The XSD200 is a wireless smoke and heat alarm combined in one device, sharing the features of its smaller sibling, the XSD100. Installation is done using a certified gel adhesive pad, making the device suitable for kitchens and providing insect protection. It is powered by two built-in batteries that last for at least 10 years, eliminating the need for regular battery replacements. As a highly advanced wireless smoke alarm, the XSD200 is the ideal solution for larger apartments and houses, allowing for connectivity across multiple floors. This means that the alarm is not only triggered by the device nearest to the fire, but all residents are promptly and reliably alerted through all connected XSD200 units in the wireless network, loudly and clearly. Up to 15 XSD200 devices can be quickly and easily grouped together. Additionally, the XSD200 can also be connected to the PX-AR, seamlessly integrating it into an online Wi-Fi smoke detector system.
