FAQ
What type of batteries do these use?+
These alarms utilize long-life lithium batteries. They typically last around 10 years and require minimal maintenance - replacement is only needed when the low battery signal activates.
How many smoke detectors are included in a pack?+
A standard pack contains three individual Smoke & Carbon Monoxide Alarms, allowing you to monitor multiple areas of your home effectively. Additional packs can be purchased separately.
Do the alarms have a test button?+
Yes, each alarm features a dedicated test button for regularly checking the functionality of both the smoke and carbon monoxide sensors. This is recommended monthly to ensure optimal performance.
What happens if one alarm goes off?+
Due to the RadioLINK+ connectivity, when one alarm detects either smoke or CO, all connected alarms will immediately sound their audible alerts, providing a comprehensive warning throughout your home.
Are these alarms tamper-proof?+
The Wireless RadioLINK+ Smoke & Carbon Monoxide Alarms incorporate a tamper switch. If the alarm is tampered with, it will continuously emit a loud beep and the corresponding alarm unit will signal an issue.
How far apart can I place the smoke detectors?+
We recommend positioning each alarm no more than 30 meters from another to ensure reliable communication via the RadioLINK+ technology. Larger homes may require additional units for optimal coverage.
Do these alarms have a battery backup?+
Yes, each unit has a built-in battery backup that will activate during a power outage, ensuring continuous monitoring and alerting.
Are the displays easy to read in low light?+
The digital displays are designed with high-intensity LED backlighting for clear visibility even in darkness. This ensures you can quickly assess the alarm status at any time of day or night.
What is the decibel level of the alarms?+
The audible alarms have a sound pressure level (SPL) of 85dB, which meets and exceeds UK regulatory standards for fire safety. This ensures they are loud enough to be heard clearly throughout your home.
Are these alarms suitable for flats or apartments?+
While effective, due to potential interference from neighbouring properties, we recommend using these alarms in larger homes or properties where the signal strength is less likely to be disrupted. Regular testing is crucial regardless of location.
