Technical Parameters:

Note: When installing, please open the back cover. Tear off the plastic cover of the battery, then install the battery and it can be used normally.

A.Power-up prompt  (It indicates power-up.)

B.CO concentration (The LCD display shows CO concentration in PPM.)

When CO concentration is less than 10 PPM, it shows 0 PPM.

When CO concentration is more than 550 PPM, it shows “Hco”

When CO concentration is more than 550 PPM, it is very dangerous.

C.Testing operation  (It indicates manual testing is in progress.)

D.Fault warning (It indicates fault warning.)

E.End-of-life warning(It indicates end of unit life, and the product needs to be replaced.)

F.Program code error warning(It indicates an error in the program code.)

Power-up prompt

When batteries are installed and the detector is powered up, power-up prompt will be given. It indicates that the power supply is normally connected, and the indicator lights and buzzer are working normally.

The LCD display shows ”EN”.

Normal operation

The detector will enter normal operation within 20 to 30 seconds after power-up. The Power indicator flashes every 45 seconds. When there is CO in the air, the Power indicator flashed every 30 seconds. The Fault indicator and Alarm indicator are off.

Alarm condition

The alarm won’t stop until CO concentration is lower than 40PPM. Put the detector in clean air, the alarm will terminate automatically in 6 minutes, or you can quit alarm condition by pressing and holding the TEST button for 1 to 3 seconds.

Alarm silence

When the detector is in alarm condition and the CO concentration is less than 200 PPM, press the TEST button and it will enter alarm silence condition. Alarm silence condition is the same as alarm condition except the buzzer doesn’t beep temporarily. The Alarm indicator still flashes. Alarm silence condition lasts less than 10 minutes. Press the TEST button in alarm silence condition, and it will recover alarm condition immediately.

Low CO concentration warning

When CO concentration is greater than 30PPM for a duration of more than 60 minutes, or when CO concentration is greater than 40PPM for a duration of more than 40 minutes, low CO concentration warning will be made.

Low CO concentration warning won’t stop until CO concentration is less than 25 PPM.

Testing

Press the TEST button, and the Power, Fault and Alarm indicators will flash once at the same time. If the detector is working properly, then one cycle of alarm will be made. If there is malfunction, then fault warning will be made.

When testing, the LCD display shows ”- – -”.

Steps of alarm installation

a) Take out the mounting plate and line it with the wall in the position that you have chosen for installation. Mark the holes with a pencil dot. With the aid of your wall punch and hammer, make two holes (6mm diameter, 40mm depth) on the marked spots.

b) Insert the two plastic anchors into the holes. Secure the mounting plate to the wall upwards by screwing.

c) After making sure the mounting plate is secured to the wall, power on the detector and test. If the test result is normal, then slide the alarm down over the mounting plate until it snaps into place.
