The DRTB-T-2 threshold board adds digital rate-of-rise detection logic to the CTM module, enabling the system to alarm when the cable temperature rises at a rate exceeding the set threshold, independent of whether the fixed-temperature set point has been reached. This expands the detection envelope for fast-developing fire scenarios in cable trays, conveyor systems, and transformer rooms. The DRTB-T-2 is a plug-in accessory for CTM-530 Series modules; confirm compatibility with your specific CTM model before ordering.\u003c\/p\u003e\n\u003cp\u003eVerify panel\/device family compatibility before ordering.\u003c\/p\u003e","brand":"Protectowire","offers":[{"title":"Default Title","offer_id":52004362617125,"sku":"DRTB-T-2","price":105.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/7648\/4645\/files\/protectowire-fire-alarms-default-title-protectowire-drtb-t-2-terminal-block-with-integrated-test-jack-38677627830496.png?v=1771296196","url":"https:\/\/fastalarmdistribution.com\/products\/protectowire-drtb-t-2","provider":"Fast Alarm Distribution","version":"1.0","type":"link"}
