• A UHF/ HID/Mifare/RFID reader installed near the entry.
• Locking hardware, such as Electric door strikes, Bolt locks, Shear locks, Rim Locks and Electromagnetic locks.
• A magnetic door switch, door contact or reed switch for monitoring door position.
• Request-to-exit (REX / Push Button / Break Glass / Push bar / Panic Button) devices for allowing egress. When a REX button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door.
