Many exit control locks are based on magnetic locks. One type, delayed egress magnetic locks, will not allow the door to open immediately. This allows a guard to get to the door before the door opens. It will also release if there is a fire alarm or power failure, but otherwise these locks hold the exit doors shut. These units are common in ...
New standards for Egress Control Systems and Key Management Systems. Revised tests for power supply overload and endurance, as well as updates to the Destructive Attack Test. These updates ensure that UL 294 stays current with technological advancements and changing security needs, ensuring that access control systems provide reliable and ...
For example, when used on the rear service door of a business, a worker whose hands are being used to carry bulky items can lean against a bar to release the lock. While the public generally prefers automatic doors, they can be costly to install and maintain. [20] Some manufacturers offer crash bars designed to resist microbial growth.
The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. The magnetic lock relies upon some of the basic concepts of electromagnetism.
Entrance to HM Prison Edinburgh. A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens.
Locking hardware, such as electric door strikes and electromagnetic locks; A magnetic door switch for monitoring door position; Request-to-exit (RTE) devices for allowing egress. When a RTE button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened.
Door locking hardware - Electrified locks, electric strikes, or maglocks physically secure doors and release when valid credentials are presented. Integration allows doors to unlock when authorized. Request to exit devices - These allow free egress through an access point without triggering an alarm.
Also called fail-locked or non-fail safe. In this configuration, applying electric current to the strike will cause it to unlock. In this configuration, the strike would remain locked in a power failure, but typically the mechanical lock can still be used to open the door from the inside for egress from the secure side.
