A smoke alarm in an unheated area of the house an attic, for instance can become too cold to reliably deliver an electrical charge during an abrupt decline in temperature.
Other causes may be hot air issuing from the bathroom after a steamy shower or heat not smoke from cooking in the kitchen. To avoid this kind of false alarm, reposition the smoke alarms that are in close proximity to the kitchen or bathroom door, or direct hot air away from alarm vents with a fan.
The small light sensor housed within certain types of smoke detectors can be quite sensitive. That means something as innocuous as a bit of ash, pollen, or dust—blown in through an open window, perhaps—can interrupt the light beam and set off beeping.
It makes sense to check the smoke detector straight away as soon as you hear an ear-piercing beep. Your carbon monoxide alarm may have gotten unplugged, or an aspect of your home security system may need attention.

Sometimes, a smoke detector siren is so loud, it may be challenging to pinpoint the location of the right device. So you may be checking the detector near your kitchen when the clamor is emanating from elsewhere in the home.
Some modern hardwired smoke detectors are smart devices that adapt to their environment. Trouble is, these advanced models tend to save errors to the processor, and when too many errors add up, they can trigger the alarm.
All this means is that the system needs a restart; doing so will delete saved errors and start the device with a clean slate. This chirping is normal and signals that the device is receiving fresh power. If the chirping continues, however, your detector might have a residual charge from the previous battery.
Take out the battery, hold down the test button for 15 seconds, and replace the battery. However, there is actually a technical explanation for this behavior. The phenomenon is a result of two factors:.
However, if they are weakening at night, they begin to run low and you should replace them. According to FEMA, a smoke detector should last up to 10 years.

Otherwise, you risk forgetting that the device is no longer working. In addition, it can take days for a battery to completely drain, and the chirping will continue throughout that time. Taking the battery out of a smoke alarm will not make it stop beeping. Even after the battery has died, the detector maintains a residual charge that will keep the chirp going for at least seven days. To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds.

An intermittent alarm is usually a random sound for several seconds and has a lower pitched tone. The battery pull-tab should be removed after AC power is provided to the device. The battery drawer should be totally closed for the battery to make contact with the terminals.
Note: Only the device with a low battery will chirp. The other interconnected alarms should be silent. The battery may not be completely making contact with the terminals in the alarm. Check to ensure the battery pull-tab or any other obstruction is completely removed. Security systems, monitors, carbon monoxide alarms, and other devices have a comparable low battery or alert sounds.
Other reason for a smoke alarm beeping or chirping erratically could be temperature fluctuations in the house. If you set the thermostat at an unusual very high or low temperature, the smoke alarm detects this and issue a sounding alert.
Another reason why the smoke alarm chirps could be if it detects hot air coming from the kitchen or bathroom. This could happen when you are cooking at high heat or someone opens the bathroom door soon after taking a hot shower. To avoid this kind of false alarms it is best to either move the smoke alarms in close proximity to the kitchen or bathroom door or use another means to ensure that the hot air does not reach the alarm vents.
