User Manual Series F-BO-AFE70 Chapter 9 • Connection and parameterisationFig. 13: Connection of two Automatic Purging Units F-BO-AFE70 in the master-slave mode.A … Aspirating smoke detector (in order to provide a clearer overview, only the connections thatare absolutely necessary for the Purging unit are shown)The two relay contacts are shown in the state where no voltage is being provided to therelays.B … Power unit for the aspirating smoke detector (observe the country-specific regulationsregarding the power supply of aspirating smoke detectors and special detectors)C … Fire alarm message to the fire detection control panel (observe the connection conditionsfor the fire detection control panel used)D … Fault message to the fire detection control panel (observe the connection conditions for thefire detection control panel used)E … Actuation output on the fire detection control panel (observe the connection conditions forthe fire detection control panel used)This output is used to start the Purging processes if the ASD experiences a fault.Manual Purging activations can be carried out by manipulating operating devices that areintended for this purpose, provided that this feature has been prepared by the installer of thesystem.F … In addition, the fault outputs of the F-BO-AFE70 can optionally be connected to the firedetection control panel in order to transmit the fault of the F-BO-AFE itself (through wirebreakage of this fault detector line).The aspirating smoke detector, the master unit as well as all slave units can be powered by differ-ent power supplies or by the same power supply.If several Purging units, each with its own independent power supply device, are operated with acommon timer for synchronising the time or with a common push-button „Manual activation“ orsomething similar, the supply voltage minus terminals of the Purging units (terminal 2) must beconnected to each other.I56-4252-010D200-104-0035
