Usage
The Cisa TEKNO DUO double cylinder 30/45 is designed for securing entrance doors in residential, commercial, and industrial settings where high resistance to unauthorized access and advanced key control are required.
Advantages
- High protection against bumping with the patented BKP (Bump Key Power) device
- Enhanced anti-picking features thanks to special-shaped counter pins and a complex pin system
- Certified drill resistance with hardened steel elements in critical areas
- Durable construction with a brass body and self-lubricating clutch-type cam for long-lasting performance
- Key duplication is strictly controlled via security card authorization, reducing risk of unauthorized copies
Specifications
- Design: Double cylinder profile made from nickel-plated brass; features cemented steel pins, variable shape hardened drivers, phosphor bronze and steel springs; clutch-type cam enables operation from both sides even if one key remains inserted.
- Security & Standards: Complies with EN1303:2005 standards (key-related security grade: 6; attack resistance grade: 2); includes BKP patent for bumping protection[1][5]. Keys protected by patent EP1867810B1.
- Pins & Control: Features a complex system of up to twelve elements—6 active pins, 4 passive pins, plus two control side pins—for increased pick resistance and over 100,000 effective differs[3][1]. Supplied with three reversible flat keys in nickel-plated brass and ergonomic grip.
- Differentiation: Security card required for duplicating keys. Cam DIN format enables compatibility across most European mortise locks. Dimensions: Total length approximately 75 mm (30/45 mm), weight about 0.225 kg[1]. Emergency function permits opening from either side even if a key is already inserted on the opposite side.
How it works
The double cylinder operates by inserting the authorized key into either side; internal pin tumblers recognize the correct pattern to engage or release the locking cam. The clutch mechanism allows operation from both sides simultaneously—even when one key remains inside—supporting emergency situations while maintaining strict access control through patented keys.[1][3]
