11.4. POTENTIAL-FREE ALARM CONTACT
NOTE:
The potential-free alarm contact is used to connect a signal to a control centre/control room. Direct
integration into a fire alarm control panel (FACP) is not recommended or may only be carried out in consul-
tation with the person responsible for the system.
However, it is always recommended to connect the signal to a manned control centre/control
room!
The potential-free switching contact must always be connected by the customer (not a service).
