Usage
The BB Locks A1 Basic 25 SX electric lock is designed for high-security applications where doors must remain locked during power outages. It is ideal for securing entrances in banks, prisons, labs, and other sensitive or restricted access areas.
Advantages
- Ensures permanent locking in the event of power failure (fail-secure principle)
- Mechanical unlocking via cylinder possible at all times, even under side pressure
- High lateral force resistance up to 40,000 N for enhanced protection against forced entry
- 20 mm bolt throw with hardened anti-saw pin and robust stainless steel components
- Integrated position monitoring of bolt and door improves access control systems; requires a dedicated power supply installation distance of up to 25 m[1][3][5]
Specifications
- Milled stainless steel baseplate and components; protected electronics encapsulated in polyurethane resin[1][4]
- Cyclic endurance tested to over one million operations (600 cycles per day); certified EN14846 and suitable for use on fire/smoke doors per EN1634-1 standards[3][4]
- 24V DC operation with activation current of approximately 2.2A (0.2s) and holding current less than 130mA; supports backsets from 25mm[1][5]
- Lateral force resistance up to approximately 40 kN; equipped with automatic relocking when the door closes using Hall sensors for detection [3][5]
How it works
The lock operates electrically: upon closing the door, integrated sensors detect position and activate an instant locking mechanism with a strong steel bolt. Electrical control manages opening functions while mechanical override by key remains available at all times.[1][5]
