A red flashing LED about once every 5 minutes verifies operation. For models KF10, KF10LL, KF10R, KF20, KF20LL and KF20R the red flashing LED also verifies that a working battery is present.
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.
Most smoke detectors will give a red flashing signal to remind you that the battery needs replacing.
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.
The red indicator will flash rapidly to show an alarm condition for the alarm that has triggered. The 'Test/Hush' button will either silence false alarms (if briefly pressed) or to perform a self test (if pressed and held). In 'Test' mode the alarm will perform a self test and sound the horn.
Red light flashes every ten seconds to remind you that the alarm has been silenced. Double beep indicates that the alarm has automatically reset after approximately 10 minutes. Be Prepared Smoke and heat alarms properly installed and maintained are an essential part of a good home fire safety programme.
Flashing green light on smoke detector
Many smoke detectors use a green light in place of a red light. For example, a blinking green light could be trying to tell you that your batteries are low. Some hard-wired detectors also use a flashing green LED light as part of an alternating current (AC) power upcycle.

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 your smoke detectors are yellowing, chirping non-stop, or going off unexpectedly, it's time to call in our electrical pros from Integrity Home Solutions. We can inspect and replace hardwired smoke detectors or install them if you don't have them in place already. Don't take a chance on your family's safety.
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.
After 10 years of use, the Kidde Firex Smoke Detector, Battery Powered, Smoke Alarm needs to be replaced. UL Certified with a 10-year limited warranty. Meets requirements of UL217, NFPA72, The State of California Fire Marshall, NFPA 101, FHA, & HUD.
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.
Why does my FireX smoke alarm keep going off? The most common cause of a FireX smoke alarm going off (aside from detecting smoke) is a low battery or unreliable power supply. You should also check for any dust, dirt or debris near the smoke alarm.
The smoke detectors needs to have functioning batteries in order to work properly. Press the button on the face of the one that's blinking to RESET. If this smoke produces a chirp about 20 seconds after a RED flash it indicates that the smoke sensing chamber has failed and the smoke needs to be replaced.
This is typical behavior for a hardwired smoke detector that has battery backup. The steady green light indicates that the detector is receiving line power. The short red flash every 30–60 seconds indicates that the internal self-test for proper functionality has passed.
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.
Several common causes can explain why your hard-wired smoke detector is beeping: Low battery: Even hard-wired smoke alarms have backup batteries that need replacing periodically. A low battery can cause that annoying beeping sound. Dust buildup: Dust and debris inside the smoke detector can trigger false alarms.
After 8 minutes your alarm will automatically return to full sensitivity. The red LED on the front of the alarm will flash once every 8 seconds to show that it is in Silence mode.
Hardwired smoke detectors run on electricity, but they also have a backup battery for power outages. When you hear a hard-wired smoke detector beeping, it means you need to replace its battery.
The smoke alarm is desensitized by pushing the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and the red LED blinks every 10 seconds. This indicates that the alarm is in a temporarily desensitized condition.
A red blinking light is the unmistakable warning that the detector has sensed smoke or fire. An amber or yellow blinking pattern typically signals a low battery or other maintenance issue.
