Fire protection module

Description
When MEDIATOR locks are used on fire doors, the fire protection module 519ZBFS (item no. 022711) is required.
In the event of a fire or power failure, the module ensures that the status of the motorised lock changes to locked from whatever status it was in and that the door can fullfil its fire safety function. It goes without saying that the panic function via the door handle or push bar will remain functional.
For smoke recognition a smoke alarm system or a smoke detector with a relay output must be connected.
