Door defense systems consist of devices designed to deter and prolong a break-in attempt. Some of the sophisticated systems Champion Safe uses are:

Inner Door Steel: A quality safe will have a full layer of inner door steel.

Hardplate Lock Protection: Pieces of hardened steel plate are placed between the inside of the safe’s door and the lock. The goal is to protect the lock from drilling or punching. In the safe industry three types of hardplates are generally used: Case-hardened mild steel, Ball Bearing, and Diamond hardplate. Of these three types of hardplate, diamond provides the highest level of protection. Champion uses only diamond hardplate on all its models.

• Diamond-Embedded Armor Plate™–Industrial diamond is bonded to a tungsten steel alloy hardplate. Diamond is harder than either a cobalt or carbide drill. If drilling is attempted the diamond removes the cutting edge from a drill – thus dulling the drill bit to where it will not cut.

Relockers: A relocker is a device that locks up the safe’s boltworks when activated by heat, force to the lock or by drilling. Champion uses several types of relockers:

• Glass Relocker–Tempered glass is placed between the inner door steel and the lock. If broken, through drilling or punching, it releases a secondary mechanical system which prevents movement of the boltworks.

• Heat Relocker–S&G® locks have an insert that melts at a low temperature, preventing movement of the boltworks.

• Mechanical Relocker–This spring-loaded relocker is mounted on the back of the safe’s lock. If the back of the lock is forced off, it releases, locking up the boltworks.

• Remote Relocker–This system is attached to either a mechanical or glass relocker, but is located at random locations inside the safe’s door.

Lock Pressure Relievers: This device prevents pressure applied direct to the door bolts from damaging the safe’s lock.
Clutch Drive System: The clutch system is designed to prevent handle pressure from damaging the safe’s inner mechanism and lock.

For door defense systems to be optimally effective, a safe must have a strong steel foundation. Even the most sophisticated anti-break-in systems are ineffective when used on lightweight safes.
