Black+Decker Smoke Alarms - 2 Pack

The lithium battery is sealed and designed to last for 10 years. No battery replacements are needed during the lifespan of the alarm.

This alarm uses an advanced optical sensor, which is particularly effective at detecting slow, smoldering fires. It is also designed to reduce false alarms from cooking fumes.

No, this alarm does not require any wiring. It comes with a mounting base and screws for a simple, DIY installation.

It is recommended to test the smoke alarm at least once a month by pressing the test button.

The alarm will emit a specific end-of-life signal to indicate that it needs to be replaced. The entire unit should then be replaced.

While the advanced optical sensor reduces false alarms, it is generally recommended to install smoke alarms away from kitchens and bathrooms to prevent nuisance alerts from cooking or steam.

This smoke alarm is certified to BS EN 14604:2005+AC:2008 and is fully compliant with CE and UKCA standards.

Ensure the alarm is properly twisted onto its base. If the issue persists, the unit may be faulty and needs replacement.

The optical sensor may be too close to a heat or steam source. Relocate the alarm to a different area, such as a hallway or living room, away from kitchens and bathrooms.

This usually indicates the end of the unit's 10-year life. The alarm needs to be replaced. Follow the end-of-life signal instructions.

Ensure there are no environmental factors (like dust or insects) near the sensor. Clean the exterior gently with a dry cloth. If the problem persists, contact customer support or replace the unit.
