Know before you buy
The Ademco 4219 is designed to increase the number of wired zones on compatible Ademco alarm control panels, allowing you to add more sensors or security points to an existing system.
Unlike wireless expanders, the 4219 requires a physical hardwired connection to your alarm panel. This provides a highly reliable, interference-free connection that is ideal for installations where you prefer not to rely on battery-powered sensors.
The unit is tested for operational integrity. While you may notice minor cosmetic wear like surface scratches, these do not impact the functionality or reliability of the zone expansion.
No, it is specifically designed for compatible Ademco alarm systems. You should verify that your specific control panel model supports the 4219 expander before making a purchase.
Because this is a used item, ensure that all necessary mounting hardware, wiring harnesses, or specific accessories you require are visible in the product images, as only what is pictured is included.
