Frequently Asked Questions - COWM370 ABUS

Where to install the COWM370 CO detector?

Place it in every room with a combustion appliance, bedrooms, and hallways. For wall mounting, install it at least 200 mm below the ceiling, 1-3 m from the possible source. In the absence of a source, place it at breathing height (e.g., nightstand). Avoid dusty areas, near windows or air vents.

How to test the detector?

Press the test/silence button. The detector emits 4 beeps and the LED flashes red 4 times. This confirms proper operation. Test it after installation, after each battery change, and ideally once a week.

What to do in case of alarm?

Stay calm. Open all doors and windows. Stop combustion appliances. Evacuate the building if the source is unidentified or concentration is high. Call emergency services from outside. Do not re-enter until the area is safe.

How to replace the batteries?

Remove the detector from its base (push upwards). Replace the two used batteries with new AA alkaline batteries (1.5 V) observing polarity. Reattach the detector by snapping it onto the base. A beep confirms power-up.

The alarm sounds without reason, what to do?

Press the test/silence button to silence the alarm for about 10 minutes. Check if a CO source is present (heater, chimney). If the alarm persists, evacuate and call emergency services. False alarms may be caused by nearby chemicals (solvents, paints, alcohol).

What is the detector's lifespan?

The electrochemical sensor has a maximum lifespan of 7 years from installation date. After this, replace the entire device. End of life is indicated by a yellow flashing light and a long-short beep every 30 seconds.

Can the COWM370 be used in a motorhome or caravan?

No, the device is approved only for residential use (houses, apartments). Its use in boats, caravans, mobile homes, or commercial premises is prohibited by the manufacturer.

What to do if the detector indicates a sensor error?

If the LED flashes yellow twice every 30 seconds with 2 beeps, this indicates a sensor error. The detector must be replaced immediately, as the sensor cannot be repaired.

How to clean the detector?

Use a cloth slightly dampened with soapy water for the surface. For ventilation slots, vacuum or blow out dust. Do not use chemicals, hard brushes, or flammable liquids. Do not wash in a dishwasher.

Can the detector detect gases other than CO?

No, this detector is designed exclusively for carbon monoxide. It does not detect smoke, heat, natural gas, butane, etc. Do not use it as a replacement for a smoke detector.

- According to EN 50291, the COWM370 ABUS CO alarm is designed and approved exclusively for detecting CO (carbon monoxide) in private homes!

• Application in industrial facilities, offices, boats, caravans or mobile homes is therefore not permitted!
• The battery-operated ABUS CO alarm COWM370 detects carbon monoxide (CO) in even low concentrations, then gives off an acoustic as well as optical signal.

Functioning of the device, Formation & dangers from carbon monoxide

- The purpose of the CO alarm is to protect persons against the acute effects of carbon monoxide. However, it cannot prevent the chronic affects of carbon monoxide exposure or offer persons with special risks complete safety.

• The CO alarm is not a substitute for smoke, fire or other alarms!
• It does not detect smoke, heat or other gases!
• In addition, the electrochemical sensor can only CO on time in a limited area (max. 60~m^2 , ding on the environmental conditions).

Formation & dangers from carbon monoxide

Poisonous effect

• Carbon monoxide (CO) is a colourless, odourless, non-irritating gas which can quickly become a deadly threat.
• Carbon monoxide bonds to the pigment of the red cells, thereby preventing the transport of n, which can lead to unconsciousness and by suffocation.

- High concentrations of CO can lead to death in just a few minutes!

Typical symptoms of poisoning

Low Mild headaches, nausea, tiredness, CO concentration flu-like symptoms

Medium Bad headaches, racing heart, vomiting CO concentration

Formation & dangers from carbon monoxide

High Cramps, confusion, unconsciousness, CO concentration cardiac arrhythmia

- Please note that the symptoms can occur earlier with children, pregnant women, senior citizens and persons with respiratory or heart diseases and even low CO levels could cause organ damage on children!

Sources of carbon monoxide & preventative measures

- Carbon monoxide is created, among others, during incomplete combustion processes (e.g. defective floor heating or clogged smoke outlets).

• Installing a CO alarm is not a substitute for the proper installation, use and maintenance of fuel-burning devices including related ventilation and exhaust gas systems.
• Have such devices/systems installed only by qualified persons. Acquire the devices/systems in perfect technical condition and have them regularly inspected!
  • Make sure that ovens, chimneys and the like are kept clean at all times!
• Never operate barbecues, deck ovens, heating devices or other devices intended for use outside inside closed rooms.

Behaviour in case of alarm, Selecting location

Selecting location

Behaviour in case of alarm

When a carbon monoxide alarm sends out a signal, take the following measures in the specified order:

(1) Keep calm and open all doors and windows to increase the rate of ventilation. Stop using all combustion devices and make sure that they are switched off.

(2) Leave the building in particular when the CO level is high or when the source cannot be instantly detected and alert occupants, if applicable.
(3) Call the fire service/rescue worker immediately from outside the building. Follow their instructions. Inform them that you assume carbon monoxide is being inhaled.
(4) Do not enter the area in question before the CO concentration has dropped to a non-critical value.
(5) Do not use the affected combustion device until the cause of CO emission has been removed by a professional.
(6) Check the functionality of the CO alarm after it has triggered (using Test button) and replace the batteries if necessary.

Selecting location

General

The design and spacial distribution of residential buildings as well as the number, type and location of carbon monoxide sources can vary greatly. However, there are general

instructions concerning where the device should and should not be installed to keep the risk of false alarms as low as possible.

Which room? Installation for optimum safety

• In every room that contains a combustion device.
  • In every room that is used as a sleeping area.
  • In every hallway per floor.
• In every room in which people spend long periods of time and from which they could not hear an alarm from another part of the building.

Minimum installation

If the number of alarms is limited or there are combustion devices in more than one room, the following criteria should be taken into account when installing the alarms:

• The alarms should be installed in rooms which contain a device without a smoke outlet or with an open smoke outlet.
• The alarms should be installed in rooms in which occupants spend the most amount of time.

Where in the room?

Carbon monoxide (CO) has almost the same density as air and therefore distributes itself uniformly in space. Consider the following points when positioning the CO alarm:

It is impossible to give exact instructions on the correct arrangement of an alarm which apply for all types of rooms and their use. The following points should be taken into account when choosing the optimal location for each corresponding situation.

Selecting location Behaviour in case of alarm, Selecting location

Alarm located in the same room as a combustion device

When CO escapes from a combustion point, the heat initially rises. This is why you should install alarms as high as possible on a free wall in rooms with combustion devices, while considering the following points:

• The alarm should be assembled on a free wall, at least 200 mm below the ceiling.
• Install the alarm at a height at which you can reach it without tools and at which you can see all alarm displays. (Between chest and head)
• The alarm should be at a horizontal distance of 1 to 3m from the possible source of carbon monoxide.
• If the room is divided, the alarm should be on the same side of the division as the possible source of carbon monoxide.
• In rooms with slanted ceilings, the carbon monoxide alarms should be installed at the higher side of the room.

Alarms located in bedrooms and rooms far away from combustion devices

In rooms located far away from combustion devices, the carbon monoxide has already cooled to room temperature. Due to the fact that CO has nearly the same density as air, it distributes uniformly in the air.

Consider the following points:

- In bedrooms and in rooms which are located far away from combustion devices, the devices should be at the breathing level of the occupants (e.g. "desk level" at the bed-side table

in bedrooms and "eye level" in living rooms).

- Make sure there is sufficient spacing to the ceiling as well as to corners and furnishings (min. 200 mm).

Where alarms should not be installed

• outside (use only possible in closed rooms);
• where they can be blocked (e.g. by furniture);

• on ceilings (only suitable for wall installation);

• next to a door or a window (reliable detection cannot be guaranteed);

• next to an air duct or similar ventilation opening;
• in areas in which the temperature can fall below -10^ C and rise over 40^ C;
• in rooms that are exposed to large amounts of dust/dirt or grease.

Installation and start-up

The following two variants are possible for operating the CO alarm:

Wall installation

Take the following steps in the specified order to install the alarm on the wall:

1. Hold the mounting base in a horizontal position at the desired location and mark the drill holes.
2. Drill the holes with a suitable power drill 5 mm at the previously marked locations.

Installation and start-up Display and functions

sure not to damage any cables! Keep CO alarm away from getting plaster dust when drill the holes!

1. Press the plastic dowels into the drill holes and screw the mounting base with the two supplied screws.

Desk-stand

"At breathing level" in bedrooms and living rooms without combustion devices during operation.

1. Use the two feet to place the alarm on the bottom side of the housing on a flat, dust-free base.
2. Make sure that the alarm is standing securely and no objects prevent CO from entering the alarm.

Start-up

1. Remove the protective strips from the inserted batteries - the warning tone sounds and the CO alarm is ready for operation.
2. Then enter the current date (date of installation) on the label on the bottom of the alarm with a water- and smudge-proof pen: e.g. 30.04.2022.
3. To mount on the wall: Place the CO alarm onto the mounting base from above until it clicks into place.

Testing the device electronics

Check the function of the CO alarm by pressing the test button. To protect your hearing, keep away from the device!

The alarm sounds four times and the LED flashes four times.

This does not signalise that CO is present in the room; it is a confirmation that the alarm is functioning properly.

Test the alarm function after installation and after every battery change without fail (wait about 5 seconds after establishing the battery contact). A regular weekly test is also recommended.

Troubleshooting

Test: If the CO alarm does not react after a functional test has been performed, first check that the batteries are inserted correctly (polarity).

If the detector does not react to a new function test even after this, please contact your dealer.

Weak batteries: If the CO alarm signals low battery performance, replace the batteries immediately, at the latest within 7 days. Only use 1,5 V brand alkaline AA batteries of the same type.

Malfunction: If the CO alarm registers a sensor error, the complete alarm must be replaced - the sensor cannot be replaced!

The end of sensor lifespan: The lifespan of the electrochemical sensor is 7 years. If the end of the lifespan is reached, the complete alarm must be replaced immediately!

Care and maintenance

Cleaning

• Dusty detectors must be cleaned. You can clean dust from the air vents of the detector using a vacuum cleaner or compressed air.
• If necessary, you can remove the dust with a brush.
• You can clean the surface using a cloth slightly dampened in soapy water.
• Do not allow water to penetrate inside the device!
• Do not clean the device in a dishwasher!
