First, the features using patented gas sensor, no passivation, lower power consumption and longer life; unique design, can sense natural gas, methane gas, liquefied petroleum gas; MCU intelligent control, self-test, to prevent false positives and eliminate omission, stable and reliable; can be used alone or networked with alarm systems, sound and light alarm, automatic reset; Flexible Installation: Wall / Ceiling; energized within one minute without warning; Second, the technical indicators induction gas: natural gas, liquefied petroleum gas, methane gas, alarm levels: natural gas: 0.1-0.3% methane gas: LPG 0.1-0.5%: 0.1-0.5% Working power: 9-15VDC 220V Working environment: Temperature: -10 -50 ℃ Relative humidity: ≤97% Working current: 10 ~ 20mA plastic shell fire alarm sounds great, imported chips output frequency: 315MHz Alarm volume: ≥95db Response time: ≤20 seconds gas concentrations and prolonged Dimensions: 80X75X29 ( mm) Third, the installation first determine the proportion of combustible gas and air, and then the SG-278 household gas leak alarm is fixed in a suitable location away from the gas source within a radius of 1.5M installation. Methane gas is lighter than air ----, ---- floating aloft natural gas is lighter than air, floating aloft ---- liquefied petroleum gas is heavier than air and deposited on the lower connect after power-up, alarm "beep" sound, while the power light (red light) blinks to indicate normal operation has entered, when the sensor and intelligent judgment after a gas leak, issue a "beep - beep" alarm sound News) flashes, while the output alarm signal, After exclusion of alarm, the alarm automatically resume normal operation. If the sensor fails, the alarm is issued "Di -." Long song, fault lamp (── long bright red, while the output alarm signal, troubleshooting, automatically resume normal operation state four, testing and maintenance every once detected Methods: Under normal operating conditions the alarm continued for about 5 seconds to vent injected into combustible gases (usually with a lighter to no ignition) is about 5-8 seconds of sound and light alarm, indicating normal function; weekly detection method : Press the alarm test / reset button, then release the "beep" sound, indicating that the performance of normal (NOTE: This will cause the alarm was just energized, four minutes into the normal working condition); often with a vacuum cleaner or other methods Clear the air intake sensor dust and oil V. Note Do not install outdoors; do not install to the air inlet, fan, door and other places large amount of wind flow; do not install exceed -10 ~ 50 ℃ place; do not install beyond a very damp places; Do not install the alarm object and gas equipment to isolate areas; avoid extensive use of solid hair spray, pesticides, paint adhesives, thinners alcohol near the alarm; In the event of failure, do not disassemble repair six alarms, alarm handling when the ambient air combustible gas concentration reaches or exceeds the alarm set concentration, the alarm will continue to enter the alarm state, then you should: Immediately turn off the gas pipeline bolt; Now open the windows so that the indoor air circulation; extinguish all ignition sources and can produce sparks all items (such as lighters, strike a match, etc.); avoiding all kinds of electrical switch; check gas leak causes, and promptly notify the relevant departments and related professionals.
