{"product_id":"system-sensor-dnrw-innovairflex-duct-detector","title":"System Sensor DNRW- InnovairFlex Duct Detector","description":"The System Sensor DNRW InnovairFlex Duct Detector is a watertight intelligent non-relay photoelectric duct smoke detector housing designed for smoke detection in air handling and HVAC duct systems. Its flexible housing accommodates both rectangular and square duct configurations and is suitable for demanding commercial fire safety applications. The DNRW is NEMA 4 rated for enhanced protection against water and environmental exposure. It supports air duct velocities from 100 to 4,000 ft\/min and can provide a trouble signal if the sensor cover is removed or improperly installed. Local testing is supported through a magnetic switch, while remote testing can be performed with a compatible remote test station. The housing requires a compatible photoelectric smoke detector head, which is sold separately.","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":53117065888064,"sku":"DNRW","price":177.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/2274\/8736\/files\/DNRW_0_N.jpg?v=1788878151","url":"https:\/\/store.greenwaveelectronics.com\/products\/system-sensor-dnrw-innovairflex-duct-detector","provider":"Green Wave Electronics","version":"1.0","type":"link"}
