Thank you for the correction, you’re right. I got it mixed up with the status LED that some/most(?) smoke detectors have that will periodically blink to show that it’s active.
Regardless, a smoke alarm blinking red is to be expected, and doesn’t mean that it needs to be tested. Most of them will make a loud ping to notify the user that it requires attention, as you can’t expect people to notice the blinking LED alone.
That mean the smoke detector need to be tested. Push the button for testing and the light, after, will be a hard green, no flashling.
No my smoke detector had an ‘operational light’. It flashed every 30 seconds or so, so you knew it didn’t have a dead CPU or so.
Not if it is a photoelectric smoke detector, which is the only type you should have unless you got a good reason for ionisation smoke detector.
The blinking is the smoke detector checking for smoke particles.
photoelectric detectors use infrared LEDs. and they are inside the detector, shielded so stray light will not cause any problems.
Any red LED you see on a smoke detector is for statuses, not detecting

it would be nice if there were smoke detectors that didn’t have flashing lights during normal operation.
Well, the problem with that is that a completely dead smoke detector does also not blink
perhaps a steady faint green glow?
