Product Information

Full details

The X-Sense SD11 Smoke Alarm is an essential safety device designed for homeowners, renters, and property managers seeking reliable, long-term fire protection for bedrooms, hallways, and living areas. Its standout benefit is the 10-year built-in lithium battery, which eliminates the need for frequent battery changes; however, users should note that once the decade-long lifespan is reached, the entire unit must be replaced rather than just the battery.

FAQs

How do I know when the battery is dead?

The X-Sense SD11 is designed to last 10 years. Near the end of its life, the device will emit a periodic chirp to indicate it needs to be replaced.

Can I replace the battery in this alarm?

No, the battery is sealed within the unit to prevent tampering and ensure longevity. The entire alarm should be replaced after 10 years.

Where should I install the SD11?

It is best installed in hallways, bedrooms, and main living areas. Avoid placing it in kitchens directly above stoves, in bathrooms, or near HVAC vents.

What does the red LED indicator mean?

A flashing red LED indicates the alarm is powered and functioning correctly. During an alarm event, it flashes rapidly.

Is this alarm suitable for high-humidity areas?

No, moisture can cause false alarms or damage the sensor. It should be used in dry, indoor residential areas.

Troubleshooting

The alarm is sounding for no apparent reason.

Press the silence button to mute the alarm, and ensure there is no steam, dust, or insect interference near the sensor chamber.

The device fails to sound during a manual test.

Ensure the device is properly locked into the mounting bracket, which activates the battery. If it still fails, the unit may have reached its end-of-life.
