Smoke alarm or
failure
Reset after failure:
Briefly press alarm / reset button. KRM-X immediately restarts

Reset after alarm:
Press and hold the alarm/reset button for at least 2 seconds until the
red alarm light in the button goes out. KRM-X will start again after

the button is pressed, the smoke detector is still filled with test
gas/test spray/smoke and cannot be reset. In that case, blow out the
smoke from the detector or wait.
