Safety notice: Smoke alarms are life safety devices. Install in accordance with the manufacturer’s instructions and applicable UK guidance, test regularly, and replace the complete alarm when the end of life signal sounds.
Suitable locations: Designed for bedrooms, living rooms, hallways and landings. For kitchens and garages, a heat alarm is generally more appropriate because cooking fumes and steam can cause nuisance activations.
Installer benefit: The sealed lithium battery lasts for the full 10 year alarm life, helping reduce routine maintenance visits and avoiding the inconvenience of replaceable batteries.

Frequently Asked Questions
Where should this smoke alarm be installed?
This optical smoke alarm is intended for bedrooms, living rooms, hallways and landings. Always follow the manufacturer’s installation instructions and relevant UK fire safety guidance.
Does the battery need replacing?
No. The sealed lithium battery is designed to last for the alarm’s full 10 year life. When the end of life warning sounds, replace the complete alarm.
Can I silence a nuisance alarm?
Yes. The Test/Hush button can temporarily silence nuisance activations, for example caused by steam or aerosols. Never disable or remove a smoke alarm as a long term solution.
Is this alarm suitable for a kitchen?
A heat alarm is generally more suitable for kitchens because cooking fumes and steam can trigger a smoke alarm. This model is best used in circulation areas and living spaces.
How often should the alarm be tested?
Test the alarm regularly using the Test button, following the manufacturer’s user guide. Regular testing helps confirm that the 85 dB sounder and sensing system are working correctly.
What does the end of life warning mean?
The end of life notification indicates that the alarm has reached the end of its 10 year service life. The complete unit should be replaced, not just the battery.
