The red LED on the front of the alarm will flash once every 8 seconds to show that it is in Silence mode.

If an alarm is sounding, it is warning you of a potentially hazardous situation.
The flashing red light is an indicator of the good working condition of your fire alarm; it means that your setup is working and has power. Also, the purpose of blinking light depends on the brand and model of your fire alarm. So you can clarify this at the beginning of the fire alarm system installation.
Low Battery: This is the most common reason for a red blinking light on a smoke detector. Even if you've just installed it, the battery may not have been fully charged, or it may have drained during installation. Replace the battery with a fresh one and see if the blinking stops.
Why Is My Smoke Detector Blinking Red? A red light will flash all the time if it's operating correctly, but only about once or twice every minute or so. If it's blinking faster than that, it probably means it's functioning in “hush mode,” which means the alarm was silenced for some reason.
In the event of a known false alarm your smoke alarm can be temporarily silenced by pressing the central test button. Your alarm will automatically return to full sensitivity within 10 minutes.

Many smoke detectors use an LED light to show you that everything's working properly. If your device's on/off button has a stale red light, it likely means the system is working properly. Some detectors will even use a light that flashes periodically to tell you they're working.
Why did my fire alarm randomly go off in the middle of the night? This is likely due to one of the common causes like low battery, dirt buildup, humidity, or insects interfering with the sensor. Test the alarm and clean it thoroughly to try and resolve the issue. Make sure batteries are fresh and secure.
In a smoke detector the red-light flashes once every 5 seconds under normal operation with its filter intact. A hidden camera may have different light flashing patterns. A hidden camera smoke detector may not have an indicator at all. Normal smoke detectors are completely enclosed with only the sensor window open.
Sometimes, smoke detectors will keep going off for no reason when they have reached the end of their life span. Fire alarms have a lifespan of about 10 years, after which they will need to be replaced. Smart smoke detectors can help eliminate some of the annoyances related to false alarms.
Flashing Red
This is completely normal across all alarms as long as there is no sound. If this is accompanied by a chirp every 45-60 seconds then the battery may need replacing.
Here are some examples of why smoke detectors periodically have a flashing red or green LED light without an alarm sounding; To indicate that the alarm is receiving power and is operating normally.

For some units, a green light flashing every 5 seconds signifies that the device is in “battery only” mode, powered by AC. When the detector senses a smoke or carbon monoxide hazard, the green light might become steady, whereas in “hush” mode, it may flash every 2 seconds.
Your alarm manufacturer may have included a blinking red light to let you know it's time to test the alarm again. The Batteries are Low: Usually accompanied by a loud beep, a blinking red light could mean the batteries in the unit are low. Consider adding fresh batteries and running a test to make sure it's working.
The most common reason for a false alarm is a dead smoke detector battery. Without holding it, press the button on the front of the panel to test the battery. If the alarm sounds loudly and clearly, it's good to go. If there is no sound, or the alarm is quiet, slurred, or bending in pitch, replace the battery.
Verify It's Not a False Alarm
Read any notifications or messages appearing on the keypad display (if it's nearby) and then investigate, however don't put yourself in danger to do so. If you suspect that there is an actual threat in the house, find a safe place to wait for the authorities.
Incorrectly attached to baseplate If correctly attached to the baseplate, your alarm should show a green LED, with a red LED flash every 30‑45 seconds. If this is not the case, your alarm is not fitted correctly. We recommend detaching the alarm from the baseplate and reattaching to stop the beeping.
Press the 'hush' button for 3 seconds to silence the alarms. This will silence the alarm for up to 10 minutes. If the alarm is still sounding, you will need to disable it.
