Electrochemical carbon monoxide detectors are specially designed to detect CO gas. CO gas is a colorless, odorless, non-irritating, poisonous gas
that cannot be sensed by the five senses. It is mostly produced in fireplaces, charcoal, and electric
appliances with insufficient oxygen. Heater, water heater combustion environment. Therefore, in order to ensure the safety of home life, it is recommended to
install carbon monoxide alarm detectors in kitchens, bathrooms, bedrooms, living rooms, garages and other places where air is not circulated for a long time. This product is powered by a DC 9V battery. When the detector alarms, it emits a >80d B alarm sound and the red alarm light flashes at the same time. During normal operation, the green indicator light flashes once every 60 seconds. The detector has low voltage alarm function and button test function. The detector adopts low-power consumption technology, and the theoretical battery needs to be replaced once a year.

Battery type: DC9V

Battery Life: 1 Year

Working Temprature: -10 to +50

Relative Humadity: 10% to 90% no condensation

Alarm sound: 80dB (at 1 Meter)

Green Light: Normal Monitoring (interval 60s)

Red Light: Alarm

Concentration: 150PPM Alarm

In normal working condition, press the test button and all Light up once, then display the current gas concentration and then turn off the screen. (It is recommended to do a test once a week to ensure the normal operation of the detector.) "Beep once, and display "888ppm" >Avoid installing the following positions
1. Places close to doorways, windows, fans, etc. will affect the sensitivity of the detector because the air circulates quickly in these places.

2. Do not install in high-humidity locations, such as next to the bathroom nozzle, on the top floor or where the temperature is 50°C or below minus 10°C.

3. Simple maintenance: The alarm needs to be cleaned once every 6 months to ensure good working efficiency. Remove the battery first, and then use a soft brush can easily pick up the dust, and then install the battery

 Installation
Select a suitable installation area, mark two holes on the ceiling or wall according to the holes for the brackets, and drill two sub-holes in the two holes. Insert two plastic expansion
tubes into the two holes, then press the back of the mounting plate against the wall, insert and tighten the mounting screws until the mounting bracket is completely secure. This detector is a closed device and is not allowed to be disassembled without permission. Please correctly install the battery into the battery slot of the machine, pay attention to the positive and negative plates, put the back of the detector against the installation position and turn the mouth clockwise, and confirm that the mounting bracket is screwed into place.
