ATB Alcázar – high-security burglary resistant safe (Grade 4, EN 1143-1, ECB·S)
The ATB Alcázar range consists of high-security Grade 4 burglary resistant safes, designed for professional applications requiring an enhanced security level. These safes are officially certified by ECB·S according to the European standard EN 1143-1, Grade 4, providing proven resistance against both mechanical and thermal burglary attacks.
Each safe in the Alcázar range is built with a multi-layer steel construction, reinforced with armour plates, internal steel structures and a core of UHPC (Ultra High Performance Concrete). The door is secured with a three-sided locking system using solid steel bolts, while fixed bolts on the hinge side prevent attacks from that direction. A passive relocking system automatically activates in the event of a burglary attempt.
A fire-resistant intumescent seal around the door and frame provides additional protection against heat, smoke and flames.
The ATB Alcázar Grade 4 range includes 9 models with capacities from 46 to 620 litres. All safes are equipped with EN 1300-certified Class B locks. In accordance with the standard, each Grade 4 safe must be fitted with at least two Class B locks, which may be two key locks, two code locks (mechanical or electronic), or a combination of both.
Thanks to their solid construction, dual-lock configuration and official European certification, the ATB Alcázar Grade 4 burglary resistant safes are the ideal choice for users requiring a higher level of security, both in professional environments and for demanding private use.
