X-Sense XP04 Combination Smoke and Carbon Monoxide Detector
-
- Fire & CO Detection in One Unit
- Equipped with photoelectric and electrochemical sensors to deliver protection from both fire and CO danger in one unit.
-
- AC Powered with Battery Backup
- If the power goes out, a battery backup will automatically activate to ensure constant monitoring.
-
- Smart Interconnection
- X-Sense XP04 combination alarms can be wired to build an interconnected system. When one alarm sounds, they all do!
-
- 3-Color LED Indicator
- Know your device’s status with the 3-color LED indicator (red, yellow, green) paired with audible beeps.
-
- Test/Silence Button
- An easy-to-push Test/Silence button blends seamlessly with the detector, making it easy to test the sensor or mute it in the event of a false alarm.
-
- Self-Check Function
- The detector will check its circuits, electronics, and battery level every 60 seconds to ensure it is functioning properly.
Dual Sensors, Enhanced Protection
Equipped with a photoelectric smoke sensor and an electrochemical CO sensor, this detector has been optimized to accurately detect smoke produced by smoldering fires and carbon monoxide leaks.
Smart Interconnection
X-Sense XP04 combination alarms can be wired to build an interconnected system. If one detects a dangerous situation and alarms, all the other detectors will go off too!
Test/Silence Button
The Test/Silence button ensures superb device performance 24/7 and mutes alarms with the quick and easy press of a button, giving you a sense of comfort and safety in your home.
3-Color LED Indicator
The LED light gives you a visual indicator of the detector’s working status. Green means standby mode, red means an alert, and yellow means a fault has been detected.
Stay Safe During a Power Failure
If a power outage occurs, the backup battery will activate, working much like a standalone detector and ensuring constant monitoring for smoke and CO.

FAQs
-
How do I know whether the alarm is working? Is there supposed to be a light blinking?
You can check the device's working status by looking at the LED indicator. In AC mode, the LED indicator light is solid green. In DC mode, the LED indicator flashes green once every 60 seconds, but if there is no power outage, please check the wire connection.
-
Does it work in hallways?
Of course! We recommend installing this detector in the hallway near your bedroom, so you will immediately hear the alarm sound when it is triggered.
-
How loud is this alarm?
The alarm is measured at 85 dB within 10 ft (3 m), which can be heard throughout your house.
-
What is the lowest carbon monoxide ppm level that the alarm can detect?
30 ppm. Whether an alarm will be triggered depends on the CO levels in the air. The following is a list of times and levels for when an alarm will sound: within 60–240 minutes at a level of 70 ppm, within 10–60 minutes at a level of 150 ppm, and within 4–15 minutes at a level of 400 ppm.
-
Is there a way to mount it?
Yes, you can mount it using the mounting bracket, 4 screws, 4 anchor plugs, and one AC power connector included in the box.
-
Does this have a photoelectric or an ionization sensor?
This alarm is equipped with a photoelectric sensor, which is more sensitive to smoldering fires than an ionization sensor. It allows you to detect and respond to smoke and fire as soon as possible.
