The wireless magnetic door and window sensor for alarm systems PNI-HS002LR is an indispensable security element that detects any attempted break-in before an uninvited guest even enters the building. With its help, you will raise the level of security of your property to a completely new level without wasting your assets.\u003cbr\u003e This high-quality magnetic sensor works on the simple but extremely effective principle of a magnetic switch (reed switch). When a door or window is opened by more than 1.5 cm, the magnetic contact is broken. The sensor immediately sends a wireless signal to your alarm control panel, which triggers a loud alarm or sends you an instant notification on your smartphone. Forget about complicated cable laying, ducting and time-consuming drilling of holes - advanced wireless technology allows for a clean, fast and aesthetic installation that will not spoil the look of your home.\u003cbr\u003e Why choose the PNI-HS002LR wireless magnetic sensor?\u003cbr\u003e The safety of your property and family is always a top priority. This sensor is designed with maximum reliability, long life and extreme ease of use in mind. It combines advanced detection technology and extremely economical operation, providing long-lasting protection without the need for constant maintenance or frequent battery replacement. It is suitable for residential buildings as well as commercial premises, warehouses or weekend cottages.\u003cbr\u003e Key features and technical advantages\u003cbr\u003e\u003cbr\u003e Immediate action in milliseconds: The sensor reacts the moment the door or window opens by more than 1.5 cm and immediately sends an opening\/closing code to your central unit.\u003cbr\u003e Wireless freedom (433 MHz frequency): With a signal transmission range of up to 100 meters in open space, you can also install the sensor on more distant windows, doors or auxiliary buildings without worrying about signal strength.\u003cbr\u003e High intelligence and sensitivity: The built-in advanced microprocessor chip and dual infrared detection element effectively prevent false alarms and ensure exceptional operating accuracy.\u003cbr\u003e Easy installation without cables: Since the sensor works completely wirelessly, there are no cables, wires or drilling into walls required. Installation is quick, clean and suitable for any DIYer.\u003cbr\u003e Compact and discreet design: With its dimensions of only 67 x 40 x 12 mm and elegant white housing, the sensor blends seamlessly into any style of joinery and does not stand out.\u003cbr\u003e Versatile compatibility: Perfectly adapted for the PNI CM002 wireless alarm system and other compatible systems operating at a frequency of 433 MHz.\u003cbr\u003e\u003cbr\u003e Main benefits for the user\u003cbr\u003e By purchasing the PNI-HS002LR sensor, you will finally have a peaceful sleep. Whether you are at work, on a long trip or sleeping carefree on the upper floor, this small but extremely effective device will constantly watch over all the entrances to your home. The device is made of robust and high-quality materials that ensure a long service life and stable operation in a wide temperature range from -10 °C to +50 °C.\u003cbr\u003e The sensor easily adapts to different types of doors and windows (wooden, PVC, aluminum), allowing you to use it throughout your entire facility. It is powered by an efficient 3V CR2450 battery, which is included in the package. Thanks to optimized energy consumption and smart power management, the battery provides long months of uninterrupted operation without the need for replacement.\u003cbr\u003e Technical specifications and features\u003cbr\u003e See detailed technical data below, confirming the quality, reliability and versatility of this wireless magnetic sensor:\u003cbr\u003e\u003cbr\u003e Model \/ SKU: PNI-HS002LR\u003cbr\u003e Alarm distance (detection): Less than 1.5 cm (when the distance between the magnets increases above this limit, an alarm is triggered)\u003cbr\u003e Power supply: 1 x CR2450 3V battery (battery already included in the package for immediate use)\u003cbr\u003e Operating frequency: 433 MHz\u003cbr\u003e Signal transmission distance: Up to 100 m in open space (in buildings, depending on obstacles and walls)\u003cbr\u003e Technology: Dual infrared detector element and advanced microprocessor chip\u003cbr\u003e Functionality: Sending codes for opening and closing doors\/windows to the alarm control panel\u003cbr\u003e Operating temperature range: -10 °C to +50 °C (suitable for indoor use and protected passages)\u003cbr\u003e Dimensions: 67 x 40 x 12 mm\u003cbr\u003e Weight: 280 g (with battery included)\u003cbr\u003e Compatibility: Suitable for the PNI CM002 wireless alarm system and other compatible systems at a frequency of 433 MHz\u003cbr\u003e\u003cbr\u003e Easy installation in just a few minutes\u003cbr\u003e You don't need expensive security technicians or experts to install this sensor. The sensor consists of two parts: a larger transmitter (which houses the battery and electronics) and a smaller magnet. Simply attach the transmitter to the fixed part (door or window frame), and the magnet to the movable part (door or window leaf). You can use the included double-sided adhesive tape or small screws to attach it. It is only important that the distance between the two parts is less than 1.5 cm when closed. When the system is activated, your safety net is immediately established.\u003cbr\u003e Frequently Asked Questions (FAQ)\u003cbr\u003e How far from the alarm control panel can I install this magnetic sensor?\u003cbr\u003e The PNI-HS002LR wireless sensor boasts an excellent signal transmission range of up to 100 meters in open space. In enclosed spaces with walls, doors and other obstacles, this distance may be slightly reduced, but it easily covers average residential buildings, larger apartments and standard business premises.\u003cbr\u003e What kind of battery does the sensor use and do I need to buy it separately?\u003cbr\u003e The sensor uses a high-capacity CR2450 3V button battery. The big advantage is that the battery is already included in the package, which means that the device is ready for immediate installation and use. Thanks to the advanced microprocessor and extremely low power consumption, the battery ensures long-lasting and stable operation.\u003cbr\u003e Is this sensor suitable for mounting on metal or PVC doors?\u003cbr\u003e Yes, thanks to its compact design, low weight and universal magnetic field operation, the sensor is extremely flexible.

The markings on the housings should face each other.\u003cbr\u003e • The distance between the magnet and the sensor in the closed state must not exceed 10–15 mm (depending on the model).\u003cbr\u003e • Performance testing:\u003cbr\u003e • Open the window or door and check whether the LED on the sensor lights up and whether the control panel detects the opening.\u003cbr\u003e\u003cbr\u003e Useful tips for work:\u003cbr\u003e • Correct placement: Always place the transmitter on a fixed part (frame) and the magnet on a movable part (sash). This prevents vibrations and strong impacts when closing, which could damage the electronics.\u003cbr\u003e • Be careful with metal surfaces: If you are mounting the sensor on metal or aluminum doors\/windows, use caution when using magnetic sensors, as metal can reduce the range of the magnet or weaken the wireless signal. In this case, use plastic spacers to keep the sensor away from the metal.\u003cbr\u003e • Regular testing: At least once every few months, test the sensor's operation and battery status via the mobile app or alarm control panel.\u003cbr\u003e • Low battery indicator: Most modern sensors will alert you to low battery levels via an LED indicator or app. Replace the battery immediately upon notification.\u003cbr\u003e\u003cbr\u003e Warnings:\u003cbr\u003e • For indoor use only: The sensor (unless specifically marked as waterproof) is not intended for outdoor use. Moisture, rain and extreme temperatures can damage the electronics.\u003cbr\u003e • Signal range: Before final mounting with adhesive tape, check whether the wireless signal between the sensor and the control panel at the selected location is strong and stable enough (especially through thick load-bearing walls).\u003cbr\u003e • Battery safety: Keep batteries out of the reach of children. Dispose of used batteries in designated recycling containers.\u003cbr\u003e • Do not cover the sensor: Do not paint or cover the sensor with metal decorations, as this may prevent the radio signal from being transmitted.\u003cbr\u003e\u003cbr\u003e\u003ch2\u003eIt is important to know\u003c\/h2\u003e\u003cp\u003e This magnetic sensor is suitable for anyone who wants to expand their alarm system to control doors or windows - especially where you already have a smart security center.
