This Tann TBT Bankers Treasury 1600S entirely new safe will progressively replace the Mark 9 Bankers Cash Safe. It has increased body thickness with grid reinforcement. The door is similarly strengthened and provided with devices to deter all forms of attack including thermic cutting. The TBT is specifically designed for heavy duty protection and use in banks but is also very suitable for general high risk purposes.
The body comprises a monolithic structure with an overall thickness of 125mm (5") on all sides. The monolithic all round protection contains drill and torch resistant alloys in slab formation, reinforced against delamination attack by a heavy steel reinforced grid interlocked at each corner to give a continuous protective cage. This heavy reinforce­ment is embedded within Tann Adamantium. The protective alloy slabs have a thickness of 25mm (1") minimum to a maximum of 45mm (1 25/32") in main bolt locking areas. As a final protection against skinning, steel grids are welded to the inside face of outer body plates suitably embedded within the Adamantium. The complete structure gives all round protection against known forms of attack.
The door is designed to give a maximum thickness of 120mm (4 3/4") over the lock and boltwork, of which 55mm (2 3/16) is metal content, and comprises an electrically welded steel carcass containing barrier materials to give a resistance against attack by drills, all forms of oxygen cutting, impact and other forms of attack.
As an added protection against side attack through the body on the locks additional protective plates are added within the lock chamber. Traditional style hinges with self lubricating bearings ensure easy movement of the door.
In standard form locking is effected by two locks, either Tann Series 20 nine lever keylocks or four number code combination locks; both locks operate live relocking devices. Full glass plate protection is given to the sensitive areas of the lockwork. Connected to the glass plate by seven strand stainless steel wire are four dead relocking devices, three of which are positioned at random.
The safe, both externally and internally, is finished in an attractive semi-gloss colour with stainless steel cross panel and bright finish.
