First find the suitable place to fix the bracket on
the wall, and then plug the detector into the
bracket. Please see figure 1.
7. INSTALLATION INSTRUCTIONS
The Gas detector is intended to detect leakage of
natural gas, town gas and bottled gas and carbon
monoxide . It is intended for installation in the home,
small commercial properties, and recreational
vehicles (see Figure 3).
Installation shall only be undertaken by
technicians holding a certificate issued by an
authorized distributor.
For detecting natural gas (lighter than air), the
detector should be installed within 30
centimeters below the ceiling and 50cm above
the oven and the maximum distance away from
the furnace or gas appliances is 4 meters.
For detecting LPG (heavier than air), the alarm
should be installed within 30 centimeters above
the floor and the maximum distance away from
the furnace or gas appliances is 4 meters.
The detector should not be located close to any
obstacles preventing natural air circulation. It
should also not be located in a draft or close to a
cooker (cooking smells and other fumes can
have a bad influence on gas detection).

FIGURE 3 WHERE TO INSTALLATION
If your bedroom hallway is longer than 40 feet, install a CO
Alarm at BOTH ends of the hallway.
In a Single-level Home:
z Install at least one CO Alarm near or within each
separate sleeping area.
z For added protection, install an additional CO Alarm at
least 20 feet (6 meters) away from the furnace or fuel
burning heat source.
In a Multi-level Home:
z Install at least one CO Alarm near or within each
separate sleeping area.
z For added protection, install at least one CO Alarm on
each level of the home. If you have a basement, install
that CO Alarm at the top of the basement stairs.
z For added protection, install an additional CO Alarm at
least 20 feet (6 meters) away from the furnace or fuel
burning heat source.
! WARNING!
This unit does not work without power. Choose an
outlet where it can’t be accidentally unplugged or
switched off by children. Keep small children away
from the unit. Teach them not to play with it or
unplug it. Explain what the alarms mean.
WHERE CO ALARMS SHOULD NOT BE INSTALLED
DO NOT LOCATE THIS CO ALARM:
z In garages, kitchens, furnace rooms, or in any
extremely dusty, dirty or greasy areas.
z Closer than 20 feet from a furnace or other fuel burning
heat source, or fuel burning appliances like a water
heater.
z Within 5 feet of any cooking appliance.
z In extremely humid areas. This alarm should be at least
10 feet from a bath or shower, sauna, humidifier,
vaporizer, dishwasher, laundry room, utility room or
other source of high humidity.
z In areas where temperature is colder than 40°F (4°C) or
hotter than 100°F (38°C). These areas include
unconditioned crawl spaces, unfinished attics,
uninsulated or poorly insulated ceilings, porches, and
garages.
z In turbulent air, like near ceiling fans, heat vents, air
conditioners, fresh air returns, or open windows.
Blowing air may prevent CO from reaching the sensors.
z In direct sunlight.
z In outlets covered by curtains or other obstruction.
! WARNING!
This CO Alarm is designed for use inside a
single-family home or apartment. It is not meant to
be used in common lobbies, hallways, or
basements of multi-family buildings unless working
CO Alarms are also installed in each family living
unit. CO Alarms in common areas may not be heard
from inside individual family living units.
! WARNING!
This CO Alarm alone is not a suitable substitute for
complete detection systems in places which house
many people, like hotels or dormitories, unless a
CO Alarm is also placed in each unit.
! WARNING!
DO NOT use this CO Alarm in warehouses,
industrial or commercial buildings, special-purpose
non-residential buildings, RVs, boats, or airplanes.
This CO Alarm is specifically designed for
residential use, and may not provide adequate
protection in non-residential applications.
8. OPERATION AND TESTING
Check and test the gas detector after installation. It
should be tested weekly and check after
re-occupation following a holiday.
z Power Up: After turn on the power, the Green
Power LED is on, buzzer beep once and the
Yellow LED flashes. The unit would take
approximately 3 minutes to warm up. After
warm up, the Yellow LED stop flash and the
buzzer beep twice. In the warm up time, the unit
doesn’t response to any operation until end of
the warm up period. It’s forbidden to test
detector during the warm up period.
z Normal: When the unit is in normal status, the
Green Power LED is on, and Yellow LED is off,
Power LED flashes every 3 seconds.
z Fault: When the sensor is in the fault status, the
sensor Yellow LED is on, the buzzer beep (0.5s
ON/3s OFF). The unit will restore to normal
status after the fault has been corrected.
z Alarm: While detecting the gas leaking reach
the alarm level, the sensor Red Alarm LED
would turn on and the buzzer sound. while the
unit’s will output relay contacts output(relay
output module), or output signal for electric
valve or electric hand. (See Figure2).
z Test: In the normal status, Press the test button
and the unit should sound and the all LED light,
no signals output. To ensure the gas detector is
working, you should test it weekly.
z Silence: In the alarm status, press Test button,
the unit enter the silence status, the sound
silenced and the red LED flashes quickly, about
4 minutes late, the unit exit the silence status.
Press test button again to exit the silence
status.
z Reset: In the alarm status, press the Test button
down and hold above 5 seconds, the unit would
restore to normal status
9. TESTING AND MAINTENANCE
WEEKLY TESTING
Push and hold the Test button on the cover until a loud alarm
sounds. The alarm sequence should last for 5-6 seconds. If
the Detector ever fails to test properly, replace it
immediately.
REGULAR MAINTENANCE
To keep the Detector in good working order:
z Test it every week using the Test button.
z Vacuum the detector cover at least twice a year, using
the soft brush. Test the detector again after vacuuming.
10. GAS SAFETY GUIDE
z If you hear the gas alarm sound or suspect that
there is a gas leakage. You should open all
windows and doors to allow the gas to disperse.
z Don’t switch on lighting, press door bell,
exhausting fan or any kind of electrical
appliance to avoid explosion. Check all the gas
appliances. Extinguish any naked flames and
