Soewolit 4-Pack Battery-Operated Smoke & CO Detector | 2-in-1 Alarm with Digital Display

Meet the Soewolit 4-pack, a versatile 2-in-1 smoke and carbon monoxide detector set designed for easy home safety. Each unit combines a photoelectric sensor for smoke with an electrochemical CO sensor, delivering a compact alarm that helps you monitor two critical risks in one device. The digital display provides real-time readings while the standby mode keeps the screen off to minimize distraction when conditions are stable.

Clear, real-time readings you can act on

• Digital display shows current smoke and CO levels at a glance.
• Standby mode blanks the display but preserves ongoing detection.

Installation is simple with battery operation, so you can place them where you need coverage without wiring. After inserting batteries, the alarms power on quickly and begin monitoring, signaling with a high-pitched alert if action is needed.

• Low battery warning with a flashing red LED and an audible alert louder than 85 dB.
• Green power LED blinks about every 60 seconds during standby, signaling healthy operation.
• Red Alarm LED indicates an active fire or CO alert; Yellow Fault LED flags malfunctions.

Designed for flexible placement in common living spaces, these detectors can be mounted on walls or ceilings using the included bracket, screws, and anchors. Use them in living rooms, kitchens, bedrooms, basements, or hallways to extend coverage where it matters most.

What you get and how it helps: four detectors, mounting brackets, screws, and anchor plugs for quick setup; clear instructions for testing and maintenance; reliable, battery-powered operation that continues during power outages.

• Four detectors, mounting brackets, screws, and anchors.
