GLBSUNION 2-Pack Combination Smoke & CO Detector Alarm – Battery Operated UL 217/2034

All-in-one safety for home, travel, and work

The GLBSUNION 2-pack merges smoke detection and carbon monoxide warning into a single, compact unit. Powered by two AA batteries (not included), these alarms keep watching for smoke and CO even when power is out, making them ideal for basements, bedrooms, offices, cars, and travel use.

Two sensors work independently for fast, reliable alerts. A photoelectric smoke sensor targets common slow-burning fires, while an electrochemical CO sensor detects rising carbon monoxide levels. This 2-in-1 design delivers critical warnings from both threats in one compact device, helping you stay aware without juggling multiple detectors.

On the face of the unit, indicator lights clearly signal the presence of smoke or CO, while an 85 dB siren delivers a loud, unmistakable alert. The combination of visual cues and a strong siren helps you respond quickly, whether you’re at home, in a sleeping area, or away in a travel setting.

Easy to test, easy to silence, easy to install

• The Test/Silence button lets you verify operation weekly and silence the alarm when needed.
• Low battery warnings help you know when to replace batteries so the system remains active.
• No rewiring required for installation; mount on a wall or ceiling using the included mounting bracket, screws, and anchors.

What you get in the box is straightforward and practical: two detector alarms with mounting brackets, one manual, and four screws. The unit is certified to UL safety standards (UL 217/2034), offering a standard of quality you can rely on for everyday safety.

Real-world versatility

• Basements and other low-ventilation spaces benefit from continuous, independent monitoring for smoke and CO.
• Portable, battery-powered operation makes it a handy safety companion for travel, hotels, and rental spaces.
• Compact design fits easily in living rooms, bedrooms, home offices, and hallways without crowding the room.

Note: This is a safety device designed to alert you to detected smoke and CO. It is not a medical device, and results may vary by environment and usage. UL compliance indicates adherence to important safety standards.
