The EN 1125 push bar, commonly known as a panic exit device, is a critical safety mechanism for emergency doors. Its defining feature is a wide, horizontal bar that spans the door leaf. In an emergency, occupants can open the door instantly and intuitively by simply applying body pressure to the bar, triggering the internal mechanism to release the lock. This "push-to-open" design ensures rapid and panic-free evacuation. Compliance with the EN 1125 standard guarantees the device meets rigorous requirements for strength, durability, and reliability, making it an essential safeguard for public safety in buildings.
