Battery Powered Combination Smoke & Carbon Monoxide Alarm – P4010DCSCO-W

The P4010DCSCO-W Battery Powered Combination Smoke and Carbon Monoxide Alarm is an advanced dual-protection safety device designed to detect both smoke (fire) and carbon monoxide (CO) in a single, integrated unit. It is built with a 10-year sealed lithium battery, ensuring long-term protection without the need for battery replacement or maintenance.

This model features wire-free interconnect capability, allowing multiple compatible alarms in a home to communicate so that when one alarm detects a hazard, all connected alarms sound simultaneously. This provides faster and more effective emergency awareness throughout the entire property.

A key highlight of this alarm is its voice notification system, which provides clear spoken alerts such as “Replace alarm” at end-of-life and “Hush mode activated” during temporary silencing. This improves clarity during emergencies and reduces confusion compared to standard beep-only alarms.

The unit also includes a three-color LED status ring, which clearly indicates whether the alarm is in standby, alarm, or error mode, allowing users to quickly understand its status at a glance.

To enhance usability and comfort, the alarm features ambient light sensing technology, which reduces nuisance chirping at night by adjusting based on day/night conditions. It also includes a bug screen to protect internal components from insect intrusion, improving long-term reliability.

When used with compatible systems, such as a Wi-Fi bridge, the P4010DCSCO-W can support smart home integration, enabling alerts for fire, weather events, and security notifications through connected devices.

Designed to meet modern safety standards, this alarm supports wire-free expansion of interconnected systems, making it ideal for both new and existing homes without the need for rewiring.
