Necessary information about smoke detectors
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.
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.
