It can detect the indoor concentration of carbon monoxide concentrations above the warning value alarm. Technical parameters Features Detection principle: the gas sensor probe 1, using imported high-performance sensor operating voltage: 12VDC 24VDC 220VAC 2, sensor modeling, easy to replace, maintenance, calibration power: 3W 3, various types of gas sensors are used interchangeably Environment: temperature -10-50 ℃ 4, microprocessor-controlled, MP thin film technology, low failure rate response time: ≤30S automatic recovery 5, live sound, light alarm Sample: natural diffusion 6, ventilation or air source close linkage Alarm: audible and visual alarm Ordering Guide Alarm volume: ≥85dB Machine Weight: 260g [Standard accessories] alarm, screws, manual Dimensions: 144 * 105 * 53mm [Optional accessories] exhaust fan system Operating Instructions ① AC lamp : green light, the power is lit. ② Alarm LED: red, flashing alarm, stop the alarm goes off. ③ fault light: yellow light, when a fault occurs only flashing yellow light ④ power, green light flashes, after 30 seconds the alarm enters normal working condition, that is, 30 seconds can be the key test and test alarm with the body. ⑤ normal state, the case of carbon monoxide reaches the alarm point ,, alarm LED red light starts flashing, buzzer "B, B, B ..." sound the alarm, but the concentration of carbon monoxide gas detection alarm point drops to below, the alarm will gradually stop. ⑥ If the increase in the United fan function, when the alarm alarm, the alarm will automatically turn on the exhaust fan to remove harmful gases. At the same time this multi-function switch can also be manually turned on the exhaust fan, an alarm is energized, the red light will flash, press the test button, the alarm will sound an alarm, indicating that carbon monoxide alarm is powered and the line is working. (Power or replace the battery, the alarm may sound, it will return to normal after a few minutes.) Alarm voltage is low, about 30 seconds will issue a "jack" sound to remind you every power shortage, you replace the battery . How to test the alarm, press the "test" button, the alarm will sound an alarm, the red light flashes, indicating that the alarm is working properly. Installation and initialization alarm installation location: carbon monoxide gas is lighter than air, the alarm should be installed in the ceiling from about 0.3 meters away from the carbon monoxide in the gas source radius of 1.5 m range, and well-ventilated place. Direct smoked soot and other vulnerable position; position the corner, cabinet and other air circulation is not easy: ban the installation location. Prohibit installation time: A: No house renovation and decoration End house fully ventilated less than 5 days. B: build a house or buy new wood furniture, fully ventilated less than 3 days.
