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

Types of acoustic signals
Not only visual signaling is important. In principle, it is definitely not enough in fire protection. An acoustic signaling device, which can have different sound intensity, will work better. By emitting sound signals, it informs users about the occurrence of a threat. It will be suitable for the protection of both private and public buildings. Its application is therefore very wide. An acoustic signaling device can also act as a deterrent with an intense sound signal. We distinguish different types of acoustic signaling devices.
First of all, the division includes the working environment, so there are external ones - placed on buildings, which are primarily resistant to mechanical damage. You can choose those made of reliable plastic. There are also internal ones, whose switch and indicator are placed in the building. Remember that external ones must have a wider operating temperature range and a higher degree of protection against damage. Their housing should also be resistant to ultraviolet radiation. Considering the method of alarming, we distinguish acoustic fire alarms, which have a high intensity of the generated sound, e.g. at the level of 65 dB. The switch is connected to the network.
Background noise lasts longer than 30 seconds. We can also distinguish acoustic fire alarms with a verbal message. Such alarms allow for quick transmission of the message. In this way, the reaction time is shorter. They must work in accordance with the alarm sequence and provide clear instructions for action. There are also acoustic fire models that operate using an acoustic and optical signal. Sound alarms can be switched on automatically. The sound intensity is changed step by step. Using a microswitch, it is possible to select the operating mode.
What does the acoustic signal indicate?
An acoustic alarm quickly and effectively informs about a detected threat. Then, an audible 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, for example, in a situation where privacy is violated and a private property is entered. Such an alarm also acts as a deterrent. Indeed, its sound is really intense, so there is a good chance that, for example, a potential thief will retreat. Also note that sometimes there may be an accidental violation, for example, of a company's private area. In such a case, the alarm will serve an information function.
How to properly connect an acoustic signal?
In order for the alarm to work properly, it must be connected correctly. First of all, the power supply must be connected, usually 12 V to the terminals. You must also check the current efficiency of all alarm outputs, possibly those powered from the control panel. Note that alarms can work with various types of installations. Most often, they should be mounted to a flat surface. A four-position microswitch is located in the alarm cover. Thanks to this, the device works effectively. Of course, before starting work, you should read the instruction manual and use it to go through the next steps. Remember also how important the potentiometer is, which comes in the form of a single element. Thanks to it, you can properly derive the voltage divider.
Acoustic alarms at the Onninen wholesaler
In the Onninen wholesale offer you will find a wide selection of acoustic alarms. It is worth choosing the Gazex optical-acoustic alarm siren 105/70dB + red LED lamp, 12V, IP54, muting with a switch SL-32 . It must be said that among alarms this model enjoys really great popularity and wide use. It is responsible for increasing the level of safety. It works in a different range of decibel intensity. Its dimensions are small, so it can also be placed in tight spaces. It is turned off by a button, which is a special switch. In the event of a threat, it emits a really loud sound signal.
The Cooper RoLP LX wall-mounted optical-acoustic signalling device is also worthy of attention. It is an element of the fire protection system (P.POŻ), Cooper . It uses LED technology. First of all, it is placed as an element of the fire protection system. It can be mounted on the wall and only one mounting point is enough. 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 plastic model. Each of them has really high operating efficiency. This button can be part of an intelligent protection system that uses smart solutions.
