FAQ
How many alarms are included in this kit?+
This kit contains two smoke detectors and two carbon monoxide detectors, offering full coverage for a small to medium sized home. Additional units can be purchased separately to extend the system's range.
What type of batteries do these alarms use?+
Each alarm utilises three standard AAA alkaline batteries. We recommend using high-quality, long-life batteries for optimal performance and extended battery life. Replacement packs are readily available.
Do the alarms require a Wi-Fi connection?+
Yes, the Wireless Interlink system requires a 2.4GHz Wi-Fi network to function correctly. The app allows you to monitor and control the alarms remotely, but basic functionality (such as audible alarms) remains operational even without Wi-Fi.
How far apart can the alarms be placed?+
Ideally, alarms should be no more than 30 metres apart for optimal wireless communication. However, placement is dependent on your home's construction and potential interference; testing is recommended.
Are the alarms tamper-proof?+
Yes, each alarm features a tamper seal that breaks if someone attempts to disable or remove the unit. This provides clear evidence of tampering and alerts you immediately via the app.
How often should I replace the batteries?+
The system automatically monitors battery levels and sends low-battery warnings to your smartphone. However, we recommend replacing the batteries every two years as a precautionary measure, even if they haven't reached their end of life.
Can I extend the range of the wireless network?+
While not directly supported, using multiple access points or extending your existing Wi-Fi network can improve signal strength and potentially increase the effective range of the alarm system. Consider a mesh Wi-Fi system for optimal coverage.
Are these alarms suitable for rental properties?+
Yes, this system is ideal for rental properties as it’s easy to install and remove. The included mounting fixings allow for secure attachment to walls, and the low battery alerts provide added peace of mind for both landlords and tenants.
What happens if one alarm fails?+
The system continues to operate normally with the remaining alarms. If one unit fails, it will trigger a persistent alert until resolved, ensuring continued protection throughout your home. It does not disable other alarms.
Do these alarms have test buttons?+
Yes, each alarm features a clearly marked test button for regularly verifying its functionality. Testing should be conducted at least once a month to ensure accurate detection and reliable performance.
