⑪Working principle: JYT-CD-SA120INI stand-alone photoelectric smoke detection alarm adopts a photoelectric sensor with special structural design, which can effectively detect the smoke generated in the initial smoldering stage of the fire or after it is generated. When the smoke enters the detector, the light source will scatter, and the light receiving element will feel that the light intensity reaches the predetermined value, the detector will send out a fire alarm signal, the fire confirmation light (red) will flash, and the buzzer will start to alarm.

 

⑫Installation method: Drill two installation holes on the ceiling at a distance of 36mm, and fix the bottom plate of the alarm with expansion plugs and self-tapping screws. Open the upper cover of the alarm, and install the 9V laminated battery in the alarm. Note: If the direction of the battery is reversed, the alarm will not work normally, and the alarm may be damaged. Fasten the upper cover of the alarm, press and hold the self-test button, the indicator light of the alarm flashes quickly and an alarm sounds, indicating that the alarm is working normally. If it is not normal, you should check whether the battery is installed correctly or the voltage is too low (less than 7.5V.

After the alarm is tested, buckle the alarm on the bottom plate and turn it clockwise into place.
