The green AC Power On Indicator should be lit when the alarm is operating from AC power.
The lack of the green light means that there is no power to the unit. Check that the fuse is back on. If it is then you need the electrician to sort out your wiring. The alarm might have been fitted to the part of the lighting system that is switched.
Green and red LED lights that indicate normal operation and alarm status o Green Light: The green LED will flash every 30 seconds to indicate the unit is operating properly.
After installation, you can test your smoke alarm by pressing on the test button for at least 10sec. This will trigger the alarm. To maintain your smoke alarm, vacuum around the smoke chamber regularly. Dust may accumulate inside the mesh even if it looks clean outside.
Blinking Red Light: Usually means the smoke detector is working properly and is in standby mode. Steady Red Light: Often indicates that the alarm is sounding or that there is an issue (like a low battery or a malfunction). Green Light: Typically indicates that the smoke detector is powered and functioning properly.
If you do not see the red light flashing, change the batteries in the alarm immediately.
It's Working Properly: Some brands use an occasional red blinking light to indicate the unit is working properly.
According to the Kidde Smoke and Carbon Monoxide Alarm user guide, a red LED light blinking every 15 seconds indicates a low battery condition. This means that the batteries in your smoke detector need to be replaced.
How do I know if my smoke alarm is working? Test it! Push the test button on the front of the unit and it should emit a loud beeping sound for as long as the button is depressed.
Kidde recommends replacing your smoke alarms every5/ 10 years, and carbon monoxide alarms every 7/10 years. If you don't know how old your alarm is, look for the manufacturing date code on the back of the alarm(s) or simply replace them to avoid any danger.
To find the initiating unit, look for one that is flashing RED or GREEN at least once every second while in alarm mode, then follow the reset procedure on that unit. If the alarm stopped on its own before you could find that flashing light, the initiating unit will flash for 1.5 seconds every 10 seconds.
Whenever the alarm is operating, the green Power LED flashes every 30 seconds to indicate the unit is monitoring for CO. If the alarm senses dangerous levels of CO, the red Alarm LED will flash and the alarm will emit an audible alarm pattern.
A “chirping” sound means that it's time to change batteries. Because alarm sensors wear out, replace each alarm at least every 10 years. Also, alarms have labels showing when they were made. If you don't see a label, the alarm is old and must be replaced.
Green Light: The green LED will be lit continuously or flash every 30 seconds to indicate the unit is operating properly. In Hush® mode the LED blinks every 2 seconds and once per second if it is the initiating alarm.
Mains-powered smoke alarms should have a solid green light to indicate the power is on, while battery-operated alarms should have no visible lights. If there are any coloured or flashing lights, or the unit is sounding in anyway, there could be several reasons for this: Low battery. Low battery back-up.
Check the green mains power light is on. If not, check fuse, circuit breakers and wiring connections. If the green light is off, the Lithium cells will deplete after some months without mains and will need to be recharged. If turning on the mains fails to stop the beeps, a fault may exist.
The green light on my smoke alarm has gone out, what does this mean? The AC power has been interrupted. Check the circuit breaker and AC wiring to correct the problem.
You can test your smoke alarm by pushing the Test/Hush button on the cover and holding it down for a minimum of 5 seconds. This will sound the alarm if the electronic circuitry, horn and battery are working.
Use a Flashlight
Put out the room lights and point your flashlight at the smoke detector. A camera situated within the device will probably bounce back light. Search for tiny reflections and reflections that shouldn't appear under normal light conditions.
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.
First, locate the reset button on your Kidde smoke alarm. This is usually located on the front or side of the unit. Press and hold the reset button for at least 5-10 seconds. You may need to use a small tool, such as a paperclip or a pen, to press the button.
The unit shall include the Hush® feature that silences the unit. By pressing the Hush® button, it will desensitize the unit for approximately 7 minutes if a nuisance condition occurs.
You're exactly right. The light blinks green at first, then some of them typically change to Amber. Then, will blink red as the battery goes down. When the battery gets really low the red light will stay on.
