The Door Forced Feature is an important part of an access control system. It is designed to activate an alarm if the door is opened without a valid access card being presented or an associated REX (Request to Exit) signal. This feature is especially useful in case of forced entry by criminals who may forcibly attempt to open the door.

A local door sounder is a siren device that provides an audio alert when a protected door is held open past a preset time period, typically 15-30 seconds. Its purpose is to promptly and effectively alert individuals that a door has been held open for an extended period. By doing so, it not only prevents unauthorized access but also ensures that the security of the premises remains intact.

A REX device, short for Request to Exit, is a device in access control systems that provides a simple and convenient way to exit through access-controlled doors. A REX device is required for any door secured with a magnetic lock (mag lock). This ensures that individuals inside a secured area can exit in an emergency.

Panic hardware is a type of locking hardware designed to allow immediate exit at all times and is a crucial component of building safety. Its primary purpose is to provide a quick and efficient means of escape during emergency situations. Unlike traditional locking mechanisms, panic hardware allows individuals to exit a building swiftly without the need for any lever or knob rotations. The simplicity and reliability of panic hardware make it an indispensable part of any building's safety infrastructure.

Access control is a crucial component of physical security. It is an electronic system that controls the entry or exit of an area. With access control, only authorized personnel are granted entry to restricted areas, which can include a company's main entrance, server rooms, storage areas, and other sensitive locations.

Access Credentials are devices that contain an encoded ID number that can be captured by an access reader. They are an essential component of modern access control systems, providing a convenient and secure way for individuals to gain access to restricted areas. These devices are designed to store and transmit identification data, which is then captured by an access reader. Some of their different forms include cards, fobs, tags, or mobile apps that can be easily carried around. One of the key advantages of access credentials is the range of encoding technologies they utilize. These devices utilize one or more encoding technologies such as proximity, smart card, magnetic stripe, or Wiegand to store and transmit identification data. Proximity technology, for instance, allows individuals to gain access simply by holding their access credential close to the reader, while smart card technology provides enhanced security through the use of encryption and authentication protocols. With the advent of mobile technology, access credentials can now be stored on mobile apps, making them even more convenient and accessible. With DGAPass, you can easily control access levels for each individual user along with schedules. For instance, you could give Employee A access to your retail location between 8 am and 9 pm and Manager A access from 4 am to 11 pm and so on. Each access point (or door) is also 100% customizable so you can limit who can access storage areas, for instance. All of this can be done at any time on the DGAPass web portal and mobile app.

In access control, fail-safe is a locking method that defaults to the unlocked or open position when power is removed or interrupted. Access systems are universally required by code to revert the locking methods to the fail-safe position upon a fire alarm activation to ensure a safe, fast exit for those inside the premises. This is often done with an electromagnetic lock (mag lock). This locking method consists of a powerful electromagnet and an armature (a metal plate). It is typically used in building entry doors or glass doors where the electromagnet is installed on or in the door frame and the armature is attached to the door. When electrified, the electromagnet keeps the door in a locked position. When a mag lock’s electromagnet loses power, the door will remain unlocked. Overall, fail-safe locking systems are crucial in ensuring safety and reliability, and they are essential for your fire safety compliant access control system.
