When the roller shutter door is opened while the system is armed, the sensor transmits a trigger signal to the Helio main panel, which activates the configured alarm response.\u003c\/p\u003e\u003cp\u003eThe sensor uses a reed-and-magnet design: the transmitter and reed part attach to the shutter frame, while the magnetic part attaches to the moving door surface. A 290 mm connecting line allows for flexible positioning. Energy saving mode and RF supervision keep the power draw low, while the main panel sends an SMS to the user when battery replacement is needed. Tamper protection triggers an alert if the unit is removed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned for roller shutter doors — reed-and-magnet contact detection\u003c\/li\u003e\n\u003cli\u003eTriggers alarm when shutter opens under armed status\u003c\/li\u003e\n\u003cli\u003eRF supervision for continuous wireless link monitoring\u003c\/li\u003e\n\u003cli\u003eTamper protection\u003c\/li\u003e\n\u003cli\u003eLow battery SMS notification from the main panel\u003c\/li\u003e\n\u003cli\u003eWireless transmission at 433.92 MHz, up to 1000 m without obstacle\u003c\/li\u003e\n\u003cli\u003ePowered by 1 × CR123A (3 V) battery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDedicated roller shutter design uses a 170 mm magnetic part that runs the full vertical width of a standard shutter door contact zone\u003c\/li\u003e\n\u003cli\u003eRF supervision actively monitors the wireless link, flagging any loss of contact with the panel before it creates a coverage gap\u003c\/li\u003e\n\u003cli\u003eTamper protection means physical removal of the sensor triggers an alarm, deterring disabling by intruders\u003c\/li\u003e\n\u003cli\u003eAt only 169 g without the battery, the complete assembly is lightweight and does not place load on the shutter mechanism\u003c\/li\u003e\n\u003cli\u003eThe 290 mm connecting line provides mounting flexibility where the transmitter and reed part cannot be collocated directly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e DGDH1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Voltage:\u003c\/strong\u003e DC 3 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 1 × CR123A (3 V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Current:\u003c\/strong\u003e ≤100 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby Current:\u003c\/strong\u003e ≤15 μA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission Distance:\u003c\/strong\u003e 1000 m (without obstacle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission Frequency:\u003c\/strong\u003e 433.92 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Supervision:\u003c\/strong\u003e Supported\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTamper Protection:\u003c\/strong\u003e Supported\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Temperature:\u003c\/strong\u003e -10°C to +50°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHumidity:\u003c\/strong\u003e ≤90% rh (non-condensing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 169 g (without battery); 185 g (with battery)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReed Part Dimensions:\u003c\/strong\u003e 38×15×10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic Part Dimensions:\u003c\/strong\u003e 15×170×15 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter Dimensions:\u003c\/strong\u003e 84×26×22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting Line Length:\u003c\/strong\u003e 290 mm (L×W×H ±0.1 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThe long 170 mm magnetic strip accommodates the wide contact gap geometry of roller shutter doors, which standard door sensors cannot cover\u003c\/li\u003e\n\u003cli\u003eOne CR123A battery powers the unit; the panel sends an SMS replacement reminder so the battery is never silently depleted\u003c\/li\u003e\n\u003cli\u003eThe slim transmitter (84×26×22 mm) attaches to a shutter frame without obstructing the door travel or surrounding structure\u003c\/li\u003e\n\u003cli\u003ePart of the Helio ecosystem: pairs with the same panel as motion sensors, smoke detectors, and the outdoor siren\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Other","offers":[{"title":"Default Title","offer_id":56579035857278,"sku":"225024","price":30.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675205943678.webp?v=1779616870","url":"https:\/\/lynk.gr\/en-gb\/products\/other-dinsafer-helio-wireless-roller-shutter-door-contact-se","provider":"Lynk.gr","version":"1.0","type":"link"}
