Simple Installation, Reliable Protection

Battery operated smoke detectors give you peace of mind with minimal fuss. You can install these units in minutes using the included screws or mounting pad. No electrician needed, no rewiring required - just position, secure, and you're protected.

Our range includes optical smoke alarms that excel at detecting slow-burning fires. The UltraFire UBS1 runs on a single 9V battery and comes with our exclusive 5-year warranty. For areas where cooking fumes or dust might trigger false alarms, heat alarms like the UltraFire UBH1 provide reliable protection powered by two AA batteries.

Long-life options eliminate the battery replacement headache. The UltraFire ULLS10 features a sealed 10-year lithium battery that never needs changing. When the alarm reaches its end of life, simply replace the entire unit.

Where Battery Detectors Work Best

Bedrooms, living rooms, and hallways benefit from optical smoke alarms that respond quickly to smouldering fires. These areas contain soft furnishings and fabrics that create lots of smoke when they burn.

Kitchens and garages need heat alarms instead. These spaces produce steam, dust, and cooking fumes that can cause false alarms with smoke detectors. Heat alarms respond to temperature rises rather than particles in the air.

Upgrading Your Protection

Radio-interlinked battery alarms take your safety further. When one alarm detects danger, all connected alarms sound throughout your property. The UltraFire ULLH10RF offers this wireless connection with a sealed 10-year battery.

For landlords, sealed battery models prevent tenants from removing batteries. These tamper-proof designs comply with Grade F1 standards and provide consistent protection throughout their lifespan.

Our comprehensive smoke alarm range includes options for every property type and budget. Professional advice helps you choose the right system for your needs.

Regular testing keeps your family safe. Press the test button weekly and replace batteries when the low-battery chirp sounds. For ongoing maintenance reminders, our expert guides provide essential safety information.

Ready to protect your home? Browse our battery smoke detector range today and invest in your family's safety. Our customer service team stands ready to help you select the perfect fire protection solution.
