The fault LED illuminates if the smoke detector or electronics are defective, or if the smoke detector is missing. The smoke alarm must be unlocked with the reset button. The same button also allows for a function test. Actuating it has the same effect as a smoke alarm. Furthermore, the same function is achieved by restarting or by opening the bridge between terminals 9 and 10 (remote unlocking).\u003c\/p\u003e","brand":"IT-AT","offers":[{"title":"Default Title","offer_id":52584595259739,"sku":"52003","price":605.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/0742\/7931\/files\/52001-24-scaled_c57e4408-3eb6-49e6-9a84-ee80421ae2c6.jpg?v=1773400403"},{"product_id":"krm-x-1-0-16","title":"KRM-X-1 0.16","description":"\u003cp\u003eOppermann KRM-X-1 0.16\u003cbr\u003e230 V AC, for controlling fans and for ventilation monitoring\u003c\/p\u003e\u003cp\u003eincl. sampling tube LKR-X 0.16 m\u003c\/p\u003e\u003cp\u003eVdS approval (G219046\/G219053)\u003cbr\u003ePatented single-tube air measurement system\u003cbr\u003ePollution display in % and message at 70 %\u003cbr\u003eElectronic air flow control\u003cbr\u003eReset button in housing, operable from outside\u003cbr\u003eRemote reset option via terminals\u003cbr\u003eLong service life, alarm threshold tracking\u003cbr\u003eRS485 bus interface (only -MOD\/ -BAC)\u003cbr\u003eTechnical data\u003c\/p\u003e\u003cp\u003eDetector type: scattered light RM 3.3-X (ALN-E)\u003cbr\u003ePower supply KRM-X-1\/KRM-X-1-MOD\/KRM-X-1-BAC:\u003cbr\u003e230 V AC ± 10 %, 50\/60 Hz\u003cbr\u003ePower supply KRM-X-2\/KRM-X-2-MOD\/KRM-X-2-BAC:\u003cbr\u003e24 V AC (16 ? 27.6 V AC) or 24 V DC (21.6 ? 27.6 V DC)\u003cbr\u003eRated current: KRM-X-1 \/KRM-X-1-MOD\/KRM-X-1-BAC: 30 mA\u003cbr\u003eKRM-X-2\/KRM-X-2-MOD\/KRM-X-2-BAC: 120 mA\u003cbr\u003eRelay outputs: potential-free\u003cbr\u003eAlarm relay latched: 1 changeover contact, 8 A, 250 V AC or 24 V DC\u003cbr\u003e1 N.C. contact, 8 A, 250 V AC or 24 V DC\u003cbr\u003ePollution relay: 1 N.C. contact, 6 A, 250 V AC or 24 V DC\u003cbr\u003eOperating temperature: -20 °C - +50 °C\u003cbr\u003ePermissible flow: 1 - 20 m\/s\u003cbr\u003ePermissible humidity: 10 - 95 % non-condensing\u003cbr\u003eProtection class: IP 65\u003cbr\u003eApprovals\/tests: VdS approval G219046, G219053, DIN EN 54-27\u003cbr\u003eLED Display: Pollution level %, flashes \u0026gt; 70 %\u003cbr\u003eLED in housing: green operation, blue missing air flow, yellow fault, electronics, smoke detector defective red smoke alarm, incl. pollution \u0026gt; 99 %, flashes when attempting to unlock if the detector chamber is not yet empty\u003cbr\u003eHousing: ABS\u003cbr\u003eAir measuring tube: aluminium\/plastic\u003cbr\u003eShortest length 160 mm\u003cbr\u003eStandard length 600 mm\u003cbr\u003eMaximum length 3009 mm\u003cbr\u003eDimensions: approx. 271 x 172 x 85 mm (L x W x H)\u003cbr\u003eCable gland: 3 x M16\u003c\/p\u003e\u003cp\u003eFunction\u003c\/p\u003e\u003cp\u003eThe KRM-X duct smoke detector was developed for smoke detection in ventilation ducts. 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. The multi-chamber sampling 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 detecting smoke, the detector reacts immediately and triggers an alarm. Over time, the detector becomes 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 signalled on a two-line LED display; at \u0026gt; 70 % this flashes and the \"dirt\" relay drops out. To demonstrate functionality, the device is equipped with electronic airflow monitoring, which illuminates a blue LED if the flow is \u0026lt; 1 m\/s. The fault LED illuminates if the smoke detector or electronics are defective or if the smoke detector is missing. The smoke alarm must be reset using the reset button. The function test can also be carried out with the same button. Activation acts like a smoke alarm. Furthermore, the same function is achieved by restarting or by opening the bridge between terminals 9 and 10 (remote unlocking)\u003c\/p\u003e","brand":"IT-AT","offers":[{"title":"Default Title","offer_id":52584595521883,"sku":"52001","price":569.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/0742\/7931\/files\/52001-24-scaled_50f4b223-bcf1-4393-98c4-c901f34030b8.jpg?v=1773400407"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/0742\/7931\/collections\/Rauchmelder.jpg?v=1778781648","url":"https:\/\/it-at.de\/en\/collections\/rauchmelder.oembed","provider":"IT-AT","version":"1.0","type":"link"}
