The 4219 is a wired zone expander that allows you to add 8 wired zones. This allows you to add more hardwire zones to your system without having to change out your panel for one that will handle more zones. You can add multiple 4219 to a system to save you money and give you more protective ability when it comes to your Ademco series panel.
