Smoke Detectors: Functions, Types, And Maintainance

Smoke alarms can save lives, as the greatest danger in a fire often comes from the unnoticed development of smoke gas. The representatives of the insurance industry and the fire services have been pointing out this fact for several years. In addition to the classic smoke detector, there are now also wireless smoke detectors or WiFi smoke detectors that offer extended functions.

Why are smoke detectors necessary?

A smoke detector reacts quickly to danger with a loud signal. As a result, the residents are warned and can immediately get to safety and alert the fire brigade. Because fire is not always recognized quickly. On the one hand, most fires in the home are caused by technical defects that are not noticed or noticed too late. On the other hand, according to the “Smoke alarms save lives” campaign, around 35 percent of all fires happen at night and cause over 70 percent of the fatalities.

The reason is clear: at night the fire is not noticed or is noticed too late. As a result, the development of smoke gas has progressed so far that humans can no longer do anything and die as a result of the poisoning.

Just one or two flue gas breaths can be enough to throw a person into deep unconsciousness, and a few more can be fatal. This fact turns out to be fatal, especially at night. When a person sleeps, his sense of smell is switched off. For this reason, it can happen very quickly that he no longer wakes up when he is poisoned by smoke.

Types of smoke alarms

Smoke detectors can be installed individually or networked. The networked smoke detectors are controlled via radio, cable, or WiFi.

Wireless smoke detector

Wireless smoke detectors have the advantage that all devices in the network sound the alarm if smoke is detected at one point. For this reason, the networked smoke alarms are particularly suitable for houses, larger apartments, and for households with children. The installation of wireless smoke detectors is also worthwhile in the commercial sector.

Thanks to wireless interconnected smoke detectors, the alarm can also be heard when the residents are far away from the source of the fire. Single smoke detectors are usually sufficient for smaller apartments or rooms.

Smoke detectors in the age of smart homes

The smart home is also an issue in the area of ​​fire protection. Intelligent smoke alarm devices can be linked to various devices. If wireless smoke detectors connect within the house over a limited distance, WiFi smoke detectors go even further. These fire detectors connect via the Internet and can therefore be controlled from any location using a smartphone or tablet.

If the house is currently empty and the fire alarm detects smoke, it informs you via SMS or push notification and, ideally, sends an emergency call to the fire brigade itself. So in the future, intelligent smoke alarms can save even more people’s lives. The smoke alarm also informs you as soon as the battery is running low. Even if the WiFi should fail, the smoke alarm devices work perfectly.

How to maintain a smoke detector?

Most devices are equipped with a built-in long-term battery that has a service life of more than ten years for high-quality smoke alarms. If the battery is empty, the device must be replaced. A battery change is expressly intended for other smoke alarms. It must be done so early that there is no serious danger and full functionality is guaranteed at all times. The battery charge indicator provides information about the condition of the battery: As a rule, smoke detectors have a light-emitting diode display or they use a signal tone to indicate that a battery change is necessary.
