Installation Instruction

1. Press the test button and hear the alarm sound and flashing red light to confirm the normal

operation of the alarm sounder, and test it at least once per month.

2. The dirt on the surface of the residential fire alarm sounder can be wiped with a wrung wet cloth,

but you should be careful that water drops cannot fall into the residential fire alarm sounder, and

the battery should be removed before wiping.

3. When dust or cotton wool covers it, it can be removed by vacuum cleaner to keep the residential

fire alarm sounder in the best condition. Please remove the battery in advance when cleaning.

4. When the supply mains are cut off, if the alarm sounder fails to work normally (the green light

flashes every 5 seconds), please confirm the battery status. If the battery is different, please

replace the battery immediately.
