Description

Mortice lock, panic B, for connecting or corridor doors. In daytime and night-time operation, the external lever handle can be coupled or decoupled via the cylinder by turning a key in the unlocking direction until it stops. Exiting from the panic side is always possible using the panic function.


Note: Thumbturn cylinders must not be used, except E-thumbturn cylinders with cam resetting. When using a standard cylinder, the key must always be removed. Lever handles must be fixed rotating on plates/roses (easyfix®).
