Great security for pistols, ammo and valuables at home, on the road or in the office. Solid steel, pry resistant, plate steel doors, steel live action locking bolts and concealed hinges provide greater security. The electronic lock includes a dashboard faceplate that makes it easy to view the status of your safe. The key pad will "beep" when a button is touched- letting you know you have pressed a key. The "beeps" can be turned off or on with the press of the megaphone button. There is a time out period after 3 incorrect combination attempts. Your safe includes a backup key should your batteries lose power or if you forget your combination. Combinations can be changed easily by pressing a button located on the back of the door and entering a new combination. There are pre-drilled holes for mounting the safe to the floor/shelf and wall. Fastening hardware is included. Safes should be mounted to a solid surface to ensure the security of their contents. These safes are California-approved Firearm Safety Devices that meet the requirements of Penal Code section 23655 and the regulations issued thereunder.
