Zone Doubling Programming
Zone doubling requires 3.65 k Ω and 2.2 k Ω EOL resistors as shown in Table 13. If zone doubling is
not used, see On-board Location EOL Resistor Value on page 103, and DX2010 Configuration
Options on page 127, for on- and off-board zone EOL resistor configuration. For proper zone doubled
wiring, see the DS7200V2 Installer’s Guide (P/N: 4998153893).
To use both on-board and off-board zone doubling at the same time, use the following steps:
1. Double Locations 1 to 8 with Locations 9 to 16.
a. Set the Device Type for Locations 1 to 16 to 1 (on-board).
b. Set Address 1026 (On-board Location EOL Resistor Value) to 4 (Zone doubled, 2.2 k & 3.65 k
EOL resistors).
c. Use 3.65 k EOL resistors on Locations 1 to 8, and 2.2 k EOL resistors on Locations 9 to 16.
2. Double Locations 25 to 32 with Locations 33 to 40.
a. Set the Device Type for Locations 25 to 40 to 3 (DX2010 zone doubled).
b. Set the DX2010’s DIP switches to Address 107 (Locations 25 to 40). See Table 14.
c. Use 3.65 k EOL resistors on Locations 25 to 32, and 2.2 k EOL resistors on Locations 33 to 40.
Locations 17 to 24 cannot be used for zone doubling when doubling on-board and off-board zones at
the same time. These locations can still be used as RF zones, or as non-doubled zones.
