It represents a combination of a smoke detector with an adapter system, whose measuring 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 via the detector chamber back into the air duct. Upon detection of smoke, the detector reacts immediately and triggers an alarm. Over time, the detector gets dirty. 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 from 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 demonstrate functionality, the device is equipped with electronic airflow monitoring, which illuminates a blue LED when \u0026lt; 1 m\/s. The fault LED illuminates if the smoke detector or the electronics are defective, or if the smoke detector is missing. The smoke alarm must be reset with the reset button. The function test is also possible with the same button. Actuation works like a smoke alarm. The same function is also achieved upon 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":52584593457499,"sku":"52008","price":593.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/0742\/7931\/files\/52001-24-scaled_2b84a0b8-27ea-4273-8ed0-771edc4255e7.jpg?v=1773400380","url":"https:\/\/it-at.de\/en\/products\/krm-x-2-mod-0-16","provider":"IT-AT","version":"1.0","type":"link"}
