BLACK+DECKER Mains Smoke Alarm 1 interlinked unit 🔥
Description:
This mains-powered smoke alarm with battery backup gives continuous protection in living areas, bedrooms and hallways, combining wired interlinking with a 9V alkaline battery so the unit keeps working during power cuts. It uses an optical sensor to detect slow, smouldering fires quickly, making it suitable where early smoke detection matters for peace of mind.
Key Points
The alarm includes a large, easy-to-press test button for routine checks and an LED memory indicator that flashes for 72 hours after activation, helping you identify which unit was triggered. Installation is simplified by the FAST FIX easy install base, which allows secure mounting and straightforward wiring for interlinked systems without complex procedures. The design aims to reduce nuisance alerts from cooking fumes and steam, though avoid siting the device directly in kitchens or immediately next to bathrooms to limit false alarms. 🔧
Concerning longevity, the manufacturer states a 10-year operational life for the unit, which reduces the need for frequent replacement. The device is Kitemark certified by the British Standards Institute to BS EN 14604:2005+AC:2008, so it meets recognised British safety requirements. A battery backup supports continued operation during outages and ensures the alarm remains active while mains power is unavailable. 🔋
Technical Specifications
- Name: BLACK+DECKER Mains Smoke Alarm
- Power: Mains powered with 9V alkaline battery backup
- Sensor: Optical sensor for detection of slow, smouldering fires
- Lifespan: 10-year operational life, according to the manufacturer
- Certification: BSI Kitemark to BS EN 14604:2005+AC:2008
Usage Recommendations
Place the alarm on ceilings or high on walls in circulation areas such as hallways and living rooms, and ensure a reasonable distance from cooking appliances to avoid frequent false alarms. Interlinking multiple units provides whole-home notification, which is particularly useful in larger or multi-storey properties. Regularly test the alarm using the large test button to confirm both mains and battery functions, and replace the unit at the end of the stated operational life to maintain compliance with the certification guidance.
Positive Aspects
The combination of mains power and battery backup offers reliable continuous protection, and the fast-fix base reduces installer time and effort. The memory indicator is helpful for post-incident checks, and the optical detection method is well suited to slower, smouldering fires that might otherwise go unnoticed during the early stages. Consider that optical sensors may be less responsive to very fast flaming fires, so pairing with a heat detector in some locations could provide more comprehensive coverage.
