How does Co Detector work?
Carbon monoxide is a gas which is colorless, odorless, tasteless, and highly toxic. Carbon
monoxide is a leading cause of poisoning death and poisoning related injury worldwide.
This Carbon monoxide detector designed to save human life from poisoning. It used
Electrochemical Sensing Technology to sense the Co concentration levels and to provide alarm
indications to user to alter from difficult situations. Co Detector is a low power battery operated
device which provides long life operation to human safety
There are following indications to user:
1. Idle Condition
2. Alarm Condition
3. Self Test
4. End of Battery Life
Ideal Condition:
Ideal condition is nothing but enabling the system for alerting the user against
emergencies. In this condition the Co Detector scan the surrounding environment through
Co Sensor. The GREEN LED blink every minute to show that system is power ON.
Alarm Condition:
Alarm condition is nothing but alerting the user against emergencies when Co Gas
concentration occurs above dangerous level. Once the system is In Alarm condition, then
Co Detector will indicate Alarm condition, it will flashes the RED LED and ON internal
buzzer up-to 30 minute.
Using “Test Key”user can stop the buzzer

The above chart shows different operational modes of CO detector with their working function.
The Co Detector designed according to UL3024 standard and alarm conditions provided according
to %COHB in human body i.e Carboxyhaemoglobin (COHb).
The CO detector detects the concentration of Co gas according to CoHbt
(Carboxyhaemoglobin) level for human body.
Test Key Operations:
1. During Idle condition if the test key is pressed the buzzer will beep and leds will blink.
2. During Alert condition if the test key is pressed the CO detector will go out of alert
condition and will get reset.
