For many motorists, an alarm system installed on a car is a guarantee of its safety and security. Of course, especially determined pests can cope with almost any security system, but petty thieves and ordinary hooligans try to avoid such cars. There are times when an alarm system designed to help the car owner acts against him. The standard “antics” of the security system are sometimes simply amazing in their simplicity, but the driver is not at all amused at that moment.
Just imagine that you walk up to your car, press a button on the remote control, and in response... nothing. The alarm does not respond and the car does not open, and when you try to use the key it starts screaming like crazy. Agree, it’s not very pleasant – especially if an important meeting is disrupted, or you have other urgent matters. What to do? It would probably be best to disable it, but more on that a little later, but now let’s find out what reasons can cause the above-mentioned operational failure.
1. Typical causes of malfunctions in car alarms
The inability to remove the car is not the only problem with the operation of this device. It often happens that it cannot be turned on, as a result of which the machine is left without proper protection. There can be several reasons for such malfunctions, but the most typical are the following:
Battery malfunction, which can occur even while the vehicle is moving. To verify this theory (or disprove it), turn on the ignition and look at the instrument panel. If it doesn't work, then most likely the problem really is a dead battery. In this case, turning off the car alarm should be limited to turning off the siren, after which you can proceed to restoring the functionality of the battery.
Radio interference, often present in large cities. All kinds of mobile operators, large enterprises, parking lots and various concrete structures - these are the factors that block the signal from the remote control and do not allow the alarm to go off at the right time. To eliminate “obstacles,” try turning off the alarm by reducing the distance between the car and the remote control: bring it to the installation location of the receiver with an antenna or to the location of the central unit of the device.
One more A typical problem with a car alarm is a power failure of its key fob, so first you need to make sure the battery is working. On devices with one-way communication, pressing any button should cause the indicator light to light up, and if this does not happen, then the battery needs to be replaced.
The liquid crystal display of key fobs with two-way signaling should display information about the charge level. If at the moment it is not possible to buy a replacement part, you can try to “resurrect” the old one for a while: remove the battery from the key fob and knock on it. Sometimes a slight deformation of the battery helps you turn off the alarm and get to the nearest point of sale of new batteries.
2. How to turn off the alarm yourself?
When problems arise with the alarm system, some car owners prefer to immediately call an electrician, since Often the first and main cause of a malfunction is incorrect installation of the device itself, and here it’s unlikely to be possible to do without outside help. In such a situation, the alarm does not respond to the “commands” of the key fob, locked car doors do not open, and the device does not allow the engine to start.
However, if the described symptoms appear, it is worth checking the remote control’s battery - the battery may have failed. If everything is fine with her, then you can proceed to directly disabling the alarm. But first, in order not to attract unnecessary attention to yourself, turn off the device's speaker by following these steps: open the hood, find the bell and use the alarm key to turn off the sound. No key - just disconnect the contact.
The easiest way to turn off an alarm is to switch it to service mode (“valet”). A secret button will help you complete the task, which is usually installed near the fuse box in the passenger compartment or under the dashboard. If you installed the alarm yourself, then finding it is not a problem at all. A detailed description of the process of disabling the security system using the above button can be found in the device’s operating instructions (section “Disarming using a secret button”). True, it is quite likely that some instructions simply do not have such a section, then the only way out is to call the service center where the alarm was installed.
Once you find the button you need, enter the special code. Typically this is done in one of the following ways:
Turn the key in the ignition, press the button once and turn off the ignition;
Turn the key in the ignition, press the button four times and also turn off the ignition.
However, before proceeding to direct actions, you should study in more detail the instructions for entering the “PIN code”, which is especially true for owners of complex “GSM alarms”. After completing these steps, start the car and connect the alarm speaker. The second simple option for disabling a car alarm and then checking it is to diagnose the fuse. It can be found either under the hood, where it is located near the central unit, or on a bundle of wires located under the instrument panel. If the described methods for disabling a car security system did not bring the desired result, then the problem is deeper, and it will no longer be possible to avoid calling a mechanic.
It should be noted right away that most of the recommendations described below will only work in cases with simple alarms, since more advanced systems have too high a level of complexity (for example, the same), and they cannot be dealt with so easily. Be that as it may, before starting work, you must carefully study the technical characteristics of the installed system and its instructions.
So, when disconnecting, try not to interfere with the operation of the device itself, as this may lead to its breakdown. To achieve this goal, it is best to use a stationary shutdown, because many modern alarms are quite complex mechanisms, the design of which involves connecting as many different vehicle systems as possible. Thus, alarm manufacturers hope to secure the car to the maximum.
If problems have already appeared, then dealing with them manually will be quite problematic, so first of all you need to focus your efforts on eliminating obstacles that prevent the engine from starting. After this, the best option for further developments would be to visit the appropriate service center, whose specialists will perform a full diagnosis of the system and restore its functionality. I would also like to give a few recommendations for those motorists who are planning to purchase a car with an already installed alarm system, because you can never be 100% sure of such protection.
Firstly, find out from the former owner how to change the remote control code and emergency alarm code, and then be sure to change them. Secondly, additionally find out how to disarm a car in the event of a system failure or if the key fob is lost, how to switch the alarm system to the “Valet” service mode, how the engine is blocked, where to find blocking relays, and what type of blocking is used on them. If for some reason you cannot obtain the specified information, then it is advisable to find the instructions for the system or at least find out where exactly it was installed.
The next step towards diagnosing the alarm system is checking its security mode, and the following points must be taken into account:
1.
The range of the remote control must correspond to the device's passport data (as a rule, this is at least 5 meters). In case of short range, it is necessary to replace the power supply or check the frequency of the transmitter by contacting an appropriate specialist for help (usually the standard value corresponds to 433.92 MHz, and for older and non-certified systems - 305-315 MHz).
2. The reaction to opening the doors, hood or trunk lid should be expressed in the immediate appearance of a corresponding signal lasting 30-60 seconds. The presence of a short-term signal indicates that the alarm occurred in the warning zone of the shock sensor, and the contact sensor is inoperative. Turning on the system, accompanied by a “croaking”, or its activation with braking (5-45 seconds after arming), indicates a malfunction of the contact sensor circuit.
3. Also It will be useful to check the reaction of the alarm system to impacts on the wheels and front pillars. A single-level shock sensor should respond with a long (30-60 second) alarm signal. With a two-level device, the reaction to a weak impact is expressed in one or more warning “croaks”, and the reaction to a strong impact will be the same as in a single-level device.
Note! Rocking the vehicle will not contribute to the activation of the security system, because it is no coincidence that the sensor was called “shock”.
4. If the installed alarm system includes a glass break sensor, then the reaction to hitting the window with a coin, ideally, will be the same as in the previous paragraph.
5.
In the case where the alarm is equipped with a single-level or ultrasonic microwave sensor, moving in the cabin or trying to get into it will cause a long sound signal. In vehicles equipped with such sensors, it is not allowed to decorate the interior with any decorative “hangings” in the form of dolls, skeletons or deodorants. Often, the installation of a microwave sensor is carried out in the area of the handbrake, but you need to know that it cannot tolerate metal being placed above it.
6. The movement of people around a vehicle with a built-in two-level microwave sensor should trigger a siren, represented by a single “croak” or a series of them. Please note that the sensor should only be activated when moving!
7. If there is a position sensor, the alarm response to jacking will appear in the form of a continuous alarm.
8. Unauthorized starting of the engine (when turning the key in the ignition) causes the siren to sound in a cycle of 20-60 seconds, and the engine should not start.
9. It is necessary to pay attention to the fact that in the alarm mode the siren works at full strength, without failures and “wheezing”, and the emergency shutdown when the battery terminal is removed ensures that the “sound” stops as soon as the key is turned to an angle of 90°C.
10. You can also check the light part of the alarm, since turning the alarm on/off in normal mode is accompanied by flashing headlights, light and sound effects.
An important part of alarm diagnostics is measuring the current consumed by the machine on which it is installed. The measurements are carried out using a special device, the probes of which are installed in the open circuit of the standard battery and the terminal removed from it. When performing the procedure, you should pay attention to the following points:
1. The difference in measurements between the two values is the alarm current consumption in operating mode, the value of which should not exceed more than 50 mA.
2. When the alarm is turned off, the electrical equipment of the car should not consume more than 100 mA, otherwise you need to seek help from an auto electrician who will help you find the source of the battery discharge.
3. If the measurement results show that both values do not deviate much from the norm, but the battery still discharges quickly, then most likely the problem is in the battery itself.
In addition to numerous standard applications, settings and functions, the Windows operating system is also equipped with standard sound effects that we can hear while working in it. These sounds include signals about system startup, a signal about minimizing and maximizing a window, a signal about closing a program, a signal about an unauthorized action, and many other signals.
All these sounds are indicated in the system in the form of a Windows sound scheme. And this very scheme is very annoying to many users around the globe. Fortunately, Windows is quite flexible in terms of user customization, so the sound design can be modified to suit your needs and tastes.
In this article, we have collected ways to change the sound effects of Windows, and it does not matter what system you use, since it does not matter - the settings are almost identical on all versions. So, let's look at the question that worries many - how to turn off Windows sound effects?
Ways to disable Windows sound effects
Disable all sound effects
- Find the Dynamics icon in the notification area, among other trays in the system.
- Right-click on it and select “Sounds”.
- You can also do this through “Start→Control Panel→Hardware and Sound→Sound.”
- Go to the “Sounds” tab.
- Click on the "Sound Scheme" drop-down menu.
- Select "Mute".
- To turn off sounds when Windows starts, uncheck the “Play Windows startup ringtone” option.
- To disable sounds for specific occasions, such as Alerts, Battery Alarm, Critical Error, Message Notification, etc., select a sound effect from the list, then click the drop-down menu and select “None.”
- And finally, click “Ok” to confirm the changes and close the window.
Changing sound effects
If you prefer to listen to the standard Windows sound scheme for some reason, then you may be advised to modify these sounds. To change notification sounds, alerts and other important events in the Windows operating system, you will need to do the following:
- Open the sound scheme settings window for your OS again.
Go to the “Sounds” tab. - Select the system event in the list whose sound you want to change, and then click on the “Check” button to hear the melody itself.
- To use your audio files, click on the “Browse...” button and select the file you need. Note: The audio file must be in .wav format.
- To save the file as a sound effect, click “Save As...” and enter its name.
- Once the new sound effect is saved, select the desired system event and select the sound you just created.
Disable click sound in Windows 7 Explorer
- Open Windows Sound.
- Click on the Sound Scheme drop-down menu.
- Select the Silent option.
As you can see, modifying Windows OS is quite simple and no one has taken this function away from you. Now you can continue to use the system in complete silence and no event in it will irritate you so much.
Apple Watch owners should remember that before starting a movie or, for example, before an important meeting, they need to put not only their iPhone, but also their smartwatch into quiet mode. Turning off sounds and alerts on Apple Watch is just as easy as on iPhone, and you can do it in two different ways.
Users planning to use Do Not Disturb mode on their Apple Watch should keep the following in mind:
- Putting your Apple Watch in Do Not Disturb mode does not turn off the watch's haptic feedback to your wrist.
- Do not disturb does not apply to alarms or timers. This was done by Apple engineers so that users do not miss anything truly important. If, for example, you do not want your sleep to be disturbed by an alarm clock, manually turn off all set alarms and timers.
- If you forget to put your Apple Watch in Do Not Disturb mode and it starts making noise at an important event, just cover the watch screen with your hand. This will instantly “shut up” the clock and you will not disturb others.
How to turn off sounds and alerts on Apple Watch through the watch interface?
Step 1: Press the Digital Crown until you see the watch face
Step 2: Swipe up to go to the screen settings menu Preview
Step 3: Click the button Mute
In order to return the “voice” to your Apple Watch, you need to do the same steps in reverse order.
How to turn off sounds and alerts on Apple Watch through the iPhone interface?
Step 1: Launch the Apple Watch app on your iPhone
Step 2: Select Sounds & Haptics
Step 3: Move the Mute switch to the active position
A fire alarm installed at home or in an office is a guarantee of safety, preservation of material assets and the very life of the owner. However, most of these systems are quite technically complex. If false, how to turn off the sound and light signal? For most models there is a single algorithm of action - instructions for false alarms, which are issued by the company that carried out the installation.
However, if the installation was carried out independently, there are several recommendations, the implementation of which will not only get rid of annoying sounds, but also keep the alarm in good condition.
- First of all, you need to make sure that the alarm was indeed false. To do this, you need to go to the controller and, based on the indication on the panel, determine which loop the signal came from. Check detection area. If the device does not provide such information, you need to go around all the rooms where the detectors are installed and check that there is no fire. If smoke is detected (perhaps someone just lit a cigarette), the alarm should turn off.
- If no visible reasons for the operation are found, you can turn off the sound signal on the central unit. This process can be carried out in different ways, depending on the brand of the device. Most manufacturers include step-by-step instructions when a fire alarm is triggered inside the technical documentation or product data sheet.
In the absence of such information, you can use several standard commands that most devices support:
- Press the button under the bell icon several times (if there is one);
- On the dashboard dial, you need to press the star button several times;
- Press the hash mark, dial the number of the triggered loop (detection zone) and press the asterisk.
It should be noted that even if the alarm is turned off, this is only the first stage. It is still necessary to detect the breakdown and fix it. As a rule, they start with preventive cleaning of detectors located in the room where the failure occurred. Then, in the same room, the lines connecting the sensors to the loop are checked for short circuits. And only after that it is checked for serviceability itself.
If all the actions described in the instructions when the fire alarm goes off do not produce the desired effect and after turning it on it continues to ring, you need to call a specialist from the service company. Until this time, you can disconnect the defective detector from the cable and connect the bare wires together if the sensor was “normally shorted”, or disconnect them and carefully insulate them separately if “normally disconnected”.
To prevent false positives, you must follow a few simple rules. Carry out preventive cleaning of detectors from dust at least once every six months. Before cosmetic repairs, it is advisable to seal the detector with something dense: construction tape, electrical tape or polyethylene to prevent dust from entering.
If the fire alarm beeps in an apartment, what should you do if the faulty sensor is localized, but it is not possible to turn off the entire system? For example, a hybrid network is paired with video. 
The most radical method, which is strongly recommended not to be resorted to, is to run completely from both the mains and its battery, which maintains its operation. This measure is temporary for the period of repair work or waiting for the technician.
You can also de-energize the detector supplying the signal in several ways: disconnect it from the loop from the control module; de-energize the detector itself, or, as a last resort, cut off the leads soldered to the detector.
