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. An end-of-life or low-battery warning. To indicate the alarm is in hush mode or that there is a fault with the alarm.
Why is my smoke detector blinking red, but there's no sound? If your smoke detector blinks red but no alarm goes off, the device could be warning that the battery levels are low. While that's a primary reason for a blinking red but silent smoke detector, much depends on the particular make and model.
The smoke detector battery is low
If the light flashes every minute or so, a low battery is likely the culprit. Smoke detector batteries generally last around eight to 10 months, but they can sometimes last a little longer.
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.
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.
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.
If the unit malfunctions, the red LED light will flash and the unit will chirp every 30 seconds indicating a system problem. If the red LED flashes every 60 seconds WITHOUT an audible chirp, this is the pre-warning that the battery will soon need replacing. The alarm is battery-operated with a 9V battery.

After smoke levels drop below alarm levels, the “Smoke” Red LED will begin to flash On for 2 seconds/Off for 2 seconds. It will continue to flash or “latch” for about 15 minutes, to give you time to determine which unit initiated the alarm.
They are usually mounted in a high position located in the living room, hallway or bedrooms. You will notice two different lights on your smoke alarm: A steady green light shows the alarm is being powered. A red light that flashes once a minute shows the alarm is working.
3 If the red LED flashes at a separate time from the chirp, a fault is indicated. If within warranty contact Technical Support. Otherwise replace immediately. If troubleshooting does not resolve the problem and you believe the alarm is still faulty - remove the alarm and replace.
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.
On many carbon monoxide alarms, the red light flashes to show the CO alarm is properly receiving battery power. For these alarms, when you do not see the red light flashing, change the batteries in the alarm immediately.
A smoke or heat alarm is sounding for no reason:
Find the alarm with the red light rapidly flashing. Press its 'Hush' button to silence. If that does not silence it, clean the alarm using a vacuum. Wait for 10 minutes and the issue should be resolved.

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.

Your cell phone can offer some help with hidden camera detection. You can use the flashlight to search for glinting lenses in the dark, and some apps claim to detect hidden cameras by using different technologies like Bluetooth and infrared detection to pick up on radio and other frequencies cameras emit.
Red LED Indicator: The red LED will blink in conjunction with the alarm sound. Therefore, the red LED will blink during a smoke alarm, a low battery mode chirp, a unit error mode chirp or at end of unit life. Fault Mode Indicator: These alarms monitor strategic functions of internal electronics and sensors.
