Ademco/Honeywell Security 4219

Honeywell 4219 Wired Zone Expansion Module The Honeywell 4219 is a wired zone expansion module designed to provide up to eight additional hardwired zones of protection for Honeywell VISTA-15P, VISTA-20P, or VISTA-21iP alarm control panels. It serves as an ideal solution for expanding existing security systems when additional hardwired alarm devices are required, but no more available zones are present. Key Features: Expansion Capability: Adds up to eight additional hardwired zones of protection to compatible Honeywell VISTA alarm control panels. Wiring Flexibility: Supports end-of-line resistors (EOLR) supervision or Normally Closed (NC) wiring for each zone, with configurable Dip Switches for selecting the wiring options. Included Resistors: Includes 1K or 2K ohm resistors required for each EOLR zone, simplifying installation and setup. Zone Termination: Each programmed zone may need to be terminated with a resistor, depending on the Dip Switch setting, eliminating the need for r
