The photoelectric smoke detector is based on the principle of particulate refraction infrared light in smoke to detect fire. The circuit mainly consists of infrared emission part and receiving part, and the emitter and receiver tube are placed in the optical maze.The optical labyrinth can shield the stray light from the outside, but does not affect the smoke entry. In the smokeless state, the receiver only receives very weak infrared light. When smoke enters, the received light signal is enhanced due to scattering. When the smoke reaches a certain concentration, the detector outputs an alarm signal.
1. Please connect the battery to the battery button and install the battery box in the product to keep the battery powered and the product in normal working condition.
2.Turn on the power, the detector directly enter into the normal monitoring state, the indicator flashes every 40 seconds, alarm state, the indicator lamp flicker once a second.
3. Select the appropriate position, generally installed on the ceiling in the center of the probe space, use the mounting screw to fix the base in the selected installation position, clip the detector in, rotate and check whether it is firm.
4. After installation, press test key to test whether the product is working properly and buzzer is buzzer.
The water curtain nozzle is the main component of the water curtain system. It distributes the pressure moisture into a certain width and thickness of the curtain water curtain to prevent flame penetration, heat absorption and smoke insulation.It is used to continuously spray water to form a water curtain to protect the surface from fire and form a fire separation.It is suitable for large factories, workshops, halls and theaters, stage and doors and windows of buildings and openings,etc., or between adjacent buildings.
Classified according to usage
Water curtain nozzles are classified according to the purpose of use, and can be divided into fire separation nozzles and protective cooling curtains.
- 1. Fire-proof partition water curtain nozzle: refers to a water curtain nozzle that forms a water wall or water curtain through intensive spraying to achieve the spread of fire and heat diffusion.
- 2. Protective cooling water curtain nozzle: refers to the water curtain nozzle that is directly sprayed onto the protected object to achieve the purpose of cooling and cooling.
