Ademco Inc. 1046870 Smoke Co Alarm 120V Hardwire

Product Description

The ADEMCO INC. 1046870 is a combination smoke and carbon monoxide alarm designed for hardwire installation at 120 volts AC/DC with integrated battery backup. It provides dual-threat detection in a single unit, monitoring both smoke and CO levels and triggering audible alerts when hazardous conditions are detected. The alarm supports interconnect wiring, meaning when one unit triggers, all interconnected alarms in the building sound simultaneously. Licensed electricians and HVAC technicians install this device as part of residential or light commercial life-safety systems. Its combination detection capability and hardwire design make it a standard choice for new construction and code-driven retrofit projects.

This alarm is suited for residential and light commercial applications where local codes require hardwired smoke and CO detection with battery backup. It is sold as a single unit and is appropriate for installation in bedrooms, hallways, and common areas. The interconnect feature supports whole-building alarm networks, making it well-suited for multi-room and multi-story installations where simultaneous alerting is required by code.

Key Features

• Dual-function detection monitors both smoke and carbon monoxide in one unit
• 120V AC/DC hardwire connection with battery backup for continued operation during power outages
• Interconnect capability allows all linked alarms to sound when one unit is triggered
• Single-pack unit suitable for individual room or whole-building networked installations

Compatibility

Designed as an OEM-style hardwire replacement or new-installation combination smoke and CO alarm compatible with standard 120V interconnected alarm wiring systems.
