Project Description

portable CO detector with EN50291 and EN50270 certificate


Model VIP-910P




1.Electrochemistry Carbon Monoxide Sensor.

2.Super bright LED Display.

3.Low power alert.


5.Power saving.



Features :


1.Loud 85 decible alarm.


2.Permanent carbon monoxide sensor.


3.Powered by DC9V batteries.


4.When battery line connect with battery, co alarm be in initialization state, after 90 sec, it will operate normal


5.The alarm sound pattern is four short alarm beeps. The red LED will flash while in alarm mode.


6.One ‘chirp’ every 30 seconds is an indication that the battery is low(need replacement)(green LED still flashes once every 30 seconds).


7.Test/Reset button to test the unit electronics and verifies proper unit operation and reset the unit during CO alarm.


8.Alarm memory feature: If the unit ever alarms, pressing the button, green LED will flashes once every second for one minutes.


8.Green and red LED lights that indicate normal operation and alarm status.


9.The unit will sound ‘chirp’ and red LED flashes once as power up.


10.Power saving feature: The alarm sound pattern is 4 beeps every 5 seconds in the beginning. In 4 minutes, it will change to 4 beeps every minutes to save the battery.


11.In 3 minutes after the batteries installed, the unit start to detect CO.




Green LED: The green LED flashes every 30 seconds to indicate the unit is operating properly.


Red LED: When a dangerous level of carbon monoxide is detected the red LED will flashes and the alarm pattern will sound.


The CARBON MONOXIDE (CO) alarm monitors the air for the presence of CO. The alarm will sound and be accompanied by the flashing red LED light when there are high levels of CO present.


CAUTION: This alarm will only indicate the presence of monoxide at the sensor. Carbon monoxide gas may present at other area.


Wide Applicability

Applies widely to works, banks, stores, warehouses, offices and homestead  etc.
