Smoke alarm

BATTERIES /REPLACEMENT
The smoke detector works on one 9V DC battery. Normally the battery will last for at least one year under normal conditions of use. If the battery is empty or
almost empty the smoke detector will indicate this with an audible “beep”. This indicator sounds continually with intervals of 30-40 seconds for at least 30 days.
Replace the battery when this indicator is given. Please use 9V alkalescence DC batteries(type:6LR61) with high quality (Available from most department stores,
DIY shops, electronic supply shops) .Placing the battery is very simple: remove the mounting bracket on the backside and connect the battery.

MOUNTING
Where is the best place to place the smoke detectors?
* at least 1 in each room
* one on each oor
* in the hallway, in the stairway,
* in front of each bedroom door
* in each bedroom (if you sleep with the door shut)
* in the living room
* in the storage room or spaces with electric equipment 

The alarm may not be mounted in:
* a room in which the temperature can reach below 4 and above 40 ℃
* in damp spaces
* just in front of doors or windows and not near a ventilator or radiator.
Do not mount the alarm in a place which is dicult to reach because of the test button, replaceable battery and maintenance. The alarm can be mounted easily.
Fix the base plate using the screws supplied onto the area you have chosen. Pay attention to the following instructions and drawings. Gently tighten the alarm
onto the base plate. Mount the alarm in the centre of the ceiling of the room
