MANUAL FOR INDEPENDENT PHOTOELECTRIC
SMOKE DETECTOR
Ⅰ.
Product profile
The photoelectric smoke detector (hereinafter referred to as the alarm) is an independent type alarm
that can detect the smoke generated during a fire and issue an alarm signal in time.
The alarm device is made of photoelectric smoke-sensing device, flame-retardant engineering material
shell and excellent production process. It has beautiful appearance and stable work.
Using 3.6V lithium sub-battery for power supply, low power consumption, one battery life can be more
than 5 years (different use places and alarms, actual use life time may be different), with
environmental self-test function and power supply under voltage prompt function.

Installation and use
1, Product installation instructions:
When you get the product, first confirm that the package is intact and then open the package.
1.1, Open the battery compartment
After getting the alarm, first observe, find the opening direction of the alarm, grab the alarm with both
hands, press the battery cover with your thumb, and push forward. As shown below:
1.2, Install the battery
Install the battery after opening the battery cover. (Note that the battery is not installed correctly. If the
battery is installed, the alarm will not work properly. There is an anti-battery reverse device inside the
battery compartment. The battery reverse installation will not cause the alarm to be damaged. But it
will cause the alarm to not work properly.)After the test equipment has no problems and is working
properly, install the alarm battery cover.
1.3 After the alarm battery is installed, the test is free of any problems and the battery cover is closed.
As shown in Figure 1 :
1.4. Open the mounting base: the bottom of the alarm is a separate mounting base. Grasp the base
with your hand and turn it counterclockwise according to the label. As shown in Figure 2, 3:
