Last year, after the law came into force, we bought massive wireless smoke detectors. None of us needed to experience how they worked, or perhaps to avoid the fire.
However, a smoke detector is not the only device to protect our home or residents. Similar wireless devices can protect us from leakage of gas, underwater water, flooding or unwanted guests. But are the devices always safe? Imanta Baltrūnaitė, project manager of the Electronic Distributors Association (EPA), recalls that improperly maintained wireless sensors can cause problems.
Unattended equipment can contaminate your home
"All these wireless devices – smoke, fine, water, motion or interruption sound sensors or door-mounted contact sensors – detect different parameters of the changed environment signaled by special signals, but all similar equipment has one common function: works with batteries: a battery-like attitude, imprudence and ignorance can lead to such devices not only protecting our house invisibly, but also impure pollution, but negatively affecting our health, "says the specialist.
According to I. Baltrūnaitė, the greatest risk of contamination of the home environment comes from batteries used for household safety devices. If these batteries are empty and we do not care for them, the devices will not only stop working, but as a result of further battery changes, they can become a health hazard. It indicates that the normal life of batteries is up to 18 months, but that this period can be significantly reduced, depending on the conditions of use. Moreover, the battery life is shortened and unused, so it is often difficult to estimate the lifetime of new batteries, not to mention the battery life.
Air temperature and air humidity are affected
"If wireless devices are improperly installed or configured, battery life can be significantly reduced Batteries are discharged faster with a weaker connection between the wireless device and the security system Although some touch devices have a system that warns of low battery life, there is a sudden failure of a battery to damage the whole device, along with the aforementioned warning system, in which case the device not only stops functioning, but also causes harmful substances to enter the environment. can chemically influence both the battery and the device itself, to become toxic fumes, "emphasizes Baltrūnaitė.
It reminds us that the chemicals used to make batteries require us to properly control the batteries, paying attention to the effects of both negative and higher temperatures than +30 ° C. In the case of batteries, the temperature of the environment in which they are charged is also assessed. The correct temperature for charging and storing batteries is between +10 ° C and + 30 ° C, and it is not advisable to store or charge them in a humid environment.
Jūris Targonskas, head of the fire control committee of the Fire Department and Rescue department, points out that we need to be particularly alert to the maintenance of the smoke detector, which we had to install at our home since 1 May 2018.
What to do if the instructions for checking the sensor have been lost? Mr. Targonskas identifies a number of important steps in the maintenance of smoke detectors.
5 steps to properly maintain a smoke detector
1. Clean the dust from the smoke detector regularly.
2. Press the test function button to check that the device is working. If the detector works during the check – everything is fine and there is nothing to worry about.
3. Note the periodic warning light. You will hear a warning when you press the test function button.
4. If you have checked the detector using the above methods and have not received the result, replace the battery.
5. If the device still does not work after replacing the battery, it is advisable to purchase a new device. Note that there are two types of smoke detectors: with replaceable batteries and non-replaceable. The former are cheaper, but batteries need to be replaced every 1-1.5 years, and the second usually takes up to 10 years and is then replaced with new ones.
According to the PAGD representative, the same rules apply to the sub-sensor, which is not mandatory. He also pointed out that some fires in 2018 could be avoided under the proper supervision of smoke detectors. In many cases, the smoke alarm did not work and could not be activated because the battery was removed. This is usually done by smokers at home – they do not like the smoke detector to prevent them from voluntarily living in a smoky environment.
I. Baltrūnaitė also points out that damaged devices that are no longer worth repairing, and devices that are no longer usable, are hazardous to the environment and human health, especially if we store this equipment in the wrong conditions. It also recalls that it is not difficult in Lithuania to safely dispose of waste electrical and electronic equipment. Batteries and devices with small touches can be left in supermarkets, electronics stores, libraries and elsewhere – there are about 4000 in Lithuania. such places.
