First Alert VISTAHRELAY VISTA H Relay Module

Add up to four hardwired relay outputs to your VISTA H series control panel with this versatile relay module. Designed for remote mounting on surface walls or gang boxes, it connects directly to the panel's iBus wiring terminals for seamless integration. Built-in tamper detection alerts you if the front cover is removed, while supervision monitoring detects cut wiring and triggers alarms if the module becomes inoperative. Removable terminal strips simplify installation and wiring access. Supports multiple relay configurations including normally open, normally closed, common, double balanced, zone doubling, and end-of-line resistor types. Operates on 12VDC nominal power with on-board regulation and battery backup if AC power is lost. Compact dimensions (6.93" W × 5.43" H × 1.99" D) fit tight spaces. Contact rating of 3A at 30VDC and rated for 120/240VAC loads. Fast 400ms loop response time with 2.2K ohm loop resistance requirement. Rated for temperatures from 32–122°F and humidity up to 95%.
