The HONEYWELL HOME INTRUSION 4193SN is a V-Plex 2-zone expander module designed to add supervised zone capacity to compatible security control panels. It connects via the V-Plex polling loop, allowing technicians to expand a panel's zone count without running additional home-run wiring back to the main board. The module communicates over a single twisted pair, reducing installation labor in both new construction and retrofit applications. Security installers and alarm technicians use this module to scale zone capacity efficiently within V-Plex-compatible systems.
The 4193SN is suited for residential and light commercial intrusion detection systems where additional zone inputs are needed beyond the base panel capacity. It integrates into V-Plex polling loop architectures, making it appropriate for applications such as door and window contact expansion, motion detector zones, or other supervised device inputs. The module ships as a single unit and is categorized as a V-Plex expander and accessory component.
Designed for use with security control panels that support the V-Plex polling loop protocol. Refer to your panel documentation to confirm V-Plex loop compatibility before installation.
Installation should be performed by a licensed alarm or low-voltage technician in accordance with applicable local codes and manufacturer documentation. Power down the security panel and disconnect backup battery before connecting or disconnecting any loop wiring. Follow the panel's enrollment procedure to register the expander module on the V-Plex polling loop after physical wiring is complete. Consult the product data sheet for terminal assignments and loop wiring specifications.
