P56402 CO Alarm

Warning device (alarm) for monitoring the concentration of the poisonous gas carbon monoxide (CO)
This manual contains important safety information regarding the installation and operation of the warning device. Read the manual carefully and store it in a safe place for future use or for when the device is passed on to another user.

Warning
The installation of a warning device (alarm) for monitoring CO concentration is not a substitute for correct installation, use and maintenance of fuel- burning devices, including proper ventilation and exhaust systems. This warning device for monitoring CO concentration is designed for protecting persons against the acute effects of short-term exposure to carbon monoxide, but cannot fully protect persons with particular health conditions. When in doubt, consult your doctor. Long-term exposure to low concentrations of CO (>10 ppm) can cause chronic effects. When in doubt, consult your doctor.
The device is only used to detect carbon monoxide (CO), not any other gases. If you are unsure what caused the alarm to go off, always assume the alarm was triggered by dangerous levels of carbon monoxide and evacuate the inhabitants.

What Is Carbon Monoxide (CO)
Carbon monoxide (CO) is an odourless, invisible, highly poisonous gas. It is generated through incomplete combustion of fuels, such as wood, wooden coal, coal, fuel oil, paraffin, gasoline, natural gas, propane, butane, etc., and from cigarette smoke. A dangerous concentration of CO can form if the fuel- burning device is faulty or not properly
maintained, if the fuel is blocked or the room insufficiently ventilated. The seriousness of poisoning from CO inhalation depends on the concentration (listed as number of
particles per million, ppm) and the duration of exposure.

unconsciousness after 2 hours
1 000 ppm| Dangerous concentration — unconsciousness after 1 hour
1 600 ppm| Nausea, strong headaches and dizziness after 20 minutes
3 200 ppm| Nausea, strong headaches and dizziness after 5-10 minutes, unconsciousness after 30 minutes
6 400 ppm| Nausea, strong headaches and dizziness after 1-2 minutes, unconsciousness after 10 —15 minutes
12 800 ppm| Instant unconsciousness. risk of death after 1-2 minutes

All persons residing on the premises should be made aware of the symptoms of CO poisoning!
The device for monitoring CO concentration activates the alarm if it detects a certain concentration of CO for a certain duration:

Installation

The installation must be performed by a qualified person. Ideally, the warning device should be located in every room with a fuel-burning device. It is strongly recommended to also install warning devices in bedrooms and rooms where you spend a lot of time.
If the warning device is installed in the same room as the fuel-burning device:

• Place the warning device in the vicinity of the ceiling and above the level of the top edge of windows and doors.
• When installing onto the ceiling, the warning device must be located at least 30 cm away from walls.

When installing onto a wall, the warning device must be located at least 15 cm from the ceiling and 180 cm from the floor.
Do not install the warning device in rooms with vaulted ceilings, gable roof etc.
Do not install the warning device in the vicinity of ventilation openings or windows/doors that lead outside.
Do not install the warning device behind curtains/furniture; doing so would decrease the ability of the device to correctly detect the CO level.
Do not install the warning device in an area with temperature lower than -10 °C or higher than 40 °C.
If possible, install the warning device approximately at eye level for ease of checking the LED indicators.
If you are only installing one warning device, place it in the vicinity of the bedroom (not in the basement etc.).
Make sure that you can hear all the installed warning devices from the room where you sleep.
The warning device must be located at a distance of 1 m to 3 m horizontally from the nearest edge of a potential CO source.
The ventilation openings of the warning device must not be covered up.
Do not spray aerosol agents in the vicinity or onto the warning device.
Do not paint the warning device.
If the warning device is located in a room without a fuel-burning device, it must be located in the vicinity of the breathing area of the persons residing in the room. In open-plan rooms where people both sleep and spend their time, such as one-room flats, caravans or boats, the device must be located as far away as possible from cookers while also being in the vicinity of the space reserved for sleeping.

Location meeting the requirements set by NFPA (US National Fire Protection Association)
Suggestions for the placement of additional CO alarms in the building

Installing the Device onto a Wall (see Fig. 2)
1 – Openings for hanging onto a wall
Drill two holes (ø 5 mm) into the wall; the distance between the holes should be 52 mm.
Insert the wall plugs provided, then insert the screws provided into the wall plugs.
Insert the screws so that ca. 5 mm protrude out of the wall.
Put batteries into the alarm and test its functioning, see Test Mode.
If the alarm works, close the battery cover and fit the two openings on the battery cover onto the protruding screws.

COMMISSIONING

(see Fig. 3)
Insert batteries (2× 1.5 V AA) into the battery compartment on the back. Use alkaline batteries only; do not use rechargeable 1.2 V batteries (due to their lower voltage).

Warning:
The battery cover cannot be shut unless both batteries are in place! The closing of the battery cover is prevented by two metal bumps underneath the battery compartment. If you wish to mount the device onto a wall, batteries must always be inserted and the battery cover closed.
After inserting batteries, you will hear a beep and all three diodes (POWER, FAULT, ALARM) will flash at the same time. The green POWER LED will flash 1× every 60 seconds after battery insertion; the device is calibrating. After 60 seconds, the GREEN POWER LED will flash 1× every 40 seconds to indicate that the batteries are working.

TEST MODE
You can test the functioning of the alarm whenever needed or after every change of batteries.
Press and hold the TEST/SILENCE button. The alarm will simultaneously beep and flash its RED ALARM LED 4× every 5 seconds.
Release the TEST/SILENCE button; the alarm is ready for use.
Use test mode 1× a week to make sure the alarm is operational.
Note:
The acoustic and optical alarm during testing is only used as indication that the alarm is operational.
It does not mean that the presence of CO has been detected.

FAULT STATE
If the alarm is in a fault state, it is not operational and does not measure CO levels in the room.
The fault state is indicated by simultaneous beeping/flashing of the YELLOW FAULT LED 2× every 8 seconds.
Immediately replace the batteries.
Perform a function test.
The acoustic signal can be temporarily muted for 9 hours using the TEST/SILENCE button (then the acoustic signal reactivates).
The YELLOW FAULT LED will continue indicating a fault.
If the fault state persists even after batteries have been replaced, contact a service centre.

FLAT BATTERIES
Flat batteries in the alarm are indicated by simultaneous beeping/flashing of the YELLOW FAULT LED 1× every 40 seconds.
The alarm is not operational and does not measure CO levels in the room.
Immediately replace the batteries. Perform a function test.
It is recommended to replace batteries 1× a year as a precaution.
The acoustic signal can be temporarily muted for 9 hours using the TEST/SILENCE button (then the acoustic signal reactivates).
The YELLOW FAULT LED will continue indicating a fault.

END OF SERVICE LIFE
After 10 years since production, the alarm must be replaced and its use must be discontinued.
The production and replacement date are listed on the back on the data plate.
The end of the service life of the device is indicated as follows:
Simultaneous beeping/flashing of the YELLOW FAULT LED 3× every 40 seconds.
The acoustic signal can be temporarily muted for 9 hours using the TEST/SILENCE button (then the acoustic signal reactivates).
The YELLOW FAULT LED will continue indicating a fault.

CO WARNING
If the alarm detects dangerous amounts of CO, an optical and acoustic warning will be activated.
The alarm will simultaneously beep/flash the RED ALARM LED 4× every 5 seconds.
The loudness of the acoustic signal will be below 85 dB for the first 10 seconds, then it increases.
The warning will be active for as long as CO is present, until CO levels drop below the danger level or the alarm is silenced manually.

MANUAL SILENCING OF THE ALARM UPON CO DETECTION
The acoustic signal for the presence of CO can be temporarily silenced 1×.
Press the TEST/SILENCE button to silence the acoustic signal for 10 minutes.
The RED ALARM LED will continue flashing.
Note:
The warning will reactivate within 10 minutes of the pressing of the TEST/SILENCE button as long as the CO level is equal to or above 50 ppm.
The alarm cannot be silenced if the CO level is equal to or above 200 ppm.

WHAT TO DO WHEN CO IS DETECTED IN THE BUILDING
If CO is detected in the building, keep calm and do the following:
Stop using all fuel-burning devices and turn them off if possible.
Silence the alarm by pressing the TEST/RESET button.
Make all persons on the premises aware of the situation!
Open all doors and windows and air the area.
If the alarm persists, leave the premises.
Call 112 and the service organisation for your gas appliance and ask the supplier for aid in finding and eliminating the source of carbon monoxide.
Check that all persons have left the premises!
Leave the doors and windows open until the alarm stops.
Arrange medical attention for all persons suffering from symptoms of carbon monoxide poisoning (headaches, nausea).
Inform the doctors of the suspected carbon monoxide inhalation.
Do not use the fuel-burning appliances until they have been checked by a qualified person.
Note:
There may be other sources of carbon monoxide aside from fuel-burning devices. E.g.: emissions from smouldering fire, large amount of tobacco smoke etc.
Attention:
Some substances may affect the sensitivity of the sensor inside the alarm, such as: methane, propane, isobutene, isopropanol, ethylene, benzole, toluene, ethyl acetate, hydrogen sulphide, alcohol-based agents, paint, solvents, adhesives, hair spray, aftershaves, perfumes and some cleaning agents.
