Comparison Pandect X-3110 vs Pandect X-3150

The number of independent security zones provided in the alarm system.

Each independent zone has its own set of sensors — for example, one zone can cover the doors, the second — the boot, the third — the hood, etc. This, in particular, makes it possible to determine in which place an attempt was made to penetrate, a blow occurred, etc., and to give an appropriate signal — up to showing a specific place of operation on the display of the key fob with two-way communication (see "Type of communication"). In addition, separate activation / deactivation or a time difference can be provided for individual security zones. For example, upon auto-arming (see "Security and Protection"), the alarm for the doors can be activated immediately, and for the boot — for some time later, which will make it possible to calmly pick up things from there.

The simplest modern car alarms have 1 – 2 security zones, in advanced models this number can exceed a dozen (which, in particular, allows you to provide your own security zone for each individual door).

— Quiet security mode. This mode assumes the complete absence of sound signals in the event of an alarm. In models with one-way communication (see "Type of communication"), the warning is usually carried out by light signals (flashing headlights), with two-way notification sent to the key fob or other device. Anyway, the silent mode can be very useful when extra noise is undesirable — for example, at night, when a siren could disturb people around.

— Silent setting / disarming. The ability to silently turn on and off the security mode, when the alarm reports a change in the operating mode only by light signals or notifications on the key fob (or other control device). This function will be very useful if you need to keep quiet (for example, at late hours of the day or early in the morning), or if you do not want to give others (including possible intruders) unnecessary signals about the state of the machine.

— Automatic arming. Possibility of automatic arming of the alarm system. Usually, this happens after the ignition is turned off and all doors are closed. The meaning of this function consists of two main points. Firstly, it reduces the likelihood of forgetting to turn on the armed mode and leaving the car unprotected. Secondly, automatic arming eliminates the need to once again give signals from the key fob and makes it difficult for intruders trying to...read the signal using a scanner.

— Arming delay. The ability to delay the automatic arming of the car (see above) for some time — usually within a few minutes. This feature will be especially useful if, after getting out of the car, it often becomes necessary to return to it — for example, to pick up some things.

— Security with the engine running. The ability to arm the alarm when the car engine is running. This feature can be very useful if you need to go away, leaving the car unattended, and it is undesirable to turn off the engine — for example, if it is turned on to warm up before an urgent trip.

— Security of the perimeter. Perimeter protection provides protection against illegal entry into the car: an alarm system with this function is able to respond to door openings, and in the case of using additional limit switches (see “Supplied Contents”), also to opening the hood and/or boot. In this case, the signal can be triggered not only when opening directly, but also when trying to open.

— Blocking a stolen car (Anti-Hi-Jack). The ability to block the engine or control in case of theft or forceful seizure of the car. The specific implementation of this function may be different. For example, some alarm models provide protection against robbery: if the driver's door is opened with the ignition on, the timer starts, and if after a while the driver does not turn off the Anti-Hi-Jack (by pressing a hidden button, entering a code, or in another way that is not available intruder), the system blocks the car. In other models, the activation of this function can be carried out remotely — for example, by a signal from a mobile phone. Also, blocking can be accompanied by other actions of the system — for example, turning on a siren or locking doors to detain an intruder.

— Disarming in two stages (AV). When using this function, to completely disarm the car, you need to send a command from the control device twice: the first command unlocks only the driver's door, and the rest open only when the button is pressed a second time. In this way, protection is provided against thieves — “purse holders” and other intruders who can enter the car through doors that are not controlled by the driver.

— Service mode (Valet). A special mode of operation in which all signals and warnings are turned off, however (in some models) the ability to control car locks through the alarm remains. This function is convenient when using the services of service stations, car washes and other services, when completely “legal” effects on the car can be perceived by the alarm system as signs of intrusion and cause false alarms. When the system is in Valet mode, the driver does not have to leave the control key fob to the service centre personnel, which minimizes the possibility of signal scanning.

— Management of a regular key fob. The ability to control alarm functions using a standard key or vehicle key fob.
Modern cars and other vehicles are equipped with more and more complex electronic systems, and to control these systems, a regular key or key fob is often used. The same key/trinket can be used to control the car alarm. Of course, the specific functionality of such models can be different, it's ok to clarify it separately. The same applies to the compatibility of the signaling with a specific key or key fob — different manufacturers may use different communication standards, and it will not hurt to clarify the support of this standard by the selected "signaling" separately.
The main advantages of this function are, first of all, that it reduces the number of key fobs used to control the functions of t...he car, and at the same time allows you to use all the "chips" of standard key fobs / keys that were originally provided by the manufacturer. In addition, branded key fobs and keys are purely subjectively liked by many drivers due to the presence of symbols of a particular car brand.

— Management of windows. Possibility to control the windows of the car through the car alarm. Thanks to this function, the driver can raise and lower the windows of the car remotely, from a key fob or other control device. This feature can be useful, for example, if the car is already closed, but the windows are not fully raised: instead of disarming the car and getting to the power window control buttons, you can simply give a command from the key fob.

— Management of the opening of the boot. The ability to control the opening of the boot of the car through a car alarm, from a key fob or other control device. This function, usually, allows you to open and close the boot without disarming the doors (and other areas of the car) and without entering the passenger compartment. This is more convenient, and sometimes even safer, than working with the boot in the usual way.

— Locking doors when driving. Possibility of automatic locking of car doors at the beginning of the movement. This feature reduces the risk of a car being seized by force when intruders get into the passenger compartment by simply opening unlocked doors — for example, while stopping at a traffic light. Of course, the central lock can be closed from the driver's seat and manually; however, you can forget about it, while automatic closing works without driver intervention.

— Panic mode. The presence of the "Panic" mode in the alarm system allows the driver to manually turn on the alarm — with a siren, light signals, engine blocking, etc. This feature can be useful if the driver sees suspicious people at his car — in order to frighten off potential hijackers — as well as in other situations when you need to draw the attention of others to the car. In addition, in the absence of the "Search for a car" function (see below), a short-term activation of the "Panic" mode can play its role.

— Function "Polite backlight". Alarms with the function of "polite lighting" are able to control the interior lighting, providing the driver and passengers with additional comfort. For example, when the doors are opened, the lighting can turn on, facilitating placement and orientation in the cabin, and when you start moving and close the doors with the ignition off, it can go out. Turning the light on and off is often done smoothly, avoiding abrupt transitions and making it easier for the eyes to get used to it.

— "Take me home" feature. With this function, the alarm can control the headlights so that they (when the engine is turned off) do not turn off immediately, but after some time after pressing the switch and closing the door. Thus, you can use car headlights to illuminate at night — for example, if you need to walk from the car to the entrance in a dark courtyard on uneven asphalt. The time for turning off the “seeing off” headlights is most often about half a minute — this, usually, is quite enough for the purposes described.

— Function "Search vehicle". This function consists in the fact that, at the command from the key fob, the alarm system gives several short signals (light or sound, and in silent security mode — only light), signaling the driver about the location of the car or motorcycle. This can be useful, for example, in a large parking lot of a hypermarket or an entertainment complex, where the vehicle can get lost among other cars, and searching for it “manually” (especially if you need to carry purchases or roll a cart at this time) can be quite tedious.

— Hands Free function (label). This function allows the driver to control the alarm without using the key fob. A special tag is responsible for managing the operating mode, which the driver needs to carry with him, and a sensor system that responds to the approach and distance of the tag. Thus, when a person with a tag moves away from the car at a certain distance, the alarm is automatically armed, and, having noticed the appearance of a tag within the range of the sensors, it is removed. This format of work allows the driver to keep his hands free and not be distracted by the key fob; in addition, communication between the system and the tag is minimal, making scanning nearly impossible.

— Autostart on the voltage of the onboard network. Possibility of using an alarm to automatically start the engine in case of a significant drop in battery voltage. This situation may arise, in particular, when the car is idle for a long time, especially in cold weather. A dead battery is not only fraught with problems when starting a car: car alarms are often powered from it, so when the charge is exhausted, the car can be left unguarded. To avoid this, this possibility is provided: having fixed a voltage drop close to critical, the alarm starts the engine for a while, recharging the battery from the auto generator and preventing the described troubles. It should be noted that the use of this function is associated with certain restrictions and precautions; for more details about them, see above, in the paragraph “Autostart by temperature”.

— Function "call the driver". This feature allows a person at or inside the car to signal a call to the driver's key fob. Note that the call button is most often installed in the cabin, based on passengers; however, an external location may also be provided, allowing the driver to be called even with the car closed. In the latter case, the installation location of the call sensor is usually marked with a sticker with the appropriate inscription, for example, “Knock three times to call the driver”; and the call method is chosen in such a way that the alarm system can clearly distinguish it from an attempted opening or accidental impact on the car. However, this feature is only found on models with two-way communication (see "Communication Type"). In this case, we are talking about a separate call signal, and not about a general alarm signal, which allows the driver to more accurately assess the situation (and saves his nerves). “Calling the driver” can come in handy, for example, in a situation where the passenger remaining in the car felt unwell, or if the car had to be put in such a way that it blocks the exit of other vehicles. In the latter case, conscientious drivers leave a note with a mobile phone number on the glass, but with this function, you can do without a note — the main thing is that the range of the key fob is enough.

— Bluetooth Smart. This function allows the user to use a smartphone with a special application as a key fob to access the car. At the same time, in accordance with the name, communication is carried out via Bluetooth, due to which such authentication works even in the absence of mobile communication (for example, in an underground garage). The convenience of such alarm control is obvious: you do not need to carry an additional item (keychain or tag) with you, and the probability of forgetting your smartphone somewhere is much lower than the probability of not taking the same keychain with you. At the same time, the probability of interception of the control signal, according to the manufacturers, is practically zero. And in some models, owner authentication and disarming can be carried out completely automatically when the smartphone approaches a certain distance. Other functions (such as transmission of diagnostic data) can also be implemented via Bluetooth Smart, depending on the model. The main disadvantage is that Bluetooth Smart alarms are very expensive. In addition, this technology is far from compatible with every smartphone, this point needs to be specified separately.

— Diagnostics of malfunctions. The ability to use alarms to diagnose various failures and malfunctions. In different models, the implementation and capabilities of this function may be different. Most often, this function involves at least self-diagnosis: the alarm “interrogates” the sensors with service signals and, if one of them fails, notifies the user about this. However, more extensive possibilities may also be provided — such as obtaining data from the car's own sensors (for example, about a decrease or complete disappearance of battery voltage). This not only allows you to monitor the technical condition of the car, but also provides additional security — for example, a decrease in the level of gasoline in the tank may be a sign that it is being drained.

Features for automatic start and shutdown of the engine, provided in the alarm. In some cases, using automation is much easier, more convenient, and even more reliable than starting and stopping the engine manually.

— Autostart by timer. Alarms with this function are able to automatically start the car engine at a certain time set by the driver. This feature allows, in particular, to provide additional comfort and save time on warming up: since the owner does not need to be in the car to start the engine, he can come later, get into an already warmed up car and drive right away.

— Autostart by temperature. The ability to use an alarm to automatically start the engine for warming up — in the event that its temperature drops below certain values. This function is intended for the cold season, when the machine has to stand outdoors for a long time (for example, all night). Starting a cold, and even more “frozen” engine is associated with a number of problems: the oil becomes thicker, and the battery can “sit down” and produce a weaker current than expected. To avoid such problems, some car alarms are equipped with an auto start function based on temperature: when the engine temperature drops below a certain level, the system automatically starts it to warm up. This ensures that the temperature is maintained sufficient for a comfortable start of the engine at any time. On the other hand, fuel...is spent on regular warming up of the engine, and in enclosed spaces and other places where exhaust gases are undesirable (and even dangerous), this function is poorly applicable. Thus, most alarms with this feature have limitations related to fuel economy — for example, starting less than a certain number of times during one idle time, or the maximum engine warm-up time.

— According to the voltage of the on-board network. Automatic start of the car engine in the event of a voltage drop on the on-board network (in fact, the car battery) to a certain level. By using this function, you can avoid a decrease in battery charge and related troubles — including not only starting “with a pusher” or “lighting up”, but also completely turning off the alarm (if it does not have an autonomous power supply). Of course, the operation of autorun requires additional fuel costs, but usually such alarms have a number of restrictions aimed at minimizing such costs. But when parking a car in a closed room, this function should be used with caution — it requires good ventilation, otherwise the periodic engine start will lead to the accumulation of exhaust gases.

— Turbo timer mode. Possibility of operation of the alarm as a shutdown timer for an engine equipped with a turbocharging system. During driving, the turbocharger can reach high temperatures, and the oil circulation necessary for effective cooling is ensured by the operation of the engine. If you immediately turn off the car after driving, the heated compressor will actually lose the main cooling system, which can lead to damage and even failure. Therefore, the rules for operating turbocharged engines prescribe, after stopping, to allow the engine to idle for a while to cool the turbocharging system. However, the driver does not always have time to wait for the compressor to cool down. The turbo timer "simplifies life" for drivers of turbocharged cars: it keeps the engine running for some time after the ignition key is removed, after which it automatically turns off the engine. This eliminates the need to wait without removing the key from the ignition and manually control the idling time.

— Webasto support. Car alarm support for Webasto equipment, more precisely, the proprietary W-bus protocol. Webasto is known primarily as a manufacturer of starting heaters for cars, however, in addition to this, the company produces many other components, mainly for “climatic” purposes — air conditioners, sunroofs, etc. Accordingly, Webasto support allows you to connect an alarm to equipment under the W-bus and control this equipment through it. Note that W-bus controllers are also available separately, but it is usually easier and more reliable to buy a compatible signaling right away. — Support of the signaling of the Start/Stop function. This function is mainly intended to give the driver the ability to start the engine without using a key, simply by pressing a special button. At the same time, some models are designed for installation in a car where such a button was originally provided, and we are only talking about compatibility with a keyless start system; others are equipped with their own button and can even be installed in cars that were initially started only with a key.
In addition, models with the "Start / Stop" function can have the function of remote engine start on command from the key fob. This can be useful, for example, to save time on warming up the car before driving in cold weather: you can start the engine without leaving your home, and then get into an already warm car.

— Automatic transmission support. Signaling compatibility with automatic transmissions.
Such systems are structurally more complex than traditional mechanical boxes, they are closely related to the electronics and controls of the car. Therefore, for the correct operation of the autorun functions on a car with automatic transmission, it is necessary that this type of transmission is initially supported by the alarm system. If the “signaling” covers only locks and other functions that are not actually related to the engine, this feature is not mandatory.

— Support for diesel engines. This feature is indicated for car alarms that have a specialized mode for starting diesel engines. One of the differences between such engines and gasoline engines is that they use the so-called. glow plugs. For normal operation of the diesel engine, it is necessary that such candles warm up to operating temperature; heating starts immediately when the ignition is switched on, but it takes time. These moments are taken into account in the "diesel" mode: the alarm first turns on the ignition, and gives the start command only after the candle warm-up indicator goes out.

The number of tags provided in the delivery set of keyless alarms (see "Type of connection"). For more information on tags and their purpose, see "Functions - Hands Free Function (Tag) ". And the presence of several tags in the kit allows you to provide access to the car to several people at the same time - for example, if the driver and passenger need to go about their own business, and it is not known who will return to the car earlier, you can give the passenger a second tag. In addition, a spare can be useful in case of loss or damage to the main tag.

Most modern keyless alarms with the appropriate capabilities are equipped with two or more tags. This is considered the best option given that it is not often that there is a real need to distribute additional tags, but a margin is highly desirable in any case.
