Three of my smoke alarms blink since i canged the batteries after one chirpped. the other tw have a steady gree light. why?


It would be nice to know if all the detectors are the same model and/or manufacturer. I have been in a number of homes where the smoke alarms have been replaced one at a time resulting in different models. If possible, please add a list of the models involved and ages of devices...if more than 10 years old, replace the unit.

Replaced 9 v batteries, units still chirping


This is the troubleshooting information from the kddie site. The problem is usually related to an older battery or improperly installed battery. You might also have to do a reset as described below. If battery and cleaning don't work, it might be time for a replacement - short money to keep you and your home safe.

  1. The battery may be loose, or improperly installed.
    Verify that a battery of the recommended type is securely installed. Make sure to use a battery with a use-by date no later than four to five years in the future. Check that the battery is snapped in completely so it cannot be shaken loose. It’s possible that battery connections may not be making good contact with the battery. Disconnecting and re-connecting the battery once or twice will likely fix this condition. On units with a front-load battery, be sure that the battery compartment door is closed completely as well. Loose white neutral wire can cause an echoing chirp. (From one unit to the next)

  2. The smoke alarm sensing chamber may be dirty.
    Dust and insects can collect in the sensing chamber of the alarm. An accumulation of dust in the sensing chamber can cause the unit to chirp. It is good practice to clean the smoke alarm when you change the battery. Static electricity from the ac quick connector attracts dust and can cause false alarms.

    Cleaning smoke alarms:
    To clean your alarm, remove it from the mounting bracket as outlined here. You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth. After cleaning, reinstall your alarm, verify the green LED is on and test your alarm by using the Test Button. If cleaning does not restore the alarm to normal operation, the alarm should be replaced.

  3. Check environmental conditions:
    • Humidity, steam and condensation can cause false alarms. Causes of condensation are:
      • Extreme temperatures changes.
      • High ambient humidity.
      • Unit being installed in an uninsulated electrical box mounted on a ceiling beneath an attic. If this condition exists you’ll want to move the alarm. Click here to see the correct alarm placement in your user’s manual found in our Download Center.
    • Check to see if there is a cooling/heating register, a ceiling fan or an open window within 3 feet of the alarm. If there is, move the alarm away from the source of the increased airflow. Click here to see the correct alarm placement in your user’s manual found in our Download Center.
    • Check the temperature of the room. Smoke alarms operate at 40 degrees to 95 degrees Fahrenheit. Carbon monoxide alarms operate at 40 degrees to 100 degrees Fahrenheit.

  4. Reset the alarm.
    Some current model smoke alarms have a processor that retains certain error conditions, such as a weak battery. The error condition should reset when the battery is replaced but sometimes it does not and must be manually reset to clear the error.

    To reset an AC unit with a battery backup:
    Turn off the power to the smoke alarm at the circuit breaker.Remove the smoke alarm from the mounting bracket and disconnect the power. Remove the battery. Press and hold the test button for at least 15 seconds. The unit may chirp or alarm for a few seconds before going silent.Reconnect the power and reinstall the battery. The unit will chirp once when the power is restored and should not chirp afterwards.

    To reset a DC only unit:
    Remove the battery. Press and hold the test button for at least 15 seconds. The unit may chirp or alarm for a few seconds before going silent.Reinstall the battery. The unit will chirp when the battery is first connected but should not chirp afterwards.

  5. An electrical condition may be causing the power to the unit to be interrupted.
    If the AC power to the unit is interrupted, the unit will chirp when the power is restored. This could be caused by power surges.
    If the chirping seems to occur at about the same time in the evening or morning, it could be due to a surge created when the power company switches electrical grids to meet demand. Check to see if the chirp (or chirping) occurs when something else in the house is turned on such as an exhaust or attic fan, a heater, etc. If the smoke alarm is connected to a circuit with such a device, the alarm may chirp when the other device is switched on. If this is the case and the device is plugged into a wall outlet, move it to another outlet on a different circuit. If it is a hardwired device, have an electrician investigate it. These conditions can be minimized by installing your alarms on a dedicated circuit in compliance with NFPA requirements.

  6. Replace the alarm.
    If none of these conditions exist and the suggestions don't alleviate the symptom, the alarm should be replaced. Age may be a factor. Smoke and heat alarms should be replaced every 10 years, and carbon monoxide and combination alarms should be replaced every 7 years. Most of our alarms have a 5 year warranty from date of purchase (check your user manual for details). A date code is stamped on the label attached to the back of the unit.

My First Alert Carbon Monoxide Alarm has failed


If the carbon monoxide detector chirps, the battery may be dead. New batteries can be defective. Check if the light is yellow when the alarm is chirping, it means the battery is low, replace with a new battery.

NEED TO KNOW HOW TO RESET A PRESTIGE ELVATCE CAR ALARM


REPRIORITIZING A TRANSMITTER’S PROGRAMMING:
To reprogram a receiver channel with a different transmitter button once a code has been stored, there will be two options:
  1. Enter the transmitter program mode of the receiver channel to be reprogrammed. Using any unused button or combination of buttons, push out the stored code by pressing the unused button until a long chirp is heard, then repeat 3 additional times. After this, you can add any desired unused transmitter button. This action erases only that particular receiver channel, all other codes will remain stored.
  2. Enter the transmitter program mode. Using any transmitter button press and hold until a long chirp is heard. If a single chirp or multiple chirps, (up to 7 chirps), are heard, the unit is indicating that the transmitter has already been programmed elsewhere in the receiver. Release the transmitter button and within 5 seconds press and hold until a long chirp is heard. This action forces the unit to erase all stored codes of that transmitter.
The unit then exits the program mode the siren emits the program mode exit chirp pattern. All transmitter buttons for that transmitter must now be reprogrammed. Any other transmitter stored in the unit’s memory still remain operational. If the button is released and not pressed again within the 5 second period, no change in programming has been made to the receiver channel. The programmer can move onto a different channel or erase the transmitter codes as described in 1 above.
