Fault
If the smoke alarm cannot work normally, please follow the below procedures to troubleshoot.
1.
Smoke alarm does not sound, please check whether the alarm is properly attached to the mounting bracket.
2.
Battery runs out,(Refer to From1) Please replace battery immediately.
3.
Faults caused by dirt, dust and oil etc.(Refer to Form1) Please clean the smoke detector correctly.
Mute and test
Please make sure there is no real fire danger when using mute function. If non‐emergency smoke(e.g. Steam) causes
nuisance alarms, please do not stop alarm by block smoke detector or in other forms. You could press the mute/test button
to stop alarm temporarily.(Ten minutes later, the smoke detector will be back to normal working condition)
Press and release the test button to test the alarm. The alarm will sound loud short beeps. It means the smoke detector can
work normally. The alarm may stop sounding once releasing the test button. It is suggested to test the smoke alarm at least
one time every week. Do not use an open flame to test this smoke alarm.
Flat ceiling mounting
We know smoke rises up to ceiling, then will lateral spread, so the best location of an alarm is usually the centre of ceiling. Do
not install smoke detector in the dead air area(as shown in the below figure), besides keep at least 30cm distance from lights
or other decorations. If hall is longer than 12 meters, please install at least 2 smoke alarms.
