Kidde KN-COB-IC Hardwired CO Detector with 9V Backup & 3 LEDs

Overview

The Kidde KN-COB-IC hardwired carbon monoxide detector is designed to help households stay aware of CO levels with dependable sensing and clear indicators. It operates on a standard 120V power supply and includes a 9‑volt alkaline battery backup tucked in the back, so monitoring can continue even during a power outage. The device uses an electrochemical sensor to detect carbon monoxide and delivers an audible alert when gas is detected.

Why this detector stands out

In homes, CO is a colorless, odorless gas that can pose a risk when concentrations rise. This model emphasizes reliable operation, straightforward indicators, and networked alerts, offering peace of mind without complexity. A 85‑decibel alarm is designed to wake occupants, while LED indicators keep you informed at a glance.

• 85‑dB alarm helps ensure alerts are heard, even from other rooms.
• Red LED flashes during a CO event; green LED confirms power is present.
• Interconnect capability supports up to 24 Kidde devices on a single wiring network.
• Smart interconnection patterns distinguish CO alerts when linked to Kidde smoke alarms.
• UL 2034 compliant with a 10‑year limited warranty on the alarm portion.

Key features and practical use

Designed for everyday living, this detector blends into living spaces while providing quick at-a-glance status. The 9V backup ensures continued monitoring through minor outages, and the unit chirps at the end of its service life to indicate replacement is due. Regular replacement every 5 to 7 years helps you benefit from the latest sensing technology and safety standards.

• Power source: 120V AC, 60 Hz with a built‑in 9V backup (battery included).
• Interconnection: linkable with up to 24 other Kidde devices on one network.
• Alarm patterns can vary when interconnected with Kidde smoke alarms, aiding quick identification of alerts.
• Service life cues: the alarm chirps when its life is ending, indicating replacement is needed.

Installation tips and best practices

Place CO detectors on every level of the home and near sleeping areas to maximize early warning. Keep units away from cooking or heating appliances by about 15 feet to minimize false alarms. Always follow local codes and the manufacturer’s guidelines for mounting and maintenance.

Pairing with a compatible smoke detector on the same wiring network can create a coordinated home safety network. While the device provides important alerts, it does not guarantee results, so routine checks and timely replacements are recommended to maintain optimal performance.
