Other devices have similar low battery chirps or warning tones that sound like the chirp our alarms make. Your batteries may not be fresh.. Understanding Your First Alert Alarm.

However, the beeping can sometimes indicate minor issues rather than an emergency. Here are some common reasons your First Alert alarm might be beeping: Low Battery: One of the most.
