X-Sense XP0H-WN Wireless Smoke and CO Detector 3-Pack with 10-Year Battery

The X-Sense XP0H-WN is a three-pack of wireless combination smoke and carbon monoxide detectors, with a sealed 10-year lithium battery and alarms that sound together when interconnected.

• Smoke and carbon monoxide detection in one device — covers both hazards with each alarm.
• Wireless interconnection — interconnected alarms sound together when one detects smoke or CO.
• Sealed lithium battery powers each alarm for 10 years — no frequent battery replacements.
• 5.7-inch (145 mm) mounting bracket — covers a wider area, including old screw holes and ceiling marks.
• ETL Listed and meets UL 217 and UL 2034 safety standards — the detector meets standards for smoke and CO alarms.
• XP0H-WN does not have Wi-Fi and cannot be used with a base station — its connection feature is wireless interconnection.

Smoke and carbon monoxide alarms are intended to alert people to two different household hazards. The XP0H-WN combines both detection functions in one unit, while wireless interconnection lets linked alarms alert people throughout the home when one detects smoke or carbon monoxide. The three-pack is designed for households that want multiple alarms working as an interconnected set.

What does the XP0H-WN detect?

Each X-Sense XP0H-WN detects both smoke and carbon monoxide in a single alarm. This 2-in-1 design brings the two detection functions together instead of requiring a separate device for each hazard. It is intended for home smoke and CO alerting, with alarms sounding when either type of hazard is detected.

• One device combines smoke and CO detection.
• The three-pack provides three combination alarms.

How does wireless interconnection work, and is it Wi-Fi compatible?

When one interconnected X-Sense XP0H-WN detects smoke or carbon monoxide, all interconnected alarms sound at the same time. This shared alert helps people elsewhere in the home know promptly that an alarm has detected a hazard. The model supports wireless interconnection, but it does not connect through Wi-Fi and cannot be used with a base station.

• The simultaneous alert applies to alarms that are interconnected.
• Wireless interconnection is distinct from Wi-Fi connectivity.

What powers the alarm, and what should I know about the mounting bracket?

The X-Sense XP0H-WN uses a sealed lithium battery designed to power the alarm for 10 years. Its oversized mounting bracket measures 5.7 inches (145 mm) across and covers a wider area than typical small brackets, helping conceal old screw holes and ceiling marks. Before installing, compare the bracket size with the area occupied by your current device.

• The broad bracket can cover marks left by a previous alarm.
• ETL Listed; meets UL 217 and UL 2034 safety standards.

This three-pack suits households looking for combined smoke and carbon monoxide detection, with wireless alerts between interconnected alarms and a sealed battery designed for a 10-year operating period. It is a wireless-interconnection model, not a Wi-Fi or base-station-compatible alarm.
