installation Instructions
Step 1Installation Guide:
IMPORTANT: THIS ALARM MUST BE MOUNTED ON A WALL INSTALL ONLY AS DETALED!
A. ​Recommended installation Locations:
We recommend the installation of a CO Alarm in the following locations.
For maximum protection we suggest an alarm be installed on each level of a multilevel home including every
bedroom, hallways, finished attics and basements. Put alarm at both ends of bedroom hallway or large room if
hallway or room is more than 30ft.(9.1 m) long. If you have only one alarm, ensure it is placed in the hallway
outside of the main sleeping area, or in the main bedroom. Verify the alarm can be heard in all sleeping areas.
Locate an alarm in every room where someone sleeps with the door closed. The closed door may prevent thealarm from waking the sleeper. Mounting the alarm on the ceiling in the center of the room places it closest to all
points in the room. Ceiling mounting is preferred in ordinary residential Construction. When mounting an alarm on
the ceiling, locate it at a minimum of 4"(10cm) from the side wall (see Diagram A). lf installing the alarm on thewall, at a minimum of 4"(10cm) and a maximum of 12"(30.5cm) below the ceiling (see Diagram below).
B. ​Where Not to install:
Do not install in garages, kitchens, furnace rooms or bathrooms. INSTALL AT LEAST 15 FEET AWAY
FROM ANY FUEL BURNING APPLIANCE.
Do not install within 3ft(0.9m) of the following: The door to a kitchen, or a bathroom that contains a rub or shower,
forced air ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas.
Avoid excessively dusty, dirty or greasy areas. Dust, grease or household chemicals contaminate the alarm'ssensors, causing it to not operate properly.
Place the alarm where drapes or other objects will not block the Sensor. CO must be able to reach the sensors toaccurately detect these conditions. Do not install in peaks of vaulted ceiling, "A frame ceilings or gabled roofs.
Keep out of damp and humid areas.
Install at least one foot away from fluorescent lights, electronic noise may cause nuisance alarms. Extreme
temperatures will affect the sensitivity of the CO Alarm. Do not install in areas where the temperature is colder
than 40 degrees Fahrenheit (4.4 Celsius) or hotter than 100 degrees Fahrenheit (37.8 Celsius). Place away fromdoors and windows that open to the outside.
Step 2
Mounting Instructions:
1. Remove the mounting bracket from the back of the alarm by twisting the alarm.
2. After selecting the proper location for your CO Alarm, drilling two Ø5.0mm holes in the ceiling or wall verticallywith the distance of 60mm and inserting one plastic insert into the holes, then attaching the bracket to the plastic

insert with the arrow down to the ground and screwing tightly two screws in the two inserts.
3. Matching the arrow on the back of the alarm with the arrow on the bracket to snap the alarm on the bracket bytwisting the alarm

Step 3
Testing the Alarm
CAUTION: Due to the loudness (85 decibels) of the alarm, always stand an arms length away from theunit when testing.
The test/reset button has two purposes. It tests the unit's electronics and reset the unit during CO alarm. Afterinstallation, TEST THE UNITSELECTRONICS by pressing the test button for five seconds. A series of beeps willsound. If the unit chirps and red LED flashes once every 30 seconds with green LED not flashing once every 30seconds, that means the unit is malfunctioning. You need to return the unit to our agent for repairing.
If the alarm is sounding, pressing the button will silence the alarm for several minutes. After the duration, if theCO Condition that caused the alert continues, the alarm Will reactivate. The duration spans from 2 minutes to 6minutes. ​The unit needs to be tested weekly!​ if at anytime it does not perform as described, verify power isConnected correctly and that the battery doesn't need replacing. Clean dust and other buildup off the unit. If it still
doesn't operate properly call Our agent.

If the CO level keeps from 70ppm to200ppm, the duration is around 5 minutes. If the CO level keeps over 200ppm, the duration is zero, i.e. the unit
will sound soon. If the CO level keeps below 70ppm, the unit will not reactivate longer.
Alarm Memory Feature
If you leave home for long time and during the period the unit ever alarms, after you return and press the button
for several seconds, green LED will flashes once every seconds and the peak alarm level will indicate on theLCD to alert youthere is one CO alarm occurs. You should check the possible CO Source and to resolve it.
Pressing the button again, the unit Will return to normal Condition or return to normal Condition in one minuteautomatically.

LED indicator Operation
Red LED
Red Led will flash in conjunction with the alarm beep.
Therefore, the red LED will flash during a CO alarm, a low battery mode chirp and a malfunction status.
As you install the battery on the unit, the unit will sound "chirp' to indicate the battery installed properly.

Green LED
Green LED flashes once every 30 seconds to indicate proper operation and it is Out to indicate malfunctioning.
What To Do IF The Alarm Sounds If alarm sounds:
1) Call your emergency services.
2) Immediately move to fresh air - outdoors or by an open door/window. Do a head count to check thatall persons are accounted for. Do not reenter the premises nor move away from the open door/window
until the emergency services responders have arrived, the premises have been aired out, and youralarm remains in its normal Condition.
Never restart the source of a CO problem until it has been fixed. NEVER IGNORE THE ALARM!
The CO sensor sensitivity and setting is:
50ppm, within 60 to 90 minutes;
100ppm, within 10 to 40 minutes;
300ppm, within 3 minutes
This carbon monoxide alarm is designed to detect carbon monoxide gas from ANY source ofcombustion. It is NOT designed to detect any other gas.
Fire departments, most utility companies will perform CO inspections, some may charge for this service.
Battery Replacementlf battery failure is detected the unit will 'chirp' one time. This cycle will occur once every 30 seconds.
