Low Batteries
Battery-operated fire alarms are very common nowadays. If you have a battery-operated alarm, you can face some issues because of the batteries. In simple words, the system can blink red if it has low batteries.

Old Smoke Detector
Besides old batteries, the system can have an issue if it’s quite old. Usually, a smoke detector’s normal lifespan is within 10 years. So, if the system is already 10+ years old, it’s time to get a new fire alarm.
