What is the Deadlatch on a Panic Bar?

A panic bar, also known as an exit device or crash bar, is a safety device that allows people to quickly exit a building in the event of an emergency. The deadlatch is a component of the panic bar that is designed to keep the door securely closed when it is not being used for egress. In this guide, we will discuss the deadlatch on a panic bar in more detail and its importance in maintaining building security.

What is a Deadlatch?

A deadlatch is a type of lock that is commonly used on commercial doors. It consists of a spring-loaded bolt that is operated by a key or handle from the outside and a thumb turn on the inside. The bolt engages with the strike plate on the door frame, keeping the door securely closed until the key or handle is operated.

Deadlatch on a Panic Bar

On a panic bar, the deadlatch serves an important role in maintaining building security. When the panic bar is not being used for egress, the deadlatch keeps the door securely closed, preventing unauthorized access. However, when the panic bar is pushed, the deadlatch retracts, allowing people to quickly and easily exit the building.

Importance of Deadlatch on Panic Bars

The deadlatch on a panic bar is an essential component for maintaining building security. It ensures that the door remains securely closed when not being used for egress, preventing unauthorized access. This is particularly important in high-security areas, such as laboratories, data centers, and secure storage rooms.Additionally, the deadlatch on a panic bar helps to prevent accidental exits. If the door is not securely closed, it may open unexpectedly, causing people to exit the building unintentionally. This can be dangerous, particularly if the building is in the midst of an emergency situation. The deadlatch helps to prevent accidental exits, ensuring that people only exit the building through designated egress points.
