In response to the growing use of computers and electronic technology in access control, the Builders Hardware Manufacturers Association (BHMA), New York City, recently released ANSI/BHMA A156.25 American National Standard for Electrified Locking Devices, setting performance requirements for motors, solenoids, and various other electrical components used in electrically activated locks. The mechanical components of such locks are still covered by the applicable pre-existing standards.
The standard includes descriptions and definitions as well as discussions of functions for various types of products that belong in the category of electrified locking devices. The test allow manufacturers to identify and certify the type and grade of their products, including whether or not the products are suitable for outdoor use.
