To program a 4219, you must first set its address using the DIP switches on the module itself, then connect it to the control panel’s ECP bus, and finally, enter the panel’s installer programming to assign the zones. The specific DIP switch settings and panel programming steps will vary based on your control panel model and the desired zone numbers, so always consult the module’s and panel’s instruction manuals.
Wire the module to the control panel
- Connect to ECP bus: Wire the 4-terminal block (TB2) on the 4219 to the ECP terminals on your Vista control panel’s keypad bus.
- Connect zone wires: Connect the hardwired sensors to the 12-position terminal block (TB1) on the 4219.
- Install resistors: If using end-of-line resistors (EOLR), connect a 2K-ohm resistor across the end of each zone loop.
Program the zones on the control panel
- Enter installer programming: From the keypad, enter [Installer Code] + 8 + 00. The default installer code is 4112.
- Go to zone programming: Press *56.
- Program each zone: Follow the prompts to select each zone you want to program. The first zone on the 4219 will correspond to its assigned address (e.g., zone 9 for address 7).
- Set zone type: For zones connected to the 4219, set the zone type to “Aux Wire” or equivalent, not RF transmitter.
- Exit zone programming: 00
- Exit programming. Press *99
DIP switch number 6 should be set to the ON (up) position for most VISTA alarm systems, including the 15P, 20P, and 21iP. This switch is part of the group that sets the module’s address, and for these specific panels, it is a required part of that setting.
DIP switch number one is for selecting the response time for Zone A. Setting it to OFF provides a fast 10ms response time, while setting it to ON provides a normal 300ms response time. The normal setting is often the default, as shipped from the factory.
DIP switch 7 on a Honeywell 4219 zone expander determines the type of zone wiring. Set to ON for Normally Closed (NC) zones without an end-of-line resistor, and to OFF for End-of-Line Resistor (EOLR) operation, which is often required for UL installations.
Dip switch #8 determines the status of the case tamper. With dip switch #8 in the OFF position, the case tamper is enabled, and if the cover is removed, it will trigger a tamper signal. With the dip switch #8 in the ON dip switch #8 determines the status of the case tamper. With dip switch #8 in the OFF position, the case tamper is enabled, and if the cover is removed, it will trigger a tamper signal. With the dip switch #8 in the ON position, the case tamper is disabled.
