The safety of property, but also the protection of health and life, are the most important. Acoustic signals play an important role in an alarm system. Thanks to them, each user has time to react. Of course, acoustic signals may have different volume levels. It is worth learning more about acoustic alarms to be able to choose the best ones.

Types of acoustic alarms
Not only optical signaling is important. Basically, in fire protection it is definitely not enough. An acoustic alarm that can have different sound intensity will work better. By emitting sound signals, it informs users about a threat. It is suitable for protecting both private and public facilities. Its application is therefore very wide. The acoustic alarm can also act as a deterrent by means of an intense sound signal. There are various types of acoustic alarms.
First of all, the division covers the working environment, so they are external - placed on buildings that are primarily resistant to mechanical damage. You can choose ones made of reliable plastic. Internal ones are also available, with the switch and indicator located in the building. Remember that external ones must have a wider operating temperature range and a higher degree of protection against damage. Their casing should also be resistant to ultraviolet radiation. Taking into account the method of alarming, we distinguish acoustic fire alarms with high sound intensity, e.g. at the level of 65 dB. The switch is connected to the network.
Background noise lasts longer than 30 seconds. We also distinguish acoustic fire alarms with a verbal message. Such signals allow the message to be conveyed quickly. This way the reaction time is shorter. They must work according to the alarm sequence and provide clear instructions. There are also acoustic fire models that operate using an acoustic and optical signal. Sounders can be activated automatically. The sound intensity changes in steps. The operating mode can be selected using a microswitch.
What does the acoustic alarm indicate?
The acoustic alarm quickly and effectively informs about the detected threat. Then an acoustic signal is emitted. It is worth noting that it can inform about the detection of, for example, a source of fire or smoke, as well as about an external threat, e.g. when privacy is violated and a private facility is entered. Such a signal also serves as a deterrent. Indeed, its sound is really intense, so there is a good chance that, for example, a potential thief will retreat. Please also note that sometimes there may be an accidental violation of, for example, the company's private property. In such a case, the signal will have an informative function.
How to properly connect the sounder?
For the siren to work properly, it must be properly connected. First of all, connect the power supply, usually 12 V, to the terminals. You also need to check the current efficiency of all alarm outputs, possibly those powered from the control panel. Please also note that the signals can work with various types of installations. Most often, they should be mounted to a flat surface. There is a four-position microswitch in the cover of the signaling device. Thanks to this, the device works efficiently. Of course, before starting work, you should read the user manual and use it to go through the next steps. Remember how important the potentiometer is, which is a single element. Thanks to it, you can properly derive the voltage divider.
Sounders at the Onninen wholesaler
The Onninen wholesale offer includes a wide selection of acoustic alarms. It is worth choosing the Gazex optical-acoustic siren, siren 105/70dB + red LED lamp, 12V, IP54, muting with the SL-32 switch . It must be said that this model is very popular and widely used among traffic lights. He is responsible for increasing the level of security. It operates in various decibel intensity ranges. Its dimensions are small, so it can also be placed in tight places. It is turned off using a button, which is a special switch. In case of danger, it emits a really loud sound signal.
The Cooper RoLP LX wall optical-acoustic signaling device is also worth attention. Element of the fire protection system, Cooper . It uses LED technology. First of all, it is placed as an element of the fire protection system. You can mount it on the wall and only need one mounting point. A good choice will also be the Schneider Electric 24V XB5KS2B4 continuous/intermittent buzzer . It has industrial applications. You can choose both a metal and a plastic model. Each of them has really high operational efficiency. This button can be part of an intelligent protection system that uses smart solutions.
