1. Principle of photoelectric smoke detection: infrared scattering technology, making "real smoke" nowhere to hide

This detector adoptsphotoelectric smoke detectiontechnology, and its core principle is based onInfrared Scattering- The infrared emitting tube inside the device continuously emits a beam of light, and the optical maze (darkroom) effectively shields external stray light interference-. When smoke particles enter the maze, the light beam is scattered by the smoke particles onto the receiving sensor. The higher the smoke concentration, the stronger the scattered light signal-. When the concentration reaches the alarm threshold, the detector immediately triggers an alarm, and the indicator light changes from flashing to constantly on-.

. Sensitivity is 0.5db/m (± 0.1db/m). What does this value mean? It represents the device's extremely high ability to capture low concentration smoke - whether it is early smoldering caused by wire short circuits or trace smoke produced by furniture smoldering, it can be accurately identified-.

. What benefits does it have for you?No longer have to worry about 'false reports and false reports'. Optoelectronic technology is particularly sensitive to smoldering fires, such as wire short circuits and furniture smoldering-Especially suitable for places with high electrical fire hazards such as computer rooms, warehouses, hotels, etc-One detector can cover it60-80 square metersThe protected area-From small living rooms to medium-sized warehouses, one unit can handle everything.

2, Relay output · adjustable normally open/normally closed: flexible adaptation, compatible with all systems

How to operate?The physical product provides a red two digit toggle switch - when turned to the "NO" direction, it is normally open, and when turned to the "2" direction, it is normally closed-If you receive the jumper cap version, the C-B short circuit is normally open and the B-A short circuit is normally closed-. (Note: The actual product is either a dial code or a jumper cap. Please refer to the latest product manual.)

What benefits does it have for you?Whether you are connected to a fire automatic alarm system, building intercom system, or anti-theft alarm host, the normally open/normally closed adjustable feature of the relay output ensures perfect compatibility-No need to purchase additional conversion modules to match the system anymore, one detector can handle all scenarios.

III. Dual Reset Mode · Automatic/Power Off Optional: on-demand configuration, worry free and effortless

How to restore the detector after the fire alarm is lifted? This product providesTwo reset methodsSimilarly, flexible configuration can be achieved through dip switches or jumper caps

• Automatic Reset: After smoke is eliminated, the detector automatically returns to normal working state without any manual intervention.

• Power off reset: The detector will only be restored when the power is cut off and then reconnected-.

How to operate? When the dip switch is turned to the "NO" direction, it is a power-off reset, and when turned to the "1" direction, it is an automatic resetTurn the dip switch to the "NO" direction for power-off reset, and turn it to the "1" direction for automatic reset-. Jumper cap version: C-B short circuit for power-off reset, B-A short circuit for automatic reset-.

What are the benefits for you? If you are a data center or warehouse manager, it is recommended to chooseIf you are a data center or warehouse manager, it is recommended to chooseAutomatic Reset- After the smoke dissipates, the equipment will automatically recover without the need for on-site personnel, saving time and effort. If you are a fire protection system integrator and need to manually confirm the fire situation before resetting, thepower-off resetmode can ensure that every alarm is manually verified, eliminating security vulnerabilities.

Fourth, triple anti-interference design: dustproof, insect proof, metal shielding, rejecting false alarms

False alarms are the "number one enemy" of smoke detectors. This product completely solves this problem from three dimensions:

① Dust and insect prevention: The equipment is equipped with a high-density dust net, which effectively blocks large particles of dust and fluff from entering the detector interior; Insect proof design prevents insects from accidentally entering the maze and causing accidental contact-. . It does not require frequent cleaning and the equipment maintains high sensitivity for a long time.

② Anti white light interference: The optical maze structure effectively shields external stray light (including sunlight, lights, etc.), ensuring that the alarm will only be triggered when smoke particles enter-. Even in strong light environments, the detector still only recognizes "smoke" and not "light".

③ Metal shielding against radio frequency interferenceBuilt in metal shielding cover, with anti RF interference capability of up to10MHz-1GHz, 20V/m-Radio frequency sources such as mobile phone signals, walkie talkies, and wireless devices will not have any impact on the detector.You no longer have to worry about the awkward situation of the walkie talkie ringing and the detector screaming.

User Witness

"We used to use traditional smoke detectors, which were constantly reporting false alarms, and we were all numb. After replacing this two-wire photodetector, there hasn't been a single false alarm in over six months. The most crucial thing is that after connecting to HA, the alarm is directly pushed to my phone, and I can also keep track of the warehouse security situation in real time even when traveling. Highly recommended! ”

- Mr. Wang, the warehouse manager of an e-commerce company in Guangzhou (after using it for 3 months, the false alarm rate has decreased by 95%)

"The computer room has high requirements for electromagnetic environment, and several detectors I have tried before have been interfered with by walkie talkie signals and reported randomly. This metal shielded detector has not experienced a single false alarm since installation. Sensitivity of 0.5db/m, even slight overheating of the server power module can be detected in advance. ”

- Li Gong, an operations engineer at a data center in Shenzhen (deployed 26 units, covering a 2000 square meter data center)

"As an HA player, the biggest fear is that the equipment will 'shut down' - it can only trigger local alarms and cannot be linked. This detector natively supports ESPHome, four step distribution network, and automatic detection, which is simply not too exciting. I have now set the alarm to automatically turn on the exhaust fan, mobile phone push, and the living room light flashing, providing a strong sense of security. ”
