It represents 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. The multi-chamber measuring tube in the air duct transports the air within the air duct along the entire length of the tube through the detector chamber back into the air duct. If smoke is detected, 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 triggers and signals this by flashing. If the detector is not replaced, a smoke alarm will occur at 99% contamination. The degree of contamination is signaled on a two-line LED display; at \u0026gt; 70%, it flashes and the \"dirt\" relay drops out. To prove functionality, the device is equipped with an electronic airflow monitoring system, which illuminates a blue LED at \u0026lt; 1 m\/s. The fault LED illuminates if the smoke detector or electronics are defective, as well as if the smoke detector is missing. The smoke alarm must be unlocked with the reset button. The same button can also be used for the functional test. Activating it acts like a smoke alarm. Furthermore, the same function is achieved with a restart or by opening the bridge between terminals 9 and 10 (remote unlock).\u003c\/p\u003e","brand":"IT-AT","offers":[{"title":"Default Title","offer_id":52584594932059,"sku":"52004","price":575.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/0742\/7931\/files\/52001-24-scaled_63d05853-3902-4b6b-955e-335194cceb2a.jpg?v=1773400398","url":"https:\/\/it-at.de\/en\/products\/krm-x-1-0-6","provider":"IT-AT","version":"1.0","type":"link"}
