Special Function Cylinders - Classroom and Anti-Barricade

​

We supply a lot of additional functions on our cylinders at Secure Arc as we know that sometimes your customers have additional requirements. Two of the most popular features we supply are the classroom function and the anti-barricade function. Both cylinders can be added to any new or existing suites and are available in 70mm or 80 mm euro profile cylinder and turn.

 

Classroom Function Cylinder

​

The purpose of the classroom cylinder is to provide an extra level of security on lockable doors. The cylinder has a turn on the inside of the door which will only operate in one direction (clockwise or anti-clockwise) in order to UNLOCK the door. This prevents occupiers from being accidentally or purposely locked in a room. The key will always operate the lock from the outside, being able to lock and unlock. This is often used in a classroom to avoid a situation where children lock the door from the inside of the classroom, requiring a key to come and unlock the door from the outside. There is no way of locking the door from the inside so this cannot happen. The clutch release mechanism ensures that somebody in the room cannot prevent a keyholder from entering.

Anti-Barricade Function Cylinders

 

The anti barricade clutch thumbturns were designed with secure accommodation and the health sector in mind. These products offer a level of privacy to end users whilst maintaining their safety and security. Anti barricade cylinders enable a door to be locked with the thumbturn from the inside of a room, however should somebody need to get in to the room from the outside they are able to override the locking mechanism with the key even if it is being held from the inside. This works insomuch as if the client attempts to grip the thumbturn to prevent staff operating the lock from the other side, the sprung clutch mechanism releases once the key is entered and allows the key to turn.
