{"product_id":"system-sensor-4wtr-b-photoelectric-smoke-detector","title":"System Sensor 4WTR-B Photoelectric Smoke Detector","description":"The System Sensor 4WTR-B 4-Wire Photoelectric i3 Series Smoke Detector Thermal Sensor will improve the efficiency and reliability of your fire detection system. This innovative smoke detector combines photoelectric detecting technology with a heat sensor and Form C relay to deliver precise fire detection. Its cutting-edge features guarantee a quick and precise reaction to possible fire dangers, making it a crucial component of any safety system.\n\nInstallation is made seamless with the System Sensor 4WTR-B's user-friendly design. The plug-in mechanism and installer-friendly base simplify the setup process, accommodating a range of mounting options. The base not only ensures secure installation but also provides ample space for pre-wiring, streamlining the process further. With its Stop-Drop N Lock action, connecting the detector to its base becomes hassle-free, guaranteeing a reliable and durable connection.\n\nTo minimize the likelihood of nuisance alarms, the System Sensor 4WTR-B employs advanced algorithms, including drift compensation and smoothing capabilities. These features effectively counteract factors such as RF interference and dust accumulation, reducing both short-term and long-term false alarms. With red and green LEDs, the detector offers clear local status indication for power-up, standby, alarm, maintenance, and freeze trouble issues. The inclusion of an 85 dB sounder ensures that alarm signals are unmistakably clear. Moreover, the Form C relay and isolated thermal sensor provide flexibility in differentiating between local and general alarms. This level of customization ensures tailored responses to varying scenarios, enhancing the overall effectiveness of your fire detection system.","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":53031482556736,"sku":"4WTR-B","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/2274\/8736\/files\/4WTR_B_0.jpg?v=1786994236","url":"https:\/\/store.greenwaveelectronics.com\/products\/system-sensor-4wtr-b-photoelectric-smoke-detector","provider":"Green Wave Electronics","version":"1.0","type":"link"}
