UltraFire ULL10RF Series Wireless Interlinked 10 Year Sealed Battery Smoke and Heat Alarm Kit - Scotland and England Compliant

Designed to provide home owners with an early warning of fire, this kit includes 4 UltraFire ULL10RF series alarms which can be wirelessly interlinked in a system of up to 15 individual alarms – if one detects a fire, all connected alarms will sound. The 3 ULLS10RF optical smoke alarms are great for most rooms not regularly exposed to steam, fumes, or dust, while the ULLH10RF heat alarm has been included for the kitchen where cooking fumes, burnt toast, or humidity could cause false activations in a smoke sensor. UltraFire ULL10RF series alarms all feature 10 year sealed lithium batteries, which won't need changing for their full lifespan, and a 10 year warranty for peace of mind.
