FAQ
What type of batteries do these alarms use?+
These alarms utilise long-life lithium batteries, offering up to 10 years of continuous operation. Replacing the batteries is straightforward and only needs to be done every 10 years - a simple process with clear instructions provided.
How sensitive are the smoke sensors?+
The smoke sensors employ photoelectric technology, known for its sensitivity in detecting smoldering fires – a common cause of house fires. They’re designed to respond quickly to even trace amounts of smoke, providing an early warning system.
Do these alarms have tamper protection?+
Yes, they feature a tamper-proof cover that prevents false alarms and protects the sensitive electronics inside. If removed, the alarm will immediately sound to alert you to potential tampering.
What happens if the power goes out?+
The integrated battery backup ensures continuous operation of both the alarm and the digital display during a power outage – maintaining vital monitoring functionality.
Are these alarms suitable for flats or apartments?+
Absolutely. These alarms are designed with a wide operating range and can be installed in various environments, including flats and apartments. However, consider placement away from kitchens to minimise false alarms caused by cooking steam.
How often should I test the alarm?+
We recommend testing your smoke and carbon monoxide alarms at least once a month – using the built-in test button. This ensures all components are functioning correctly and you’re familiar with the alarm's sound.
What is the decibel level of the alarm?+
The alarm emits a piercing 85dB sound, exceeding the minimum requirement for effective audible warning in UK legislation. This high-volume alarm ensures it will easily cut through background noise.
Are these alarms compatible with smart home systems?+
Currently, these premium alarms do not directly integrate with popular smart home systems. However, future compatibility is being explored and updates may be released over time.
What does the digital display show?+
The digital display shows the current carbon monoxide level in parts per million (ppm) alongside a visual indicator of the alarm’s status – indicating whether it's operating normally, detecting an issue, or requiring battery replacement.
How do I clean the alarms?+
Simply wipe down the exterior with a soft, dry cloth. Do not use cleaning products or spray directly onto the unit to avoid damaging the sensors and electronics.
