Honeywell Home Intrusion 4208SN 8-zone Interface

Product Description

The HONEYWELL HOME INTRUSION 4208SN is a V-Plex 8-zone interface module designed to expand zone capacity on compatible intrusion detection control panels. It connects to the V-Plex polling loop, allowing up to eight additional hardwired zones to be supervised without running separate wiring back to the main panel. The module is sold as a single unit and is installed by licensed security system technicians during new construction or system expansion work. It fits into standard enclosures and integrates directly with the V-Plex protocol for reliable zone supervision and tamper detection.

The 4208SN is used in residential and light commercial intrusion detection applications where additional hardwired zones are needed beyond the control panel's native capacity. It is well suited for retrofit installations where existing wiring infrastructure is already in place and the installer needs to add door, window, or motion detector zones without replacing the host panel. The module supports V-Plex loop architecture, keeping wiring runs clean and reducing installation labor on multi-zone projects.

Key Features

• Supports up to 8 hardwired zones via V-Plex polling loop connection
• Expands zone capacity without replacing the host control panel
• Compatible with V-Plex loop architecture for simplified wiring
• Single-unit packaging suitable for individual zone expansion jobs
• Designed for use in residential and light commercial intrusion systems

Compatibility

Designed as an OEM-style expansion module for intrusion detection control panels that support the V-Plex polling loop protocol. Refer to the host panel documentation to confirm V-Plex loop compatibility before installation.

Installation Notes

Installation should be performed by a licensed security or low-voltage technician in accordance with local codes and the control panel manufacturer's wiring guidelines. Power down the host control panel and disconnect the backup battery before wiring the module to the V-Plex polling loop. Verify zone end-of-line resistor values match the host panel's requirements before commissioning. Follow all applicable NEC low-voltage wiring requirements for the jurisdiction.
