  • Two types of models can be distinguished in terms of battery life. Cavius offers smoke detectors with five or ten years battery life.
  • Before buying a smoke detector, you should inform yourself about its operation, smoke detection range and additional functions.

What distinguishes Cavius smoke detectors from other manufacturers?

In contrast to other manufacturers, Ra […]

Since 2010, Cavius has been producing these smoke detectors and regularly develops them further.

Although the smoke detector is so small, it achieves battery lifetimes of 5 to 10 years. This means that once the smoke detector is installed, you don’t have to worry about your safety for several years.

How does a smoke detector from Cavius work?

The Cavius smoke detectors work photo-optically like most of the detectors on the market. This means that inside the smoke detector infrared rays are radiated onto a sensor. If smoke develops in your home, smoke particles penetrate the inside of the smoke detector, interrupting the infrared rays. If this happens, the smoke detector sounds the alarm.

Compared to other smoke detector functions, the photo-optical one shows a particularly high reliability. This also explains the widespread use of this type.

What distinguishes a Cavius smoke detector with a 5 year battery and what are its advantages and disadvantages?

The smoke detector with a battery life of five years is characterized above all by the fact that it is always technically up to date. This means that the product always incorporates the latest technology and therefore always functions as effectively and reliably as possible.

If new functionalities are developed, you can buy them immediately after the five years have expired.

In addition, the smoke detectors with the five-year battery cost less. So if you want to equip your entire apartment with smoke detectors, you will get a lower total price.

Advantages

Up-to-dateness of the product
Latest technology installed
Lower price

Disadvantages

Other DIN standards may be necessary

However, these smoke detectors initially cost a little more to purchase.

Furthermore, the technology in your product is no longer up to date after a few years. In addition, it is possible that after a few years other DIN standards exist which must be observed. For this reason it is important to always stay up to date if you buy this product.

Purchase criteria: You can compare and rate Cavius smoke detectors based on these factors

In this section you will learn about different aspects that you can use to compare different smoke detectors.

These are the following criteria:

  • Functionality
  • Smoke detection area
  • Mute
  • Test function

In the following paragraphs we will explain what is important for the individual criteria.

Functionality

In the following table you will learn about the different modes of operation of smoke detectors. There are three basic types: photo-optical, thermo-optical and ionisation smoke detectors.

Smoke detection area

The smoke detection range is the maximum range in which a smoke detector can detect smoke. In other words, the size of the room in which your smoke detector will work reliably.

It is important to keep an eye on the smoke detection area when buying a smoke detector.

Smoke detectors usually have a smoke detection range of up to 60 m², according to the manufacturer Cavius. Nevertheless, it is important to consider also the cut of the room. For example, if you have a particularly long room, it is advisable to install two smoke detectors. This will ensure that the smoke detector works as intended.

Mute

The purpose of muting a smoke detector is to prevent it from reacting to smoke for a short period of time. After pressing a button, the alarm is therefore muted for the specified time, usually a few minutes.

The Cavius smoke detectors also have this function. They can be muted for 10 minutes if required. When this time has elapsed, the smoke detector automatically returns to operating mode.

Test function

If you have had your smoke detector for a long time, it is usually useful to be able to check whether it is still working at all. You don’t have to produce smoke for this, you can simply use the test function.

This can be triggered by pressing a button and the alarm tone sounds. If the smoke detector remains silent, you have to get a new one.
