It is a combination of a smoke detector with an adapter system whose sampling tube and housing have been specially adapted for optimal airflow through the smoke detector.\u003c\/p\u003e\n\u003cp\u003eThe air duct sampling tube transports the air within the air duct along the entire length of the tube through the detector chamber back into the air duct. Upon detection of smoke, the detector reacts immediately and triggers an alarm. Over time, the detector becomes contaminated. Due to the alarm threshold tracking, the sensitivity remains the same until total contamination. From 70% contamination, the detector signals dirt. If the detector is not replaced, a smoke alarm will be triggered from 99% contamination. The contamination level is signaled on a two-line LED display, which flashes at \u0026gt; 70%.\u003c\/p\u003e\n\u003cp\u003eTo monitor functionality, the device is equipped with an electronic airflow monitoring system, which illuminates a blue LED at \u0026lt; 1 m\/s. The fault LED lights up if the smoke detector or electronics are defective, or if the smoke detector is missing. The smoke alarm or a fault must be reset with the reset button. The functional test is also possible with the same button.\u003c\/p\u003e\n\u003cp\u003eActuation acts like a smoke alarm. Furthermore, the same function is achieved on restart if the bridge between terminals 9 and 10 is opened (remote unlocking).\u003c\/p\u003e\n","brand":"IT-AT","offers":[{"title":"Default Title","offer_id":52584591720795,"sku":"52014","price":962.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/0742\/7931\/files\/52001-24-scaled_5400e4fa-a127-4dca-916c-07a0ce88d8a5.jpg?v=1773400354","url":"https:\/\/it-at.de\/en\/products\/krm-x-1-mod-dz-0-16","provider":"IT-AT","version":"1.0","type":"link"}
