Please read the installation and use before installing and using the product


The instructions. Please take good care of this instruction manual


So that you can check it at any time in the future.


Summary of a.


Internet-connected photoelectric smoke fire detector (hereinafter referred to as the "network")


Infrared photoelectric sensor designed with special structure


Machine, reliable performance of MCU, and SMT SMT chip processing workers


Technical production, with high sensitivity, stability and reliability, low power consumption,


Beautiful and durable, easy to use and other features.


The product is not suitable for use in the following environments:


There is smoke retention under normal circumstances.


There are large dust, water fog, steam, oil fog pollution, decay


The environment that corrodes the gas.


The relative humidity is greater than 97% of the environment.


Environment with ventilation speed greater than 5m/ s.


Ii. Working principle


The detector adopts photoelectric sensing designed with special structure


Combined with MCU with reliable performance, it can effectively detect fire


Smoke generated during or after smoldering in the early stage of a disaster. when


Smoke enters the detector, scattering the light source and receiving the light


The element senses the intensity of light, the intensity of light received and the smoke


The concentration has a certain linear relationship with the field parameters of the detector


Continuously collect, analyze and judge when confirming field data


When the light intensity of the relay reaches the predetermined threshold, the relay transmission is started


And out the other.


When the smoke in the environment returns to normal,


The detector automatically returns to normal working state.


Self-test: under normal circumstances, press the self-test test button.


The detector carries out its own internal function test and relay transmission


And out the other.


Note: when the detector alarms, the output relay is not available


Source contact, contact capacity 11/24vdc,


Iii. Technical features


Power supply: DC9V ~ DC46V


Current: the static current is less than or equal to 300uA


The alarm current is no more than 45mA


Working temperature: - 20 ℃ ~ + 120 ℃


Relative humidity: 97% RH or less (40 ℃ plus or minus 2 ℃)


Output form: relay contact factory normally closed, contact


Capacity of 1 a / 24 VDC,


.


Smoke sensitivity: 0.15 ~ 0.3db /m

V. installation and debugging


(1) according to the installation size, punch four holes in the wall


Fixed hole of 6mm;


(2) insert expansion plug pipe into the fixed hole and screw it in


Self-tapping screw, about 2-3mm clearance is reserved;


(3) the detector should first connect the power line and signal line


The residual signal may be cut off according to actual requirements;


Connection mode


The red line is DC plus


Black wire -DC-


Connect dc9-dc46v power supply;


White line NC-- -- normally closed contact of relay signal;


White line COM-- relay signal common end contact


Vi. Instructions for use


Normal state: 2HZ relay is started up for 5 times


Close/open, the detector enters the working state.


Self-check status: the detector should be self-checked regularly when pressed


When pressing the button, the output contact of the detector relay is closed;


When the key is released, the detector will automatically return to normal operation


As a state.


Vii. Fault analysis and troubleshooting




Alarm no output: check whether the wiring is bad


Frequent false alarm: excessive accumulation of dust in the sensor, use suction


Dust collector cleans maze (external black plastic part)


Maintenance eight.


In the process of use, if you encounter a failure to use, please do


Contact the supplier immediately, do not disassemble and repair without permission,


In case of accident.


If not used for a long time, the detector must be removed and installed


Put into the box and store in a dry and ventilated place.


Transportation and storage


According to GB/ t15464-1995 "instrument packing pass"


Transport and storage in accordance with the technical conditions.


The original packaging must be maintained during transportation and storage


And seal integrity, and ensure that the product is not subjected to violent impact


Blow.


Drastic changes in ambient temperature should be avoided.


The stacking height shall not exceed 6 layers after unpacking


The stack height of single pieces shall not exceed 5 layers.
