Why Is My Smoke Detectors Flashing Red at Times?
2022-06-20
People might wonder, is there something wrong when the red LED indicator of the smoke detector flashes at times?
Is there a fire occurring, or is the device broken?
Neither of them is correct. In fact, it is a normal situation for the smoke detector to flash regularly. When it does, it means the smoke detector is on and it is on its duty, checking its battery power. The smoke detector also interacts with the control panel to exchange information. Whether the smoke detector faults or alarm is done through interaction with the control panel.
Generally speaking, the smoke detector works well when its red LED indicator flashes on a regular base. But once the red LED indicator is always on, there must be a fire detected. In some countries, people tend to use smoke indicators that have LED indicators in two colors, red and green. For these smoke detectors, when the green LED indicator is flashing, it means the detector is working. When the red LED indicator is always on, it means the smoke detector senses a fire. And ASENWARE’s designs for different kinds of detectors can fulfill different countries’ needs.
