Lifesafety Power AH2-BOXED AC Helix Redundant AC Power Module

Overview

The AH2-BOXED is a redundant AC power expansion module that integrates into the Lifesafety Power Helix family. Its primary function is to add failover capability to AC-powered security infrastructure by providing dual independent AC inputs—eliminating a single point of failure on AC mains. In larger surveillance, access control, or integrated security deployments, loss of main AC power can cascade across multiple devices; redundant AC inputs ensure continued operation if one circuit or utility service fails.

Compatibility & Integration

This module is designed to pair with Lifesafety Power Helix series controllers and power distribution units that accept AC expansion modules. The AH2-BOXED accepts AC input across 110–230V—accommodating both standard North American (120V) and international (230V) utility feeds. Check your existing Helix system documentation for module slot availability and wiring requirements before ordering.

Deployment Context

Redundant AC modules address a specific risk: single-input systems that lose power mid-event. Common deployments include warehouse automation environments with critical NVR recording and access control systems, multi-tenant office security, and retail chains where power loss across even one location damages incident evidence. When paired with a UPS or dual utility feeds, redundant AC architecture maximizes availability for 24/7 surveillance.
