FAQ
What makes these alarms 'interconnectable'?+
These alarms communicate wirelessly using a dedicated protocol. When one detects smoke or carbon monoxide, it immediately alerts all linked devices, providing comprehensive coverage throughout your home. This coordinated response is faster and more effective than individual standalone alarms.
Are the batteries long-lasting?+
Yes, they utilise long-life lithium batteries designed to last up to 10 years. The battery status is clearly displayed on the alarm itself, ensuring you’re always aware of their remaining life and can easily replace them when needed.
Do I need a hub to connect these alarms?+
No, this model operates without a hub. The alarms communicate directly with each other wirelessly, simplifying setup and eliminating the need for additional equipment or connectivity costs.
What kind of testing have these alarms undergone?+
These alarms are rigorously tested to meet BS 5839-1:2017 standards, ensuring reliable performance. They undergo regular sensitivity tests and false alarm mitigation procedures to guarantee accuracy and minimize nuisance alerts.
How many alarms can I link together?+
You can link up to eight of these interconnected alarms to provide complete protection for your property. The system is designed to scale with your home's size and layout, offering flexibility and peace of mind.
Are the alarms tamper-resistant?+
Yes, they feature a robust tamper detection mechanism. If someone attempts to disable or remove the alarm, it will trigger an immediate alert, notifying you of a potential security breach and ensuring continuous monitoring.
What is the range of the wireless connectivity?+
The wireless range between alarms is up to 80 metres in open space. However, walls and other obstructions may reduce this range; we recommend placing alarms strategically for optimal coverage.
How do I install these alarms?+
Installation is straightforward with included mounting hardware. The alarm can be easily attached to a wall or ceiling using the provided screws – no specialist tools are required. Clear instructions are included for simple and quick installation.
Are there any specific environments where these alarms may struggle?+
While designed for general use, high humidity environments (bathrooms) or areas with frequent steam generation might cause occasional false alarms due to condensation. Placement away from direct heat sources is also recommended for optimal performance.
What happens if one of the alarms fails?+
Because the alarms are interconnected, a failure in one unit will immediately alert you to potential danger. The system continues to operate with the remaining functional alarms, providing ongoing protection until replacement.
