Indoor CO detector - Home CO alarm clock

Description

Description

The CO alarm adopts imported first-line major brand chemical sensors, which have the characteristics of rapid and sensitive response, strong anti-interference ability, long life, high precision, high repeatability and high stability. The carbon monoxide alarm detector is suitable for detecting confined living places: The concentration of carbon monoxide in agricultural greenhouses, production workshops, indoor barbecues, agricultural breeding and other environments.

CO alarm composition:

Carbon monoxide alarm consists of two main parts: sensor and conversion system. CO gas detection sensor alarm based on CO gas detection, can detect the concentration of dangerous gas CO exposed to the environment, clearly read the gas concentration, peak, concentration, alarm level. When the gas concentration exceeds the preset maximum or minimum value, the alarm will send an alarm to the user through audible and visual alarm.

Features:

(1) The factory has been calibrated, without secondary calibration, with good sensitivity, repeatability and accurate measurement;

(2) High definition density display on the LED screen, the reading is clearer;

(3) convenient installation, small volume, convenient installation, does not occupy space;

(4) Low voltage consumption and low power consumption processing chip, long standby time and low voltage automatic prompt, avoid stopping work.

Details:

(1) Loud speaker can be heard by the elderly, CO alarm sound is 80dB< 110 db;

(2) High-precision electrochemical CO sensor module, built-in high-precision electrochemical sensor, through the amplification circuit will gas analog signal output into digital signal;

(3) Sound and light alarm. When the detector detects that the concentration of CO exceeds the alarm value, the red indicator lights up and immediately alarms;

(4) Self-check alarm elimination function. When the CO detector alarms, the user can press the button long to start the self-check, and press the button long to cancel the alarm sound when the alarm is generated;

(5) No. 5 battery power supply, CO alarm uses no. 3 and no. 5 battery power supply, easy to disassemble, does not occupy other sockets.

Installation precautions:

Where to install the detector:
(1) First of all, it is necessary to confirm whether the gas to be detected is lighter than air or heavier than air. Installation location. When the detector alarms, everyone in the indoor environment can hear it;
(2) Gases heavier than air include liquefied petroleum gas, etc., and the detector should be installed 0.3-1.0 meters above the ground and within a radius of 1.5 meters from the gas source;
(3) Gases lighter than air include natural gas, biogas, etc. The detector should be installed 0.3-1.0 meters below the ceiling and within a radius of 1.5 meters from the gas source.

Where can not install the detector:
(1) The CO detector should not be installed too close to the gas stove to prevent the detector from being baked by the stove flame.
(2) It cannot be installed in a place where there is a lot of oily smoke, so as to prevent the oily smoke from blocking the air inlet of the detector and causing poor air intake, thereby affecting the sensor's sensitivity.
(3) It cannot be installed in places with large water vapor flow such as exhaust fans, doors and windows.
(4) Don't install in dusty, dirty or insects.
