Honeywell Home Intrusion 4190SN 2-zone Expander Eol

Product Description

The Honeywell Home Intrusion 4190SN is a V-Plex 2-zone expander module with end-of-line (EOL) resistor functionality, designed for use in hardwired security and intrusion detection systems. It extends the zone capacity of compatible control panels by adding two additional supervised zones over a single twisted-pair V-Plex polling loop. Licensed security technicians and alarm system installers typically deploy this module when a panel's native zone count needs to be expanded without running additional dedicated wiring back to the main board.

The 4190SN is suited for residential and light commercial intrusion detection installations where V-Plex loop architecture is already in place. It connects directly onto the existing polling loop and presents each zone to the panel as a standard supervised input. This makes it applicable in retrofit scenarios and new installations alike, wherever the control panel supports the V-Plex protocol and additional zone inputs are required.

Key Features

• Adds 2 supervised zones to a compatible V-Plex control panel over a single twisted-pair loop
• Integrated end-of-line resistor functionality for zone supervision without external resistors
• Designed for V-Plex polling loop architecture, minimizing additional field wiring
• Suitable for both new installations and retrofit zone-expansion projects
• Single-unit quantity per package for straightforward inventory and job-site management

Compatibility

Designed as an OEM-style expansion accessory for security control panels that support the V-Plex polling loop protocol. Refer to the panel manufacturer documentation to confirm compatibility before installation.

Installation Notes

Installation should be performed by a licensed security or alarm system technician in accordance with applicable local and national codes. Power down the control panel and disarm the system fully before connecting or disconnecting any V-Plex loop devices. Follow the control panel manufacturer wiring guidelines for loop polarity and maximum device count per loop. Do not exceed the polling loop capacity specified by the panel manufacturer.
