Disengageable Cylinders at Thirard

What is a Disengageable Cylinder?

A disengageable cylinder, also known as an anti-panic cylinder, emergency function cylinder, or synkro cylinder, offers less restrictive usage compared to traditional lock cylinders. It functions even when a key is inserted on the opposite side, eliminating the worry of being locked out due to a key left in the cylinder. This feature is particularly beneficial in emergency situations where immediate access is needed, such as providing assistance to someone inside a locked room.

How Does a Disengageable Cylinder Work?

Inside the cylinder, a mechanism allows the bit to disengage, enabling the lock to be operated from the outside even if a key is engaged on the inside. When a key is inserted from the exterior, the internal key follows the movement and pivots simultaneously. This double safety clutch system ensures that you can always unlock the door from the outside, providing peace of mind and enhanced accessibility.

Security Considerations

A disengageable cylinder does not compromise the security of your lock. The presence of a key inside the lock does not make it easier to pick from the outside. The idea that leaving a key in the door enhances security is a myth; picking a lock with a key inserted inside is no more difficult than picking a lock without one. Non-disengageable cylinders simply prevent access to someone with a key only when intentionally left in the door by the occupant.

Practical Uses

Disengageable cylinders are highly practical in various scenarios:

• Elderly, Disabled, or Mobility-Impaired Individuals: Provides access in case of emergencies, preventing unwanted confinement or allowing for quick assistance.
• Children and Adolescents: Ensures they can be accessed easily if they accidentally lock themselves in a room.
• Public Establishments: In places like hotels, where access by emergency personnel such as firefighters is crucial during incidents like fires.

These cylinders are often mandatory in public buildings for safety compliance.

Button Cylinder vs. Disengageable Cylinder

A button cylinder, with a knob on the inside, is inherently disengageable because it cannot be blocked from the inside. A clutch or button cylinder allows for external operation in all situations, ensuring continuous access.

Emergency Function

An emergency function cylinder requires a slight turn to align the mechanism and re-engage the bit. Though it may appear to spin in a vacuum, the key aligns to engage the lock, making it a reliable backup rather than a comfort feature.

Availability and Customization

Not all cylinders come with a disengageable function as standard, though many models do. For those that don’t, Thirard offers customization options to fit your specific needs. Contact us to discuss making your cylinder disengageable.
