The main problem with smoke alarm replacement is remembering when you last installed a new one and we all know how fast time flies. Luckily, a lot of new devices have a built-in “end of life warning” that will indicate the need for replacement. The sound your system makes will be unique to your device but it will likely be similar to the low battery warning sound. Check the manual (if you can find it) or have an internet search of the model number to identify the sound.
You can also find an expiry date on the side of the device.
