The smoke detector will

alert you, for example, when you sleep, if there is smoke. The more quickly it discovers a fire, the more

time and opportunity you have to leave your home safely. Do not take a risk and buy a smoke alarm for

your loving house. We distinguish three types of smoke detectors: optical smoke detector, ionization

smoke detector and the microwave detector. In this article, you will find every important informations

when making a purchase on a smoke detector.

Optical smoke detector

An optical smoke detector emits a bundle of light that is captured by a light-sensitive cell. If there is

smoke in the house, it emits light bundle but if the light does not reach the cell, it can not be collected.

The smoke detector detects this problem and raises the alarm. The majority of fires, especially in homes,

is a smoldering fire arises from which then develops into a large open fire. Smoke particles in a

smoldering fire are relatively large because they do not completely burn. An optical smoke detector is

more likely to detect larger particles than an ionization detector and thus save more alarms in a fire.

Combination detector

The combi sensor is a combined carbon monoxide detector and optical smoke detector. This combi detector warns

with a loud alarm if there is too much carbon monoxide in your home or when it detects smoke. The

alarm tones for both of these dangers are different from each other. This combination detector is ideal

for placement on the landing and in the small hall, usually it is placed between the stove and the

bedroom. Always consult the manual when you place the microwave detector in home for the first time.

Battery or mains

Both optical, ionization and microwave detectors exist in a version with battery or mains connection.

Smoke detectors with batteries (9 volt) are easy to install. Some batteries should last longer than many

years, but it is advisable to be replaced after approximately one year. It is strongly recommended to

purchase a smoke detector equipped with a low battery signaling. That is a signal to hear regularly for at

least 30 days when the battery needs replacement. There are smoke detectors, which have the

advantage that you do not need to replace batteries, are powered via mains. The downside is that they

do not work without the power (short circuit, fire) unless the detector is equipped with an emergency

power supply. This is a battery that is activated when the power is out.

Placement and type of home

It is recommended to hang a detector on the ceiling, as far as possible in the middle and more than half

a meter from the walls. Is there no possibility of placement on the ceiling, it can be placed on the wall at

about fifteen centimeters away from the ceiling. Do not place the detectors at a strong air as in a

diffuser, hinged window or over a radiator. The smoke detectors react to airborne particles that may be

smoke, but also dust and water vapor. The kitchen and bathroom are therefore also not good places to

place the smoke detector. The detector is easily mounted using the supplied screws. Clean the smoke

detector with a vacuum cleaner at least once a year.

In homes with single-storey (for example, an apartment house or bungalow), there should be one smoke

detector in most cases. The best place is in a hallway or corridor where fire in most rooms can be

detected. In homes with two floors, it is wise to place one smoke detector on each floor, preferably on

the top of the stairs or the ceiling on the bedroom floor. To maximize security, regardless of the number

of floors, you can place one in any room where people regularly stay. Thinking particularly of the living

room, bedroom (s) and any room where there is an electrical device. Preferably use detectors that can

be linked to each other so that if all detectors are in alarm, everyone in the house is alerted. Locate an

alarm in the ‘connecting room’ in areas that can only leave through another room. Even where smoke in

bedrooms or where used unattended electrical appliances, is recommended for a detector.
