The NF series is American Securities mid-level safe design and tends to be one of the most popular models they offer. The NF model features 4 different size and capacity options to fit just about any application
The fire protection rating of the NF series is 90 minutes at 1245°. I generally suggest having an absolute minimum of 60 minutes of fire protection in any scenario so this provides ample protection. Instead of using composite material to resist fire, the NF series uses 4 layers of gypsum board on the top and bottom of the safe, 3 layers in the walls and 3 layers in the door. Also included is a two stage fire seal that protects your valuables from heat and smoke damage by expanding nearly 7 times it’s size completely sealing all four sides of your safe door. Most people will find that this just the right amount of fire protection for the application.
To keep your valuables protected from a break-in, American Security has included a wide array of security features that are uncommon among store bought mid-level safes. The door of the NF series starts with a ¼” steel plate on the exterior of the door backed with three total layers of fire resistant gypsum board. The door secured tightly to the safe by 9 – 1 ½” chrome plated bolts and 5 deadbolts that protect all 4 sides of your safe from being pried open. The body of the safe is made from 11-gauge solid steal to protect all sides of your safe from blunt force. The locking mechanism is a U.L. listed group II lock that incorporates a hard plate and two relocking devices. These great security features have earned the NF series the U.L Residential Security Container burglary classification.
