Product Overview

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.

FAQs (3)
Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?

The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall.

During a fire, smoke initially rises and then spreads horizontally. Placing the smoke alarm in the centre of your ceiling means that it is closest to all four points of your room. This ensures that you receive the earliest possible warning of a fire.

For more information, read our guide to positioning your smoke alarm and guide to which smoke alarms are best for each room.

Q. How do I fit my smoke alarm to the ceiling?

Smoke alarms can be either screwed to the ceiling using the holes on the base plate (screws provided), or fixed in place using either a self-adhesive sticky pad or a self-adhesive magnetic mounting kit.

Q. If the radio interlinking signal on one unit fails will the units still work as stand alone units.

Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.
