Security Doors Key Terms
Understanding terminology related to security doorsPossessing knowledge of security doors can help you make more informed decisions about buying the right types of security doors for your business or for adding hardware to increase the level of security in the doors you already have. Understanding the terminology associated with security doors will help you focus in on what you need and find it quicker.
This guide includes six terms commonly associated with security doors: lock bumping, anti-passback, classroom function, electric strike, ANSI/BHMA grading system and ALOA.
Anti-passbackAnti-passback is a feature available for security doors that prevents someone from using an access card or code to enter a room or building and then passing the card back to another to permit access. An anti-passback code or card allows a person to use the card to gain entrance, but then the code or card can't be used for entrance to the same room or building again until it's first used to exit the same room or building. Security doors that incorporate anti-passback require separate hardware devices for entry and exit.
Classroom functionWith regard to doors, classroom function is a door handle or knob that can only be locked or unlocked from the outside using a key; a classroom function door can't be locked from the inside. Classroom function locksets got their name from the original concept - protecting children in classrooms by not permitting them to be in a room from which they couldn't escape in the event of fire or some other emergency.
Electric strike or strikerAn electric strike is a door locking device typically operated by solenoid power, that unlocks a door whenever electrical power is applied.
ANSI/BHMA grading systemThe Builders Hardware Manufacturers Association/American National Standards Institute grading system is a method for rating the level of security provided by door hardware based on voluntary performance standards developed and maintained by BHMA, an ANSI-accredited organization. The ANSI/BHMA standards establish door hardware product grades that demonstrate progressive performance benchmark levels. The purpose of each grade is to help identify lockset quality and durability through several security and operational tests. There are three basic lock grades: 1-3. 1 represents the highest level of security and 3 represents basic residential security.
ALOAALOA is the acronym for the Associated Locksmiths of America. ALOA is an international trade association for those employed in the locksmith/access control industry.
