The batteries are low: A blinking red light, usually accompanied by a loud beep, could mean the batteries in the unit are low. Consider adding fresh batteries and testing to ensure they're working. You need to replace it: Smoke detectors don't last forever.
The units should stop beeping once they are off the ceiling. Sometimes there is a residual charge that makes the alarm been for a few minutes. It should be possible to stop this by pressing the test button in the middle. Could it be the other alarms in the circuit making the beeping noises?

Low or Dead Batteries
Low batteries are the most common cause of chirping or beeping noises in a smoke alarm. It will usually occur at regular intervals of 30 seconds to one minute.
Typically, a red light that flashes every 30 to 60 seconds is a standard feature indicating that the smoke detector is functioning correctly and is actively monitoring for smoke. However, if the red light blinks more frequently or continuously, it may signal a problem.

Accumulation of Debris
A smoke alarm is a sensitive device that helps to detect smoke particles from different sources of fire. Debris such as dust or soot often produced by burning matter can accumulate on the gadget thereby triggering the alarm even when there is no actual fire.
Sometimes, smoke detectors will keep going off for no reason when they have reached the end of their life span. Fire alarms have a lifespan of about 10 years, after which they will need to be replaced. Smart smoke detectors can help eliminate some of the annoyances related to false alarms.
Press and hold the test button for 15-30 seconds. This should fully reset the smoke alarm and drain any charge left inside. Replace the battery.
The smoke detector will automatically reset itself after 10 minutes and re-sound an alarm if the smoke is still detected. If you want to manually reset the smoke detector so that the red blinking light will stop, you can press the test/silence button for a few seconds.
