It provides backup power to electric door operators and control units in commercial buildings, keeping automatic doors functional during mains failure. Dimensions are 114.00 × 49.70 × 28.60mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTürsteuerung backup power rail:\u003c\/strong\u003e\n    Dorma automatic door controllers run a dedicated 19.2V backup circuit that activates the moment mains supply drops. This battery sits on that circuit and must match the voltage rail exactly — even a slight mismatch causes the backup relay to reject the pack and fall back to fail-safe mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and simulated mains-fail events. The BMS held cutoff correctly at cell floor voltage and recovered without fault codes on reconnection to the charge circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install power-fail test:\u003c\/strong\u003e\n    After fitting this battery, manually trigger a power-fail simulation during a low-traffic period. Automatic door backup batteries must complete a full open-and-close cycle under load before the installation is considered verified — charge for a full 24 hours first.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAutomatic door not completing full open cycle on battery backup\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the Türsteuerung switches to backup power, it draws a sharp current spike to drive the door motor through a full open cycle. A degraded or under-charged Ni-MH pack sags below the controller's minimum operating voltage during that spike. The controller then cuts the motor mid-cycle as a protective response — the door stops partway open. A new pack must be fully charged before testing; target charge voltage is 22.8V at the battery terminals before load is applied.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDoor controller losing stored programming after a power outage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDorma Türsteuerung units store open\/close timing, force limits, and hold-open durations in volatile RAM. That RAM is kept alive by the backup battery even when mains power is absent. If the battery has discharged below 15V, RAM loses power and all programming reverts to factory defaults on mains restoration. Reprogramming is straightforward, but the root fix is replacing the depleted battery and running a charge cycle immediately after fitting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315054149722,"sku":"BWCS-RST170AF-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315054182490,"sku":"BWCS-RST170AF-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315054215258,"sku":"BWCS-RST170AF-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RST170AF-1.webp?v=1777949432","url":"https:\/\/batteryweb.com\/products\/dorma-tursteuerung-replacement-battery-192v-1600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
