TJTFJS 3-Pack 2-in-1 Smoke & CO Detector – 85 dB Alarm, LCD Display, Battery Powered

Comprehensive dual-sensor protection in a convenient 3-pack

Meet the TJTFJS 3-pack 2-in-1 smoke and carbon monoxide detector, designed for homes, offices, and hospitality spaces. Battery powered for flexible placement, this trio lets you outfit multiple rooms with reliable detection without wiring hassles. Expect a compact device that blends into living areas while keeping key areas safeguarded day and night.

Fast, accurate alerts with dual-sensor technology

The detector combines a photoelectric sensor for smoke detection with an electrochemical sensor for CO, aiming to deliver quick, precise alerts as conditions change. Realistic in-use scenarios—such as a kitchen flare-up or a CO buildup after a faulty appliance—can be monitored with this 2-in-1 approach, helping you stay informed without relying on a single sensing method.

• Dual-sensor detection (photoelectric + electrochemical) supports rapid, reliable alerts.
• Large LCD display shows real-time status, plus battery life at a glance.
• 3-color LED indicators provide at-a-glance status during daytime or night-time use.
• 85 dB alarm with LED flash offers audible and visual notification across rooms.

Designed for everyday use and easy installation

In daily life, a clearly visible screen and bright LEDs help you monitor conditions without confusion. The 85 dB alarm is designed to wake or alert occupants as needed, while the local test button supports simple maintenance routines. The battery-powered design means you can place units in bedrooms, living areas, hallways, or hotel rooms where hard wiring isn’t practical.

• Battery-powered, enabling flexible placement in multiple spaces.
• Simple setup that fits homes, small offices, and hospitality environments.
• Built-in test button for quick self-checks and ongoing confidence.
• LCD and LED indicators keep you informed day and night.

With three units in one pack, you can extend coverage to key zones—entryways, sleeping areas, and common spaces—without sacrificing clarity or ease of use. While it does not replace professional safety systems, this 2-in-1 detector can provide immediate, on-site awareness and a straightforward way to monitor potential hazards in real time.
