Cylinder electromechanical lock CISA 15535

The CISA 15535 cylinder electromechanical lock is designed for protective armored doors. Thanks to a reversible latch bolt, it is suitable for both right-hand and left-hand door opening. The body is made of galvanized steel, and the lock bolts are made of nickel-plated steel. There is an option to add two additional rods for upper and lower locking (crab system). The electric latch bolt operates on AC 12V, 3.1A, resistance 3 ohms, frequency 50-60Hz, insulation class F, powered via a 15W transformer. An impulse supply (button press) of no more than 1 second is required to open the lock. If the impulse lasts longer, the electromagnetic element of the lock will fail. Such a case is not subject to warranty repair. The lock is equipped with a gear reduction unit, which makes key turning smooth and very easy.

Expert Review

This lock justifies all stated characteristics and is definitely worth its money. We use it for armored doors of 5th-6th anti-burglary class. In operation, it has proven itself to be a reliable and durable mechanism. If the door is subjected to constant attacks, we have specially developed a set of cylinder protectors and armored trims for this lock. With them, it can withstand prolonged attacks without losing its operational capability. This lock is most often used in offices where increased protection, full access control, and remote opening are required. The electrical part of the lock itself uses no more than 15% of its potential and has a large safety margin because only the latch bolt that operates from the handle is blocked. Overall, we are satisfied with the Cisa 15535 lock and recommend it for use with protective doors.
