, dip switch 1 OFF) or a normal response (300ms dip switch 1 ON). The settings for these 5 dip switches are the same regardless if you have an old 4219, or one of the newer ones (which have 8 dip switches rather than 5). Here's a chart that will help determine addresses and dip settings:
|9 - 16||07||
(1 On =Normal, Off = Fast) 2 - Off, 3 - Off, 4 - Off, 5 - On
|17 - 24||08||(1 On =Normal, Off = Fast) 2 - On, 3 - On, 4 On, 5 - Off|
|25 - 32*||09||(1 On =Normal, Off = Fast) 2 - Off, 3 and 4 - On, 5 - Off|
|33 - 40*||10||(1 On =Normal, Off = Fast) 2 - On, 3 - Off, 4 - On, 5 - Off|
|41 - 48*||11||(1 On =Normal, Off = Fast) 2 - Off, 3 - Off, 4 - On, 5 - Off|
* These zones supported on the Vista-20P only.
As noted above, dip switch 6, in 4219's that have it, will always be ON for the Vista-15P and Vista-20P. Dip switches 7 and 8 are used to determine if these zones will use an End of Line Resistor (EOLR) or be Normally Closed, and whether or not the tamper is enabled or disabled (older 4219's with only 5 dip switches have a jumper that determines whether or not tamper is enabled. If the jumper is on the two pins closest to the center of the board, tamper is disabled, if it is on the two pins closest to the edge of the board, tamper is enabled. These devices also use a 1K resistor instead of a 2K resistor for End of Line supervision).
|7||On = Normally Closed zones only, Off = 2K End of Line Resistor in use|
|8||On = Tamper Disabled, Off = Tamper Enabled (Yes, I know that seems backward)|
Please Note: There was a brief period of time where 4219's were released that did not support the use of dip switch 7 (meaning they ALWAYS used the EOLR) and dip switch 7 should have always been in the ON position, but they were released with documentation stating that dip switch 7 was in use. On these units, if you turn off dip 7 with the EOLR's in place (as the instructions indicate you should), the zones will always be faulted, so if you seem to have everything set correctly, and the resistors are in place, but your zones continue to show faults, try turning dip switch 7 ON. When changing dip switch settings, I recommend powering down, making the change, then powering back up.
