ISM Treasury Mk 3 Safes
The ISM treasury Mk 3 safe is the result of ISM's striving to develop advanced products that anticipate new security needs. The Mk 3 is ISM's second generation TRTL—30X6 safe designed for low-weight limited locations using sophisticated composite barrier materials.
The overall thickness of the door is 190mm (7.51”). It is constructed of outer and inner 10 mm (0.4') thick steel plates continuously welded together, enclosing a 70mm (2.75") thick casting of Alchronite ISM's patented superior torch and drill resistant material. Additional protection's provided by a frame of copper bars in the door jamb area.
The body features a unique one piece bell casting of Alchronite of a 55 mm (2.2") thickness going up to a maximum thickness of 125 mm (5") at the boltwork protective area. In addition the body is constructed with a dense layer of Insutex, ISM's superior insulation material to protect the safe's contents against severe fires.
The Treasury Mk 3 is equipped with a U.L. listed group 1 Manipulation Proof combination lock. A second nine lever double-bit key lock is provided in conjunction with the combination lock. As an optional extra all models (except the 2618 & 3722) accept a time lock.
The boltwork and locking mechanism were designed to give maximum protection against explosive attacks from all directions. The safe has a three way moving boltwork with fixed bolts on the hinge side of the door.
The locks and vital mechanism areas are protected by a special glass plate which if tampered with releases a number of randomly located relockers independent of the locks. This provides the safe with a maximum security deterrent.
Adjustable/removable shelves are available for setting up the safe interior to accept trays for jewelry, cash, and other valuables. Each ISM Treasury Mk 3 has an inner vault activated by a key lock.
