First Alert Hardwire Combination Smoke and Carbon Monoxide Alarm | SMICO100-AC, 9V Battery Backup

First Alert Hardwire Combination Smoke and Carbon Monoxide Alarm – SMICO100-AC

The SMICO100-AC is a hardwire combination alarm manufactured by First Alert. It monitors both smoke and carbon monoxide levels, providing dual protection in a single device.

Hardwire Design

Designed to be connected directly to a building’s electrical wiring, the unit eliminates the need for batteries under normal operation while maintaining a reliable power source through the building’s mains supply.

9 V Battery Backup

A 9 V battery backup is included to keep the alarm functional during power interruptions. When the main power is lost, the battery automatically takes over, ensuring continuous monitoring of smoke and carbon monoxide.

Installation and Compatibility

As a hardwire model, it is intended for use in homes or buildings with existing electrical infrastructure. The alarm is compatible with standard 120‑volt household wiring systems.

Operational Features

When the alarm detects hazardous levels of smoke or carbon monoxide, it emits a loud audible alarm to alert occupants. Once the hazardous condition clears, the alarm returns to a standby mode until another event is detected.

Maintenance and Safety

Routine checks of the alarm’s function and battery status are recommended to ensure ongoing effectiveness. The device is designed to provide reliable performance when connected to a proper electrical system.
