Ei208W/Ei208DW Stand-alone carbon monoxide detector MZZ25008
1
Ei208W/Ei208DW stand-alone carbon monoxide detector
The product serves for the detection of CO (carbon monoxide) gas and
early warning to avoid the harmful effects of this gas on human health.
The detector is certificated for use in building interiors, caravans and
boats.
The detector indicates excessive carbon monoxide concentration both
optically with a LED (Ei208DW also shows the concentration data on the
display) and acoustically using a built-in siren.
The detector is powered with an integrated lithium battery which supplies
the detector for its whole service life.

Origin of carbon monoxide and its effects on
the human organism
CO (carbon monoxide) is a very dangerous gas which is poisonous even
in small concentrations. It is generated by imperfect combustion of fossil
fuels (natural gas, petroleum, coal, wood). The gas is colourless, tasteless
and odourless. Therefore, it cannot be detected by the human sense and
there is a great danger of intoxication of the human organism with this gas.
The main carbon monoxide sources:
−incorrectly installed or poorly set fuel-burning appliances (gas, coal,
fuel oils and wood)
−blocked, poorly maintained or damaged chimneys
−combustion engines running in confined spaces
−portable paraffin or gas heaters in confined or badly ventilated rooms

The same concentration of CO may have a different effect on persons
with varying body weight or who are weakened by an illness.
Warning: The CO detector may not prevent the chronic effects of carbon
monoxide exposure, and the apparatus will not fully safeguard individuals at
special risk.
Detector range and location
Ideally, the carbon monoxide detector should be installed in every room
containing a possible source of carbon monoxide (boilers, fireplaces, local
heaters, etc.). It is also recommended to install the carbon monoxide
detector in the rooms where occupants spend considerable amounts of
time and bedrooms where they sleep.
Rooms with possible
sources of carbon
monoxide and level
ceilings. Installation
above the upper
edge of any window
or door. At least 15
cm from the ceiling.
Installation on the
ceiling at least 30 cm
from the walls.
Rooms with possible
sources of carbon
monoxide and sloped
ceilings.
Bedrooms and other
rooms remote from
possible sources of
carbon monoxide.
Installation at the
approximate height of
1 to 2m in the
expected breathing
zone of the
occupants.
1 – unsuitable location; 2 – recommended location
Avoid installing the detector in the following locations:
−in the immediate vicinity of heat sources (keep it at least 1 metre
horizontally from any heat source)
−in an enclosed space (e.g. in a cupboard)
−above a bath, a washbasin or heat sources
−next to a door, a window, an air vent or anywhere where it would be
affected by draught
−in places where free circulation of air is obstructed (e.g. behind curtains
or furniture)
−in places with high levels of dust, humidity or in places where it would
be subjected to water or steam.
−in places with high levels of paint, thinner or solvent fumes or close to
air fresheners
−in places where it could be easily damaged or accidentally knocked or
turned off
Warning: Do not use the detector as a portable device or on an intermittent
basis.
Interfering Substances
−The apparatus should not be exposed to excessive amounts of fumes
from petrol, diesel, solvents, greases, alcohols and organic cleaning
fluids.
−The apparatus may respond to brief exhaust gas emissions e.g. during
initial start-up of an appliance or engine.
−Hydrogen acts as an interferon and may give rise to alarms.
Installing the detector
When installing the detector, abide by the procedures recommended in the
previous paragraphs.
Warning: The Installation of this CO Alarm should not be used as a
substitute for proper installation, use and maintenance of fuel burning
appliances including appropriate ventilation and exhaust systems.
In addition the CO detector must be installed by a competent person
Installation steps:
1) Open the detector by turning it anti-clockwise
2) Attach the base to the selected place using
screws.
3) Insert the detector into the plastic base and
secure it by turning it clockwise
4) Once you have inserted and secured the
detector, it is switched on automatically with a
built-in switch located in the detector body
5) If the detector is OK, all three LEDs will flash
briefly in sequence and all symbols on the
display (Ei208DW) will light up.

6) In order to make the detector resistant to unauthorized removal and
tampering, break off the small pillar on the base as shown in Fig. 4a.
To remove the detector from the ceiling it is now necessary to use a
small screwdriver which has to be inserted between the detector body
and the catch in the base (fig. 4b). The locked detector can further be
secured against rotating with a self-tapping screw as shown in Fig. 4c
Fig.4a Fig.4b Fig. 4c
Alarm signalling
Pre-alarm: when the detector detects over 43 ppm CO, the red ALARM
indicator flashes in accordance with the table. This is usually not a concern
in a shorter time interval, unless the acoustic signal sounds. Such a slightly
increased concentration may come from various sources, e.g. from
cooking, barbecuing or starting a combustion engine. The display shows
the current carbon monoxide level if it exceeds 10 ppm.
When the detector detects a potentially dangerous carbon monoxide
concentration, the red ALARM LED starts flashing. If the concentration
remains unchanged, the detector sounds the alarm with a built-in siren. The
table below shows the detector signalling depending on the concentration
and exposure time. The detector reacts sooner with greater concentrations.
The siren can be silenced for 4 minutes by holding down the test button. If
the dangerous concentration persists, the siren is reactivated. The siren
cannot be silenced when the concentration exceeds 150 ppm.
NEVER IGNORE THE SIGNALLING
OF INCREASED CARBON
MONOXIDE CONCENTRATION IN
THE BUILDING
Note: The CO detector may sound if cigarette smoke is blown into it, or
aerosols are released nearby.
Hydrogen serves as a reference gas therefore the detector may report
false alarms in the case of its presence.

What to do when the alarm sounds
1) Open the doors and windows to ventilate the area
2) Turn off all fuel appliances where possible and stop using them
3) Leave the threatened area as soon as possible
4) Get medical help immediately for anyone showing the symptoms of
carbon monoxide poisoning (headache, nausea)
5) Do not re-enter the property until the Alarm has stopped signalling
harmful concentration of carbon monoxide. If the Alarm has been
silenced by pressing the test button, wait at least 5 minutes so the
Alarm can check if the CO gas has cleared.
6) Do not use the fuel appliances again until they have been checked by
an expert.
Note: If the carbon monoxide concentration has been decreased only by
ventilation, this might only be a temporary solution. It is necessary to find
the carbon monoxide source.
Detector testing, maintenance, fault indication
The detector regularly checks its function to ensure problem-free
functioning. Any fault is immediately signalled with LEDs or with a symbol
on the display (type Ei208DW).
It is further recommended to test the detector using a test button in the
following cases:
1) After the system is installed.
2) Regularly once per week
3) After prolonged absence from the building
4) After repair or servicing of any of the fossil fuel-burning appliances
5) Once per year using a CO gas testing kit

When a low battery, detector failure or end of life is signalled, the
detector has to be replaced.
The carbon monoxide detector has a limited usable life which runs
out even if the detector is not used. There is a label on every detector
showing its usable life. The detector has to be replaced after this date
even if it does not signal any faults.
The detector requires no special maintenance. Keep it clean by wiping it
with a wet cloth from time to time. Do not use any aggressive or abrasive
cleaning agents.
AudioLink
The detector supports AudioLink if it
has its symbol. The app can be
downloaded from Google Play or by
using the attached QR code. The app is
accessible just for devices with the Android
operating system and is only in English. The app
can read values from the detector (sensor status,
battery, number of tests, CO concentration, …) via
the detector’s chirping buzzer. This is not an app
from Jablotron Alarms but from the detector’s manufacturer. More
information about the app is available at http:/www.eielectronics.com
