First Alert VISTAHTKVR-V VISTA H Hybrid V-Plex Module

The First Alert VISTAHTKVR-V is an iBus-to-V-Plex gateway module designed to connect existing Resideo V-Plex devices to compatible VISTA H3 hybrid security control panels. Supporting up to 96 V-Plex devices, 172 input zones, and 52 relay modules, it enables integration of addressable intrusion sensors through two-wire power and data connections. The module features 12 VDC operation, supervised communication, dual tamper protection, and auxiliary power terminals. Up to four modules can be installed on a compatible VISTA H3 system, with one module assigned to each partition.

First Alert VISTAHTKVR-V V-Plex Gateway Module for VISTA H3 Hybrid Security Panels

The First Alert VISTAHTKVR-V is a V-Plex gateway module designed to integrate compatible addressable security devices with Resideo VISTA H3 hybrid intrusion control panels. The module converts communication between the panel's iBus interface and V-Plex two-wire devices, allowing installers to retain supported sensors and expansion hardware during security system upgrades. Manufacturer specifications identify support for up to 96 V-Plex devices, 172 input zones, and 52 compatible 4101SN relay modules, subject to the control panel's system capacity. A VISTA H3 panel supports up to four VISTAHTKVR-V modules, with one assigned to each partition.

The VISTAHTKVR-V supports compatible V-Plex motion detectors, glassbreak sensors, door contacts, smoke detectors, and addressable expansion modules. Supported devices include the 4191SN recessed contact, 4939SN surface contact, 4208SN eight-zone expander, 5193SD smoke detector, FG1625SN glassbreak detector, and 4101SN relay module. V-Plex communication transmits power and device data through a two-wire circuit, reducing the need for separate signal and power wiring on supported devices. The gateway operates in serial addressing mode only, requiring compatible dual-mode V-Plex devices to be configured for serial operation. Device supervision allows supported alarm, trouble, and status conditions to be reported through the connected security control panel.

The module operates on 12 VDC nominal power, with an allowable input range of 10-14 VDC and a base current draw of 56 mA, excluding connected V-Plex devices and auxiliary loads. It receives operating power through the VISTA H3 iBus connection and provides regulated auxiliary power terminals for compatible V-Plex devices requiring separate power connections. Auxiliary output capacity is limited by the connected control panel or power supply, with a manufacturer-listed maximum of 1.3A. The module includes front-cover and wall-removal tamper switches and supervised iBus communication to identify wiring interruptions. An onboard multicolor LED indicates normal operation, firmware updates, communication loss, and system trouble conditions.

The VISTAHTKVR-V gateway features a remote-mount enclosure measuring 6.93 inches wide x 5.43 inches high x 1.99 inches deep (176 x 138 x 50.5 mm). The included enclosure supports direct wall mounting or installation over a compatible electrical gang box. Its operating temperature range is 32 F to 122 F (0 C to 50 C), with relative humidity from 0% to 95%. Installers connect the module to the VISTA H3 iBus terminals, enroll it through control panel programming, and assign supported V-Plex devices to available zones or relays. Total iBus wiring length is limited to 3,000 feet using unshielded quad cable or 1,500 feet using shielded cable, with shorter runs required according to conductor size and connected current. Designed for VISTA H3 system upgrades and expansions, the VISTAHTKVR-V provides a supervised interface for integrating compatible legacy V-Plex equipment without replacing every installed sensor.
