  • Photoelectric fire smoke detector
This product is photoelectric smoke detector (hereinafter referred to as "detector"), which uses the principle of particulate refraction infrared light in smoke to detect fire. The circuit mainly consists of infrared emission part and receiving part, and emitter tube and receiver tube are placed in optical maze. The optical labyrinth can shield the stray light from the outside, but does not affect the smoke entering. 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. In order to reduce interference and power consumption, the transmitting circuit works in pulse mode, which can improve the service life of the transmitting tube. The product adopts unique structure design and photoelectric signal processing technology. It has the functions of dust-proof, insect-proof, anti-external light interference, etc. The design ensures the stability of the product. This product has a good response to visible smoke caused by slow smoldering or light burning. Suitable for smoke monitoring of indoor environment such as residence, shopping mall, hotel, office building, teaching building, bank, library, computer room and warehouse etc.

Product installation and testing:
1 (independent or wireless) please connect the battery to the battery button, into the battery box in the product, keep the battery power supply, the product into normal working state.
2, connect DC 12V power supply, red positive, black negative, white is common, orange is open, yellow is always closed.
3, turn on the power, the detector directly into the normal monitoring state. The indicator lights flicker every 40 seconds; the lights flicker once a second when alerting.
4. Choose the right position, generally install on the ceiling in the center of the detection space, fix the base in the selected installation position with the mounting screw, clip the detector in, rotate and check whether it is firm.
5. After installation, press test key to test whether the product is working properly, whether the peak-buzzer is buzzing (independent type), whether to transmit wireless signal (wireless type), and whether the relay output is normal (networked type).
6. Smoke can be blown directly into the detector to test the performance of the product. After the smoke disperses, the detector resets to the normal monitoring state. Simple maintenance: * the alarm should be cleaned every 6 months to keep the working efficiency good. Turn off the power supply first, and then use a soft brush to gently sweep the dust. Turn the power on again.

If you find the following problems:
1, press the test key but not sound.
2, smoke test but no sound.
3, the ready lamp no longer stably flashes.

Try the following improvements:
1. Check if the power is working as usual.
2, simply clean it. Please ask the electrician to check thoroughly.

Note:
1, this product should not be installed in extremely cold, extremely hot, very high wind speed and often there is a large amount of smoke and dust environment.
2. The product is tested once a month. In order to ensure the smoke sensitivity of the product, it is necessary to clean the detector surface with a soft brush every six months.
3, (independent or wireless) when the battery voltage is insufficient, the peak ringing will make a short "beep" every 40 seconds. To ensure the detection sensitivity of the detector, please replace the battery in time.
4. If you find that the product is not working properly or damaged, please do not disassemble yourself. You can contact the customer service center or the nearest agency, there will be professional service for you.
5. Photoelectric smoke detectors can reduce the occurrence of disasters, but can not be guaranteed to be foolproof. For your safety, please use this product correctly, at the same time in daily life should be vigilant, strengthen the awareness of safety prevention.
