ISM Jewelers Mk 7
The Jewelers Mk 7 was designed to offer sophisticated protection against all forms of physical and thermic attack. ISM has incorporated in this safe superior composite materials and a unique locking mechanism to produce a high security safe with superb six-sided burglary resistant properties.
The overall thickness of the Jewelers Mk 7 door is 150 mm (6"). It is constructed of outer and inner steel plates of 10 mm (0.4") thickness each electrically welded together and enclosing a 30 mm (1.2") thick casting of C.N.A. ISM's superior torch and drill resistant composite material. The C.N.A. was developed by ISM to withstand all forms of attack by force, drills, and oxy-acetylene cutters. It consists of a tough thermal resistant cast alloy within which a consistently staggered drill resistant alloy multi-grid is incorporated, covering the whole area of the door.
The ISM Jewelers Mk 7 body features a 25 mm (1") thick casting of C.N.A. ISM's superior torch and drill resistant composite material. In addition is a 30 mm (1.2") thick layer of ISM's CS-300 Monolith reinforced with a steel grid. Thus bringing the total thickness of the body to 75 mm (3"). Together these materials, encased inside and out with steel plates that are electrically welded, form a unit highly resistant to attack by drills and thermic cutting tools.
Boltwork and Locking Mechanism
The ISM Jewelers Mk 7 is equipped with a three way active boltwork of a unique design which provides the bolts an independent form of protection against not only explosive attack but also from concentrated tool attacks from all directions. The bolts are 30 mm (1.2") in diameter of high-strength steel and are nickel plated. By turning the handle to the locking position the bolts are extended by a sliding mechanism which moves perpendicularly to the bolts thus providing a positive defense barrier against bolt attack. The bolts in the locking position are each extended into their C.N.A. chamber which ensures complete solidarity with the body.
The locks and vital mechanism areas are protected against tool, torch, or explosive attacks by a tempered glass plate. The glass if attacked will shatter into pieces, thus activating the random relockers. In addition two live relockers are activated if the locks are attacked. All the relockers have cross locking pins which will not allow them to be withdrawn after being activated.
The ISM Jewelers Mk 7 is equipped with a U.L. MP Group 1 maximum security combination lock. A second nine lever double-bit key lock is provided in conjunction with the combination lock. When the door of the safe is closed, it is impossible to remove the key without securing the bolts in the locking position, thus ensuring that even if the combination lock is not engaged, the safe is secure. As an optional extra all models (except the 2416 size) are prepared to accept a three movement 144 hour timelock that locks the safe independent of any other lock. This prevents holdups after hours.
Adjustable/removable shelves are available for setting up the safe interior to accept jewelry trays, cash trays, rolled coins and other valuables.
A modern anodized aluminum capstan wheel operating handle and facia panel compliment the durable paint finish, standard on all ISM Security Equipment.
