Honeywell Home 4219 Wired 8-Zone Expander Module for VISTA-15P, VISTA-20P and VISTA-21iP

When you need to expand hardwired coverage fast, the Honeywell Home 4219 wired 8-zone expander module delivers a simple, reliable solution for VISTA security systems. This zone expander module adds up to 8 EOLR-supervised zones so installers can extend monitoring and intrusion protection without replacing the existing control panel. Designed for compatibility with VISTA-15P, VISTA-20P and VISTA-21iP panels, the 4219 connects via the control's console wiring for a low-labor installation and supports centralized alarm monitoring and surveillance integration. With a compact white housing that fits inside a universal cabinet and a low 35 mA current draw, it’s well-suited for retrofit jobs and new installations where space and power are constrained. Remote mounting includes tamper protection so any disconnection attempts are reported to the panel, helping maintain system integrity. For security integrators and facility managers looking to cost-effectively scale hardwired zones and improve monitoring coverage, the Honeywell Home 4219 is a dependable choice. Add it to your VISTA installation to expand protection and streamline surveillance setup.
