First Alert VISTAHRELAY VISTA H Relay Module

The VISTAHRELAY module expands your VISTA H series control panel with up to four hardwired relay outputs, each supporting form-C (SPDT) switching. Remote mounting connects via iBus wiring to the panel's power supply, with battery backup during AC loss.

Built-in tamper detection alerts you if the front cover is removed, while supervision monitoring detects cut wiring and reports potential operational issues. Choose surface wall or gang box mounting to fit your installation needs. Removable terminal strips simplify wiring access for faster setup.

Supports multiple relay configurations including normally open, normally closed, common, double balanced, zone doubling, and end-of-line resistor types. Rated for 3A at 30VDC or 2A at 120/240VAC with resistive loads. Compact dimensions (6.93" W × 5.43" H × 1.99" D) fit tight spaces. Operates reliably from 32–122°F in humidity up to 95% RH with 400ms loop response time.
