While it is generally recommended to use smoke detectors from the same brand for interconnected systems, some brands offer compatibility with other brands, but this is not always guaranteed. Interconnecting different brands may cause compatibility issues and the alarms may not trigger correctly or at the same time.
Here is a more detailed explanation from anka security:
Interconnection technology:
Smoke detectors can be interconnected using either a hardwired connection or wireless technology. Hardwired detectors use a red wire to connect them together, while wireless detectors communicate via radio frequency.
Brand-specific protocols:
Different manufacturers often use different communication protocols for their interconnected systems. This means that the signals sent by one brand of detectors may not be recognized or correctly interpreted by another brand of detectors.
Potential issues:
When different brands are mixed, there is a risk that the detectors will not trigger together in a fire, which can delay evacuation and increase the risk of injury.
Manufacturer recommendations:
Manufacturers like First Alert recommend sticking with the same brand for interconnected systems to ensure proper functionality and reliability.
Exceptions:
Some brands, such as First Alert and BRK, have compatible models that can be interconnected. Additionally, some systems may offer adapters or bridge devices to connect different brands, but it is critical to verify compatibility with the manufacturer.
Testing:
Even with compatible brands, it is recommended to regularly test the interconnect functionality using the test button on the alarm to ensure that all units are triggering as expected.
