					                                  GAS DETECTOR
                                 DG220R = JIC-680

Important basic data
This detector Is UL listed and meets UL standard 2034 (UL 2034 : Single Station Carbon Monoxide detectors)
It plugs into an electrical power outlet of 220Vac~240Vac 50~60Hz.
Warning : This unit will not operate during power failure. Do not install in a wall switch controlled outlet.

This carbon monoxide gas from any source of combustion. It is not designed to detect smoke, fire or any other

Note : This CO detector is a single station detector. Do not link this detector to any other detectors.
This device may not alarm at low carbon monoxide levels. The Occupational Safety and Health Administration
(OSHA) has established the continuous exposure to levels of 50PPM (P arts per Million), should not be
exceeded in an 8 hour period. This CO detector has not been investigated for carbon monoxide detection below
100PPM. Individuals with medical problem may consider using detection devices with lower Cohb alarming

Installation instructions

 Correct mounting position : Mount CO detector on the wall. Mount at least 6 inches, measured vertically
  from the highest point of the ceiling. At least 5 feet above the floor. This CO detector id designed for use
  inside a single family home, flat or garage.
 Do not install this CO detector in the following areas :
       Where the temperature is usually below 4,4°C or exceeds 49°C. Humidity over 95%
       Within 1.5m of any cooking appliance
       In unventilated rooms where paint or thinner or contaminant such as cleaning supplies may be stored
       Boats or RVs. Multiple family bldg., unless there is a detector in each family unit
       In a hazardous location as defined in the National Electrical Code

Caution : This CO detector will only indicate the presence of carbon monoxide at the sensor. Carbon monoxide
may be present in other areas.

What to do if alarm sounds
Warning : Carbon monoxide cannot be seen, felt, tasted or smelled but it can be fatal. It is a “silent killer”.
If alarm sounds (this indicates the presence of CO which can be fatal) (continuous pulsating alarm and alarm
red light is on) / (green light would also be on).

 If anyone has a headache or an upset stomach, call the Fire department and immediately move to a location
  which has fresh air. Do a head count to check that all persons are accounted for. Do not re-enter premises
  until it has been aired out and the problem corrected!
 If no one exhibits symptoms of discomfort associated with CO poisoning, simply :
       Operate the “RESET” button.
       Turn off appliances, vehicle or other sources of combustion at once (furnace, water heater, wood,
           coal, kerosene) burning stove r heater, RV, automobile) or the like.
       Immediately get fresh air into premises or vehicle.
       Fix the CO source problem before restarting appliances or vehicle

If alarm sounds, press TEST/RESET button and the alarm will turn off. If CO is higher than 100PPM, the alarm
will again turn on after 2.5 minutes. Now, you know that it is not a false alarm.

Testing instructions

 If trouble alarm sounds every 30 seconds an internal failure is indicated (green light would also be flashing).
   Unplug the detector and send it back to the seller.

 Green light must always be on. If only green light is on, then this indicates that the detector is receiving
   power and everything is functioning correctly. If green light goes off, first, check power source. If power
   source is correct then the Co detector has an internal system failure and must be repaired or replaced.

 Test instructions, frequency and maintenance : press the TEST/RESET button. The CO detector should
   sound an alarm and will continue to sound as long as the button is pushed in. Power (green) light will flash,
   Alarm (Red) light will be on. This indicates that the CO detector is functioning properly. This testing tests
   all CO detector functions, as required by underwriters laboratories. No other method of testing should be
   performed. Do not attempt any maintenance other than cleaning of light covers to assure that they are easily
   visible. Also vacuum detector air vents. This simple testing procedure and maintenance should be done at
   least once a month.


Standard function
Whenever the CO detector detects carbon Monoxide up to 100PPM, the red light and audio alarm sound will
automatically turn on in 25 minutes. When audio alarm sound, in this event you must at once follow the regular
CO alarm procedure. If the CO level reaches 200PPM, the red light and audio alarm sound will automatically
turn on in 12.5 minutes. If the CO level reaches 400PPM, the red light and audio alarm sound will
automatically turn on in 5 minutes.

               CO concentration              Max. exposure time           Alarm will activate at
                      100PPM                        90 minutes                    25 minutes
                      200PPM                        35 minutes                   12.5 minutes
                      400PPM                        15 minutes                     5 minutes

Exhaust fan function
When CO reaches 100PPM then warning sound will turn on in 32.5 minutes and will continue sounding. When
CO reaches 400PPM then warning sound will turn on 7.5 minutes and will continue sounding. When CO
reaches 100PPM the alarm circuitry will turn on the exhaust fan in 17.5 minutes. When CO reaches 400PPM
the alarm circuitry will turn on the exhaust fan in 7.5 minutes. When CO reduces to 50PPM the alarm circuitry
will turn off the exhaust fan and warning sound in 5 minutes.

               CO concentration            Max. exposure time          Alarm will activate at
                     100PPM                       90 minutes                  32.5 minutes
                     200PPM                       35 minutes                  32.5 minutes
                     400PPM                       15 minutes                   7.5 minutes

               CO concentration            Max. exposure time          Alarm will activate at
                     100PPM                       90 minutes                  17.5 minutes
                     200PPM                       35 minutes                  17.5 minutes
                     400PPM                       15 minutes                   7.5 minutes

              CO reduces to 50PPM            Relay and alarm will turn off in 5 minutes

Carbon monoxide poisoning
The following symptoms are related to carbon monoxide poisoning and should be discussed with all members
of the household.

Mild exposure : Slight headache, nausea, vomiting, fatigue (often described as “Flu-like symptoms).
Medium exposure : Severe throbbing headache, drowsiness, confusion, fast heart rate.
Extreme exposure : Unconsciousness, convulsions, cardio-respiratory failure, death.

Example : At 100PPM in 90 minutes or at 400PPMin 15 minutes in (curve I), COHb is 10%. Nothing to
happen. But at 100PPM over 180 minutes or at 400PPM over 22 minutes is on (curve H), COHb is 15% and a
slight headache to occur. If at 400PPM over 120 minutes, COHb reaches 45% (curve B), it can be FATAL.
