ATB Safes

ATB Alcazar Modular

Demountable grade 4 safe (EN 1143-1, ECB·S), assembled on site

The ATB Alcazar Modular is the demountable version of our ATB Alcazar: a grade 4 safe that is delivered in parts and assembled on site. This lets you install a heavy safe where a one-piece safe cannot get through the door, up the stairs or into the lift. Assembly does not reduce the resistance: the safe is ECB·S certified to EN 1143-1 in grade 4.

The door and body are 50 mm thick. The door locks with Ø 25 mm rotating steel bolts, from 12 to 45 depending on the model, and is protected against drilling. In the event of an attack, a relocker blocks the bolt work. An M16 anchor (100 kN) is included.

There are ten sizes, from 178 to 2303 litres. Models APD-6 to APD-10 have one door and are 1100 to 1700 mm high. The APD-11 has a double door and the APD-12, 1950 mm wide, a four-part folding door. Inside are height-adjustable shelves; options include a 100 mm pull-out drawer and a key rack with an identification system. The door with its frame is also available separately, as a small vault door or to build a large built-in safe.

Like every grade 4 safe, the Alcazar Modular has two EN 1300 class B locks: two key locks, a key lock with a mechanical or electronic combination lock, two electronic locks, or a key lock with an electronic lock with time delay and blocking. More information on our safe locks. Our own team handles delivery, assembly and anchoring.

Frequently asked questions

Our safes are almost always anchored chemically: a high-tensile threaded rod is bonded into the floor or wall with a two-component mortar, with the diameter and length carefully matched to the substrate. We drill through the floor finish, screed and insulation into the concrete slab, thoroughly clean the borehole and fill it with mortar; after curing, this creates an extremely strong connection — with higher pull-out strength than mechanical plugs. Anchoring is more than just fixing the safe in place: for safes up to 1000 kg it is even mandatory under EN 1143-1, because an unanchored safe can simply be carried away. If the substrate is unsuitable, we provide adapted plinths or mounting constructions. Read more on our delivery, installation and anchoring page.

Atelier Boonen takes care of the delivery, installation and anchoring of safes entirely in-house. We never use external transporters or installers. Using specialised transport equipment, we deliver discreetly and safely, including to upper floors or hard-to-reach locations. Safes are always wrapped in opaque film and transported in unmarked vehicles to avoid curious eyes.

For safes up to 1000 kg, anchoring is mandatory under the European standard EN 1143-1. We carry out this anchoring carefully, using chemical anchors or adapted solutions depending on the substrate. Where necessary, we use stair climbers and protective materials to safeguard floors, walls and staircases.

The installation is always carried out safely, efficiently and with respect for the building. This guarantees you a professionally executed installation offering the strongest and most durable solution. In 95% of cases, delivery, installation and anchoring are included in the price — at no extra charge.

A safe with a code lock is also known as a digital safe or combination safe. Locking is done by an electronic code lock or a mechanical combination lock. Key-operated safes are also available, as are combinations of both. The right choice depends on your daily use and the security grade of your safe.

From grade 4 onwards, two safe locks are mandatory — a combination of key lock and code lock, or two code locks. For lighter safes, a second lock can be added as an option.

  • Electronic locks: user-friendly, the code is easy to set and change, often with multiple codes, time functions, audit trail and alarm connection.
  • Mechanical locks: the classic mechanical dial lock — extremely reliable and durable, less prone to faults, but slower to operate and more complex when changing the code.
  • Key locks: suitable as an additional lock, but rarely recommended as the only lock.

A mechanical safe lock works without power. You enter the code with a dial. The lock needs no battery, lasts a long time and is not prone to faults. Opening it does take some practice, and the code is changed with a change key.

An electronic safe lock opens with a code on a keypad. This is quicker, and you change the code yourself. Depending on the model, several user codes, a time delay, time locks, an audit trail and an alarm connection are possible. The lock runs on a battery that you replace from time to time.

Both types are available certified to EN 1300, so the choice mainly depends on how you use the safe: how often you open it, how many people use it, and whether you want to see who opened it and when. See our mechanical locks and our electronic safe locks.
