The manufacturer may have included a blinking red light to let you know it's time to test the alarm again. The batteries are low: A blinking red light, usually accompanied by a loud beep, could mean the batteries in the unit are low. Consider adding fresh batteries and testing to ensure they're working.
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.
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 CodeRED Photoelectric Smoke Alarm is best for detecting slow smouldering fires. It features a low-battery warning signal and an extra-loud warning tone. This smoke alarm comes included with a 9V battery. It is an ideal choice for new and renovated homes.
False alarming is generally caused by environmental or installation issue. This includes: Insects and insect ingress or dust. Humidity.
Code Red indicates smoke or fire; Code Black indicates a bomb threat or active shooter scenario, and Code Blue refers to a cardiopulmonary arrest. Colors, numbers, or other designations may follow a code announcement to identify the type of emergency that is occurring.
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.
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.
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.
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.
The color code for all newly installed fire alarm system conductors shall be as follows: INITIATING DEVICE CIRCUIT shall be red and black. Red shall be positive and black shall be negative [IDC/SLC]. NOTIFICATION APPLIANCE CIRCUIT shall be blue and white.
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.
To reset the Alarm Controller, use a screwdriver to press the House Code button 5 times. The red LED will flash 10 times to indicate memory has been reset.
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.
A blinking red light on a smoke and CO2 alarm can mean a few different things. It could mean that the batteries are low, that the unit needs to be replaced, or that there is smoke or carbon monoxide present. If the green light is still on, it's likely that the unit is still working properly.
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.
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.
Low Battery: One of the most common reasons for a smoke detector blinking red is a low battery. Most smoke detectors will give a red flashing signal to remind you that the battery needs replacing. Accompanying this, you might hear a chirping sound at regular intervals.
A fire alarm is a comprehensive fire safety system. A smoke detector is just one component of a fire alarm. And a fire alarm only blares an alarm when its smoke detector component is activated. A smoke detector is designed for use in residential dwellings.
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.

A Guide To Visual Alarm Colours
Red indicates 'stop' or a hazard/danger is present. Amber beacons encourage awareness.
RED codes are used to confirm trades on MarkitSERV and other trade matching and clearing platforms, facilitating straight-through processing. Counterparties can rapidly agree on transactions and have confidence in the integrity of the underlying CDS reference data.
